If you inherit from ValidatedModel instead of from models.Model, then full_clean() will be called before save().

So, add validators to your field definitions, and all your fields will be validated before they go to the database.

The same thing can be accomplished with a pre_save signal, but the code is quite a bit messier than the simple inheritance above.

class ValidatedModel(models.Model):
    def save(self, *args, **kwargs):
        self.full_clean()
        super(ValidatedModel, self).save(*args, **kwargs)

    class Meta:
        abstract = True
