A belongsTo relationship has the following possible schemas. For each schema, the child model can be in six states with respect to its parent:

 - the child can be saved and the parent can be one of: undefined, new or saved

 - the child can be new and the parent can be one of: undefined, new or saved

This is how the tests in this directory are organized.
