Is this the way to validate Django model fields?

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. But if I want to create an additional layer of protection at the data model layer, is what I’ve done below the current “best practice?” I’m trying to ensure that a reviewer’s name cannot be omitted nor be left blank. Should I be putting any custom validation in the ‘clean’ method as I’ve done here and then have ‘save’ call ‘full_clean” which calls ‘clean’? If not, what’s the preferred method? Thanks.
