Ruby on rails 튜토리얼 - 통합 테스트 - 유효/유효하지 않은 사용자 정보 로그인 실패 - user_param 문제?

Question

Michael Hartl의 Ruby on Rails 튜토리얼에서 장기 휴가 (1 년) 후 연결이 끊어졌습니다. 통합 테스트에서 user_param 오류가 발생했습니다. 필자는 문서를 비롯한 강력한 매개 변수에 대해 잘못 이해할 수있는 원인을 파악하기 위해 4 곳의 출처를 살펴 보았습니다.

지난 주에 다시 시작한 이래로 일반적으로 튜토리얼 프로젝트를 알게되어 4 시간이 걸렸으며 7-12 시간에 걸쳐 12 시간을 읽은 다음이 문제를 쫓아 왔습니다. 나는 내가이 물건들에 너무 빨리 스캔해야하는 것처럼 느껴지고있다. & 나는 추적 오류가 좋지 않다는 것을 날카롭게 알고있다.

내가 누락 된 부분에 대해 알려 주실 수 있습니까? 이 유형의 문제를 촬영하는 데 문제가 있으면 알려주고 싶습니다. 시간 내 줘서 고마워! user_signup_test 여기

PasswordResetController : 나는 당신이 user 매개 변수 전에 params 키를 제거해야한다고 생각

    before_action :valid_user,  only: [:edit, :update] 
    before_action :check_expiration, only: [:edit, :update] # Case (1) 

    def new 
    end 

    def create 
    @user = User.find_by(email: params[:password_reset][:email].downcase) 
    if @user 
     @user.create_reset_digest 
     @user.send_password_reset_email 
     flash[:info] = "Email sent with password reset instructions" 
     redirect_to root_url 
    else 
     flash.now[:danger] = "Email address not found" 
     render 'new' 
    end 
    end 

    def edit 
    end 

    def update 
    if params[:user][:password].empty?     # Case (3) 
     @user.errors.add(:password, "can't be empty") 
     render 'edit' 
    elsif @user.update_attributes(user_params)   # Case (4) 
     log_in @user 
     flash[:success] = "Password has been reset." 
     redirect_to @user 
    else 
     render 'edit'          # Case (2) 
    end 
    end 

    private 

    def user_params 
     params.require(:user).permit(:password, :password_confirmation) 
    end 

    # Before filters 

    def get_user 
     @user = User.find_by(email: params[:email]) 
    end 

    # Confirms a valid user. 
    def valid_user 
     unless (@user && @user.activated? && 
       @user.authenticated?(:reset, params[:id])) 
     redirect_to root_url 
     end 
    end 

    # Checks expiration of reset token. 
    def check_expiration 
     if @user.password_reset_expired? 
     flash[:danger] = "Password reset has expired."

, 예를 들면 :

또한 당신이 pry와 컨트롤러의 매개 변수를받은 디버깅 할 수 있습니다

test "invalid signup information" do 
    get signup_path 
    assert_no_difference 'User.count' do 
    post users_path, user: { name: "", 
          email: "user@invalid", 
          password: "foo", 
          password_confirmation: "bar" } 
    end 
    assert_template 'users/new' 
    assert_select 'div#error_explanation' 
    assert_select 'div.field_with_errors' 
end 

:

• gemfile에 pry을 추가하십시오 (아무도없는 경우).
• run $ bundle install;
• user_params이 호출되기 전에 컨트롤러에 binding.pry을 추가하십시오.
• params에 예상 매개 변수가 들어 있는지 확인하십시오.
