Using Django on Jython

Finally, Django works on Jython, without any special patching. Right now it is recommended to use the development version of both projects, but as soon as Django and Jython ship a new stable release, you will be able to use that too.

So, here are the steps to get Django on Jython running.

1. First, get a fresh version of Jython, and build it:

   • $ svn co https://jython.svn.sourceforge.net/svnroot/jython/trunk/jython/  jython-dev
     $ cd jython-dev
     $ ant

     This should create a dist/ directory inside jython-dev/. The jython "executable" (a shell script, actually) is under dist/bin. You may want to alias the command to avoid typing the whole path each time, with the command:

     $ alias jython25=/path/to/jython-dev/dist/bin/jython

     (or perhaps you prefer to add the directory to your PATH. Anyway, whatever works for you is OK)

2. Check out and install Django (Note: The Django 1.0 release should also work, if you don't want to follow trunk)

   • $ svn co http://code.djangoproject.com/svn/django/trunk/ django-dev
     $ cd django-dev
     $ jython25 setup.py install # Assuming you choose to use the "alias" trick explained on the previous point

     You may also like to make an alias for "django-admin.py". Very useful if you also use Django with CPython:

     $ alias django-admin-jy="jython25  /path/to/jython-dev/dist/bin/django-admin.py"

3. Check out and install django-jython:

   • $ svn co http://django-jython.googlecode.com/svn/trunk/ django-jython
     $ cd django-jython
     $ jython25 setup.py install

4. Start a project.

   • $ django-admin-jy startproject myproject

5. Edit myproject/settings.py and change the DATABASE_ENGINE to doj.backends.zxjdbc.postgresql.

At this point, you can follow the great Django documentation, remembering to use the jython25 command instead of python, and the JYTHONPATH variable instead of PYTHONPATH. Have fun!

Troubleshooting

Running the test suite on Windows

Seems like there is an issue with popen() on windows, which blocks the Django test suite. You can try skipping the offending test using these two patches (against Django 1.0.2), written by Victor Ng:
