It's true: the Run model does not have a "lines" attribute; the RunHasSample model does. Also, `s1` is not a Line nor a Sample, it's an instance of the intermediary RunHasSample. So you're not going to be able to directly add a Line instance to a Run instance- you'll have to add it to the relevant RunHasSample instance instead.
