notnull = True is enforced at the level of the database and the field value cannot be None/NULL requires=is_not_empty() is enforced in forced in forms ate web2py level
required=True is completely different. It has nothing to do with the field value. It requires that a value always be specified in db.table.include(...) even if the field has a default or a computed attribute. It is a measure to prevent some programming errors. I never use it myself.
