Topic: DrupalLocation: China

I just spent the past week in China, and I thought I'd share a few reflections on the state of Drupal in China.

First, let me set the stage. There are 1.35 billion people living in China; that is almost 20 percent of the world's population. Based on current trends, China's economy will overtake the US within the next few years. At that point, the US economy will no longer be the largest economy in the world. China's rapid urbanization is what has led to the country's impressive economic growth over the past couple of decades and it doesn't look like it is going to stop anytime soon. To put that in perspective: China currently produces and uses 60 percent of the world's cement.

In terms of Drupal, the first thing I learned is that "Drupal" sounds like "the pig is running" ("Zhu Pao") in Chinese. Contrary to a pig's rather negative reputation in the West, many Chinese developers find that cute. A pig is a more honorable sign in Chinese astrology and culture. Phew!

In terms of adoption, it feels like the Drupal community in China is about 8 to 10 years behind compared to North America or Europe. That isn't a surprise, as Open Source software is a more recent phenomenon in China than it is in North America or Europe.

Specifically, there are about 5 Drupal companies in Shanghai (population of 21 million people), 3 Drupal companies in Beijing (population of 23 million people) and 5 Drupal companies in Hong Kong (population of 7 million people). The largest Drupal companies in China have about 5 Drupal developers on staff. Four of the 5 Shanghai companies are subsidiaries from European Drupal companies. The exception is Ci&T, which has 40 Drupal developers in China. Ci&T is a global systems integrator with several thousand employees worldwide, so unlike the other companies I met, they are not a pure Drupal play. Another point of reference is that the largest Drupal event in China attracted 200 to 300 attendees.

Given that China has 4 times the population of the US, or 2 times the population of Europe, what are we missing? In talking to different people, it appears the biggest barrier to adoption is language. The problem is that Chinese Drupal documentation is limited; translation efforts exist but are slow. The little documentation that is translated is often outdated and spread out over different websites. Less than 20 percent of the Chinese Drupal developers have an account on Drupal.org, simply because they are not fluent enough in the English language. Most Drupal developers hang out on QQ, an instant messaging tool comparable to Skype or IRC. I saw QQ channels dedicated to Drupal with a couple thousand of Drupal developers.

There is no prominent Chinese content management system; most people appear to be building their websites from scratch. This gap could provide a big opportunity for Drupal. China's urbanization equals growth -- and lots of it. Like the rest of the economy, Drupal and Open Source could be catching up fast, and it might not take long before some of the world's biggest Drupal projects are delivered from China.

Supporting Drupal's global growth is important so I'd love to improve Drupal's translation efforts and make Drupal more inclusive and more diverse. Drupal 8's improved multilingual capabilities should help a lot, but we also have to improve the tools and processes on Drupal.org to help the community maintain multi-lingual documentation. Discussing this with both the Drupal Association and different members of our community, it's clear that we have a lot of good ideas on what we could do but lack both the funding and resources to make it happen faster.

Special thanks to Fan Liu (Delivery Manager @ Ci&T), Jingsheng Wang (CEO @ INsReady Inc.) and Keith Yau. All the Drupal people I met were welcoming, fun and are working hard.

Every developer has a slightly different approach to building their Drupal sites. I’ve tried just about every approach, and they all have their merits, but my favorite is Drush Make. Before joining Acquia, I didn’t realize Acquia Cloud supported Drush Make, but I was delighted to discover that I was wrong. Assuming I’m not the only person who had missed this fact, I wanted to spend a little time highlighting where this exists and how I’m using it.

Almost everything we do on the web will work better with autonomous blockchain technologies such as Bitcoin & ethereum because they allow systems to be built with unbreakable rules. Unlike Facebook, Twitter, Airbnb, Uber, PayPal or eBay, no executive authority can step in and say the rules don't apply to you.

Of all the blockchain technologies, Bitcoin is currently the most high profile. It is a massive area of growth in the startup eco-system.

Drupal 8 is going to be a fantastic platform for building startups, but we need to make sure that it is also a fantastic platform for blockchain startups.

