set_fixture_class(class_names = {}) click to toggle source

Sets the model class for a fixture when the class name cannot be inferred from the fixture name.

Examples:

    set_fixture_class some_fixture:        SomeModel,
                      'namespaced/fixture' => Another::Model

The keys must be the fixture names, that coincide with the short paths to the fixture files.

      self.fixture_class_names = self.fixture_class_names.merge(class_names.stringify_keys)
