ruby-on-rails - Rspec redirect_to 显示操作

Question

我正在学习 Rails 并且遇到了 Rspec 的问题。我对 Controller 进行了以下测试:

describe PostsController, "creating a new post" do
  it "should redirect and show the post" do
    Post.stub!(:save).and_return(true)
    post "create"
    response.should redirect_to :action => "show"
  end
end

当我运行此测试时，出现以下故障:

PostsController creating a new post should redirect and show the post
Failure/Error: response.should redirect_to :action => "show"
ActionController::RoutingError:
  No route matches {:action=>"show", :controller=>"posts"}
  # ./spec/controllers/posts_controller_spec.rb:8:in `block (2 levels) in <top       (required)>'

然而，当我检查我的路线时，我看到我的帖子 Controller 显示 Action :

post GET    /posts/:id(.:format)      {:action=>"show", :controller=>"posts"}

我可能遗漏了一些非常简单但很难找到的东西。

谢谢。

您忘记了 id。

我经常写

response.should redirect_to(post_path(assigns[:post])
