rubyrails教程第10章错误

Question

我在 Michael Hartls Ruby 关于 Rails 教程的第 10 章中遇到了 8 个错误。在测试 10.2.2 之前，一切都很好。我不知道如何解决它......我希望你能帮忙。提前致谢。

错误信息：

user_controller_test 文件:

users_controller 文件:

      redirect_to @user

      unless logged_in?
        flash[:danger] = "Please log in."
        redirect_to login_url
      end
    end

    # Confirms the correct user.
    def correct_user
      @user = User.find(params[:id])
      redirect_to(root_url) unless @user == current_user
    end
    end
end

错误发生在10.2.2的指令之后。 10.2.1 测试正常。

Answer 1

看起来您在 users_controller 中有一个额外的 end，就在最后一个 - 第 58 行

之前

编辑：@SebastianPalma 所说的 - 打败了我:)

Answer 2

您在 User#correct_user 方法中有额外的结束。试试这个：

class UsersController < ApplicationController
  before_action :logged_in_user, only: [:edit, :update]
  before_action :correct_user,   only: [:edit, :update]

  def show
    @user = User.find(params[:id])
  end

  def new
    @user = User.new
  end

  def create
    @user = User.new(user_params)
    if @user.save
      log_in @user
      flash[:success] = "Welcome to the Sample App!"
      redirect_to @user
    else
      render 'new'
    end
  end

  def edit
    @user = User.find(params[:id])
  end

  def update
    if @user.update_attributes(user_params)
      flash[:success] = "Profile updated"
      redirect_to @user
    else
      render 'edit'
    end
  end

  private

  def user_params
    params.require(:user).permit(:name, :email, :password,
                                     :password_confirmation)
  end
  # Before filters

  # Confirms a logged-in user.
  def logged_in_user
    unless logged_in?
      flash[:danger] = "Please log in."
      redirect_to login_url
    end
  end

  # Confirms the correct user.
  def correct_user
    @user = User.find(params[:id])
    redirect_to(root_url) unless @user == current_user
  end
end

你注意到 if - 修饰符和 if -statment.you 的语法之间的区别，不必在 modifier.these 的末尾使用额外的 end 两者都是相同的，没有任何语法错误。

if c.empty?
  return
end

return if c.empty?
