    #set_fixture_class(class_names = {})  
  



  

    

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.
