Actions

The action is a set of processors that handle a request.

Each action has two required elements:

• context - An object that stores the input and output data and shares data between processors.

• main processor - The main entry point for an action. This class is responsible for creating the context and executing all worker processors.

For more details about these elements, see the Creating a New Action section.

The following table shows all actions provided out-of-the-box:

Action Name	Description
get	Returns an entity by its identifier.
get_list	Returns a list of entities.
delete	Deletes an entity by its identifier.
delete_list	Deletes a list of entities.

update_list	Updates a list of entities of the same type.
get_subresource	Returns a list of related entities represented by a relationship.
update_subresource	Updates an entity or entities (depending on the association type) connected to an entity to which the sub-resource belongs. This action does not have the default implementation, additional processors should be added for each sub-resource

unhandled_error	Builds a response for the case when an unexpected error happens before any public action is started.
batch_update	Used by the update_list action to update/create a set of entities of the same type.
batch_update_item	Used by the batch_update action to update/create an entity that is part of a batch operation.

See the Processors section for more details on creating a processor.

Auxiliary Actions

customize_loaded_data Action

This action makes modifications to the data loaded by the get, get_list and get_subresource actions.

The context class: CustomizeLoadedDataContext.

The main processor class: CustomizeLoadedDataProcessor.

An example of a processor used to modify the loaded data is ComputePrimaryField or Add a Computed Field. Run php bin/console oro:api:debug customize_loaded_data to display other processors registered in this action.

The collection tag attribute can be used for processors of this action to process all primary entities in get_list or get_subresource actions or all entities in to-many associations for get, get_list or get_subresource actions. An example of a case when using this attribute can be helpful if you want to execute one SQL query for all entities in a collection to get additional data instead of executing a separate SQL query for each entity in a collection. The default value the collection tag attribute is false. An example of a processor that should be executed to a whole collection:

services:
    acme.api.process_my_collection:
        class: Acme\Bundle\DemoBundle\Api\Processor\ProcessMyCollection
        tags:
            - { name: oro.api.processor, action: customize_loaded_data, collection: true, class: Acme\Bundle\DemoBundle\Entity\MyEntity }

Important

The collection elements are an associative array, and processors responsible for customizing the collection must keep keys in this array without changes.

Note

All processors for this action have the identifier_only tag attribute set to false. It means that such processors are not executed when loading relationships. If your processor should be executed when loading the relationships, set the identifier_only tag attribute to true. If your processor should be executed when loading relationships, primary, and included entities, set the identifier_only tag attribute to null. For example:

services:
    acme.api.compute_my_field:
        class: Acme\Bundle\DemoBundle\Api\Processor\ComputeMyField
        tags:
            - { name: oro.api.processor, action: customize_loaded_data, identifier_only: true, class: Acme\Bundle\DemoBundle\Entity\MyEntity }

Note

The identifier_only tag attribute is not supported if the collection tag attribute equals true. All processors intended to modify collections are executed when loading primary entities and entities in to-many associations, even if only the identifier field is requested.

Note

The ValueTransformer can be used in customize_loaded_data processors to convert a value to a format suitable for the API response.

customize_form_data Action

Makes modification and validation of submitted data, and entities to be persisted in the database by the create, update, update_relationship, add_relationship and delete_relationship actions.

The context class: CustomizeFormDataContext.

The main processor class: CustomizeFormDataProcessor.

This action is executed when the following Events are dispatched:

Event Name	Description
pre_submit	This event is dispatched at the beginning of the Form::submit() method.
submit	This event is dispatched after the Form::submit() method has submitted and mapped the children, and after reverse transformation to normalized representation.
post_submit	This event is dispatched at the very end of the Form::submit().
pre_validate	This event is dispatched at the end of the form submitting process, just before data validation. It can be used to final form data correcting after all listeners, except data validation listener, are executed and all relationships between submitted data are set.
post_validate	This event is dispatched at the end of the form submitting process, just after data validation. It can be used to finalize the form after all listeners, including the data validation listener, are executed. E.g. it can be used to correct form validation result.
pre_flush_data	This event is dispatched after the database transaction is open but before data are flushed into the database. Do not call EntityManager::persist() and EntityManager::remove() during handling of this event, use addAdditionalEntity() and addAdditionalEntityToRemove() methods of the context instead.
post_flush_data	This event is dispatched after data are successfully flushed into the database but before the database transaction is committed.
post_save_data	This event is dispatched after data are successfully flushed into the database, and the database transaction is committed. It can be used to perform some not crucial operations after data are saved into the database. It means that failure of these operations will not roll back data saved into the database.

Note

All these events use the same context, so it can be used to share data between events.

Note

When a request contains included entities, these events are dispatched for the included entities first and then for the primary entity. Each entity has its own context. Use the getSharedData() method of the Context class to share data between events for different entities.

An example of a processor used to modify the submitted data is MapPrimaryField. You can also run php bin/console oro:api:debug customize_form_data to display other processors registered in this action.

Creating a New Action

To create a new action, to create two classes:

• context - This class represents a context in the scope of which an action is executed. An instance of this class is used to store the input and output data and share data between processors. This class must extend ApiContext. Depending on your needs, you can use another classes derived from ApiContext, for example Context, SingleItemContext or ListContext.

• main processor - This class is the main entry point for an action and is responsible for creating an instance of the context class and executing all worker processors. This class must extend ActionProcessor and implement the createContextObject method. Depending on your needs, you can use other classes derived from ActionProcessor, for example, NormalizeResultActionProcessor.

namespace Acme\Bundle\DemoBundle\Api\Processor;

use Oro\Bundle\ApiBundle\Processor\ApiContext;

class MyActionContext extends ApiContext
{
}

namespace Acme\Bundle\DemoBundle\Api\Processor;

use Oro\Component\ChainProcessor\ActionProcessor;

class MyActionProcessor extends ActionProcessor
{
    /**
     * {@inheritDoc}
     */
    protected function createContextObject(): MyActionContext
    {
        return new MyActionContext();
    }
}

Additionally, you need to register your processor in the dependency injection container:

acme.my_action.processor:
    class: Acme\Bundle\DemoBundle\Api\Processor\MyActionProcessor
    public: false
    arguments:
        - '@oro_api.processor_bag'
        - my_action # the name of an action

If you need to create groups for your action, register them in the ApiBundle configuration. To do this, add Resources/config/oro/app.yml to your bundle, for example:

oro_api:
    actions:
        my_action:
            processing_groups:
                initialize:
                    priority: -10
                load_data:
                    priority: -20
                finalize:
                    priority: -30

Note

The priority attribute is used to control the order in which groups of processors are executed. The higher the priority, the earlier a group of processors is executed. The default value is 0. The possible range is from -254 to 252. For details on processor creation, see the Processors section.
