Constructor Details

#initialize(params, supplied_params = nil) ⇒ Me

supplied_params are the params that were actually passed in by the user. In Rails, params has some additional keys (e.g. controller, action), so you can pass in request.query_parameters (GET) and/or request.request_parameters (POST) for supplied_params to correctly get only the user-supplied parameters.
