Ruby on Rails RSpec放置方法未在用戶

Question

中看到簽名，所以我一直在使用Michael Hartl的教程一段時間，我可以說這真的很有用，但有一個問題，我覺得它不在教程的一部分。因此，在「9.2.2要求正確的用戶」一章中，我們將檢查用戶是否既不能訪問其他用戶的編輯頁也不能提交直接的PUT請求。

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

    describe "visiting Users#edit page" do 
    before { visit edit_user_path(wrong_user) } 
    it { should_not have_selector('title', text: full_title('Edit user')) } 
    end 

    describe "submitting a PUT request to the Users#update action" do 
    before { put user_path(wrong_user) } 
    specify { response.should redirect_to(root_path) } 
    end 
end 

只要一切似乎是正確的，但測試失敗：

1) Authentication authorization as wrong user submitting a PUT request to the Users#update action ←[31mFailure/Error:←[0m ←[31mspecify { response.should redirect_to(root_path }←[0m←[31mExpected response to be a redirect to <http://www.example.com/> but was a redirect to <http://www.example.com/signin>←[0m←[36m # ./spec/requests/authentication_pages_spec.rb:107:in `block (5 levels) in <top (required)>'←[0m 

這裏的用戶控制器：

class UsersController < ApplicationController 
before_filter :signed_in_user, only: [:index, :edit, :update] 
before_filter :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 create 
    @user = User.new(params[:user]) 
    if @user.save 
    sign_in @user 
    flash[:success] = "Welcome to the Sample App!" 
    redirect_to @user 
    else 
    render 'new' 
    end 
end 

def edit 
end 

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

private 

    def signed_in_user 
    unless signed_in? 
     puts "No user signed in" 
    store_location 
     redirect_to signin_path, notice: "Please sign in." 
    end 
    end 

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

因此，大家可以看到的問題是，當使用RSpec的放法，即使在檢查合適的用戶之前測試也會失敗，因爲它認爲沒有用戶登錄。 這是一個很容易被忽略的小問題（不正確的用戶不能使用d直接請求PUT），但這對我來說是一個難題，爲什麼它不能正確工作，我已經很久沒有得到答案了。

Answer 1

看起來signed_in_user過濾器會在correct_user觸發之前重定向回登錄頁面。這表明用戶實際上沒有通過之前的塊中的sign_in user調用正確登錄。

您是否在spec/support/utilities.rb中定義了sign_in？

include ApplicationHelper 

def sign_in(user) 
    visit signin_path 
    fill_in "Email", with: user.email 
    fill_in "Password", with: user.password 
    click_button "Sign in" 
    # Sign in when not using Capybara as well. 
    cookies[:remember_token] = user.remember_token 
end
