python - Filter tags in relationship with other model in taggit -

i have 2 models: reviews , product:

class review(models.model):     user = models.foreignkey(user, related_name="user_blog")     tag = taggablemanager()      product = models.foreignkey(product)     review_text = models.textfield()      created = models.datetimefield(auto_now=true, auto_now_add=false)     updated = models.datetimefield(auto_now=true, auto_now_add=true)     hashtag = models.foreignkey(hashtag)  class product(models.model):     name = models.charfield(max_length=500) 

i want filter tags related product, i'm doing this:

review = review.objects.get(product=prod.id)   tag in review.tag:     print tag.name 

but i'm getting:
