Overriding Default FOSUserBundle Templates
==========================================
As you start to incorporate FOSUserBundle into your application, you will probably
find that you need to override the default templates that are provided by
the bundle. Although the template names are not configurable, the Symfony
framework provides two ways to override the templates of a bundle.
1. Define a new template of the same name in the ``app/Resources`` directory
2. Create a new bundle that is defined as a child of ``FOSUserBundle``
Example: Overriding The Default layout.html.twig
------------------------------------------------
It is highly recommended that you override the ``Resources/views/layout.html.twig``
template so that the pages provided by the FOSUserBundle have a similar look and
feel to the rest of your application. An example of overriding this layout template
is demonstrated below using both of the overriding options listed above.
Here is the default ``layout.html.twig`` provided by the FOSUserBundle:
.. code-block:: html+jinja
{% for type, messages in app.session.flashBag.all %}
{% for message in messages %}
{{ message|trans({}, 'FOSUserBundle') }}
{% endfor %}
{% endfor %}
{% block fos_user_content %}
{% endblock fos_user_content %}
As you can see its pretty basic and doesn't really have much structure, so you will
want to replace it with a layout file that is appropriate for your application. The
main thing to note in this template is the block named ``fos_user_content``. This is
the block where the content from each of the different bundle's actions will be
displayed, so you must make sure to include this block in the layout file you will
use to override the default one.
The following Twig template file is an example of a layout file that might be used
to override the one provided by the bundle.
.. code-block:: html+jinja
{% extends 'layout.html.twig' %}
{% block title %}Demo Application{% endblock %}
{% block content %}
{% block fos_user_content %}{% endblock %}
{% endblock %}
This example extends the layout template from the layout of your app. The
``content`` block is where the main content of each page is rendered. This
is why the ``fos_user_content`` block has been placed inside of it. This
will lead to the desired effect of having the output from the FOSUserBundle
actions integrated into our applications layout, preserving the look and
feel of the application.
**a) Define New Template In app/Resources**
The easiest way to override a bundle's template is to simply place a new one in
your ``app/Resources`` folder. To override the layout template located at
``Resources/views/layout.html.twig`` in the ``FOSUserBundle`` directory, you would place
your new layout template at ``app/Resources/FOSUserBundle/views/layout.html.twig``.
As you can see the pattern for overriding templates in this way is to
create a folder with the name of the bundle class in the ``app/Resources`` directory.
Then add your new template to this folder, preserving the directory structure from the
original bundle.
**b) Create A Child Bundle And Override Template**
.. note::
This method is more complicated than the one outlined above. Unless you are
planning to override the controllers as well as the templates, it is recommended
that you use the other method.
As listed above, you can also create a bundle defined as child of FOSUserBundle
and place the new template in the same location that is resides in the FOSUserBundle.
The first thing you want to do is override the ``getParent`` method to your bundle
class.
.. code-block:: php
