List<KhademModel> matchOneOrMany(List<KhademModel> models, List<Related> results, String relation, String type,)

Match the eagerly loaded results to their parents.

Implementation

List<KhademModel> matchOneOrMany(
  List<KhademModel> models,
  List<Related> results,
  String relation,
  String type,
) {
  final dictionary = <dynamic, List<Related>>{};

  for (final result in results) {
    final key = result.getAttribute(foreignKey);
    if (key != null) {
      if (!dictionary.containsKey(key)) {
        dictionary[key] = [];
      }
      dictionary[key]!.add(result);
    }
  }

  for (final model in models) {
    final key = model.getAttribute(localKey);
    if (dictionary.containsKey(key)) {
      final value = dictionary[key]!;
      if (type == 'one') {
        model.setRelation(relation, value.isNotEmpty ? value.first : null);
      } else {
        model.setRelation(relation, value);
      }
    } else {

        model.setRelation(relation, null);
      } else {

      }
    }
