我的 github 获取代码源

在浏览器 AJAX 工作正常，但测试是红色的。:(

我对编程、Rails 和 Stackowerflow 还是很陌生。请帮我解决这个问题。:3

在 RailsTutorial（使用 Rails 3.2）第 11 章的相同 Ajax 部分之后，我遇到了完全相同的问题。我认为 Michael de Silva 是对的，因为不幸的是 xhr 在这里与 RSpec 混合在一起。

无论如何，为了完整起见，我决定（我几乎完成了教程） - 我打算让 xhr 以某种方式在这里工作。我认为 Mike Hartl 的清单 11.37 应该使用 ActionDispatcher::Integration::RequestHelpers 方法 xhr，如 http://api.rubyonrails.org/classes/ActionDispatch/Integration/RequestHelpers.html#method-i-xhr

而不是 ActionController::TestCase::Behavior 方法 xhr，如 http://api.rubyonrails.org/classes/ActionController/TestCase/Behavior.html#method-i-xhr

所以我用它们命名的路由替换了对actions :create 和:destroy 的引用，并且代码清单11.37 中的测试示例变成了绿色。原本的

expect do
  xhr :post, :create, relationship: { followed_id: other_user.id }
end.to change(Relationship, :count).by(1)

变成，

expect do
  xhr :post, relationships_path, relationship: { followed_id: other_user.id }
end.to change(Relationship, :count).by(1)

并且，原来的

expect do
  xhr :delete, :destroy, id: relationship.id
end.to change(Relationship, :count).by(-1)

变成，

expect do
  xhr :delete, relationship_path(relationship.id), id: relationship.id
end.to change(Relationship, :count).by(-1)

看看这是否有帮助： RSpec test destroy method (Rails Tutorial 3.2 Ch. 9, Ex. 10)

我还会在上面的链接中进一步阅读；您应该最大限度地利用 Capybara，而不是将 rspec 与 Rails 为Action*::TestCase. 改为这样做

您可以使用 capybara 的page.execute_script（但您必须为此示例启用 javascript :js => true）
