Django affiliate program script - how?

Question

Django

Hello.
What should be the main focus when writing an affiliate program script with online payments, something like this glopart.ru. Are there people who have already done something similar? - I would like to discuss this issue in more detail.
How to develop a model so that when registering, a user is assigned a unique id (something like this - your id001547. Well, although the user id can be his login or e-mail), when adding a product to the system, a unique id is also assigned (such as this product id 302154, etc.), the affiliate program should be multi-level and all the questions that follow from this. I’m not asking you to write the code itself, but you need the very explanation of how this can be done from which to push off and start.
