Hey all,
I have a model with some fairly strict rules on what is or isn't allowed
and I'd like to perform some validation. The model is created via various
forms, other functions, and via api calls and so validating the data before
the model is created would be quite complicated. Reading on Stack Overflow,
people seem to caution against overriding the Model.save() function to call
a clean function which checks for these issues. However all the posts I've
seen on it were from Django 1.2 or 1.3 and I'm not certain if they're still
relevant. So Is there a reason not to do it this way? If so, what would a
good solution be.
Example Code:
class MyModel:
def save(self, *args, **kwargs):
"""
Override the save function to provide some validation on the model.
"""
self.clean()
super(MyModel, self).save(*args, **kwargs)
def clean(self):
if badThing == True:
raise ValidationError("This data is bad and you should feel bad"
)