I've started by creating a Drupal 7 & 8 project called Coin Tools. It provides various components that would be useful for building a Bitcoin web product. Many of the altcoins are very similar to Bitcoin so the project could easily be extended to accommodate them.

I've also created a Blockchain BoF at DrupalCon Amsterdam on the Tuesday at 10:45.

Coin Tools base module

Contains the following field types:

• Address
• Amount
• Transaction

Widgets

Formatters

Coin Tools Daemon

• facilitates configuration and access to bitcoind service
• triggers a hook when a Bitcoin transaction is detected
• provides a full UI for browsing transactions and sending and receiving bitcoin

I am currently working on a full implementation of BIP 70 which provides a much improved payment experience for the customer. Then I will add integration with Payment / Commerce. This means it will be possible to receive payments in Commerce without using a third party payment processor.

Coins Tools Fiat

• obtains bitcoin exchange rates from BitcoinAverage (which I consider to be the gold standard), falling back to BitPay BBB
• facilitates rendering of fiat amounts
• user can select preferred fiat currency
• current bitcoin value block

If you would like help developing your Bitcoin startup on Drupal, please get in touch.

More and more articles with these words are appearing right now: here's our approach for a front-end theme complying with Web good practices.

Unlike DrupalCon Austin, there is no separate UX track at DrupalCon Amsterdam. Ruben and I had to balance both design and development into one track. It was challenging, but it forced us to be really careful about every decision remade.

We really wanted there to be an overlap between sessions, frontend development and design are closer than ever in the workplace, so we wanted to reflect that in our session line up.

Here are a few sessions we think complement each other really well.

The State of the Frontend

Not sure what to learn or where to start in frontend development? Let David and Brian guide you through the landscape, introducing new tools and techniques.

We've also planned this session as an introduction to the entire track, pointing signposts towards other sessions in that track that can fill in more in-depth knowledge about particular subjects. I would encourage everyone with an interest in frontend development to attend the session if only to better understand which sessions in the frontend track are right for them.

We also have a few session that compliment and feed in to each other. Here are a few sessions we think work really well together.

Because it's about the interactions. (Better UX through prototyping) & Axure Prototyping for Drupal

How do we shift from an old design process to a new one while keeping our clients and team members happy? Roy Scholten, UX co-maintainer for Drupal Core, walks us through why prototyping is a better way to design and how to introduce this into your work life.

Then, in Axure Prototyping for Drupal, Dani Nordin takes us on a deep dive of Axure, a prototyping tool you can use without coding. I've been using it recently on a client project and I've been impressed with the way it introduces some concepts of frontend development without asking you to write code.

The Future of HTML and CSS

As a designer, knowing the limits and capabilities of your medium is important, also it means you can call your developers out when they hit you with “That's not possible” which is fun. If you're interested in seeing where web browsers are heading and finding new tricks to add to your repertoire, Preston's talk on The Future of HTML and CSS should be a treat.

Getting a CLUE at the Command Line

As a designer/front-end dev, I've never had a formal education on the command line, it's always been something I've picked up as I've needed it. It used to scare me. This is me using the command line a few years ago:

I'm so happy Emma Jane is talking on the command line in Getting a CLUE at the Command Line in the same vein as her introduction to Git at DrupalCon Prague last year. The command line is an immensely powerful and productive tool and I'm looking forward to picking up a few tips.

Open Source Design

Something I've struggled with, both in my day job and as the maintainer of Drupal's admin theme is how do we bring successful design together with Open Source. I'm really happy that Jan-C. Borchardt, agreed to speak at DrupalCon and share his knowledge and experience with us. Jan is a big supporter of usability and design in free and open source software, with projects including A guide to Usability in Free Software, OwnCloud, Libre Projects, and the brilliant Terms of Service; Didn't Read.

It's really important for Drupal for us to gain insight from people outside the community and learn from other projects. Thanks again Jan for agreeing to speak! I can't wait!

