class Account(models.Model):
    provider = models.ForeignKey(Provider, verbose_name = 'Provider')
    percent = models.PositiveSmallIntegerField(u'Percent', null = True, blank = True)
    
    aid = models.PositiveIntegerField(u'Affiliate ID')
    skey = models.CharField(u'Secret key', maxlength = 256, blank = True)
    
    class Meta:
        unique_together = (('provider', 'aid'),)

You're right, they don't automatically validate against unique_together currently.

Whether they should or not is up for debate.

This gets fixed once Jacob has finished the model-aware validation stuff we started working on at OSCON. Things like this must be validated in the model, not the form, but for the form_for_* cases, the model's errors should then be fed back to the form. So the problem is real, but we are fixing it in a more holistic fashion than just tweaking form_for_*.

Marked #5736 as a duplicate. unique and unique_together will be fixed with some model aware validation that Malcolm mentions above.

What is the ETA on the "model aware validation" changes? (I am trying to decide how much effort to spend working around this bug)

Any progress on this? I'm still getting this exception when UNIQUE is violated.

form_for_* are now deprecated and replaced by ModelForm? so the bug should be tested with it I guess.

01/05/08 13:22:26 changed by ipse <ipse.reg@gmail.com>

It is still here with ModelForms? (I'm using them, not form_for_*).

also missing field's unique=True support.

See http://www.djangosnippets.org/snippets/649/ for a workaround that can be used until model validation gets integrated.
