Morpht: Announcing Entity Class Formatter for Drupal 8

Planet Drupal - 10. November 2017 - 5:06

The Entity Class Formatter is a nifty little module which allows editors to place classes on to entities, allowing their look and feel to be altered in the theme layer or with other modules such as Look and Modifiers. It is now available for Drupal 8.

Entity Class Modifier is a humble little module, however, it does open up a lot of possibilities. The most obvious is to use the theme layer to provide styles for the class which has been applied. This makes it possible for the “designer” at design time to can some different styles to pick from. It is however, possible to use the module in a more flexible way and combine it with Modifiers and Looks.

Once a class has been defined and added to a field, a “Look Mapping” can be defined, associating the class with a set of Modifiers. The site builder or skilled editor can then go in and define any number of Modifiers which will be fired with the class.

For example - a “my-awesome-class” class could be created which is wired into a “field_my_awesome” set of Modifiers. The Modifiers could include a blue linear gradient with white text overlay with generous padding. All of this configuration happens in the UI after deploy. It is a very flexible and powerful system. The system can be configured after deployment and adapted to the styles you wish to apply.

Basic use of Entity Class Formatter

The use of the module is very easy. We can for example define our own class on the article.

The first thing we need to do is to enable the module. Once installation is complete we can go and add our custom field. In this little tutorial we will basically add the class onto the article content type. So go to Structure > Content types > Article > Manage fields and add new text field. We can name the field simply "Class" and save it. As we keep everything in default we can save it on the next page too.

 

Now the last thing we need to do to make it work is set the Entity Class on the field in Manage display page. Go to Structure > Content types > Article > Manage display and change the format to "Entity Class". There's no need to any other manipulation with field because it won't render any values which would be visible to the visitor of the page.

 

That's it! No we can go to create an article (Content > Add content > Article). Input class to our field...

... voila, class is there!

Similar but different

There are a couple of modules out there which are similar but are different enough for them not to be totally suited to our requirements.

Classy Paragraphs, available in Drupal 8, has been influential in the Paragraphs ecosystem and has opened the way for creative designs. It was intended to apply to Paragraphs only and is quite structured in the way classes are applied through a custom field type. The Entity Class Formatter module is more flexible in that it has been designed to apply to all entity types. It can also handle a variety of field types (text, select lists, entity references) and is able to adapt to the data at hand. So, Entity Class Formatter has a similar aim - it is just somewhat more generic.

Field Formatter CSS Class, available in Drupal 7, also uses a field formatter approach to applying the class to the entity. It does have more complexity than this module because it deals with several layers of nesting. The Entity Class Formatter is very simple and only applies to the parent entity of the field.

Entity Class Formatter was inspired by Classy Paragraphs (thanks) and is supported by the team at Morpht.

Acquia Lightning Blog: Optional config weirdness in Drupal 8

Optional config weirdness in Drupal 8 phenaproxima Thu, 11/09/2017 - 12:55

This post was originally published on Medium.

Ah, the config system. Crown jewel of Drupal 8, amirite?

Well, yeah, it’s fantastic and flexible (as is most of Drupal). But if you have advanced use cases — such as building a system that alters config dynamically — there are traps you should know about.

Config is normally a fairly static thing. Your module/theme/profile (“extension” from here on out) has some configuration in its config/install sub-directory, and when the extension is installed, that config is imported. Once it’s imported, that config is owned by your site and you can change it in any way you see fit.

That’s the simplest, and most common, use case in a nutshell. Let’s talk about some other ones.

Optional config

In some extensions’ config directory, you will see an ‘optional’ directory alongside ‘install’. If you look in there, you see…some YAML files. What’s all this, then?

Optional config is normal config, but it’s treated differently. When an extension is installed, each piece of optional config it provides is analyzed, then imported only if all of its dependencies are fulfilled. A piece of config can declare, for example, that it depends on a view called ‘content’. That’d be expressed thusly in code:

dependencies: config: - views.view.content

If that piece of config is optional, then it will only be imported if, well, a view called ‘content’ exists in the system. That view might have been shipped with another extension, or maybe you created it manually. It makes no difference. As long as a view called ‘content’ is present, any optional config that depends on it will be imported as well.

