Problem with django reverse relation on custom user model

Hi 

I have created an online store project where every product has a user who is the seller.
I wanted to access seller info from the product using reverse relation "product.user.sellar"
but it returns appname.Model.None
here is my usermodel and sellar model

(there is a spelling mistake seller is sellar)

Please help me I'm kind of stuck with the problem for two days
