"Foo bar with this None and None already exists."
Try to save a combination of foo and bar that already exists using the
form below and the
error message says "this None and None", comment out the field
overrides and there's no problem.
Not sure whether the problem is with unique_together or ModelForm.
Models
{{{
class Foo(models.Model):
f = models.IntegerField(unique=True)
def __unicode__(self):
return 'Foo with f = %d' % self.f
class Bar(models.Model):
b = models.IntegerField(unique=True)
def __unicode__(self):
return 'Bar with b = %d' % self.b
class FooBar(models.Model):
foo = models.ForeignKey('Foo')
bar = models.ForeignKey('Bar')
class Meta:
unique_together = (('foo','bar'),)
}}}
Form
{{{
class FooBarForm(forms.ModelForm):
foo = forms.ModelChoiceField(Foo.objects.all()) # comment this line
out an the error message is correct
bar = forms.ModelChoiceField(Bar.objects.all()) # comment this line
out an the error message is correct
class Meta:
model = FooBar
}}}
