Rails 5.2 + sorcery で認証

Last updated at Posted at 2019-05-13

備忘録です

はじめに

devise をとりあえず入れとこうとなるかと思いますが、ライブラリとして重たいので、軽量で、最低限の認証機能を作れる sorcery を使ってみようと思います。

公式サイト

GEM: https://rubygems.org/gems/sorcery
GITHUB: https://github.com/Sorcery/sorcery

環境

$ rails -v
Rails 5.2.3
$ ruby -v
ruby 2.5.1p57 (2018-03-29 revision 63029) [x86_64-darwin18]

導入

./Gemfile
...
+ gem 'sorcery'
$ bundle install
...
$ bundle exec rails generate sorcery:install
 create  config/initializers/sorcery.rb
    generate  model User --skip-migration
      invoke  active_record
      create  app/models/user.rb
      insert  app/models/user.rb
      insert  app/models/user.rb
      create  db/migrate/20190513001622_sorcery_core.rb
