The Django admin documentation generator

.. module:: django.contrib.admindocs
    :synopsis: Django's admin documentation generator.

.. currentmodule:: django.contrib.admindocs

Django's :mod:`~django.contrib.admindocs` app pulls documentation from the
docstrings of models, views, template tags, and template filters for any app in
:setting:`INSTALLED_APPS` and makes that documentation available from the
:mod:`Django admin <django.contrib.admin>`.

In addition to providing offline documentation for all template tags and
template filters that ship with Django, you may utilize admindocs to quickly
document your own code.


To activate the :mod:`~django.contrib.admindocs`, you will need to do
the following:

    * Add :mod:`django.contrib.admindocs` to your :setting:`INSTALLED_APPS`.
    * Add ``(r'^admin/doc/', include('django.contrib.admindocs.urls'))`` to
      your :data:`urlpatterns`. Make sure it's included *before* the
      ``r'^admin/'`` entry, so that requests to ``/admin/doc/`` don't get
      handled by the latter entry.
    * Install the docutils Python module (
    * **Optional:** Linking to templates requires the :setting:`ADMIN_FOR`
      setting to be configured.
    * **Optional:** Using the admindocs bookmarklets requires the
      :mod:`XViewMiddleware<django.middleware.doc>` to be installed.

Once those steps are complete, you can start browsing the documentation by
going to your admin interface and clicking the "Documentation" link in the
upper right of the page.

Documentation helpers

The following special markup can be used in your docstrings to easily create
hyperlinks to other components:

=================   =======================
Django Component    reStructuredText roles
=================   =======================
Models              ``:model:`appname.ModelName```
Views               ``:view:`appname.view_name```
Template tags       ``:tag:`tagname```
Template filters    ``:filter:`filtername```
Templates           ``:template:`path/to/template.html```
=================   =======================

Model reference

The **models** section of the ``admindocs`` page describes each model in the
system along with all the fields and methods available on it. Relationships to
other models appear as hyperlinks. Descriptions are pulled from ``help_text``
attributes on fields or from docstrings on model methods.

A model with useful documentation might look like this::

    class BlogEntry(models.Model):
        Stores a single blog entry, related to :model:`blog.Blog` and

        slug = models.SlugField(help_text="A short label, generally used in URLs.")
        author = models.ForeignKey(User)
        blog = models.ForeignKey(Blog)

        def publish(self):
            """Makes the blog entry live on the site."""

View reference

Each URL in your site has a separate entry in the ``admindocs`` page, and
clicking on a given URL will show you the corresponding view. Helpful things
you can document in your view function docstrings include:

    * A short description of what the view does.
    * The **context**, or a list of variables available in the view's template.
    * The name of the template or templates that are used for that view.

For example::

    from myapp.models import MyModel

    def my_view(request, slug):
        Display an individual :model:`myapp.MyModel`.



            An instance of :model:`myapp.MyModel`.



        return render_to_response('myapp/my_template.html', {
            'mymodel': MyModel.objects.get(slug=slug)
        }, context_instance=RequestContext(request))

Template tags and filters reference

The **tags** and **filters** ``admindocs`` sections describe all the tags and
filters that come with Django (in fact, the :ref:`built-in tag reference
<ref-templates-builtins-tags>` and :ref:`built-in filter reference
<ref-templates-builtins-filters>` documentation come directly from those
pages). Any tags or filters that you create or are added by a third-party app
will show up in these sections as well.

Template reference

While ``admindocs`` does not include a place to document templates by
themselves, if you use the ``:template:`path/to/template.html``` syntax in a
docstring the resulting page will verify the path of that template with
Django's :ref:`template loaders <template-loaders>`. This can be a handy way to
check if the specified template exists and to show where on the filesystem that
template is stored.

Included Bookmarklets

Several useful bookmarklets are available from the ``admindocs`` page:

    Documentation for this page
        Jumps you from any page to the documentation for the view that generates
        that page.

    Show object ID
        Shows the content-type and unique ID for pages that represent a single

    Edit this object
        Jumps to the admin page for pages that represent a single object.

Using these bookmarklets requires that you are either logged into the
:mod:`Django admin <django.contrib.admin>` as a
:class:`~django.contrib.auth.models.User` with
:attr:`~django.contrib.auth.models.User.is_staff` set to `True`, or
that the :mod:`django.middleware.doc` middleware and
:mod:`XViewMiddleware <django.middleware.doc>` are installed and you
are accessing the site from an IP address listed in :setting:`INTERNAL_IPS`.
