I'm try to implement object permission on django admin.

[Kidwind]

i'm override ModelAdmin for my object permission Backend like this

def has_delete_permission(self, request, obj=None):

opts = self.opts
return request.user.has_perm(opts.app_label + '.' + opts.get_delete_permission(), obj) # pass parm obj

but when i delete the obj,System back to me "Deleting the article 'test' would result in deleting related objects, but your account doesn't have permission to delete the following types of objects:article".
why? i try to find the Root of the problem.

in the django.contrib.admin.utils.get_deleted_objects not pass parm "obj" to detect the permission for related deleted obj.
Django did not provide extension points，I can only change the django source code.

when i try to implement object permission for django admin,What is the best solution，thank you.
