validateEvent<Id, Data, T extends Service<Id, Data>> function

HookedServiceEventListener<Id, Data, T> validateEvent<Id, Data, T extends Service<Id, Data>>(Validator validator, { String errorMessage = 'Invalid data.', })

Validates the data in e.data, and sets the data to filtered data before continuing the service event.

Data that is not a Map, such as that of a read or remove, is a 400.

Implementation

HookedServiceEventListener<Id, Data, T> validateEvent<
  Id,
  Data,
  T extends Service<Id, Data>
>(Validator validator, {String errorMessage = 'Invalid data.'}) {
  return (HookedServiceEvent<Id, Data, T> e) async {
    var data = e.data;
    if (data is! Map) {
      throw AngelHttpException.badRequest(
        message: errorMessage,
        errors: ['The data must be an object.'],
      );
    }

    var app = e.request?.app ?? e.service.app;
    var result = await asyncApplyValidator(validator, data, app);

    if (result.errors.isNotEmpty) {
      throw AngelHttpException.badRequest(
        message: errorMessage,
        errors: result.errors,
      );
    }

    data
      ..clear()
      ..addAll(result.data);
  };
}
