+to reference an object. and while delete the object, it will raise exception.
+While I used field names `item_type`, `item_id` instead of `content_type`, `object_id` to reference an object. and while delete the object, it will raise exception.
 For example:
+{{{
+#!python
 class ObjectPermission(models.Model):
     # implement object/row based permission
 …
 class Publisher(models.Model):
     name = models.CharField(max_length=255)
+}}}
 I create an relation between publisher and object permission.
 while delete a publisher in django admin, it will raise fielderror,
+{{{
 at query.py line 1320
 raise FieldError("Cannot resolve keyword object into field. "
                             "Choices are: %s" % (name, ", ".join(names)))
+}}}
 and after I change the field name back to content_type, object_id,
 the exception won't appear.
