为什么这个rspec请求规范没有更新模型？

我有与User模型交互的请求规范。 我想确保具有Admin角色的用户可以创建/编辑/销毁用户。 我现在遇到问题，编辑操作不会更新用户。 当我手动浏览网站上的操作时，一切正常，但测试无法更新用户。

这是我的规格： 

it 'edits a user' do @user = FactoryGirl.create(:user) visit new_user_session_path unless current_path == new_user_session_path fill_in "Email", :with => @user.email fill_in "Password", :with => @user.password click_button "Sign In" user_to_edit = FactoryGirl.create(:user, first_name: "John", last_name: "Smith") visit edit_user_path(user_to_edit) unless current_path == edit_user_path(user_to_edit) fill_in 'user_last_name', with: "Changed" expect{ click_button "Do it" }.to change { user_to_edit.last_name }.from("Smith").to("Changed") page.should have_content "John Changed" end

我得到的错误是： 

 Failure/Error: expect{ result should have been changed to "Changed", but is now "Smith"

如果我将测试的最后几行更改为： 

  fill_in 'user_last_name', with: "Changed" click_button "Do it" page.should have_content "John Changed"

然后测试成功。 这似乎不正确，因为如果user_to_edit未更新，页面不应显示“John Changed”。

我的删除请求规范工作正常： 

 it "deletes a user" do @user = FactoryGirl.create(:user) visit new_user_session_path unless current_path == new_user_session_path fill_in "Email", :with => @user.email fill_in "Password", :with => @user.password click_button "Sign In" user_to_delete = FactoryGirl.create(:user, first_name: "John", last_name: "Smith") visit users_path unless current_path == users_path expect{ within ".user_#{user_to_delete.id}" do click_link 'Delete' end }.to change(User,:count).by(-1) page.should_not have_content "John Smith" end

我有一个用户模型： 

 class User  true, :on => :create validates :first_name, :presence => true validates :last_name, :presence => true before_save :set_phones def set_phones self.fax = Phoner::Phone.parse(self.fax).format("%a%n") unless self.fax.blank? self.land_phone = Phoner::Phone.parse(self.land_phone).format("%a%n") unless land_phone.blank? self.mobile_phone = Phoner::Phone.parse(self.mobile_phone).format("%a%n") unless mobile_phone.blank? end end

我有这个工厂： 

 require 'faker' FactoryGirl.define do factory :user do |f| f.first_name { Faker::Name.first_name } f.last_name { Faker::Name.last_name } f.email {Faker::Internet.email} f.password { "oq2847hrowihgfoigq278o4r7qgo4" } f.role { "admin" } end end

我在用户控制器中有这些操作： 

  def edit @user = User.find_by_id(params[:id]) respond_to do |format| format.html end end def update if params[:user][:password].blank? [:password,:password_confirmation].collect{|p| params[:user].delete(p) } end respond_to do |format| if @user.errors[:base].empty? and @user.update_attributes(params[:user]) flash.now[:notice] = "Your account has been updated" format.html { render :action => :show } else format.html { render :action => :edit, :status => :unprocessable_entity } end end end

routes.rb文件也是相关的，因为我正在使用Devise并拥有自定义用户控制器： 

  devise_for :users, :skip => [:sessions, :registrations] devise_scope :user do get "login" => "devise/sessions#new", :as => :new_user_session post 'login' => 'devise/sessions#create', :as => :user_session delete "logout" => "devise/sessions#destroy", :as => :destroy_user_session get "signup" => "devise/registrations#new", :as => :new_user_registration put "update-registration" => "devise/registrations#update", :as => :update_user_registration delete "delete-registration" => "devise/registrations#destroy", :as => :delete_user_registration get "edit-registration" => "devise/registrations#edit", :as => :edit_user_registration get "cancel-registration" => "devise/registrations#cancel", :as => :cancel_user_registration post "create-registration" => "devise/registrations#create", :as => :user_registration end resources :users, :controller => "users"

你被智能测试框架的外观所迷惑:)你肯定希望user_to_edit的db条目能够改变。 user_to_edit是一个局部变量，因此无论您单击哪个按钮， user_to_edit.last_name都不会更改。 试试{ user_to_edit.reload.last_name }
