在 Rails 中为 ActionController 设置操作
我刚刚发出了 [ script/generatescaffold User ] 命令来生成我的文件。所有 CRUD 页面都运行良好，这很好，现在我正在尝试创建更多页面。我在 user_controller.rb 文件中创建一个方法，如下所示：
def login
#blahblah
end
然后为视图创建 app/views/users/login.html.erb 。当我尝试通过浏览器访问它时 [http://localhost:3000/users/login]它给出了错误：
ActiveRecord::RecordNotFound（无法找到 ID=login 的用户）： app/controllers/users_controller.rb:16:在“show”中，
我将其解释为使用操作显示，并且它不将登录识别为操作。我是否缺少一些配置才能使此操作发挥作用？我对 Rails 还很陌生，所以我可能会错过一些琐碎的事情。谢谢！
更新 我尝试使用 [script/generatecontrollerUser] 然后在控制器中创建操作方法及其相应的视图。它似乎按预期工作。两者之间有何区别，以及在使用脚本/生成脚手架不可用时导致创建其他操作方法的原因是什么？
I just issued a [ script/generate scaffold User ] command to generate my files. All the CRUD pages work well so that's good and now I'm trying to create more pages. I create a method in the user_controller.rb file as follows:
def login
#blahblah
end
Then created app/views/users/login.html.erb for the view. When I tried accessing it through the browser [http://localhost:3000/users/login] it gives out the error:
ActiveRecord::RecordNotFound (Couldn't find User with ID=login):
app/controllers/users_controller.rb:16:in `show'
I'm interpreting it as using the action show and it doesn't recognize login as an action. Am I missing some configuration for this action to work? I'm quite new to Rails so I might be missing something trivial. Thanks!
UPDATE
I tried using [script/generate controller User] then created action methods in the controller and it's corresponding views. It seems to work as predicted. What makes the difference between the two and what causes the creation of additional action methods when using script/generate scaffold not available?

您需要打开路由文件并将集合映射添加到用户路由。在您的情况下，该行可能会显示
map.resources :users, :collection => {：登录=> :get }查看 http://guides.rubyonrails.org/routing.html 有关铁路路线的更多信息
You need to open your routes file and add a collection mapping to the users route. In your case, the line might read
map.resources :users, :collection => { :login => :get }Check out http://guides.rubyonrails.org/routing.html for more info on Rails routes
