self-introduction | Web3D & Anime & Hello | Frontend Framework library

So let me start with the registration process in my web page. The user would register first, and then right after registration, he/she is redirected to a page where the user has to input his/her personal info, such as self-introduction, full name, etc. When the user completes filling his/her personal info in, then the user will be redirected to home page.

So what I wanted to do is this: When the user tries to access home page, check if he/she is logged in. If yes, check if he/she has filled in the personal info. If no, redirect the user to register page. If the user has filled in (=matching query exists), redirect him/her to the home page. If not, redirect him/her to the personal info page, to fill the fields in.

And here's my code in views.py