Dru(pal)sh(ell) is an essential tool if you are working with Drupal intensively. If you don't know it yet, Drush is command line shell and scripting interface for Drupal. It helps you to quickly perform various administation and maintenance tasks using only a terminal. If you are not convinced, you should probably install it and give it a try. You won't regret it. It's awesome and will save you headaches, time and again more time. If you are using Drush, you must have been using the command "drush cc all" like a million time. I have. But Drush can do much more.

Perhaps the most important development is the final naming of what was field/field instance in Drupal 7: in Drupal 8 these are configuration entities. The machine names are field_storage_config and field_config. There has been several renames but we have settled on these finally (although the field_config rename is not yet in). It does reflect the most important difference between them: field storage contains everything pertaining to the storage of the field. The things that do not change the storage of it go into the instance. However, some confusion might come from already existing Drupal 8 documentation and other materials where field_config was the name for what ended up as field_storage_config.

In other rename news, entity storage/list/form/render "controllers" are now handlers. This probably decreases confusion as controllers are used by the router system to deliver the page content.

Migrate now tracks the whether a migration has been run or not. Previously we were guessing from the id mappings -- but if a source returned zero rows we couldn't really say whether the migration ran or not. Now we could clarify for real what are hard dependencies and what are optional. In the Drupal 6 migration, there are few optional ones which is just as it should be.

There's a Views migration in the works. As expected it's really complicated with lots of moving parts but it's coming along nicely.

Only book storage needs entity field query conversion after the epic comment query conversion issue finally got resolved.

One of the child issues of the last beta blocker removes the special casing for SQL storage -- hurray! Instead of requesting the schema of entity tables during module install (and other places) and then creating the tables there are now events on entity type create, update and delete. This makes it possible to create mongodb indexes cleanly.

Sunday, 14th September 2014Case Study - NickJr. Colour CMS & API - Feedback sought!

It's been an embarrassing amount of time since I last blogged or did anything to my site so I've started to create some content, but before I submit it as a case study on Drupal's site I'd love to have some feedback, it's been years since I wrote case studies so a little rusty. Is it of interest? Does it help? Does it answer the right questions? Are there any questions you'd like me to answer?

Brief overview

Viacom’s Nick Jr. is a digital television channel aimed younger children, home to popular shows including Dora the Explorer, Angelina Ballerina, and PAW Patrol. 'Colour' is a section of the Nick Jr. website where, daily, tens of thousands of users interact with predefined line-art drawings using paint brushes and stickers. They can then, if they wish to, send pictures they create to their friends via email. The mostly Flash-based front-end currently connects to a legacy back-end system which is being replaced with Drupal.

Completed Drupal site or project URL

http://www.nickjr.co.uk/create/#!/colour

Why Drupal was chosen

Drupal's core and contributed modules along with customisable web administration interface provided all the functionality required out-of-the-box and is already used widely throughout the organisation.

Describe the project (goals, requirements and outcome) Project Goals

The goal of this project was to provide a bespoke back-end CMS based on Drupal to replace the legacy system, along with introducing new functionality enabling Send to Gallery and Pic of the Week features. The CMS needed to as simple as possible for content managers to use, and the whole system had to be able to cope with the tens of thousands of users using the API on a daily basis.

Deliverables

The site was to be delivered as a Drupal install profile so it can be adapted and re-used – an initial step towards creating internal Nickelodeon-specific distributions of Drupal, further lowering costs and time-to-market for future projects with similar requirements. Purkiss built a similar system a few months prior for Universal Artists uView Augmented Reality App and have extensive experience integrating Drupal with 3rd party services so were ideally placed to deliver this type of Drupal project.

Theme

First we set up the install profile with Shiny, the administration theme which comes with Drupal Commerce Kickstart, to be the main theme to the site. Shiny is a great theme for this kind of system where there's really only one main display the content managers interact with – it's easy on the eye with good typography and spacing.

Legacy Migration

We then re-created what functionality was required from the legacy system using Drupal Services – the calls for saving images, retrieving images for a show, etc. There was a major difference here as the legacy system stored all the data in flat XML files with no user data linked. Drupal is a relational database system so we have user accounts, content types and taxonomies – this proved to be an exercise in both education of the client as to the benefits of hooking into the Drupal API, along with re-architecting of the current content model and workflow.

