Django AdminPlus

AdminPlus aims to be the smallest possible extension to the excellent Django admin component that lets you add admin views that are not tied to models.

There are packages out there, like Nexus and django-admin-tools that replace the entire admin. Nexus supports adding completely new "modules" (the Django model admin is a default module) but there seems to be a lot of boiler plate code to do it. django-admin-tools does not, as far as I can tell, support adding custom pages.

All AdminPlus does is allow you to add simple custom views (well, they can be as complex as you like!) without mucking about with hijacking URLs, and providing links to them right in the admin index.

Installing AdminPlus

Grab AdminPlus from github with pip:

pip install -e git://github.com/jsocol/django-adminplus#egg=django-adminplus

And add adminplus to your installed apps:

INSTALLED_APPS = (
    # ...
    'adminplus',
    # ...
)

To use AdminPlus in your Django project, you'll need to replace django.contrib.admin.site, which is an instance of django.contrib.admin.sites.AdminSite. I recommend doing this in urls.py right before calling admin.autodiscover():

# urls.py
from django.contrib import admin
from adminplus import AdminSitePlus

admin.site = AdminSitePlus()
admin.autodiscover()

urlpatterns = patterns('',
    # ...
    # Include the admin URL conf as normal.
    (r'^admin', include(admin.site.urls)),
    # ...
)

Congratulations! You're now using AdminPlus.

Using AdminPlus

So now that you've installed AdminPlus, you'll want to use it. AdminPlus is 100% compatible with the built in admin module, so if you've been using that, you shouldn't have to change anything.

AdminPlus offers a new function, admin.site.register_view, to attach arbitrary views to the admin:

# someapp/admin.py
# Assuming you've replaced django.contrib.admin.site as above.
from django.contrib import admin

def my_view(request, *args, **kwargs):
    pass
admin.site.register_view('somepath', my_view)

# And of course, this still works:
from someapp.models import MyModel
admin.site.register(MyModel)

Now my_view will be accessible at admin/somepath and there will be a link to it in the Custom Views section of the admin index.

register_view takes a 3rd, optional argument: a friendly name for display in the list of custom views. For example:

def my_view(request):
    """Does something fancy!"""
admin.site.register_view('somepath', my_view, 'My Fancy Admin View!')

All registered views are wrapped in admin.site.admin_view.
