When using mod_python, it is possible to associate different parts of
the
URL namespace with different Python interpreter instances. Thus, you
should be able to run two different versions of Django under the one
web
server by hosting them under different URLs and then using the
directive
PythonInterpreter directive to separate them. For each instance, you
will
need to set the PythonPath directive to reference where the different
installations of Django are installed.
For example, something like:
<Location "/mysite1/">
PythonInterpreter django.mysite1
SetHandler python-program
PythonHandler django.core.handlers.modpython
SetEnv DJANGO_SETTINGS_MODULE mysite.settings
PythonDebug On
PythonPath "['/path/to/project','/path/to/django1'] + sys.path"
</Location>
<Location "/mysite2/">
PythonInterpreter django.mysite2
SetHandler python-program
PythonHandler django.core.handlers.modpython
SetEnv DJANGO_SETTINGS_MODULE mysite.settings
PythonDebug On
PythonPath "['/path/to/project','/path/to/django2'] + sys.path"
</Location>
Because they run in different Python interpreter instances, they
should not interfere with each other and doesn't matter that different
versions of same modules are used by each.
