I'm using django1.4 from svn trunk.
The models are as follows:
class Book(models.Model):
# some stuff
class Price(models.Model):
book = models.ForgeinKey(Book)
Each book can have many prices.
My query in view:
Book.objects.all().prefetch_related('price')
I got this error:
Cannot find 'price' on Book object, 'price' is an invalid parameter to
prefetch_related()
Am I missing something? or prefetch_related cannot handle reverse
lookup.
Thanks in advance.
