Notes

2020-01-08

• Planning to use amazon s3, research Active Storage in Rails.
• Authorization: JWT and Bcrypt. Add roles attribute to Users model.

2020-01-09

• enum type in Ruby model adds '?' and other methods: https://api.rubyonrails.org/v5.2.4.1/classes/ActiveRecord/Enum.html
• trouble using enum with validates inclusion: {in:}
• Was planning on using self-join for Provider and Patient Models: https://guides.rubyonrails.org/association_basics.html#self-joins. Instead decided to create aliases for foreign keys.

2020-01-15

• enums in Rails are fun, and they add some useful methods for free.

2020-01-16

• process for creating a new encounters form route:

  • rails g model model_name encounter:references field
  • add has-one to encounter model
  • create controller
  • add get and patch routes to routes.rb
  • add to seeds.rb file
  • rails db:migrate
  • rails db:reset
  • test in postman

2020-01-17

• use rails:credentials:edit for secrets and private keys
• gem "aws-sdk-s3", require: false
• https://edgeguides.rubyonrails.org/active_storage_overview.html#setup

2020-01-21

• importing ICD10 file Section111ValidICD10-Jan2020.csv
• implement text search User.where("username like ?", "%olitreadwell%")
• ActiveStorageImported ICD10 csv file with exactly 65535 rows, so probs not complete list.
• ActiveStorage works with <input type="file" />. Still failing on base64 image from camera.

2020-01-22

• setting up S3 in ActiveStorage.

• access keys were saved in .csv

• EDITOR="code --wait" bin/rails credentials:edit ,

• or add export EDITOR="subl --wait" to shell profile and run bin/rails credentials:edit

• don'f forget Procfile for Heroku:

• don't forget master.key content environment variable to rails.

• 10000 record Heroku limit hit on Icd10 csv. Gotta whittle it down.

SWAGGER Docs
