Uppdatering av databas och Python version

[TobbeEdgeware]

Plan that is also under Project:

We use currently

• Google App Engine
  • Python 2.7
• ndb data base + API
• Google user login/authorization
• Memcache
• Tasks for conversions
• dev_appserver.py for local development

Changes needed

• Do conversions that we need
• No app-engine specific code
• Python >= 3.7
• cloudndb API towards same data base
• New login + role data base
  • Could be ScoutID
• Redis if caching needed
• New way for tasks

Steps forward

1. Still in Python 2.7 and dev_appserver.py
   1. Remove user login/authorization -> add comments (new decorator)
   2. Remove caching -> add comments
   3. Remove tasks -> add comments
2. Pure application Python 2.7
   1. run main.py directly
   2. Replace ndb API with cloudndb
      1. Run as local app
      2. Connect to online database or run emulator
   3. Remove rest of app-engine api
3. Change app to Python 3
   1. Change all code to Python 3
   2. Run as local app
      1. Connect to online database or run emulator
   3. Add user/authorization
   4. Add caching if needed
   5. Add tasks if needed
