gitのソースツリーに含まれるgit-completion.zshをzshで使う手順


注意：gitコマンドがhubコマンドへのエイリアスに設定されている場合は補完が働かない。


補完用ファイルを置くディレクトリを作成する（既に同じ用途のディレクトリがある場合はそれを使う）。


$ mkdir ~/.zsh/completion/

ActiveRecordモデルにおけるAssociationのバリデーション戦略


    

  • foo_idのpresenceでは、存在しないIDでも保存できてしまう

      

    • fooを参照した際はnilが返る
      • 

    

    • 

  • fooのpresenceを指定すると、foo_idへの代入ではバリデーションを通らなくなる

      

    • fooに未保存のオブジェクトを代入してsave!するとPG::NotNullViolationが発生する

        

      • PG::NotNullViolation: ERROR:  null value in column "character_id" violates not-null constraint
        • 

      

      • 

    

    • 

  • Polymorphic association

      

    • validates :foo_type, presence: trueは不要
      • 

    

    • 

  • クラスが存在しない場合はsave!時にNameError: uninitialized constant XXXが発生する
    •
