Thanks Brad,
I got it working.
@register.filter(name='price')
def price(model, user):
u = UserGroup.objects.get(user_id=user.id)
level = u.price_level
if level == 'B':
return model.price_b
if level == 'C':
return model.price_c
if level == 'D':
return model.price_d
if level == 'E':
return model.price_e
return model.price_a
{{ row|price:request.user }}