Features

We used a Features-based approach to development with each of these features, along with the install profile, having their own private Git code repository in the cloud in order for issue tracking and maintenance to be easier.

The features we delivered were as follows:

• Content Types
  • NickJr Colour Image – stores the user’s image along with a Canvas ID which refers to the line art used, a taxonomy field to link to the associated show, and two flags – one to show if the user has sent the image in to Nickelodeon for consideration to be included in the showcase, and one to denote whether it is in the associated show’s showcase.
• Fields
  • User Profile Fields – extra profile fields to store the user’s name and age.
• Rules
  • Redirect after login – redirects to the front page view after logging in.
  • Pic of the Week – Views Bulk Operations Component – one rule to set and one to unset an image as Pic of Week
  • Showcase – one to set and one to unset an image as to be in a Show's Showcase
• Services
  • NickJr. Colour API – the Services settings for the custom API endpoints.
• Taxonomy
  • Shows Taxonomy – with Pic of the Week field
• Variables
  • Always harmonize views filters – Allows views to use both contextual and exposed filters for views
• Views
  • Front Page – Displays all images, defaults to only show images Sent to Nick
  • Showcase – Displays images in showcase, all if no show_id sent through
  • User Profile – Displays users images on their profile page

Schedule

Project timescale and budget was for an incredibly tight 10 days which we delivered in, however were subsequently hired for a further 7 days to re-factor the API and provide a few final additions to the administration interface.

Out-of-the-box, Drupal Services module provide a standard set of API calls so you can do things like create a user, a node, etc. so all the functionality required was there however required a number of calls to the API to achieve the desired workflow. It was decided to spend extra time creating custom API endpoints which would hide this functionality, reduce the number of API calls required, and make it easier for future users of the API.

The downside to this approach is the technical debt introduced when diverting away from the *.drupal.org infrastructure of support, i.e. core and contributed modules. In this instance the code was simply wrapping existing API calls and the client has access to technical resources so the decision was to take on the technical debt in order to produce a more tailored outcome.

Outcome

We used the extra time to create a RESTful API which abstracted away from Drupal Services out-of-the-box API endpoints along with coding an auto account creation system to link up user data from the front-end without users having to enter their email address, a requirement of Drupal’s user account creation. We documented the API using Drupal’s inbuilt help module and passed the system over to the client, helping them through building the system from the Drush make file.

Summary

The resulting system is a clean, simple-to-use CMS with RESTful API handling thousands of users on a daily basis. Content managers have a separate role with very restricted access so can only do what they need to do on the system.

We really enjoyed delivering this project, however alert anyone thinking of building similar to allow extra time, especially if it is their first Drupal experience - no matter how good specifications are, issues usually arise in one form or another. Also often once people do start using Drupal and see the possibilities available, requirements change and it is good to allow for those to be taken into account.

features
filter_harmonizer
mimemail
rules
services
shiny

strongarm
views_bulk_operations
views

Why these modules/theme/distribution were chosen

• boolean_formatter – makes the user interface a little nicer by providing icons for boolean fields such as ticks and crosses
• CORS – required for connecting to the front-end
• EVA - we used an Entity Views Attachment to display users pictures on their profiles
• features - features allows you to export configuration settings to code
• filter_harmonizer - Views Filter Harmonizer fixes an issue when using multiple filters on views
• mimemail - used to send images via email
• rules - as described above, used for redirecting user on login and for custom views bulk operations
• services - used for the RESTful API
• shiny - an administration theme we are using for the entire site
• smtp - for sending email
• strongarm - for storing variables in features
• views_bulk_operations - to enable easy workflow, such as adding an image to a showcase
• views - so we can display the data we want easily

Community contributions

As the API is specific to the client and used mostly existing functionality we had no code to contribute. The only custom code was for automatic account creation and there are existing modules which provide similar functionality which we used the code from but is too specific to this install to re-use externally.

