问题 I built a chess app with Python and used Flask to create a site for users to play on. I used Heroku to deploy the app (http://pythonchessapp.herokuapp.com/). I am new to web development and was wondering how I can handle multiple users (on separate laptops or tabs) going on the site to play the app? Something like having a unique game id per user to serve a different game to different requests. Below is some of my code for routes and initializing games. I basically initialize a Board object

问题 So when I go to re-deploy my heroku, some of my profiles are missing photos, and the same ones every single time. When I upload a user photo, I can see a copy of it being put into my AWS bucket.

问题 The Heroku documentation at https://devcenter.heroku.com/articles/deploying-to-a-custom-rails-environment says I shouldn't use a staging.rb file to define my staging environment. It may be tempting to create another custom environment such as “staging” and create a config/environments/staging.rb and deploy to a Heroku app with RAILS_ENV=staging. This is not a good practice. Instead we recommend always running in production mode and modifying any behavior by setting your config vars. I think
