python - 如何在用户资源中插入 user_permissions 字段？

Question

我有以下用户资源代码，如何插入返回用户权限列表的'权限字段'？

class UserResource(ModelResource):
    user_permissions = fields.ToManyField #??????
    class Meta:
       queryset = User.objects.all()
       resource_name = 'user'
       authorization = Authorization()
       always_return_data = True
       list_allowed_methods = ['get', 'post', 'put', 'delete']
       authorization = DjangoAuthorization()
       authentication = MultiAuthentication(BasicAuthentication(), SessionAuthentication())
       filtering = {
           "date_joined": ALL,
           "email": ALL,
           "first_name": ALL,
           "is_active": ALL,
           "is_staff": ALL,
           "is_superuser": ALL,
           "last_login": ALL,
           "last_name": ALL,
           "username": ALL,
           "user_permissions": ALL_WITH_RELATIONS,
    }

如果你使用 django-tastypie 它可以像这样没有字段的情况下工作。

class UserResource(ModelResource):
     class Meta:
         # your definitions

     def dehydrate(self, bundle):
         # Include user permissions
         bundle.data['user_permissions'] = bundle.obj.user_permissions()
         return bundle