This is however the second time we’ve been asked for this sort of system, and with the growth of mobile apps we are currently working out whether it would be possible to create a distribution which will help get most of the way there - at least have relevant modules and perhaps an example scenario based on the simple image requirements for this project.

Consolidating Content Fields in Drupal

Migrating from Tumblr to Drupal

PHP 5.5 introduces generator functions.  Generator functions return an object that can be iterated over - often to be used with a foreach loop, for example:

function gen_one_to_three() { for ($i = 1; $i <= 3; $i++) { // Note that $i is preserved between yields. yield $i; } }   $generator = gen_one_to_three(); foreach ($generator as $value) { echo "$value\n"; }

Which will output:

123

(Example taken from php.net).

PHP calls the generator function when it needs values - when the generator yields a value the state of the generator is saved, so it can then be resumed when the next value is required. This can lead to significant performance boosts over creating an array which only exists to be looped over as less memory is needed.

There is more detail on http://codingexplained.com/coding/php/introduction-to-php-generators.

So how can this apply to Drupal …

A render array might look like...

$wrapper = array( '#type' => 'container', '#attributes' => array( 'class' => array('class'), ), ‘item-one’ = array ( … ); ‘item-two’ = array ( … ); ‘item-three’ = array ( … ); );

The element_children function returns an array which contains the array keys of the children array elements. This breaks from the standard PHP foreach pattern where you perform operations directly on the value created by the foreach loops - I don’t think this is ideal - I had to look twice to see what was happening the first time I saw it.

Using generators, you can use a more typical php pattern - the following is equivalent to the above.

foreach(element_children_generator($variables) as $key => &$element) { ... $element[‘#example’] = ‘example’; dpm($element); ... }

As well as being a more typical PHP pattern, referencing the element within the loop is cleaner.

There are downsides to this approach too. A developer familiar with Drupal may have to look twice to see what is going on with the yield keyword. Obviously this can’t go into Drupal 7 Core (which supports php 5.2.5+), and I wouldn’t recommend it for Contrib either for the same reason. 

However since PHP 5.3 and below is EOL I think this pattern is well worth adopting in your own projects with low risk.

Drupal distributions can be a huge leg up in building a website, especially for those with little technical knowledge. The “ingredients” (modules) you need are already assembled, leaving you with just the task of stirring it up, and perhaps adding your own personalizing flavors. The Open Outreach distribution is specifically designed for nonprofit and grassroots groups. It comes with a wide range of apps — bundles of modules and configurations that are geared to the needs of groups, such as contact management or mapping. It also includes a number of helper features, such as a text editor, commenting, and social media handling.

For more detailed instructions on how to work with Open Outreach, see the complete user documentation.

Below you’ll find some recipes for whipping up a specific kind of Open Outreach site, giving you the apps you need: to enable; required configuration; suggested themes for the look and feel of your site; and tips on customizations to take your site further. Happy site building!

Environmental group focused on mining impacts

You’re a board member of this small but enthusiastic group. You’ve been tasked with creating a website that will serve as the public face, but more importantly also track membership contacts as well as your contacts with other groups, government bodies, and industry.

Wow my Hungarian friends - you have done it again! Two weeks ago, I spent a long weekend at Drupalaton, a Drupal camp in Hungary with the difference that it also served as a short relaxing break. It was the perfect combination of a holiday and work with the beautiful surroundings of Central Europe’s largest lake Balaton.

I was very excited to return to the country after the amazing Drupal Developer Days in Szeged event that I went to in March. It was also filled with meeting amazing people from all around the world, learning and sharing knowledge and connecting with so many inspiring people.

At both events the thing that really stood out for me was the great hospitality shown by the Hungarians I met there. I have really been humbled by how friendly and hospitable they have been, and all of the time they put into making the event so amazing for all the attendees.

This was the fifth year that large Drupal events have been taking place in the country, but the second where the language hasn’t been exclusively in Hungarian. Last year’s event brought people from Romania, Serbia and other neighbouring countries but this year we had a much more international event with people from Austria, Belgium, Finland, Germany, Spain, & the UK in attendance.

