You aren't returning anything here. Add "return user_products" to the
end of the function or do anything with user_products. As it is now,
the queryset simply gets lost somewhere.

I'm quite sure you cannot pass a function into a template. This only
works for functions / methods attached to objects. {% for i in
obj.function %} might work, {% for i in function %} will not.
Write user_products = my_callback()
It seems you are quite confused though. What is it you want to do? It
makes no sense to use the same function (my_callback) as a handler for
request_finished and inside a view function.
