Thank you very much for your detailed answer @wolf4earth! It is a good starting point for me and I will definitely attempt it.
Do you think it will be ok to make associations between models as needed, even though they live in different umbrella apps? For example, the “main” app will have a user model, and a “sub app” a blog post model. These have to be associated with one another (user is author of a post).
Also, why is this not a frequently asked question? Do other people just write their apps from scratch?