The team that made it happen

Tamás ‘York’ Pintér, was the main organiser and lives in the area of the camp, Zsófi Major co-ordinated many aspects of the event including community outreach over social media & sponsorship management, István Csáki, helped to create the website and other support, Bálint Fekete, made some amazing design work (in particular the innovative scroll on the website where the boat moves across the page which I spent far too long playing with!).

Also on the team were Gábor Hojtsy, (Drupal 8 multilingual initiative lead) helping with event-marketing, István 'PP' Palócz who helped with finances (and helped me learning some basic Hungarian phrases) and last but not least Tamás ‘TeeCee’ Szügyi, the photographer who documented the great event.

Some numbers

In the recent newsletter to all attendees from the organisers the following statistics were disclosed.

"We are really proud of the following numbers, so let us share with you:
Our 79 attendees came from 13 countries from all over the world, and only a bit more than half of them were from Hungary. This lucky number is significant for us, as Drupalaton started as a local Drupalcamp, and now we can proudly say that we are on the big Drupalmap :)"

• You spent more than 1420 minutes (almost 24 hours) on 8 workshops with learning.
• The sprinters worked on 70+ issues during the 4 days. This a great number, you can find more thoughts about it in Gábor Hojtsy's blog post.
• During the 4 days you consumed 134 pcs of Túró Rudis, 132 ps of Marzipan ladybugs, 260 cans of beer, 60 kilograms of different fruits and  7 kilograms of nuts."

Next year

If any of that sounds good you should attend next year, 6-9 August 2015, I'm very excited about returning. Even the founder of Drupal, Dries Buytaert, regrets not attending! Maybe he will join us too next year, that would be awesome!

What is code-driven development and why is it done?

Code-driven development is the practice of placing all development in code. How can development not be in code?, you ask.

In Drupal, what makes your site unique is often configuration which resides in the database: the current theme, active modules, module-specific configuration, content types, and so on.

For the purpose of this article, our goal will be for all configuration (the current theme, the content types, module-specific config, the active module list...) to be in code, and only content to be in the database. There are several advantages to this approach:

• Because all our configuration is in code, we can package all of it into a single module, which we'll call a site deployment module. When enabled, this module should provide a fully workable site without any content.
• When a site deployment module is combined with generated content, it becomes possible to create new instances of a website without cloning the database. Devel's devel_generate module, and Realistic Dummy Content can be used to create realistic dummy content. This makes on-ramping new developers easy and consistent.
• Because unversioned databases are not required to be cloned to set up new environments, your continuous integration server can set up new instances of your site based on a known good starting point, making tests more robust.

Code-driven development for Drupal 7

Before moving on to D8, let's look at a typical D7 workflow: The technique I use for developing in Drupal 7 is making sure I have one or more features with my content types, views, contexts, and so on; as well as a site deployment module which contains, in its .install file, update hooks which revert my features when needed, enable new modules, and programmatically set configuration which can't be exported via features. That way,

• incrementally deploying sites is as simple as calling drush updb -y (to run new update hooks).
• deploying a site for the first time (or redeploying it from scratch) requires creating the database, enabling our site deployment module (which runs all or update hooks), and optionally generating dummy content if required. For example: drush si -y && drush en mysite_deploy -y && drush en devel_generate && drush generate-content 50.

I have been using this technique for a few years on all my D7 projects and, in this article, I will explore how something similar can be done in D8.

New in Drupal 8: configuration management

If, like me, you are using features to deploy websites (not to bundle generic functionality), config management will replace features in D8. In D7, context is used to provide the ability to export block placement to features, and strongarm exports variables. In D8, variables no longer exist, and block placement is now exportable. All of these modules are thus no longer needed.

They are replaced by the concept of configuration management, a central API for importing and exporting configuration as yml files.

Configuration management and site UUIDs

In Drupal 8, sites are now assigned a UUID on install and configuration can only be synchronized between sites having the same UUID. This is fine if the site has been cloned at some point from one environment to another, but as mentioned above, we are avoiding database cloning: we want it to be possible to install a brand new instance of a site at any time.

