Re: Read-only fields and complex relationships in admin

Thank you Jacob. That's actually the answer I was hoping for.

Yes: don't use the admin for this.

Really, I know it's tempting because the admin gives you like 50% of
what you want for free. But trust me when I tell you that if you go
down the path of trying to kludge the admin into supporting your
custom workflow you will be very unhappy. You'll get to 90% very
quickly, and then you'll spend a ridiculous amount of time trying to
close the final gap. You never quite will, and your app won't "feel"
right. Sooner or later you'll give up and write custom views from
scratch, throwing away all that hard work.

Really: I've seen this happen more times than I can count. Don't go
down this path.

Just write custom views. Try out some apps that reproduce certain
admin features -- apps like django-tables
(https://github.com/miracle2k/django-tables), django-filter
(https://github.com/alex/django-filter), django-pagination
(https://github.com/ericflo/django-pagination), and
django.contrib.formwizard or perhaps django-formwizard
(https://github.com/stephrdev/django-formwizard). They might save you
a bit of time, but you'll save the most time by not trying to force
the admin into doing something it's not good at.
