Description (last modified by Karen Tracey)

Seems that model forms or admin dones't clean correctly inline forms.

class Child(models.Model):
   parent = models.ForeignKey(Parent)
   something = models.CharField(blank=True, null=True, unique=True)

   def clean(self):
       if self.something == '':
           self.something = None
       super(Child, self).clean()

Postgres raises a: duplicate key value violates unique constraint "child_something_key"

I've made a little hack on django's code and call child.clean() just before, and then it works. Also I've tried a similar scenario with an admin.ModelAdmin instead of admin.TabularInline and it works to. So it must be a bug somewhere on the inlines.

Node: I'm using master, not tested with 1.4

Could you provide a complete example of parent/child models plus the admin classes you are using? It's going to require a bit of guesswork to try to replicate the error you describe with just a single model definition and no guidance on how you have set up the admin defs.
