validate method

@override Future<void> validate(EngineContext context, Map<String, String> rules, { bool bail = false, Map<String, String>? messages, })

Validates the request body against the given rules.

This method decodes the request body, creates a Validator with the provided rules, and validates the decoded body. If there are validation errors, a ValidationError is thrown.

context is the EngineContext of the request. rules is a Map of validation rules.

Returns a Future that completes when validation is done.

Implementation

@override
Future<void> validate(
  EngineContext context,
  Map<String, String> rules, {
  bool bail = false,
  Map<String, String>? messages,
}) async {
  final decoded = await _decodedBody(context); // Decode the request body.
  final registry = requireValidationRegistry(context.container);
  final validator = Validator.make(
    rules,
    registry: registry,
    bail: bail,
    messages: messages,
  ); // Create a validator with the rules.
  final errors = validator.validate(decoded); // Validate the decoded body.

  if (errors.isNotEmpty) {
    throw ValidationError(errors); // Throw an error if validation fails.
  }
}
