Howdy - today a weird problem occured to me:

I have a modle class in Django and added a custom property to it that shall not be saved into the database and therefore is not represent in the models structure:

class Category(models.Model):
    groups = models.ManyToManyField(Group)
    title = defaultdict()

Now, when I'm within the shell or writing a test and I do the following:

c1 = Category.objects.create()
c1.title['de'] = 'german title'
print c1.title['de'] # prints "german title"

c2 = Category.objects.create()  
print c2.title['de'] # prints "german title" <-- WTF?

It seems that 'title' is kind of global. If I change title to a simple string it works as expected, so it has to do something with the dict? I also tried setting title as a property:

title = property(_title)

But that did not work, too. So, how can I solve this? Thank you in advance!
