class GenericRelation(ForeignObject): (source)

View In Hierarchy

Provide a reverse to a relation created by a GenericForeignKey.

Method __init__ Undocumented
Method bulk_related_objects Return all objects related to ``objs`` via this ``GenericRelation``.
Method check Undocumented
Method contribute_to_class Undocumented
Method get_content_type Return the content type associated with this field's model.
Method get_extra_restriction Undocumented
Method get_internal_type Undocumented
Method get_path_info Undocumented
Method get_reverse_path_info Undocumented
Method resolve_related_fields Undocumented
Method set_attributes_from_rel Undocumented

Instance Variable content_type_field_name Undocumented

Instance Variable object_id_field_name Undocumented
Instance Variable to_fields Undocumented
Method _check_generic_foreign_key_existence Undocumented
Method _get_path_info_with_parent Return the path that joins the current model through any parent models. The idea is that if you have a GFK defined on a parent model then we need to join the parent model first, then the child model.
Method _is_matching_generic_foreign_key Return True if field is a GenericForeignKey whose content type and object id fields correspond to the equivalent attributes on this GenericRelation.
