ruby-on-rails - MichaelHartlチュートリアル3.2-第9章-エラーメッセージと編集/更新ページの問題

Question

私はMichaelHartlRails 3.2に取り組んでおり、これらの問題に数時間悩まされています。正確であることを確認するために7、8、9のすべてのコードを調べたので、何が欠けているのか理解できません。ユーザーコントロールのプライベートセクションに追加するまで、更新/編集ページは機能していました。

それらを追加したので、手動でページをテストして設定を押すと、サインインページに直接移動します。signed_inでない限り、それはうまくいかないようですか？そして、ユーザーコントローラーページから署名ページにリダイレクトします。編集ページがサインインするために表示されないために私のテストが失敗する理由は理にかなっています。アイデアや提案をいただければ幸いです。他のページを見る必要がある場合は、私に知らせてください。

エラーメッセージ-以下のような9つのエラーが表示されます

この問題が発生した場合は、application_controllerにこれがないことを確認してください。これは私にあらゆる種類の悲しみを引き起こした非常に小さなエラーでした。繰り返しますが、このコードは使用しないでください…。

class ApplicationController < ActionController::Base
 protect_from_forgery
 include SessionsHelper

 private
def current_user
    @current_user ||= User.find(session[:user_id]) if session[:user_id]
end

Answer 1

カピバラはメールフィールドを見つけられません。

サインインフォームに記入する前に、それを実行する必要があります。このように機能を変更します：

def sign_in(user)
  visit signin_path
  fill_in "Email", with: user.email
  fill_in "Password", with: user.password
  click_button "Sign in"
  # Sign in when not using Capybara as well.
  cookies[:remember_token] = user.remember_token
end

私はあなたのフォームが正しく形成されていると思います。visit signin_pathの後に、puts page.htmlhtmlを表示し、save_and_open_pagelaunchyがインストールされているかどうかを追加できます。
