hasManyThrough<R extends KhademModel<R>> method

RelationDefinition<KhademModel> hasManyThrough<R extends KhademModel<R>>({ required String throughTable, required String throughForeignKey, required String relatedForeignKey, required String relatedTable, required R factory(), String? parentLocalKey, String throughLocalKey = 'id', dynamic query(QueryBuilderInterface)?, })

Define a "has many through" relationship with clearer parameter names.

See hasOneThroughVia for the key meanings; the mapping is identical, but this relation returns a list of related models.

Implementation

RelationDefinition hasManyThrough<R extends KhademModel<R>>({
  required String throughTable,
  required String throughForeignKey,
  required String relatedForeignKey,
  required String relatedTable,
  required R Function() factory,
  String? parentLocalKey,
  String throughLocalKey = 'id',
  Function(QueryBuilderInterface)? query,
}) {
  final resolvedParentLocalKey =
      parentLocalKey ?? (this as KhademModel).primaryKey;
  return RelationDefinition<R>(
    type: RelationType.hasManyThrough,
    localKey: resolvedParentLocalKey,
    foreignKey: '',
    relatedTable: relatedTable,
    factory: factory,
    throughTable: throughTable,
    firstKey: throughForeignKey,
    secondKey: relatedForeignKey,
    secondLocalKey: throughLocalKey,
    query: query,
  );
