Question

正如标题所说，我正在关注Michael Hartl的RoR Book，我目前正在进行第9.3章 - 显示用户。所有测试都在本章之前通过，我正在阅读本书的Rails 4版本，我对这个RoR很新。

我确实捆绑了exec rspec spec /并得到了这个错误

1）用户中未登录用户的身份验证授权   控制器访问用户索引        失败/错误：它{should have_title（'登录'）}          预期#has_title？（“登录”）返回true，得到错误        './spec/requests/authentication_pages_spec.rb:80:in'块（6级）in'

2）用户页面索引        失败/错误：访问users_path        ::的ActionView ::模板错误：          错误的参数数量（2为1）        ＃./app/helpers/users_helper.rb:4:in gravatar_for' # ./app/views/users/index.html.erb:7:in阻止_app_views_users_index_html_erb__3697129218785207645_26541860'        './app/views/users/index.html.erb:5:in _app_views_users_index_html_erb__3697129218785207645_26541860' # ./spec/requests/user_pages_spec.rb:12:in阻止（3级）'

在3.16秒完成66例，4次失败

失败的例子：

这是我的authentication_pages_spec.rb

  require 'spec_helper'

  describe "Authentication" do

    subject { page }

    describe "signin page" do
      before { visit signin_path }

      it { should have_content('Sign in') }
      it { should have_title('Sign in') }
    end

    describe "signin" do
      before { visit signin_path }

      describe "with invalid information" do
        before { click_button "Sign in" }

          it { should_not have_selector('div.alert.alert-error') }

      end

        describe "followed by signout" do
          before { click_link "Sign out" }
          it { should have_link('Sign in') }
        end
      end
    end
    describe "authorization" do

      describe "for non-signed-in users" do
        let(:user) { FactoryGirl.create(:user) }
        describe "when attempting to visit a protected page" do
          before do
            visit edit_user_path(user)

            click_button "Sign in"
          end

          describe "after signing in" do

            it "should render the desired protected page" do
              expect(page).to have_title('Edit user')
            end
          end
        end

        describe "in the Users controller" do

          describe "visiting the edit page" do
            before { visit edit_user_path(user) }
            it { should have_title('Sign in') }
          end

          describe "submitting to the update action" do
            before { patch user_path(user) }
            specify { expect(response).to redirect_to(signin_path) }
          end

          describe "visiting the user index" do
            before { visit users_path }
            it { should have_title('Sign in') }
          end
        end
      end

      describe "as wrong user" do
        let(:user) { FactoryGirl.create(:user) }
        let(:wrong_user) { FactoryGirl.create(:user, email: "wrong@example.com") }

        describe "submitting a GET request to the Users#edit action" do

          specify { expect(response).to redirect_to(root_url) }
        end
      end
    end
  end

这是我的users_controller.rb

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

  def index
    @users = User.all
  end

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

  def new
    @user = User.new
  end

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

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

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

  private

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

    # Before filters

    def signed_in_user
      unless signed_in?
        store_location
        redirect_to signin_url, notice: "Please sign in."
      end
    end

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

这是我的user_pages_spec.rb

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

  def index
  end

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

  def new
    @user = User.new
  end

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

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

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

  private

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

    # Before filters

    def signed_in_user
      unless signed_in?
        store_location
        redirect_to signin_url, notice: "Please sign in."
      end
    end

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

我真的不知道出了什么问题，请指出正确的方向。

Answer 1

这看起来像是模板错误。

一个错误指向此文件：/app/helpers/users_helper.rb第4行，看起来gravatar_for中的参数数量错误。接下来要看的是/app/views/users/index.html.erb第7行。

Answer 2

我明白了。

问题在于gravatar_for参数。

我犯了错误，并且没有更新users_helper中的gravatar_for方法，这就是提供此错误的内容。

def gravatar_for(user, options = { size: 50 })
  gravatar_id = Digest::MD5::hexdigest(user.email.downcase)
  size = options[:size]
  gravatar_url = "https://secure.gravatar.com/avatar/#{gravatar_id}?s=#{size}"
  image_tag(gravatar_url, alt: user.name, class: "gravatar")
end

更新了gravatar_for方法。
