sorting field in py_dj

Edit admin.py to make these changes:

from django.contrib import admin
from mysite.books.models import Publisher, Author, Book

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

admin.site.register(Publisher)
admin.site.register(Author, AuthorAdmin)
admin.site.register(Book)



Here’s what we’ve done:

• We created the class AuthorAdmin. This class, which subclasses django.contrib.admin.ModelAdmin, holds custom configuration for a specific admin model. We’ve only specified one customization — list_display, which is set to a tuple of field names to display on the change list page. These field names must exist in the model, of course.

• We altered the admin.site.register() call to add AuthorAdmin after Author. You can read this as: “Register the Author model with the AuthorAdmin options.”

  The admin.site.register() function takes a ModelAdmin subclass as an optional second argument. If you don’t specify a second argument (as is the case for Publisher and Book), Django will use the default admin options for that model.
