Any plans to format the code so it appears properly indented (and hence readable)? Thanks!

Any plans to update this soon (make use of your Google-foo while you still have it!)

No, they should not be asynchronous to begin with. That would be an utter nightmare and very literally break many things in Django.

I have this same situation, did you find a solution?

I've a serious problem with signals. I have a base non-abstract model, and several child models that inherits from that base model. I registered signals for the base model and all of it's child models, but the signals are fired up when the child is saved, not when the base it's saved.

This is a great solution, but shouldn't signals be asynchronous to begin with? Django should spawn a thread to send the signals right? Then we wouldn't need to worry about this. This, of course, has nothing to do with you, I'm just venting. Thanks very much for the useful post

Nice post Chris. May be you should think about updating your code samples for Django 1.0, since Google returns your post at the top. Cheers

Thanks for the post Chris, this was really useful just in understanding how to do asynchronous processing. I note the other posts that some of the exact content may be out of date now, but you've given me some great pointers in here to solve my problem.

I think this is old, dispatcher seems not to have the method connect any more :(

Because then I'd lose all the nice link juice I get from this post to the Django documentation ;). Seriously, though, you're probably right; I should do that. If nothing else, it could be added to the Django Wiki.

Actually, Django's signal documentation has improved greatly with Django's 1.0 milestone release, and my post is here is now a little out dated. I've been meaning to come back and update it. When I get around to doing that, I'll see if there's anything meaningful to add to Django's documentation, itself.

Thanks for the suggestion.

Wondering why not submit this work as a patch to the signals documentation? Seems like a few examples on the signals page would be immensely useful.

Very clear and useful post!

@Wes: I'm glad it helped you out. Surprising, Django's signal documentation is still rather lacking. With such a crucial aspect as this, it continually amazes me that so little writing is devoted to it. Sadly, this tutorial is now rather out of date if you're running the new Django 1.0 release. I'm hoping to update it or create another version in the near future, since it seems to have helped alot of people.

@coulix: I'll look into that. When I first posted this 8 months ago, there was really nothing out there like that. A couple of queuing apps were starting to pop up, but most were in planning or alpha.

if you dont want to user threading you could use the django-mailing app.

I really appreciate this tutorial. I've read all of the other signal documentation you linked, but this is the post I keep coming back to as a reference when I need to deal with signals.

Great! Thanks for the info.

That was an incredibly clear code walk through. Feel free to write more about django just about anytime you want ;)

Thanks!

That's very useful. Nice usage of the thread library.
