Small issue compilation

[kkoehn]

Must have before release:

• Exercise to task refactor
• active storage
• automatic collection creation and assignment on import from CO

Functionality

• You have to verify your mail after registration, but not after a change (of the email address)
  • fix
• simple_form is not used consistently
  • fix when necessary
• A user can message himself (and reply)
  • Message system in general is questionable
    • refactor message system -> notification system
• A Report-system seems to exist, but has not much functionality
  • auto hide exercise after X amount of reports
• Messages in message-system do not show timestamps
  • fix after notification system?
• Exercise can have multiple files with the same path
  • fix
• Emails and internal Messages are handled separated from each other (example groups_controller l:68&70)
  • fix with notification system
• Export to AccountLink from Cart currently disabled
  • will be deleted anyway
• Error during import (no file for example) results in JS alert and only generic error message
  • better error message
• In exercise new form - uploaded files will be "forgotten" after a serverside validation error
  • fix
• The description preview in the overview should show the primary description
  • task only has one description - will fix itself
• Specs missing for: ability, groups_controller, probably a lot more
  • add when necessary
• After requesting to contribute to a exercise, it redirects back to the own exercises. The old filter should be reapplied or no redirect should occur (ajax)
  • fix
• In Exercise show: when opening related exercises, comments, history it always scrolls to the bottom
  • fix
  • opening related exercises, when none are present still shows the navigation arrows left and right
    -fix
• check for dead actions, views
  • fix when necessary
• Long titles break formatting in exercise overview
  • fix
• Missing FileTypes cause errors on both systems
• Password reset doesn't work: password controller and routes got deleted in a refactoring

potential Features:

• ability to ignore a specific Exercise in exercise-overview
• ability to attach a personal note to an exercise
• discussion per exercise/group/collection?
• Markdown?-Editor for descriptions of exercise
• show import/export links for current systems while creating account link (on both CH and CO)
• add more right levels per exercise
  • user can request access to an exercise and append a message
  • exercise owner can choose which level of access the user gets (or reject completly)

Refactoring

• Split large controllers, move more logic to services
• Exercise uses a default_scope. This is an antipattern
• ruby update introduced a lot of warnings. check stdout

Styling

• Form errors are not correctly used in all forms
• Html titles is always "CodeHarbor"
• Main Page: Padding/margin between three circles missing

Technology

• Paperclip is deprecated, switch to Active Storage
• !!! FIX !!!
• Sprockets update?
• Yarn?
• Bootstrap 4? (we use twitter-bootstrap-rails, which seems sparely updated)
• Ransack for Exercise search

Discovered during Code Review:

• Select2 gets duplicated when moving back and forth (caused by turbolinks)
• "Show Related" on /exercises renders arrows without content if no exercises are related

[kkoehn]

• uuid and parent_uuid are not changable via edit > update
