Devise Sample

rails g devise User deviseの小文字・大文字は区別され、すべて小文字のdeviseのみ。既存のUserモデルがあれば、追加する形で作られる。

rails d devise --helpで、 rails d devise --helpで、rails generate devise NAME [options]という用法を見れる。

$ rails g --help | grep devise
  active_record:devise
  devise
  devise:controllers
  devise:install
  devise:views
  mongoid:devise

変に改行されて読みにくい。文単位で改行してみる。 Your bundle only supports platforms ["x86_64-darwin-20"] but your local platform is x86_64-linux. Add the current platform to the lockfile with bundle lock --add-platform x86_64-linux and try again.

"x86_64-darwin-20"ってのがmacOSの1つで、Herokuの環境がLinuxでx86_64-linuxでも使われることを指定しろって話みたい。 nokogiriとかは、環境によって、ちょっと異なるバージョンが入るらしい。環境ごとにバージョンがあるって感じなのかな。

Rubyで作られたアプリだと検知して、bundler 2.2.21をインストールし始める。 Gemfile.lockに書かれたBundlerのバージョンを削除する。で、2.2.21 bundlerを使って、Gemfile.lockからインストールしてる。

User.new(email: "foo@example.com", password: "foobar")

User.newするときはpasswordでよいが、中のカラムはencrypted_password.
