Re: wordpress hooks and actions system in django?
I thought I would chime in here as well, having a good deal of code written for WordPress, and now some experience with Django. I had originally contemplated the same idea, create a plugin system like that of WP until I started to understand the power of applications. In my mind it would be a terrible amount of work to create a system to read a plugin's structure, handle permissions (if needed) and then be compatible with the template system, when it's very simple to create an app to do something pluggable (say a classifieds application). The ease with which you can build new features in django, and make them available to other projects far outweighs any advantage I can think with some kind of plugin system (just my opinion). I try to write the applications for my project as if they needed to be pluggable, as few dependancies as possible, etc. And as far as wp filters go, the signal system should be more than capable. Do your need to provide the ability for another person to write 'plugins' or functionality for django? I'm thinking maybe there is something you know how to do well in wordpress but aren't sure how it's done/available in django?

Re: wordpress hooks and actions system in django?
I had an idea about this, I would just like to say it is porbably un- pythonic, scary, and completely untested, here goes: Create a model for plugins, it should have a filefield and a few other fields for meta data(these should not be editable), plus a boolean field for enabled. Essentially what should happen is the file will contain a class and some meta data that gives information about itself. When you upload the file it gets read to get the meta data out(for example it might have a title, description, author, and some way of telling your application what it expects for input). This can be done using the __import__ feautre of python, here is an example: http://dpaste.com/36440/ in the .py file there should be a variable with a generic name that is a copy of the class, that way the class can be whatever you want, then each plugin's class just needs to implement a generic interface, and a inner class with the meta info, then when you want to use it you could do something like this: http://dpaste.com/36442/ On Feb 22, 11:18 am, canen <[EMAIL PROTECTED]> wrote: > Just chiming in here.

Re: wordpress hooks and actions system in django?
Just chiming in here. There is a Wordpress 'clone' written in Python called Textpress [1]. It implements a lightweight events/actions system[2] akin to the one you mentioned.

Re: wordpress hooks and actions system in django?
The part that I'm struggling to wrap my head around is how to make plugins "installable". I think one of the reasons Wordpress's plugin framework is so successful is how easy it is to manage your plugins: install / uninstall buttons on a page means the user doesn't have to write any glue code or even do anything from the command line. I guess you could have an empty 'plugins' app somewhere, and simply drop py files into it for each plugin. What are your guys' thoughts on how to accomplish this? --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Re: wordpress hooks and actions system in django?
While not exactly Django-specific, I wrote up an article[1] last month, describing an easy way to enable plugins in any Python application. I don't know if that's what you're looking for, but it's probably worth a look, anyway. -Gul [1] http://gulopine.gamemusic.org/2008/jan/10/simple-plugin-framework/ --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Djangos Dispatcher does this, the sender gets the results back from the receiver. I do not believe Django makes use of this anywhere (but have not checked to be sure) To write a plugin manager in your case you would have to write your own sender, so that each consecutive plugin listening to a particular signal, got the results from the previous plugin not the unmodified results Totally Untested example based on the webcast you linked to ( http://dpaste.com/36295/ ) The majority of your work would come in creating the signals, and what each signal should contain and where it should be sent from --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

This sounds like a good application for the Dispatcher in Django ( http://code.djangoproject.com/wiki/Signals ) You write your own signals, that the plugins will listen for, they manipulate the data they need and the dispatcher returns all the responses. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.
