How to generate unique urls to track user signups?
问题 I want to generate a unique url for each user that signs up for my app. The urls should all lead to the same sign up page but each one will be associated with the one user that received it when signing up. Then every time a new user signs up through the unique url, the number of signups associated with that url will increment by one. Therefore, I can track the number of signups generated by each user. How do I build such a system? This is for a Ruby on Rails app. 回答1: i am not exactly sure
