Heroku Redirect non-www to www on Django website
I currently have a website domain with Bluehost. Bluehost cannot redirect https://example.com to https://www.example.com using 301 redirects since I am not hosting with them. Now in my DNS settings, I have a CNAME (Alias) record that points @ to <string1>.herokudns.com and I have another CNAME (Alias) that points www to <string2>.herokudns.com. I have contacted Bluehost and they said one solution would be to point both www and @ to <string1>.herokudns.com but that does not seem to be a redirection to me. How can I manage to redirect the naked domain to www within Heroku on Python? I cannot test them a lot since Bluehost TTL is 4 hours and I cannot manage to change my configurations fast. Appreciate any help in advance! -

How to get ManytoManyField's data from another model in Django?

In another model called Attendance I also have a field which also has many to many relationship with Student.
