Re: Detecting modifications in ManyToMany field
With the m2m changed signal I can only have the state of the object after it has been saved. Not the difference between before and after the change.

Detecting modifications in ManyToMany field
Hello, I would like to detect changes in a ManyToMany field, to update data in the linked Model. I've two objects : class Category(models.Model): some fields ... class Post(models.Model): some fields ... categories = models.ManyToManyField(Category) And I would like to detect (in the admin and when accessing the object in python) when categories are added or removed to a Post. To update some fields in the Category model. But I've tried with : * django.db.models.signals.m2m_changed, but it doesn't appear to be trigged in the admin * by overriding Post.save(), but I get the same information before and after the save() (I think it's because m2m are handled after save() has finished) : def save(self, *args, **kwargs): print Post.objects.get(pk=self.id).categories.all() super(Post, self).save(*args, **kwargs) print Post.objects.get(pk=self.id).categories.all() Any solutions to handle this case ?

ORM API and applications best practice
Hello, I'm currently rewriting an old Django project (the original was build on Django 0.95), and I'm trying to rewrite it with the best practice. My application is centered around a Clubber model which extend the built-in User model. So the models are currently : In the clubber app: class Clubber(models.Model): user = models.ForeignKey(User, unique=True) avatar = models.ImageField() [ ... other fields ... ] In the messagin app: class InternalMessaging(models.Model): from = models.ForeignKey(Clubber) to = models.ForeignKey(Clubber) content = models.TextField() It allow me to easily access the clubber avatar from the message with message_instance.from.avatar, but it had the drawback to force me to bundle the Clubber app if I would like to re-use the messaging app. I would like to use the User in the internal message instead of the Clubber, but now I can't access the avatar field in a good way (with select_related()). What is the good solution to solve this problem ? Thanks -- Fabien SCHWOB --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Best practices to provide Django on a shared host
Hello, I'm currently hosting my Django websites on a dedicated server and it works fine. I restart Apache when I make modifications since I'm alone on the box. But I've made evangelism for Django and I've convinced some friends to use it. So I would like to take a new server and to set up a "Django Shared Hosting". What is the best way to do that ? - One Apache instance by user/website (I've seen that on http://www.gypsyhosting.com/) ? But how to do that does someone have some links to do that ? - Using lighttpd and FGCI ? - Using Apache and FCGI, so the user only need to *touch* the fcgi script. My goal is to build my shared hosting and to create a document on how to do that. So, any help are welcome.

Creating a decoration for the views
Hello, I've some code which is duplicated between all my views and it violate the DRY principle. So, I would like to use the decorators to eliminate the duplicated code. Does someone has a simple example on how to do that. The code I would like to factorise is the following one : if 'is_logged' not in request.session: request.session['is_logged'] = False if 'user_id' in request.session: unread_messages_count = InternalMessage.objects.filter(to_clubber__id=request.session['user_id'],read=False).count() total_messages_count = InternalMessage.objects.filter(to_clubber__id=request.session['user_id']).count() else: unread_messages_count = total_messages_count = None To summarize, I would like to : - populate the function namespace with some vars - manipulate the sessions Thanks --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.
