Chapter 6 Admin Panel

The django.contrib packages

CONFIGURATION for admin app
First, make a few changes to your settings file:
  1. Add 'django.contrib.admin' to the INSTALLED_APPS setting. (The order of INSTALLED_APPS doesn’t matter, but we like to keep things alphabetical so it’s easy for a human to read.)
  2. Make sure INSTALLED_APPS contains 'django.contrib.auth''django.contrib.contenttypes' and 'django.contrib.sessions'. The Django admin site requires these three packages. (If you’re following along with our ongoing mysite project, note that we commented out these three INSTALLED_APPS  entries in Chapter 5. Uncomment them now.)
  3. Make sure MIDDLEWARE_CLASSES contains 'django.middleware.common.CommonMiddleware','django.contrib.sessions.middleware.SessionMiddleware' and 'django.contrib.auth.middleware.AuthenticationMiddleware'. (Again, if you’re following along, note that we commented them out in Chapter 5, so uncomment them.)

Put 'django.contrib.admin' in your INSTALLED_APPS setting in order to use the admin application.s

 run python syncdb

# Include these import statements...
from django.contrib import admin

# And include this URLpattern...
urlpatterns = patterns('',
    # ...
    (r'^admin/', include(,
    # ...

Adding Your Models to the Admin Site

Within the books directory (mysite/books) App Directory
from django.contrib import admin
from mysite.books.models import Publisher, Author, Book

(need restart the server)
Beyond that, the Django admin site is just a Django application, with its own models, templates, views and URLpatterns.

    list_display = ('first_name', 'last_name', 'email'), AuthorAdmin)

class AuthorAdmin(admin.ModelAdmin):
    list_display = ('first_name', 'last_name', 'email')
    search_fields = ('first_name', 'last_name')

Select author to change

class BookAdmin(admin.ModelAdmin):
    list_display = ('title', 'publisher', 'publication_date')
    list_filter = ('publication_date',)
