Using eggs with mod_python
==========================
If you installed Django from a Python egg_ or are using eggs in your Django
project, some extra configuration is required. Create an extra file in your
project (or somewhere else) that contains something like the following::
import os
os.environ['PYTHON_EGG_CACHE'] = '/some/directory'
Here, ``/some/directory`` is a directory that the Apache webserver process can
write to. It will be used as the location for any unpacking of code the eggs
need to do.
Then you have to tell mod_python to import this file before doing anything
else. This is done using the PythonImport_ directive to mod_python. You need
to ensure that you have specified the ``PythonInterpreter`` directive to
mod_python as described above__ (you need to do this even if you aren't
serving multiple installations in this case). Then add the ``PythonImport``
line inside the ``Location`` or ``VirtualHost`` section. For example::
PythonInterpreter my_django
PythonImport /path/to/my/project/file.py my_django
Note that you can use an absolute path here (or a normal dotted import path),
as described in the `mod_python manual`_. We use an absolute path in the
above example because if any Python path modifications are required to access
your project, they will not have been done at the time the ``PythonImport``
line is processed.
