如何使用自定义 AdminSite 类?

I fixed this with a litte hack. I wrote this class:

from django.contrib.admin.sites import site as default_site

class AdminSiteRegistryFix( object ):
    '''
    This fix links the '_registry' property to the orginal AdminSites
    '_registry' property. This is necessary, because of the character of
    the admins 'autodiscover' function. Otherwise the admin site will say,
    that you havn't permission to edit anything.
    '''

    def _registry_getter(self):
        return default_site._registry

    def _registry_setter(self,value):
        default_site._registry = value

    _registry = property(_registry_getter, _registry_setter)

并像这样实现我的自定义 AdminSite:

from wltrweb.hacks.django.admin import AdminSiteRegistryFix
from django.contrib.admin import AdminSite

class MyAdminSite( AdminSite, AdminSiteRegistryFix ):
    # do some magic
    pass        


site = MyAdminSite()
