Django: "projects" vs "apps"

python django namespaces project-organization

I have a fairly complex "product" I'm getting ready to build using Django. I'm going to avoid using the terms "project" and "application" in this context, because I'm not clear on their specific meaning in Django.

Projects can have many apps. Apps can be shared among many projects. Fine.

I'm not reinventing the blog or forum - I don't see any portion of my product being reusable in any context. Intuitively, I would call this one "application." Do I then do all my work in a single "app" folder?

If so... in terms of Django's project.app namespace, my inclination is to use myproduct.myproduct, but of course this isn't allowed (but the application I'm building is my project, and my project is an application!). I'm therefore lead to believe that perhaps I'm supposed to approach Django by building one app per "significant" model, but I don't know where to draw the boundaries in my schema to separate it into apps - I have a lot of models with relatively complex relationships.

I'm hoping there's a common solution to this...

Once you graduate from using startproject and startapp, there's nothing to stop you from combining a "project" and "app" in the same Python package. A project is really nothing more than a settings module, and an app is really nothing more than a models module—everything else is optional.

For small sites, it's entirely reasonable to have something like:

site/
    models.py
    settings.py
    tests.py
    urls.py
    views.py
