Hello,

I have the following models

class Book(models.Model):
        author = models.ManyToManyField(Author)
        pub_date = models.DateTimeField()
        ...

class Author(models.Model):
        tag = models.ManyToManyField(Tag)

class Tag(models.Model):
        name = models.CharField(max_length=20)

What I want to query for is:

The most used Tags (and their count) for all books who's pub_date is greater 
then today.

I can solve the last part 
Book.objects.filter(pub_date__gt=datetime.date.today())

But how do I count all the tags for all these books ?
