The following can be used as a base when you want to avoid the normal structure Django imposes on your project, and you just want everything in a single file.
It is based on similar attempts by Ivan Sagalaev and Fahrzin Hemmati (especially this gist), and a post on stack overflow.
A thing that I consider an improvement over Fahrzin Hemmati's version is that models don't need the explicit app_label and __module__.
