used the wrong email address to reply to the mailing list. Here again the Text:


have a look at the FreeNAS WebUI. They used Django ( ) together with DoJo ( ).

If we use this setup we get a lot of stuff already working:

On the Django site, as the backend:

- Abstraction on multiple layers. - There is no need to deal with the database backend. One defines types, and then uses them. Database layer is completely transparent.
- The main code that does everything is written as a module, that is then executed by Django for us. No need to write all the stuff around it.
- Views - every "module" also has views, which are used to generate the page shown to the user. It has a small language to be able to put the values in the right places.
- Every module that is written for Django, has it's own Types+Database, it's own main code and it's own views. It resides in it's own directory and does not interfere with any other plugin. Which breaks only the plugin and not the whole setup.
- It has it's own, builtin, webserver. It's not recommended for production use, but it's there ;) We could also run it as an FCGI backend connected to busybox' httpd.

With DoJo on the client side we get a fully working javascript framework that is know to work in Internet Explorer, Firefox, Chrome, Safari and Opera. We don't have to deal with anything on the client side. Only define the website, get the data in there and that's it. It also offers different GUIs for mobile devices like IPad, iPhone, Android, Windows Mobile and so on... So whatever we hit - it will work ;)

And it has a lot of nice plugins and views. Check out the website at

There is even a Djang-DoJo Distribution, but it hasn't been update for a longer time, so imho we should do it on our own.

We can provide a working environment that nearly fits all needs to any plugin developer which can make the Distro become popular for embedded devices and such :)

But there are also downsides:

- Django is written in Python... Maybe there is something similar written in Perl/Lua/Tcl/$Poison.
- The size of Python is really big imho and I don't know if it works with embedded Python.
- The javascript framework can produce a lot of load at the client if we do nasty things like on-the-fly search updates and stuff.

However, just a suggestion :)
