Description (last modified by Russell Keith-Magee)

I'm not sure if this is a documentation bug, or a code bug, or operator headspace error.

I have a model where a column needs to be unique in a case insensitive fashion, but should be stored in a case sensitive fashion.
I have applied custom SQL for that constraint.

As I am bulk loading the table, I am making use of get_or_create(field0__iexact=value0, field1=value1).
When I use this invocation, field0 ends up being set as null.

If I invoke it as get_or_create(field0__iexact=value0, field0=value0, ...)
I eventually have a constraint error.

I would expect a FieldError if field0__iexact were not permitted, and I would expect the fieldname to be calculated from field0__iexact if it were permitted.

I am currently avoiding the problem by catching an exception on psycopg2.IntegrityError, but that does not seem to be the right solution.

Sounds like you've missed the section on defaults in the docs.

For future reference, if you're uncertain if you've found a bug, it's better to ask on django-users first.
