Replying to [comment:4 Simon Charette]:

`GenericTabularInline`'s form is passing an `exclude` of either
`{'user','content_type', 'object_id'}` the following statement confused me
though

constraint violation?

> Can you also reproduce the same issue by using `unique_together` instead
of `UniqueConstraint(fields=['user','content_type', 'object_id'],
name='unique_object')`. If you can then I'm not convinced this should be
considered a release blocker.
It is not crashing, the object is created successfully and I get the green
success message I can even go to the Skill_level admin page and see the
duplicate objects. Opening one of the objects and saving without any
changes gives the usual Uniqueconstraints error message.
