[Answered ]-Getting AttributeError while registering my model to Django admin?

This should be

admin.site.register(UserProfile)
admin.site.register(Post)

Admin.site.register takes two parameters, the first is the model class and the optional second parameter is an admin class. In your code, you were passing another model as the admin class.
