@ -365,6 +365,16 @@ translates (roughly) into the following SQL::
.. _`Keyword Arguments`: http://docs.python.org/tutorial/controlflow.html#keyword-arguments
.. versionchanged:: 1.4
The field specified in a lookup has to be the name of a model field.
There's one exception though, in case of a
:class:`~django.db.models.fields.ForeignKey` you can specify the field
name suffixed with ``_id``. In this case, the value parameter is expected
to contain the raw value of the foreign model's primary key. For example::
>>> Entry.objects.filter(blog_id__exact=4)
If you pass an invalid keyword argument, a lookup function will raise
``TypeError``.
