ruby-on-rails - Rails 调用已删除的控制器

问题描述

这里的基本 Rails 问题：我有一个名为的控制器方法fetch_headlines，我一直在尝试调试。我对控制器进行了更改，但它们没有反映在输出中。这让我觉得 Rails 没有正确调用fetch_headlines. 观察下面的控制台。

Puma starting in single mode...

* Min threads: 5, max threads: 5
* Environment: development
* Listening on tcp://localhost:3000
Use Ctrl-C to stop

  Rendered entries/show.html.erb within layouts/application (2.8ms)
Completed 200 OK in 482ms (Views: 476.3ms | ActiveRecord: 0.0ms)

此外，如果我请求不存在的方法，Rails 会呈现相同的行为，例如：qwertyqwerty. 我希望 Rails 会抛出错误。

Started GET "/entries/qwertyqwerty" for ::1 at 2020-01-09 05:59:13 -0500

  Parameters: {"id"=>"qwertyqwerty"}

这是我的路线.rb

get 'fetch_headlines', to: 'entries#fetch_headlines'
  resources :entries
  resources :keywords
  resources :networks

谢谢。

解决方案

你放get 'fetch_headlines', to: 'entries#fetch_headlines'，它创建/fetch_headlines而不是/entries/fetch_headlines路由。你需要的是这样的：

get 'entries/fetch_headlines', to 'entries#fetch_headlines'

甚至更好

resources :entries do
  collection do
    get :fetch_headlines
  end
end
