blogapp2's Issues

復習する必要あり

user.rbのこの部分をあまり理解できていない!

カリキュラム:デイトラ 上級DAY3のTIPS 02

user自体にidが渡っている場合があるので

①userを渡してidを取得する場合と
②idを渡して取得する場合の

二つの場合に条件分岐しないとエラーが起こる らしい・・・

  def follow!(user)
    if user.is_a?(User)
      user_id = user.id
    else
      user_id = user
    end

    following_relationships.create!(following_id: user_id)
  end

課題
・commentがまだuserに紐づいていない
・strong paramsにuser_idをmerge

手順

  1. migrationファイルにt.references:user追加でrollback→migrate
  2. schema.rbの確認
  3. comment.rbにbelings_to
  4. user.rbにhas_many
  5. comments_controllerにstrong paramsでuser_idをmerge
  6. showにて
.comment_avatar
  =image_tag comment.user.avatar_image
