Generate class diagram from django models

[jarlhengstmengel]

Motivation

We quite often run into the problem of losing the overview over our data structure. It can be quite time consuming figuring out the relations between different models, which are inheriting variables from others or what data is realized as cached properties.

Proposed Solution

Export django models as class diagram. This could be a possible starting point for realizing this.

Alternatives

Continue individually trying to get an overview for isolated parts when needed.

I use dbeaver-ce for thinks like this. It has a decent GUI to examine database connections. This is what an ER-diagram of our complete postgres looks like:

Of course, it is possible to break it down further, and you can examine links between models better in the tool

Ideally we would choose an option where this diagram is updated automatically and this could be part of the docu-building jobs or of the CI/CD pipeline