Neat, yes? This comes in quite handy for something like Lightning, which allows you to create an install profile which “extends” Lightning, yet only installs some of Lightning’s components. Optional config allows us to ship config that might be imported, depending on what parts of Lightning you have chosen to install. Hooray for flexibility!

Optional config whilst installing Drupal

But wait, there’s more.

When you’re doing a full site installation (i.e., install.php or drush site-install), optional config is treated a little bit differently. In such a case, all extensions are installed as normal, but their optional config is ignored initially. Then, at the end of the installation process1, once all extensions are installed (and their default config has been imported), all2 the optional config is imported in a single batch.

I don’t think this is documented anywhere, but it can have major ramifications. Consider this piece of code — let’s say it’s part of a module called fubar, which provides some default config and some optional config. This hook will be invoked while fubar is being installed, but after its default config has been imported:

<?php /** * Implements hook_install(). */ function fubar_install() { $view = entity_load('view', 'fubar_view'); $view->setDescription('The force will be with you, always.'); $view->save(); }

fubar_view is optional config, so will entity_load() return a view entity, or will it return NULL? What do you think?

The maddening answer is it depends. It depends on when fubar is being installed. If Drupal is already installed, and you’re just adding fubar to your site, then $view will be a view entity, because the optional config will be imported before hook_install() is invoked. But if you’re installing fubar as part of a full site install — as part of an installation profile, say — $view is going to be NULL, because optional config is imported in a single batch at the end of the installation process, long after all hook_install() implementations have been invoked.

Yeah, it’s a WTF, but it’s a justifiable one: trying to resolve the dependencies of optional config during Drupal’s install process would probably have been a colossal, NP-complete nightmare.

Dynamically altering optional config

So let’s say you need to make dynamic alterations to optional config. You can’t do it in hook_install(), because you can’t be sure that the config will even exist in there. How can you do it?

The easiest thing is not to make assumptions about when the config will be available, but simply react when it is. If the optional config you’re trying to alter is an entity of some sort, then you can simply use entity hooks! Continuing our fubar example, you could add this to fubar.module:

<?php use Drupal\views\ViewEntityInterface; /** * Implements hook_ENTITY_TYPE_presave(). */ function fubar_view_presave(ViewEntityInterface $view) { if ($view->isNew() && $view->id() == 'fubar_view') { $view->setDescription('Do, or do not. There is no try.'); } }

This ensures that fubar_view will contain timeless Yoda wisdom, regardless of whether fubar_view was imported while installing Drupal. If fubar_view is created at the end of the installation process, no problem — the hook will catch it and set the description. On the other hand, if fubar_view is installed during drush pm-enable fubar, the hook will…catch it and set the description. It works either way. It’s fine to dynamically alter optional config, but don’t assume it will be available in hook_install(). Simply react to its life cycle as you would react to any other entity’s. Enjoy!

Moar things for your brain
  • hook_install() can never assume the presence of optional config…but it can assume the presence of default config (i.e., the stuff in the config/install directories). That is always imported before hook_install() is invoked.
  • In fact, you can never depend on the presence of optional config. That’s why it’s optional: it might exist, and it might not. That’s its nature! Remember this, and code defensively.
  • The config_rewrite module, though useful, can throw a monkey wrench into this. Due to the way it works, it might create config entities, even optional ones, before hook_install() is invoked. Even during the Drupal installation process. Beware! (They are, however, working to fix this.)
  • The config system is well-documented. Start here and here. This post is only one of tons of other blog posts about config in D8.
  • This blog post came about because of this Lightning issue. So hats off to Messrs. mortenson and balsama.
  • Thanks to dawehner for reviewing this post for technical accuracy.
  • “NP-complete”, as I understand it, is CompSci-ese for “unbelievably hard to solve”. Linking to the Wikipedia article makes me seem smarter than I really am.

1 The reason this happens at the end is because any number of things could be changing during installation (who knows what evil lurks in hook_install()? Not even the Shadow knows), and and trying to solve multiple dependency chains while everything is changing around you is like trying to build multiple castles on a swamp. (Only one person has ever accomplished it.) Don't think about this stuff too much, or it will melt your brain.

2 “All”, in this case, means “all the optional config with fulfilled dependencies,” not all-all.

