Serializer:

is_valid(self, raise_exception=False) # usually called before self.save(..)
- run_validation(self, data=empty)
  - validate_empty_values(self, data)
  - to_internal_value(self, data)
    - each DRF Field:
      - run_validation(self, data=empty)
        
        validate_empty_values(self, data)
        
        to_internal_value(self, data)
        
        run_validators(self, value)
      - validate_{field}(validated_value) # variable validate_method
  - run_validators(self, value) # Serializer Meta.validators (custom or derived from Model (Field) validators)
  - validate(self, attrs) # defined empty -- nice place to hook extra custom validation mechanisms via Mixins ?
