I narrowed the problem to the fact that get_apps() from django.db.models
does not return the same list when called from mod_python or from the
integrated server. More precisely, it seems that for one of my
applications, in db/models/loading.py, the load_app() function checking
for 'models' attribute behaves differently according to the server used.
The hasattr(mod, 'models') call returns False for one of the
applications using mod_python, and True for the same application using the
integrated server. Thus, it's not listed in _app_list, and is not
displayed on the admin page.
I added an 'assert False, h', with h = hasattr(mod, 'models') in the
load_app() function from db/models/loading.py, and get the following with
mod_python:
assert False, h ...
▼ Local vars
Variable Value
app_name 'dNA.hostManage'
h False
mod <module 'dNA.hostManage' from '/var/www/dNA/hostManage/__init__.pyc'>
I removed *.pyc, and checked permissions on my folders and directories, but
they seems to be ok since I the hasattr(mod, 'models') works from the
shell:
>>> mod = __import__('hostManage', '', '', ['models'])
>>> mod
<module 'hostManage' from '/var/www/dNA/hostManage/__init__.pyc'>
>>> hasattr(mod, 'models')
True
After that, I'm truly lost, and I get no idea of what could be wrong. Did
anyone has any idea why the hasattr function could return different values
according to the server used?