Amazee Labs: GraphQL for Drupalers - the basics

Planet Drupal - 9. November 2017 - 18:25
GraphQL for Drupalers - the basics

GraphQL is becoming more and more popular every day. Now that we have a beta release of the GraphQL module (mainly sponsored and developed by Amazee Labs) it's easy to turn Drupal into a first-class GraphQL server. This is the new GraphQL series in which we'll describe the features that are new in beta and provide a detailed overview of the integration with Drupal's entity and field systems.

Blazej Owczarczyk Thu, 11/09/2017 - 17:25

This is the new GraphQL series about the new features that are in beta (published 2 weeks ago) and how they are connected with Drupal out of the box

The modules

Let's start with the modules we need. Recently there were quite a few changes in this field. In alpha we had:

  • graphql - The main module laying the foundations for exposing data using Drupal plugins.
  • graphql_core - which exposed Drupal core data - the info about entity types and bundles, but not fields
  • graphql_content - which handled field exposition with the view modes
  • other auxiliary modules (e.g., graphql_boolean graphql_entity_reference) that provided behaviours for specific field types

In beta, the structure has changed. Now the default schema exposes all the Drupal fields and (content) entities in raw form, using the typed data. Thanks to that GraphQL became a zero-configuration plug and play module. We just need to enable graphql and graphql_core (the only two modules that are shipped with the package now) and we're good to go.

NOTE: The other modules are still available in case you need them, they're just not part of the core package anymore. graphql_legacy is where most of the field modules went. Besides that, there are graphql_views  which lets us expose views, the promising graphql_twig that allows using GraphQL queries without a decoupled setup and a few more. All of the modules are listed in the drupal-graphql organization page on GitHub.

The Explorer

After enabling graphql and graphql_core we can go ahead and test it with GraphiQL; an interactive tool that lets you run queries, see results in real time and preview all the available fields along with arguments and return types. It also provides query validation, autocompletes suggestions and keyboard shortcuts. Thus, it's a kind of an IDE. The explorer is connected with the schema. We can find it next to the Default Schema under: Configuration -> Web services -> GraphQL -> Schemas or using the direct path - graphql/explorer.

This is how it looks. On the left, there is a query box with a comment describing the tool and listing the keyboard shortcuts. Results show up in the box on the right. To run the query we can use the «play» button at the top, or the keyboard shortcut (Ctrl-Enter). One more important piece is the < Docs button in the upper right corner. This is where we can see all the available elements. Let's go ahead and click it.

The only thing we can start with is the query field which is of type RootQuery. Clicking on the type shows a list of available sub-fields, including userById, which looks like this:

This field takes two arguments: an id (which is a string) and a language (which can be set to any language enabled on the site) and is of type User. Clicking on the type brings up a list of fields on a user. The name is a string:

Strings are scalars (which means they don't have subfields) so we can finish our simple query here. It will look like this:

and (after running it with Ctrl-enter) the response is what we'd expect

The GraphQL explorer (or GraphiQL) gives us the ability to easily write and debug every GraphQL query. That's a feature that's hard to overestimate so getting familiar with it is a good starting point to understanding how GraphQL works in general and how we can get our Drupal data out of it.

The Voyager

Voyager is another schema introspection tool, a visual one this time. It draws a chart of all the types and field in the system and presents it in a nice way. It can be found next to The Explorer under: Configuration -> Web services -> GraphQL -> Schemas or using the direct path - graphql/voyager.

That's it for this post. In the next one, we'll see some examples of retrieving data from Drupal fields.

Aten Design Group: Sunshine, Rainbows and Release Cycles: Drupal 9 and Beyond

Planet Drupal - 9. November 2017 - 17:57
Planning for Drupal 9 and Beyond

Justin’s recent post about the product approach and Drupal's new release cycle got me thinking about what upgrading to Drupal 9 will really look like from a more technical standpoint. There's already lots of information out there explaining this new feature. I think there are some misconceptions about what it means for Drupal projects though, so let’s take a little look under the hood.

Background

To understand what the process of updating to Drupal 9 might look like, you'll need to know a few background terms. If you already know what "semver" and "deprecation" mean for a software project, you can skip ahead to "Preparing for Drupal 9".

