Accountproxyinterface drupal 8

The web is progressing and it has become quite intense for interaction between clients and websites or apps, multiple sites, databases and devices. For that the internet was demanding a new technology. One such technology which can handle this type of interaction is REST. To learn how to create custom web services, we would create a custom module exposing RESTful API which can display a list of taxonomy terms from our Drupal 9 site. We are now moving forward towards implementation of a rest resource using the GET method.

Drupal 8 or 9 Save data to the content type from a custom module

We saw in a previous post how to set up a publishing process on Drupal 8 with the modules Content moderation and Workflows. We will address here a similar problematic but relying this time on the module State machine , module that will allow us to set up one or more business workflow on any Drupal entity. Note that the state machine module is one of the essential components of Drupal Commerce 2. It will thus remain to implement certain logics so that the fields thus created fulfill their role at best.

In particular, we will have to generate the different permissions allowing us to assign rights to each transition or to adopt a different logic concerning rights management, which could for example be based on certain users's attributes and still trigger actions appropriate for each active status for a content or any entity.

Note that you may need to apply this patch to have a generic event propagated by the State machine field. If not, you can still simply use propagated standard events, events based on the transition ID triggered.

Unlike the Content Moderation and Workflow modules now integrated into the core of Drupal, where we can achieve everything in a few clicks, business workflow configuration with State machine requires the creation of a custom module to declare workflows and a small part of Site Building that we will discuss later briefly.

This module will have this basic structure. A state machine workflow must be part of a workflow group. For each of the workflows we will declare the different states of the workflow under the key states as well as the different possible transitions between these states under the key transitions. We will then be able to control the various rights to access these transitions very finely.

We have with the file above a standard process, classic, and expected by the State machine module. But as it is a manual configuration using a YAML file of a Workflow Plugin State Machine module, nothing forbids us here to add arbitrary properties that will make our business process even smarter. We will only have to detect the presence of these arbitrary properties and their value during the propagation of State machine events. For example, we will associate with certain statuses several properties that may be useful in our wprkflow:.

But I think you understand the principle: we can do everything according to the business needs. For example, our processes will now look more like this, with these new properties that we added for the purposes of the business workflows we want to implement. Just add a State field on the type of entity for which we want to set up a workflow.

Here we will create a State machine field Publication status on the content type Article. We can configure the form display mode to position the State machine field, and in the example below, we also take this opportunity to disable the native Published field, which will no longer serve us directly.

We can also configure different display view modes for the State machine field by displaying the value of the current status here for a Publication status field or by choosing to display a form that gives access to the different possible transitions here for another field that we have created also: Technical status directly from the content's view page.

By default, State machine does not offer any type of permissions for transitions. By default, all transitions are available to users who can edit a State machine field. To control access to transitions, just create one or more services that will implement GuardInterface. And it is through this service that we can simply prohibit access to transitions, according to our logic.

For the example, we will first take a simple case and generate as many permissions as there are possible transitions. The goal is to propose from the permissions management interface checkboxes to assign user roles access to certain transitions. It only remains to create our service that will control access to transitions on the basis of these permissions. Our file also contains some other services on which we will have the opportunity to return.

Note that your service must be assigned to a workflow group using the group key. The main and only method to use is the allowed method that must return FALSE when you want to deny access to a transition under certain conditions. Otherwise the method should not return anything to allow other services collected by the State Machine GuardFactory to also evaluate their condition.

But we could as well have done without all this logic based on standard Drupal permissions, and evaluate the access to transitions according to much more complex criteria while avoiding a lot of clicks on the management interface of Drupal permissions. Once the implementation of access rights to transitions has been achieved, we will be able to finalize our business workflows by triggering the required actions.

Once the fields are created and linked to the workflows, permissions set up, all that remains is to use the Symfony2 event system, available on Drupal 8. Each State machine field will propagate several events during each transition: a pre-transition event and a post-transition event.

It is this last event that we will use in our example. To react to these events, we will implement an EventSubscriber service, which can be found in the service declaration file of our module below.

We will also use another WorkflowHelper service, which will contain some utilitarian methods. Let's discover the WorkflowTransitionEventSubscriber class that will allow us to react according to the different transitions. To do this, we check our custom properties that we associate with the different states of the workflow using the isWorkflowStatePublished method of the WorkflowHelper Utility class.

This last method will inspect the plugin settings for the current workflow, and check if the current status has the published:true property. For example, should we notify some referenced users from a certain field? We will then recover the identifier of the field referencing them:.

In a few lines and some methods, we can now implement any necessary reaction based on a transition and a particular status, let's remember, on any entity of Drupal 8. Which solution to choose between Content moderation and State machine?

