Comment (by Fak3):
Regarding the proposed solution: Why not just add optional kwarg to
''is_valid'' method of ''ModelForm''? like this:
{{{
#!python
if form.is_valid(strict_uinique_checks=True):
obj = form.save()
}}}
The "''strict_uinique_checks''" kwarg will force ''ModelForm'' to perform
uinique_together checks using existing instance values if some.fields are
omitted in form.
Another option is to add new Meta option like this:
{{{
#!python
class MyForm(ModelForm):
class Meta:
strict_uinique_checks = True
}}}
Such form will then always fallback to using existing instance values for
uinique_together checks when performig validation.
