#17018 new Bug

LayerMapping - entries skipped when ForeignKey field has related model missing and null = True

Reported by: Glen Robertson Owned by: nobody
Component: GIS Version: 1.3
Severity: Normal Keywords: geodjango, layermapping
Cc: Triage Stage: Accepted

Description

The LayerMapping utility will skip entries for a model that has missing foreign key entries when the foreign key field has null=True in it's configuration.
It would be better to add these entries and set the model's foreign key value to None when the foreign key doesn't exist.

Owner: changed from nobody to Aymeric Augustin

As above I have added attachments for an updated patch that includes unit tests.
They require the 3 files counties_null_state.* in the django/contrib/gis/tests/data/counties directory

I also modified the original patch to do the checking in the verify_fk method.

Cheers,
Glen
