more than two couponuser count

[dedepene]

hi there!

Can't quite put my finger on it and why it's happening, but if a user has used two different coupons (showing twice as a coupon user in admin), any attempt for the same user to use a coupon ever again causes this error. At first glance it has to do with the .get() call in your validations.py. Not quite sure though why in the end it raises MultipleObjecstReturned:

Variable | Value
-- | --
args | ()
clone | <QuerySet [<CouponUser: testuser10>, <CouponUser: testuser10>]>
kwargs | {'user': <SimpleLazyObject: <User: testuser10>>}
limit | 21
num | 2
self | <QuerySet [<CouponUser: testuser11>, <CouponUser: testuser11>, <CouponUser: testuser10>, <CouponUser: rado>, <CouponUser: rado>, <CouponUser: piratko>, <CouponUser: piratko>, <CouponUser: testuser10>]>
