Hi everyone,
Given a field in a model that uses choices:

CHOICES =(
  (0,"choice_0"),
  (1,"choice_1")
)
foo =models.IntegerField(choices=CHOICES)
|
If i put a value other than 0 or 1, django will accept it. Is that
possible that we instruct Django to accept only values that are
mentioned in CHOICES without creating a validator function.
Why don't you want to validate in the model?
I find it valuable to put all sorts of validators in the clean() method
and raise a ValidationError to force the user to enter good data. eg.,
if self.foo not in CHOICES:
raise ValidationError("bad foo")
Unless there are special reasons otherwise, I think it is much better in
the model than the form.
