Add support for prefetching fields This makes it possible to specify the fields that should be prefetched as part of a getForFields query. Doing a prefetch on a ReferenceProperty when it is known that the property will be referenced in (almost all) entities is far more efficient than doing the invididual fetches sequentially.

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)
