Hmm... After a little testing, this is not what I wanted, some of the model1 objects in the return_list was not in the provided modelList, and I dont't quite understand why they are returned. As stated before, I want to get a distinct list of all model1 objects that is in a provided list and is used as a foreignkey in any model2 object. Is this doable?
