我一直在運行M.Hart的Rails教程。在其中一個部分中,您可以爲每個不屬於您自己的用戶在用戶索引頁面上實施刪除鏈接;提供你是一個管理員用戶。我也想實現一個刪除鏈接到每個用戶的個人資料頁面。我把刪除鏈接代碼放入了部分內容中,並且它在索引頁面和單獨的用戶展示頁面上運行良好,但在將show部分添加到show page代碼後,我仍然收到RSpec失敗。我的代碼在下面...順便說一句 - 主用戶與管理員用戶相同。Rails RSpec MHart的教程用戶刪除鏈接

用戶/ show.html.erb

<section> 
    <%= gravatar_for @user %> 
    <h3><%= @user.name %></h3> 
    <div id="profile_delete_link"><%= render 'shared/user_delete_link', user: @user %></div> 
</section> 

共享/ user_delete_link(局部 - > _user /刪除/ link.html.erb)

<% if !current_user?(user) && current_user.master? %> 
    >> <%= link_to "delete", user, method: :delete, data: { confirm: "You sure?" } %> 
<% end %> 

user_pages_spec.rb - 下面>代碼是如果部分(以上)添加到用戶/顯示代碼中,該規格會中斷。當局部被刪除這些規範回去綠色

describe "profile page" do 
let(:user) { FactoryGirl.create(:user, name: "foo bar") } 

let!(:mp1) { FactoryGirl.create(:micropost, user: user, content: "Foo") } 
let!(:mp2) { FactoryGirl.create(:micropost, user: user, content: "Bar") } 

before { visit user_path(user) } 

it { should have_selector('h3', text: user.name) } 
it { should have_selector('title', content: "F.Bar") } 

describe "microposts" do 
    it { should have_content(mp1.content) } 
    it { should have_content(mp2.content) } 
    it { should have_content(user.microposts.count) } 
end 

user.rb

# == Schema Information 
# 
# Table name: users 
# 
# id    :integer   primary key 
# name   :string(255)

email_regex = /^[_+a-z0-9-]+(\.[_a-z0-9-]+)*@[a-z0-9-]+(\.[a-z0-9-]+)*(\.[a-z]{2,4})$/i 

attr_accessible :name, :email, :password, :password_confirmation 
has_many :microposts, dependent: :destroy 

    validates :name, :presence => true, :length => { within: 2..40 } 
    validates :email, :presence => true, :uniqueness => { case_sensitive: false }, :format => { with: email_regex } 
    validates :password, :presence => true, :length => { within: 5..50 } 
    validates :password_confirmation, :presence => true 

def feed 
    Micropost.where("user_id = ?", id) 
end 
end 

user_controller.rb表演和索引行動以及過濾器之前

before_filter :authorize,  only: [:index, :edit, :update, :destroy] 
before_filter :correct_user, only: [:edit, :update] 
before_filter :master_user, only: [:destroy] 

def index 
    @users = User.all 
end 

def show 
    @user = User.find(params[:id]) 
    @microposts = @user.microposts.paginate(page: params[:page]) 
    @title = initials_of @user.name 
end 

如果您希望發佈任何代碼或添加更多信息,請讓我知道:)謝謝。 ANCE。

更新: RSpec的錯誤:

UserPages profile page microposts 
Failure/Error: before { visit user_path(user) }

    undefined method `master?' for nil:NilClass

SessionsHelper:

module SessionsHelper

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

完成:)上述rspec錯誤適用於所有11個規格失敗 – 2013-04-26 03:17:46

您的測試如何登錄,因此current_user已設置? – 2013-04-26 03:19:25

這是什麼反應告訴你的是,當它叫大師?在current_user對象上,current_user對象爲Nil,這意味着它不存在。

這意味着@current_user當前沒有定義,並且User.find也沒有找到用戶。

您正在將@user傳遞給您的部分,所以我認爲您的條件應該基於@user。

希望這是有道理的
