Question

从4.0.0安装Rails 4.0.2后，我的测试失败了。它适用于浏览器（开发）。 Rails 4.0.3也会出现这种情况。

20) Error:
UserFlowsTest#test_login_and_browse_site:
ActionView::Template::Error: No route matches {:id=>nil} missing required keys: [:id]
app/views/posts/_post.haml:10:in `_app_views_posts__post_haml__439576154_44475312'
app/views/posts/index.haml:1:in `_app_views_posts_index_haml__194952016_42560292'
app/controllers/posts_controller.rb:22:in `block (2 levels) in index'
app/controllers/posts_controller.rb:21:in `index'
test/integration/user_flows_test.rb:14:in `block in <class:UserFlowsTest>'

这是行user_flows_test：14

post_via_redirect "/users/login", username: users(:chloe).username, password: 'passpasspass'

这是line _post.haml：10

%a{href: user_path(post.user)}= post.user.username if post.user

文档帮助不大：http://api.rubyonrails.org/classes/ActionDispatch/Integration/RequestHelpers.html#method-i-post_via_redirect

http://guides.rubyonrails.org/testing.html#helpers-available-for-integration-tests

测试输出：

E-------------------------------

这是UsersController＃loginCreate

的结尾

  session[:user_id] = @user.id
  p "*********************************************************************** #{session[:user_id]}" 
  redirect_to root_url, :notice => "Logged in! Last seen from #{lastIP}."

这是来自Rails控制台

irb(main):009:0> p = Post.first
irb(main):011:0> app.user_path(p.user)
=> "/users/1"

这是最简单的错误

 21) Error:

    app/controllers/posts_controller.rb:21:in `index'
    test/controllers/posts_controller_test.rb:26:in `block in <class:PostsControllerTest>'

这么简单......

  test "should get index" do
    get :index                       ###### LINE 26
    assert_response :success
    assert_not_nil assigns(:posts)
  end

Answer 1

也许您的用户没有ID：

post.user.id => id

这意味着后期用户不会被保留？

Answer 2

我必须在后置灯具中将用户ID从0更改为1。那套连锁反应的变化。我还将if放在HAML中的另一行而不是行的末尾，以防万一。 HAML属性似乎在if语句之前进行了评估。

Answer 3

您的测试正在测试一个收集路由，：index，但测试显示成员路由上的错误，正如它所查找的那样：id。

您要实例化部分（app / views / posts / _post.haml），其中包含带有nil id的link_to，或者您的路径文件是问题。

安装新的Rails版本后，测试失败
