In case the problem lies in manipulating the python path inside a
<Location> section, perhaps you could play another trick to load the
different versions of django. I am doing as follows, though, not with
Location tags but in VirtualHost sections, and it works for me:
Somewhere on the python path, there is a subdirectory,
django_versions. In there, several django trees exist. On the same
level as django_versions subdirectory i have wrapper modules, one for
each django version i need, named django_trunk.py, django_096.py, and
so on. The wrapper code reads:
##
import imp, os
django = imp.load_module(
"django",
*imp.find_module("django", [os.path.join(
os.path.dirname(__file__), "django_versions", "django-
trunk"
)] )
)
del imp, os
all together, the layout is:
/python-path/django_trunk.py
/python-path/django_someversion.py
/python-path/django_vresions/
/python-path/django_versions/django-trunk/django
/python-path/django_vresions/django-someversion/django
Note, there is no need to have an __init__.py inside django_versions,
since the path munging is done in the wrapper module, where the
required django module is loaded from a temporary fixed path set up
dynamically.
To use this, a second wrapper file is needed for the mod_python
handler. This one is named django_trunk_handler.py and should be put
somewhere on your python path as well:
import django_trunk as django
from django.core.handlers.modpython import handler
And analogous to that, you can have django_someversion_handler.py:
import django_someversion as django
from django.core.handlers.modpython import handler
Now, in httpd.conf, this comes together:
<Location /version1>
...
PythonHandler django_trunk_handler
PythonInterpreter version1
</Location>
<Location /version2>
...
PythonHandler django_someversion_handler
PythonInterpreter version2
</Location>
Finally, you might want to have different manage.py stubs with an
extra first line importing the right django module as django into the
namespace to get going.
Best regards...
