Partially use the new user code
The 'edit self' is not working fully yet, the 'lookup' code is not
working at all, as such, only 'create', 'edit', 'list', and 'delete'
make use of the generic code.
from django.contrib import admin
from django.contrib.sites.models import Site
class SiteAdmin(admin.ModelAdmin):
list_display = ('domain', 'name')
search_fields = ('domain', 'name')
admin.site.register(Site, SiteAdmin)
