When I tried that I kept running into this error: "Cannot set values on a ManyToManyField which specifies an intermediary model. Use foo.FilmRole's Manager instead." ... which led me down a different path but perhaps I should have persevered more. I have googled this error extensively and spent some time digging into Django internals to figure out what is happening. Basically I can see that if Django didn't auto-generate the relationship manager class then it will throw this error. Conceptually I totally get why that is (it has no way of knowing what values to assign to the extra fields). What I don't get is how I'm supposed to get around it. Lets say I wanted to put some code somewhere to munge the missing fields to some default value. Where would I put that code? I can't relate to the error message at all. I read about manager classes and how I can override query sets and so on. Sure that totally makes sense. But how does that help me here? How can I use the manager for FilmRole? Do I need to override some method in my manager? Which method? An example would be really useful here.
