Hello,
Just wondering how to create groups automatically in Django and
automatically assign permissions?
Sounds easy. I have created a database migration to do just this.
The problem is under Django the permissions are not created until
after all the migrations are finished. So the resultant migration
works fine on my development box, but fails badly on new installs,
including tests.
Can you separate the process into separate migrations? Each can have a
dependency on the one prior.
Looking at slashdot, I see questions like
https://stackoverflow.com/questions/42743825/how-to-create-groups-and-assign-permission-during-project-setup-in-django which
recommend setting up a post_migrate signal handler. Unfortunately,
signal handlers in Django are unordered, there is no guarantee our
handler will be called after the one that creates the permissions.
I could also have some sort of button in Django Admin that needs to be
manually pressed - would happen after permissions are created. Seems
to me though that doing significant changes to the database group
table from a HTTP request may not be ideal...
Any other suggestions? I am somewhat surprised that this situation
doesn't seem to have any good answers.