We thus need a mechanism to assign the same UUID to all instances of our site, but still allow us to reinstall it without cloning the database.

The solution I am using is to assign a site UUID in the site deployment module. Thus, in Drupal 8, my site deployment module's .module file looks like this:

/** * @file * site deployment functions */ use Drupal\Core\Extension\InfoParser; /** * Updates dependencies based on the site deployment's info file. * * If during the course of development, you add a dependency to your * site deployment module's .info file, increment the update hook * (see the .install module) and this function will be called, making * sure dependencies are enabled. */ function mysite_deploy_update_dependencies() { $parser = new InfoParser; $info_file = $parser->parse(drupal_get_path('module', 'mysite_deploy') . '/mysite_deploy.info.yml'); if (isset($info_file['dependencies'])) { \Drupal::moduleHandler()->install($info_file['dependencies'], TRUE); } } /** * Set the UUID of this website. * * By default, reinstalling a site will assign it a new random UUID, making * it impossible to sync configuration with other instances. This function * is called by site deployment module's .install hook. * * @param $uuid * A uuid string, for example 'e732b460-add4-47a7-8c00-e4dedbb42900'. */ function mysite_deploy_set_uuid($uuid) { \Drupal::config('system.site') ->set('uuid', $uuid) ->save(); }

And the site deployment module's .install file looks like this:

/** * @file * site deployment install functions */ /** * Implements hook_install(). */ function mysite_deploy_install() { // This module is designed to be enabled on a brand new instance of // Drupal. Settings its uuid here will tell this instance that it is // in fact the same site as any other instance. Therefore, all local // instances, continuous integration, testing, dev, and production // instances of a codebase will have the same uuid, enabling us to // sync these instances via the config management system. // See also https://www.drupal.org/node/2133325 mysite_deploy_set_uuid('e732b460-add4-47a7-8c00-e4dedbb42900'); for ($i = 7001; $i < 8000; $i++) { $candidate = 'mysite_deploy_update_' . $i; if (function_exists($candidate)) { $candidate(); } } } /** * Update dependencies and revert features */ function mysite_deploy_update_7003() { // If you add a new dependency during your development: // (1) add your dependency to your .info file // (2) increment the number in this function name (example: change // change 7003 to 7004) // (3) now, on each target environment, running drush updb -y // will call the mysite_deploy_update_dependencies() function // which in turn will enable all new dependencies. mysite_deploy_update_dependencies(); }

The only real difference between a site deployment module for D7 and D8, thus, is that the D8 version must define a UUID common to all instances of a website (local, dev, prod, testing...).

Configuration management directories: active, staging, deploy

Out of the box, there are two directories which can contain config management yml files:

• The active directory, which is always empty and unused. It used store your active configuration, and it is still possible to do so, but I'm not sure how. We can ignore this directory for our purposes.
• The staging directory, which can contain .yml files to be imported into a target site. (For this to work, as mentioned above, the .yml files will need to have been generated by a site having the same UUID as the target site, or else you will get an error message -- on the GUI the error message makes sense, but on the command line you will get the cryptic "There were errors validating the config synchronization.").

I will propose a workflow which ignores the staging directory as well, for the following reasons:

• First, the staging directory is placed in sites/default/files/, a directory which contains user data and is explicitly ignored in Drupal's example.gitignore file (which makes sense). In our case, we want this information to reside in our git directory.
• Second, my team has come to rely heavily on reinstalling Drupal and our site deployment module when things get corrupted locally. When you reinstall Drupal using drush si, the staging directory is deleted, so even if we did have the staging directory in git, we would be prevented from running drush si -y && drush en mysite_deploy -y, which we don't want.
• Finally, you might want your config directory to be outside of your Drupal root, for security reasons.

For all of these reasons, we will add a new "deploy" configuration directory and put it in our git repo, but outside of our Drupal root.

Our directory hierarchy will now look like this:

mysite .git deploy README.txt ... drupal_root CHANGELOG.txt core ...

