The Django admin documentation generator

Django’s admindocs app pulls documentation from the docstrings of models, views, template tags, and template filters for any app in INSTALLED_APPS and makes that documentation available from the Django admin.

概况

To activate the admindocs, you will need to do the following:

  • Add django.contrib.admindocs to your INSTALLED_APPS.
  • Add path('admin/doc/', include('django.contrib.admindocs.urls')) to your urlpatterns. Make sure it’s included before the 'admin/' entry, so that requests to /admin/doc/ don’t get handled by the latter entry.
  • Install the docutils Python module (http://docutils.sf.net/).
  • Optional: Using the admindocs bookmarklets requires django.contrib.admindocs.middleware.XViewMiddleware 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
模型 :model:`app_label.ModelName`
视图 :view:`app_label.view_name`
模板标签 :tag:`tagname`
模板过滤器 :filter:`filtername`
模板 :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, properties, 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.

Changed in Django 2.2:

Older versions don’t display model properties.

A model with useful documentation might look like this:

class BlogEntry(models.Model):
    """
    Stores a single blog entry, related to :model:`blog.Blog` and
    :model:`auth.User`.
    """
    slug = models.SlugField(help_text="A short label, generally used in URLs.")
    author = models.ForeignKey(
        User,
        models.SET_NULL,
        blank=True, null=True,
    )
    blog = models.ForeignKey(Blog, models.CASCADE)
    ...

    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.

例子:

from django.shortcuts import render

from myapp.models import MyModel

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

    **Context**

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

    **Template:**

    :template:`myapp/my_template.html`
    """
    context = {'mymodel': MyModel.objects.get(slug=slug)}
    return render(request, 'myapp/my_template.html', context)

Template tags and filters reference

The tags and filters admindocs sections describe all the tags and filters that come with Django (in fact, the built-in tag reference and built-in filter reference 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 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

One bookmarklet is available from the admindocs page:

关于本页面的文档
从任何页面跳转到生成该页面的 view 文档。

Using this bookmarklet requires that XViewMiddleware is installed and that you are logged into the Django admin as a User with is_staff set to True.
