Question

我试图在我的网站上使用RSpec＆amp; amp;水豚。我们的想法是，文章只能由广告管理员或撰写文章的人编辑。我没有使用任何宝石，只是一些简单的规则。

这是我的规范：

require 'rails_helper'
require 'capybara/rspec'

describe "the authorization process", :type => :feature do
  before :each do
    @user = User.new(:id => 3, :email => 'user@example.com', :password => 'password', :password_confirmation => 'password', :username => 'Dummy User')
    @user.save
  end

  it "does not allow a registered user to edit others' articles" do
    visit '/login'
    within("#new_user") do
      fill_in 'Email', :with => 'user@example.com'
      fill_in 'Password', :with => 'password'
    end
    click_button 'Log in'
    expect(page).to have_title 'Website Name'
    expect(page).to have_content 'Signed in successfully!'

    # Seems to be working up to here

    visit section_path('mysection')

    click_link 'Some link on the page'
    expect(current_path).to eq(my_article_path(section: 'mysection', year: 2014, month: 10))
  end
end

但运行此命令会返回以下错误：

Failures:

  1) the authorization process does not allow a registered user to edit others' articles
     Failure/Error: click_link 'Some link on the page'
     NoMethodError:
       undefined method `username' for nil:NilClass
     # ./app/controllers/articles_controller.rb:38:in `show'

所以我查看 articles_controller.rb 文件并找到：

34 def show
35   if @article.nil?
36     redirect_to root_path, alert: "Oops! There are no articles matching a url ending in \"#{params[:id]}\""
37   else
38     @username = @article.user.username
39   end
40 end

我尝试使用pry来查看@username = @article.user.username行之前发生的事情。看起来好像我的@article对象存在，但是从我的测试中调用.user会返回nil，因此，调用.username也会返回nil，从而导致测试失败

这适用于开发和生产，而不是测试。我想知道如何解决这个问题？

谢谢！

Answer 1

尝试隐藏username的{{1}}，以便在调用它时不是article：

nil

使用RSpec＆amp; amp; A进行简单授权测试水豚失败了
