Month summary — February 2022

I watched a very nice talk about structuring a Django application (Radoslav Georgiev - Django structure for scale and longevity) and analyzed the repository complementary to that talk (Django Styleguide). TLDR/TLDW: the whole idea behind it is that all business logic should NOT live in:

• APIs and Views.
• Serializers and Forms.
• Form tags.
• Model save method.
• Custom managers or querysets.
• Signals

but in:

• Services - functions that mostly take care of writing things to the database.
• Selectors - functions that mostly take care of fetching things from the database.
• Model properties (with some exceptions).
• Model clean method for additional validations (with some exceptions).

This seems to be a pretty awesome idea. Often, the business logic is spread across Django in views or serializers and with a growing project it is easy to fall into some redundancy here and there. Afterwards, with updates and further growth it is getting harder to keep track of where scattered logic parts live. The proposed structure helps to keep all crucial logic in an intuitive place (like service) and reuse it in views, serializers etc. This Django Styleguide speaks to me since I had the pleasure to work on a project which was written in Flask but also facilitated services. For more details watch the talk and check the repo.

Other highlights of the month: I made some improvements to my GitHub Action TobKed/github-forks-sync-action. In addition to bug fixes I put together an example of syncing multiple branches. It emerged from the discussion on the issue.
