Make a Django model read-only?
What it says on the tin. Is there a way to make a Django model read-only?
By this I mean a Django model in which once records have been created, they can't be edited.
This would be useful for a model that records transaction history.
You can override the model's save method and check whether it's an existing entity, in which case you won't save any changes:
def save(self, *args, **kwargs): if self.id is None: super(ModelName, self).save(*args, **kwargs)
So in this example you only save the changes when the entity has not got an id yet, which is only the case when it's a new entity that hasn't been inserted yet.
