Well, that is weird. MayRelatedManager definitely *does* have an
attribute 'remove'. With these basic models:
class Category(models.Model):
title = models.CharField(_('title'), max_length=100)
class Post(models.Model):
title = models.CharField(_('title'), max_length=200)
categories = models.ManyToManyField(Category)
the following works fine:
>>> from blog.models import Post, Category
>>> p=Post.objects.create(title='dan')
>>> c=Category.objects.create(title='category')
>>> p.categories.all()
[]
>>> p.categories.add(c)
>>> p.categories.all()
[<Category: category>]
>>> p.categories.remove(c)
>>> p.categories.all()
[]
So it works for me, I can't imagine what is happening with your setup.
