試したこと

users_controller,session_controllerをtutorialの通りに修正しましたが改善されません。

補足情報（FW/ツールのバージョンなど）

Answer 1

account_activations_controller.rbを下記のように修正するとエラーが解決しました。

修正前

   def edit
        user = User.find_by(email: params[:email])
        if user && !user.activated? && user.authenticated?(:activation, params[:id])
            user.update_attribute(:activated_at,Time.zone.now)
            log_in user
            flash[:success] = "Account activated!"
            redirect_to user
        else
            flash[:danger]  = "Invalid activation link"
            redirect_to root_url
        end
    end

修正後

def edit
    user = User.find_by(email: params[:email])
    if user && !user.activated? && user.authenticated?(:activation, params[:id])
      user.update_attribute(:activated,     true)
      user.update_attribute(:activated_at,  Time.zone.now)
      log_in user
      flash[:success] = "Account activated!"
      redirect_to user
    else
      flash[:danger] = "Invalid activation link"
      redirect_to root_url
    end
  end