You can also have your deploy directory inside your Drupal root, but keep in mind that certain configuration information are sensitive, containing email addresses and the like. We'll see later on how to tell Drupal how it can find your "deploy" directory.

Getting started: creating your Drupal instance

Let's get started. Make sure you have version 7.x of Drush (compatible with Drupal 8), and create your git repo:

mkdir mysite cd mysite mkdir deploy echo "Contains config meant to be deployed, see http://dcycleproject.org/blog/68" >> deploy/README.txt drush dl drupal-8.0.x mv drupal* drupal_root cp drupal_root/example.gitignore drupal_root/.gitignore git init git add . git commit -am 'initial commit'

Now let's install our first instance of the site:

cd drupal_root echo 'create database mysite'|mysql -uroot -proot drush si --db-url=mysql://root:root@localhost/mysite -y

Now create a site deployment module: here is the code that works for me. We'll set the correct site UUID in mysite_deploy.install later. Add this to git:

git add drupal_root/modules/custom git commit -am 'added site deployment module'

Now let's tell Drupal where our "deploy" config directory is:

• Open sites/default/settings.php
• Find the lines beginning with $config_directories
• Add $config_directories['deploy'] = '../deploy';

We can now perform our first export of our site configuration:

cd drupal_root drush config-export deploy -y

You will now notice that your "deploy" directory is filled with your site's configuration files, and you can add them to git.

git add . git commit -am 'added config files'

Now we need to sync the site UUID from the database to the code, to make sure all subsequent instances of this site have the same UUID. Open deploy/system.site.yml and find UUID property, for example:

uuid: 03821007-701a-4231-8107-7abac53907b1 ...

Now add this same value to your site deployment module's .install file, for example:

... function mysite_deploy_install() { mysite_deploy_set_uuid('03821007-701a-4231-8107-7abac53907b1'); ... Let's create a view! A content type! Position a block!

To see how to export configuration, create some views and content types, position some blocks, and change the default theme.

Now let's export our changes

cd drupal_root drush config-export deploy -y

Your git repo will be changed accordingly

cd .. git status git add . git commit -am 'changed theme, blocks, content types, views' Deploying your Drupal 8 site

At this point you can push your code to a git server, and clone it to a dev server. For testing purposes, we will simply clone it directly

cd ../ git clone mysite mysite_destination cd mysite_destination/drupal_root echo 'create database mysite_destination'|mysql -uroot -proot drush si --db-url=mysql://root:root@localhost/mysite_destination -y

If you visit mysite_destination/drupal_root with a browser, you will see a plain new Drupal 8 site.

Before continuing, we need to open sites/default/settings.php on mysite_destination and add $config_directories['deploy'] = '../deploy';, as we did on the source site.

Now let the magic happen. Let's enable our site deployment module (to make sure our instance UUID is synched with our source site), and import our configuration from our "deploy" directory:

drush en mysite_deploy -y drush config-import deploy -y

Now, on your destination site, you will see all your views, content types, block placements, and the default theme.

This deployment technique, which can be combined with generated dummy content, allows one to create new instances very quickly for new developers, testing, demos, continuous integration, and for production.

Incrementally deploying your Drupal 8 site

What about changes you make to the codebase once everything is already deployed. Let's change a view and run:

cd drupal_root drush config-export deploy -y cd .. git commit -am 'more fields in view'

Let's deploy this now:

cd ../mysite_destination git pull origin master cd drupal_root drush config-import deploy -y

As you can see, incremental deployments are as easy and standardized as initial deployments, reducing the risk of errors, and allowing incremental deployments to be run automatically by a continuous integration server.

Next steps and conclusion

Some aspects of your site's configuration (what makes your site unique) still can't be exported via the config management system, for example enabling new modules; for that we'll use update hooks as in Drupal 7. I'm still having some errors doing this in D8, but I'm working on it!

Also, although a great GUI exists for importing and exporting configuration, I chose to do it on the command line so that I could easily create a Jenkins continuous integration job to deploy code to dev and run tests on each push.

For Drupal projects developed with a dev-stage-prod continuous integration workflow, the new config management system is a great productivity boost.
