How-to guides

Each guide answers one question a project meets, in the fewest steps that answer it. The tutorial builds a project from the start; these are for a project already under way.

guide	the question
Adopt it in an existing project	we use Django's permissions already - what changes?
Scope rows by a field of the person	each person sees their region's rows
An approval only some may give	only a manager approves, and never their own
Reference data everybody reads	everybody chooses a branch, few change one
A view that holds no model	a report, an export, an API root
Use an admin site of your own	our admin site has its own header and pages
Keep roles on the user model	our users have a role column already
Keep an audit trail	who gave whom what, and when
Check access in CI	the database and the ACCESS file must agree
Workers and websockets	a process that outlives a request
Test what people may do	a test per rule, not per view
