Hi folks --
I'm having a problem with admin inlines on a particular model suddenly
not showing up, even though they were working previously. Oddly,
they're working just fine on the exact same code in staging (granted,
on a somewhat different server setup) but not in production.
The only changes I've made between versions are to wrap any help text
for each model field in ugettext_lazy.
I've googled, and the only suggestion I've found is that the
__unicode__ methods of the models might be throwing errors -- I tested
them on the command line, on those specific objects, and everything
was fine.
Below are the (simplified) models and admins. Since I can't reproduce
the problem in staging, can anyone suggest where to start in terms of
tracking down what's going wrong without disrupting production?
Thanks!
Nan
