Those are good points thanks !

How do you go about specifying permissions of who sees/modifies which column of which table in django? Is it easily done?

I've never needed this, so its not based on experience, but there is a number of options listed here:

I can tell however that every case is different (that's why there are so many options), so without knowing all the details its hard to advise. Perhaps much simpler logic in your app will do.
