How the DataRobot mixins work

validation_notes.txt

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

QueryValidationMixin
public_api/rest_generics/filters.py
- works on query args: http:/x.com/path/?project=deadbeefdeadbeef
- provides no REST-named methods
- main interface is through get_query_params() which provides a dict of arguments (including flask.request.args)
- QueryValidationMixin.query_validator_class

PayloadValidationMixin
public_api/rest_generics/controllers.py
- REST-named methods: post, put, patch, delete
- uses flask.request.data
- PayloadValidationMixin.validator_class
- values are accessible through dict named validator.data in the scope of validator_valid
