Service Configuration
---------------------

When you create a new Admin service you can configure its dependencies, the services which are injected by default are:

=========================     =============================================
Dependencies                  Service Id
=========================     =============================================
model_manager                 sonata.admin.manager.%manager-type%
form_contractor               sonata.admin.builder.%manager-type%_form
show_builder                  sonata.admin.builder.%manager-type%_show
list_builder                  sonata.admin.builder.%manager-type%_list
datagrid_builder              sonata.admin.builder.%manager-type%_datagrid
translator                    translator
configuration_pool            sonata.admin.pool
router                        router
validator                     validator
security_handler              sonata.admin.security.handler
menu_factory                  knp_menu.factory
route_builder                 sonata.admin.route.path_info
label_translator_strategy     sonata.admin.label.strategy.form_component
=========================     =============================================

Note: %manager-type% is to be replaced by the manager type (orm, doctrine_mongodb...)

You have 2 ways of defining the dependencies inside ``services.xml``:

* With a tag attribute, less verbose:

.. code-block:: xml

    <service id="acme.project.admin.project" class="Acme\ProjectBundle\Admin\ProjectAdmin">
        <tag
            name="sonata.admin"
            manager_type="orm"
            group="Project"
            label="Project"
            label_translator_strategy="sonata.admin.label.strategy.native"
            route_builder="sonata.admin.route.path_info"
            />
        <argument />
        <argument>Acme\ProjectBundle\Entity\Project</argument>
        <argument />
    </service>

* With a method call, more verbose

.. code-block:: xml

    <service id="acme.project.admin.project" class="Acme\ProjectBundle\Admin\ProjectAdmin">
        <tag
            name="sonata.admin"
            manager_type="orm"
            group="Project"
            label="Project"
            />
        <argument />
        <argument>Acme\ProjectBundle\Entity\Project</argument>
        <argument />

        <call method="setLabelTranslatorStrategy">
            <argument type="service" id="sonata.admin.label.strategy.native" />
        </call>

        <call method="setRouteBuilder">
            <argument type="service" id="sonata.admin.route.path_info" />
        </call>
    </service>

If you want to modify the service that is going to be injected, add the following code to your
application's config file:

.. code-block:: yaml

    # app/config/config.yml
    admins:
        sonata_admin:
            sonata.order.admin.order:   # id of the admin service this setting is for
                model_manager:          # dependency name, from the table above
                    sonata.order.admin.order.manager  # customised service id


Creating a custom RouteBuilder
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

To create your own RouteBuilder create the PHP class and register it as a service:

* php Route Generator

.. code-block:: php

    <?php
    namespace Acme\AdminBundle\Route;
    
    use Sonata\AdminBundle\Builder\RouteBuilderInterface;
    use Sonata\AdminBundle\Admin\AdminInterface;
    use Sonata\AdminBundle\Model\AuditManagerInterface;
    use Sonata\AdminBundle\Route\PathInfoBuilder;
    use Sonata\AdminBundle\Route\RouteCollection;
    
    class EntityRouterBuilder extends PathInfoBuilder implements RouteBuilderInterface
    {
        /**
         * @param \Sonata\AdminBundle\Admin\AdminInterface $admin
         * @param \Sonata\AdminBundle\Route\RouteCollection $collection
         */
        public function build(AdminInterface $admin, RouteCollection $collection)
        {
            parent::build($admin,$collection);
            $collection->add('yourSubAction');
            // Create button will dissappear, delete functionality will be disabled as well
            // No more changes needed!
            $collection->remove('create');
            $collection->remove('delete');
        }
    }

* xml service registration

.. code-block:: xml

    <service id="acme.admin.route.entity" class="Acme\AdminBundle\Route\EntityRouterBuilder">
        <argument type="service" id="sonata.admin.audit.manager" />
    </service>


Inherited classes
-----------------

You can manage inherited classes by injecting subclasses using the service configuration.

Lets consider a base class named `Person` and its subclasses `Student` and `Teacher`:

.. code-block:: xml

    <services>
        <service id="sonata.admin.person" class="YourNS\AdminBundle\Admin\PersonAdmin">
            <tag name="sonata.admin" manager_type="orm" group="admin" label="Person"/>
            <argument/>
            <argument>YourNS\AdminBundle\Entity\Person</argument>
            <argument></argument>
            <call method="setSubClasses">
                <argument type="collection">
                    <argument key="student">YourNS\AdminBundle\Entity\Student</argument>
                    <argument key="teacher">YourNS\AdminBundle\Entity\Teacher</argument>
                </argument>
            </call>
        </service>
    </services>

You will just need to change the way forms are configured in order to take into account this new subclasses:

.. code-block:: php

    <?php
    // YourNS\AdminBundle\Admin\PersonAdmin.php
    
    protected function configureFormFields(FormMapper $form)
    {
        $subject = $this->getSubject();

        $form->add('name');

        if ($subject instanceof Teacher) {
            $form->add('course', 'text');
        }
        elseif ($subject instanceof Student) {
            $form->add('year', 'integer');
        }
    }
