Stuck in my PHP mindset when starting this project, I separated functionality of many views in two pieces: one view to display the data stored in the database, and another to make changes to the data.
Example:
dj3/forms/new_sub_request/$ (submission form for users to create a new request)
passes data via POST to
dj3/forms/process_sub_request/
and process_sub_request validates the input writes the new SubRequest object to the database.
However, after reading more, it seems to make more sense to just concat these two views into one, and switch between modes via GET variables ($process=1). At least, this is what I see most other projects doing.
