filter is used to retrieve many records, get is used to retrieve 1
record.
if your are working with a ForeignKey on your Post model like so:
def Post(models.Model):
name = CharField()
author = model.ForgeinKey(Author)
and user is an object of type Author then this should give you all the
Posts for one Author.
user.post_set.all()
and
user.post_set.count() will give you number of posts of the user.
all this information is in the docs at:
http://www.djangoproject.com/documentation/db-api/
specifically
http://www.djangoproject.com/documentation/db-api/#related-objects and
http://www.djangoproject.com/documentation/db-api/#count
