matchMorphMany method

List<Map<String, dynamic>> matchMorphMany(List<Map<String, dynamic>> models, List<Map<String, dynamic>> results, String relation, String parentKey, String relatedIdKey, String typeKey, String expectedType,)

Match many related morph models to parents. Only includes results where the morph type (at column typeKey) equals expectedType.

Implementation

List<Map<String, dynamic>> matchMorphMany(
  List<Map<String, dynamic>> models,
  List<Map<String, dynamic>> results,
  String relation,
  String parentKey,
  String relatedIdKey,
  String typeKey,
  String expectedType,
) {
  Map<String, List<Map<String, dynamic>>> dictionary = {};
  final type = expectedType.toLowerCase();
  for (var result in results) {
    if (result[typeKey]?.toString().toLowerCase() == type) {
      String key = result[relatedIdKey].toString();
      if (!dictionary.containsKey(key)) {
        dictionary[key] = [];
      }
      dictionary[key]!.add(result);
    }
  }

  models = models.map((model) {
    String key = model[parentKey].toString();
    Map<String, dynamic> cloneModel = Map.from(model);
    if (dictionary.containsKey(key)) {
      cloneModel[relation] = dictionary[key];
    } else {
      cloneModel[relation] = <Map<String, dynamic>>[];
    }
    return cloneModel;
  }).toList();

  return models;
}
