描述

I was able to register two accounts with usernames sabachanna and Sabachanna. It did not give duplicate username error. It is not able to capture lower case or title case differences. I tried to look into it but mongodb does not support case-insensitive queries.

Should we store the username as all capital or all lower in mongodb and then, on registration, convert the given username to upper case to see if duplicate is already available or not. Should we consider this on presentation layer?

研究方向
Look at the user model (likely a Mongoose schema) and the registration controller (e.g., server/api/user/user.controller.js). Change the username field to store lowercase version and modify the validation to compare case insensitively, either by using a case insensitive MongoDB index or by converting the input to lowercase before querying. Consider migrating existing duplicate usernames if needed, and ensure the presentation layer displays the original case.
