What's this?

expect!(*filters) public

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.
