6773	Confusing error when ForeignKey lookup fails while serializing	Kenneth Arnold		"I got a confusing error when running {{{manage.py dumpdata}}}:

{{{
Error: Unable to serialize database:
}}}

Turns out that a {{{ForeignKey}}} had been marked {{{blank=True}}} but not {{{null=True}}}.

The error message gave no hint as to even which model to look in; the real exception lay hidden behind two levels of error handlers. Maybe serializers should pass on exceptions?"