Drupal now follows semantic versioning. Semantic versioning—semver for short—is a format for assigning numbers to releases. This number signals a promise about the compatibility and/or stability of a release. A semver tag has three parts, a major version number, a minor version number and a patch version number, all separated by periods. For example, a recent version of Drupal was tagged 8.4.0. For this release, the major version number was 8; the minor version number is 4; the patch number is 0. A common misconception is to think that after 8.0.9, one must have 8.1.0, but it’s perfectly acceptable to have a release number like 8.0.107.

What do major, minor and patch mean? We'll look at each from least to most significant.

A patch release signifies a fix.

They are usually composed of small, isolated fixes. When Drupal is on version 8.4.0 and releases version 8.4.1, this indicates that it is a patch release. It means, "nothing in your code needs to change, we just fixed some bugs". These might be security fixes, so you should update to these releases as soon as possible.

A minor release signifies new features and deprecations.

These are my favorite. They're the ones filled with all the sunshine and rainbows. A minor release adds new features and code to Drupal. This might mean an experimental module becomes stable as the Workflow module did in 8.4.0 or—my personal favorite—a new experimental module, like JSON API, might be added to Core. A minor release is an opportunity for Drupal's maintainers to clean things up, to keep Drupal fresh and to ensure Drupal keeps up with the needs of modern applications. It's also an opportunity to deprecate parts of Drupal Core. A deprecation is when a part of Drupal Core gets moved to the graveyard. It will be maintained for security fixes and bugs, but you shouldn't use that part of Drupal any more. It's usually an indication that there are new, better APIs or best-practices you should follow. A minor release says, "we've made things better, we've cleaned stuff up, and we didn't break your stuff yet."

The graveyard of deprecated APIs

A major release signifies incompatible changes.

They can be a cause for celebration or an ominous cloud on the horizon. They're a critical event in Drupal's lifecycle. A major release is a signal that says "Warning: Your Stuff Might Break!" In some software, it might mean you need to rebuild your project. In Drupal 8 and beyond, thankfully, this shouldn't be the case. The maintainers have made a promise that says, "if you're not using deprecated code, you can update without rebuilding." In the past, like from Drupal 6 to Drupal 7, that wasn't the case and things definitely broke.

Preparing for Drupal 9

So, you know what a deprecation is, and what a major version release means. You know that the promise of Drupal's new release cycle is "if you're not using deprecated code, you can update without breaking things." But did you catch the caveat? If you're not using deprecated code. It's here that I believe the most misconceptions lie. I believe that many have confused this promise to mean that projects can be updated to Drupal 9 without a hitch. That the upgrade will be relatively routine.

The truth is that it's really up to you to make it routine and not something to fear.

How you approach your Drupal software project means that this major event in Drupal's lifecycle can be either a midlife crisis or a coming-of-age.

I said earlier that all the sunshine and rainbows are in the minor version releases. That's because you get all the goodies for free. Underneath the hood though, you need to be aware of what's being deprecated. Every time something is deprecated, a little technical debt is added to your project. You should pay that debt as soon as possible. A deprecation is a warning that the code underneath is going to disappear in Drupal 9. It's a warning to module maintainers and project developers that they need to update code that relies upon that newly deprecated API.

This reality is another point in the product approach's favor, as we alluded to in our earlier post. By making an ongoing investment in your project, you can address these deprecations as they happen so that when you're ready to upgrade to Drupal 9, it will be as painless as any other update.

The Prettiest Rainbows Come After a Little Rain

A select few sites will be able to proudly announce their upgrades to Drupal 9 the day it's released or soon after. Many won’t be able to move so quickly.

Knowing that Drupal 9 will break things relying on deprecated code and knowing that many modules won’t have been updated ahead of the release (such is life in open source), many sites will have to be patient. How patient depends on whether they’ve made an ongoing investment in their platform and kept up with deprecations in their custom code. They’ll be able to upgrade even faster if they have been model citizens in the Drupal community by reporting—and hopefully fixing—contrib dependencies on deprecated code too.

So, is this just like every other major Drupal release? Absolutely not! Gone forever are the days of completely rebuilding your site with every major update. Gone are the days of needing to migrate your own content to your own site. What this means is that you’ll just have to sit inside and wait or go play in the rain, fixing some bugs and updating some outdated dependencies, before you get to enjoy the Drupal 9 rainbow.

Here are some helpful links to stay up to date with deprecations:
