[Ironpython-users] Mono and Ironpython

[Dino Viehland]

One approach which might work, and could potentially be easier, would be starting with the Django 3.x branch and then update IronPython so it has the required 3.x features under the -X:Python30 command line option.  I'm just thinking it might be easier in a world where Django was getting Unicode strings when it expected to.

Thanks for the inputs Vernon, Jeff.

Just checked Jeff's old posts and bitbucket page, it does not look pretty, at least with my
current time constraints.

The only thing that I absolutely can not avoid using is the .NET library , so I can get away with
using cherrypy/ironpython as middle tier between clients and my existing Django application. Its a low load
application.

If nothing works, eventually I can try mono-fastcgi, and write this part in C#, but thats last resort, everything
else is in python.

Getting ironpython-django working will be cool though. I will try it out outside the scope of current project.

I did work on it a bit a few years ago, and there's some out-of-date
patches at https://bitbucket.org/jdhardy/django-ipy-patches.

This was before IronPython was taking contributions, so getting fixes
into IP was much harder. If anybody is interested in it, and is aware
that there's a massive amount of work involved, you'd have my full
support, and any fixes would be greatly appreciated.
