ParamValidationMixin
public_api/rest_generics/controllers.py
- uses flask.request.view_args: http:/x.com/project/<pid>
- derived from flask.MethodView, so REST methods are generated automatically
- http://flask.pocoo.org/docs/0.12/views/#method-based-dispatching
- values are accessible through dict named self.params
- ParamValidationMixin.param_validator_class
