expect!(*filters) — ActionController::Parameters

expect!(*filters)

Same as expect, but raises an ActionController::ExpectedParameterMissing instead of ActionController::ParameterMissing. Unlike expect which will render a 400 response, expect! will raise an exception that is not handled. This is intended for debugging invalid params for an internal API where incorrectly formatted params would indicate a bug in a client library that should be fixed.

Parameters

filters rest
