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 | sonata.admin.route.path_info_slashes
label_translator_strategy     sonata.admin.label.strategy.form_component
=========================     =============================================

Note: %manager-type% is to be replaced by the manager type (orm, doctrine_mongodb...),
and the default route_builder depends on it.

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

* With a tag attribute, less verbose:

.. configuration-block::

    .. 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>

.. configuration-block::

    .. code-block:: yaml

        acme.project.admin.project:
            class: Acme\ProjectBundle\Admin\ProjectAdmin
            tags:
                - 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"
            arguments:
                - ~
                - Acme\ProjectBundle\Entity\Project
                - ~

* With a method call, more verbose

.. configuration-block::

    .. 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>

.. configuration-block::

    .. code-block:: yaml

        acme.project.admin.project:
            class: Acme\ProjectBundle\Admin\ProjectAdmin
            tags:
                - { name: sonata.admin, manager_type: orm, group: "Project", label: "Project" }
            arguments:
                - ~
                - Acme\ProjectBundle\Entity\Project
                - ~
            calls:
                - [ setLabelTranslatorStrategy, [ @sonata.admin.label.strategy.native ]]
                - [ setRouteBuilder, [ @sonata.admin.route.path_info ]]

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

.. configuration-block::

    .. 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\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 disappear, delete functionality will be disabled as well
            // No more changes needed!
            $collection->remove('create');
            $collection->remove('delete');
        }
    }

* xml service registration

.. configuration-block::

    .. code-block:: xml

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

* YAML service registration

.. configuration-block::

    .. code-block:: yaml

        parameters:
            acme.admin.entity_route_builder.class: Acme\AdminBundle\Route\EntityRouterBuilder

        services:
            acme.admin.entity_route_builder:
                class: %acme.admin.entity_route_builder.class%
                arguments:
                    - @sonata.admin.audit.manager


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`:

.. configuration-block::

    .. 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');
        }
    }
