Is this the way to validate Django model fields?

Question

As I understand it, when one creates a Django application, data is validated by the form before it\'s inserted into a model instance which is then written to the database.

Answer 1

Capturing the pre-save signals on on my models ensured clean will be called automatically.

from django.db.models.signals import pre_save

def validate_model(sender, **kwargs):
    if 'raw' in kwargs and not kwargs['raw']:
        kwargs['instance'].full_clean()

pre_save.connect(validate_model, dispatch_uid='validate_models')
