DEVELOP 06: Presentation Layer Refactoring

[jerry914]

1. Manage user sessions:

   • [x] Use cookie-based sessions to maintain any history or information about the user’s experience
   • [x] Configure Roda to use cookies to manage user sessions
   • [x] Create a hashing secret for the cookies (Use: rake new_session_secret - in Rakefile)

2. Add error-checking to your routes

   • [x] Distinguish the steps of each route (get data from API, store data in DB, etc.) and leave simple comments in your code identifying these steps
   • [x] Check and catch errors at each step:
   • [x] Use conditional logic (e.g, if-else) to check the validity of the output of steps
   • [x] Catch (rescue) expected or unexpected errors in each step
   • [x] Display notice / error flash messages (cookie-based)

3. Refactor your views

   • [x] Identify all the places your views use domain objects (entities/values)
   • [x] Create View Objects in your domain
   • [x] Implement the major functionality your views need
   • [x] Some view object methods might simply call the same method on domain objects
   • [x] Give descriptive names to the complex behavior
   • [x] You might have to make several view objects corresponding to smaller entities and values
   • [x] Ensure controller is only passing a view objects to views
   • [x] Refactor views (e.g., slim files) to only use view objects

4. Deploy to Heroku

   • [ ] Merge your refactor-presentation branch into main and push both branches to Github
   • [ ] Deploy your updates to main branch on Heroku
   • [ ] Don’t forget to add a SESSION_SECRET environment variable to Heroku

• Please deploy your application to Heroku and share the link to the team spreadsheet!
• Please notice 2 issues in your git control:
  • Direct Changes to main: There would be risks of breaking the stable version.
  • Clear Feature Completion Stage: The refactor-presentation PR merge happened before further changes; this makes it harder to track progress.