We were able to see it during this long presentation of the State machine module, this solution is primarily oriented Drupal 8 Developer , in contrast to the Content moderation solution, more oriented Drupal site builder, which allows to set up a workflow a few clicks even though this solution can be extended by additional developments as well. For their support and predictable maintenance, Content moderation as a Drupal 8 core module has an undeniable advantage.

But the State machine module is not left out because it is one of the major building blocks of Drupal Commerce 2. These two solutions are therefore guaranteed to be in the landscape of the Drupal ecosystem for a certain time.

Be that as it may, this aspect should not be a major element in a decision between a particular solution. Do not hesitate to contact a Drupal 8 expert who can advise you on the best strategy to adopt in relation to your project. If you wish, you can recover the source code of the examples presented in this post on this GitHub repository. There is not a better solution.

It depends on your needs. Rechercher Rechercher. Accueil Blog Set up workflows with State machine on Drupal 8. Set up workflows with State machine on Drupal 8 Partager sur. The operation of the module is quite simple in its design: Workflows must be defined in a custom module using a YAML file: these workflows contain both the different possible states and the different possible transitions between each state.

The module provides a new field type: a State field. We can add as many state fields as needed to an entity, and we can configure which workflow each field will use. And now every time a State field is changed, an event will be propagated see Drupal 8 and events , and we can then act on these events and trigger as many actions as needed It will thus remain to implement certain logics so that the fields thus created fulfill their role at best.

Let's take a closer look at how state machines work. Creating workflows Unlike the Content Moderation and Workflow modules now integrated into the core of Drupal, where we can achieve everything in a few clicks, business workflow configuration with State machine requires the creation of a custom module to declare workflows and a small part of Site Building that we will discuss later briefly. Initial configuration Just add a State field on the type of entity for which we want to set up a workflow.

And we configure this field to use one of the workflows that we declared in our module. Management of access rights on transitions By default, State machine does not offer any type of permissions for transitions. Create the PublicationGuard class.

In short, possibilities are multiples, within range of a few lines. Setting up business logic Once the fields are created and linked to the workflows, permissions set up, all that remains is to use the Symfony2 event system, available on Drupal 8.

As decoupled approaches like mobile and Javascript apps continue to rise in popularity, it will become increasingly important for both backend and frontend developers to gain familiarity with the Drupal REST module and some of its quirks. This part is much more challenging than any of the technical issues I encountered. Once you identify the set of UX components that need data from the API, try to identify common patterns across different components. Fortunately, it works, at least for relatively simple directives. For a pager on a decoupled app to work, you need to know the size of the result space. Unfortunately, the REST module does not have an option to send a results count along with its response. Fortunately, it is pretty simple to make it work.

Recently I was preparing some events to intercept requests in Symfony and sharing some approaches with my colleagues. Then I discovered that in my environment the topic of Event Management in Drupal dispatching events, subscribing events was not very known, so I prepared some snippets to share and from there I thought to write some introductory article. Undoubtedly, in the latest versions of Drupal, certain components of Symfony have not only made their appearance, but also have been gaining importance and surely this will extend further in time, given its elasticity and fully integrated OOP approach. One of these components is the HttpKernel, a very valuable subsystem for building request-response relationships in a technology Silex, Symfony, Drupal.

Drupal 8, add an image field from a BuildForm with preview – Code Utility

See the Drupal class. Note that the current user is not the user entity , it is just user proxy. You can get some basic information from it but fields or other entity-specific logic is not present. To access the user entity you have to load it manually:. Example of how to load current user and retrieve field data from user object. However, DI isn't very intuitive and takes a while to understand.

How to deal with block cached for anonymous user?

Every Drupal site builder works with blocks. Blocks are an essential building component in Drupal. Block configuration allows for the site builder to determine various conditions in which the block should be shown. Some examples are to show the block only for a given content type, a given role, or a given path. The Drupal block configuration page, with a custom condition for "Group member". This tutorial will show how to create this custom condition.

public function AccountProxyInterface::setInitialAccountId in Drupal 8

Today I would like to play a little with the forms in Drupal 8 , taking advantage of them and walking around interesting concepts such as the injection of services and services by themselves or dynamic queries to database. The first step is to decide what kind of forms we want to build. In Drupal 8, there are -basically- three types of forms that, in turn, are constructed from three specific classes:. Class FormBase. Class ConfigFormBase. Class ConfirmFormBase. In this case, we will opt for a form created as Basic Form , more adaptable and elastic for general purposes.

Drupal 8 is a great platform for storing structured data and exposing web service endpoints. This offers Drupal a competitive advantage when creating a decoupled application or building Drupal as part of a larger enterprise of systems. Core offers many complementary out-of-the-box features to publish web services and configure them in different ways. Since Drupal is so robust out of the box, it often minimizes the need for custom development.
