Re: calling self.clean() before super.save()

I believe ModelForm calls your model's self.clean so if you use it, or use the admin which uses it, you'll need to make sure that clean is idempotent since it'll get called at least twice in that case.

Until now I have been calling clean() deliberately prior to calling 
save() but I have a lot of models where save() pre-processes data just 
prior to calling the model's super().save(*args, **kwargs)

I feel as though it would more robust to pre-process the data, then call 
self.clean() and finally make the super call.

Thanks for any advice.
