.. _controller-access-services-directly:

Accessing the Container Directly
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

If you extend the base ``Controller`` class, you can access :ref:`public services <container-public>`
via the :method:`Symfony\\Bundle\\FrameworkBundle\\Controller\\Controller::get`
method. Here are several common services you might need::

$templating = $this->get('templating');

$router = $this->get('router');

$mailer = $this->get('mailer');

// you can also fetch parameters
$someParameter = $this->getParameter('some_parameter');

If you receive an error like:

.. code-block:: text

You have requested a non-existent service "my_service_id"

Check to make sure the service exists (use :ref:`debug:container <container-debug-container>`)
and that it's :ref:`public <container-public>`.
