Rails 4 fixtures没有生成ID(Hartl教程9.6.2)

我正在根据Hartl教程创建一个应用程序,并且我坚持第二个练习:

  

为所有布局链接编写集成测试,包括登录和未登录用户的正确行为。提示:使用log_in_as帮助程序添加到代码清单5.25中的测试。

我测试中的代码是

require 'test_helper'

class SiteLayoutTest < ActionDispatch::IntegrationTest

def setup
   @user = users(:test)
end

test 'layout links' do
   get root_path
   assert_template 'static_pages/home'
   assert_select "a[href=?]", root_path, count: 2
   assert_select "a[href=?]", help_path
   assert_select "a[href=?]", about_path
   assert_select "a[href=?]", contact_path
   assert_select "a[href=?]", login_path
   get signup_path
   assert_select "title", full_title("Signup")
   log_in_as @user
   get root_path
   assert_select "a[href=?]", users_path, text: "Users"
   assert_select "a[href=?]", user_path
   assert_select "a[href=?]", edit_user_path(@user)
   assert_select "a[href=?]", logout_path

端 端

这是我正在使用的灯具:

test:
 name: Test Name
 derby_name: Test Derby Name
 email: test@rdsg.com
 password_digest: <%= User.digest('password') %>
 admin: true

这是我在进行测试时遇到的错误:

ERROR["test_layout_links", SiteLayoutTest, 2015-07-07 21:08:39 +0000]                                                              
 test_layout_links#SiteLayoutTest (1436303319.87s)                                                                                 
ActionController::UrlGenerationError:         ActionController::UrlGenerationError: No route matches {:action=>"show", :controller=
>"users"} missing required keys: [:id]                                                                                             
            test/integration/site_layout_test.rb:22:in `block in <class:SiteLayoutTest>'                                           
        test/integration/site_layout_test.rb:22:in `block in <class:SiteLayoutTest>' 

在我看来,我的灯具由于某种原因没有生成ID,即使我手动运行测试时我也能正常访问站点导航URL,当我运行rails console --sandbox并创建一个新用户时对象它生成一个ID。我已经尝试过寻找答案,但没有运气(我已经坚持了好几天了!)。

我正在使用带有Rails 4.2.0的Codio IDE和带有Minitest的Ruby 2.1.5作为测试套件。

编辑:作为参考,这是我的log_in_as助手:

# Logs in a test user
def log_in_as(user, options = {})
    password = options[:password] || 'password'
    remember_me = options[:remember_me] || '1'
    if integration_test?
        post login_path, session: { email: user.email,
            password: password, 
            remember_me: remember_me }
    else
        session[:user_id] = user.id
    end
end

以防将来帮助任何人:)

谢谢,Baldrick,在下面解决它!

答案 0 :(得分:1)

错误消息的重要部分是ActionController::UrlGenerationError: No route matches {:action=>"show", :controller=>"users"} missing required keys: [:id]。方法user_path需要一个用户(它是显示给定用户的路径),所以它应该是

assert_select "a[href=?]", user_path(@user)
