问题描述
我正在像这样链接到 Sessions 控制器的销毁操作:
I'm linking to the destroy action for the Sessions controller like this:
<%= link_to "Sign out", session_path, method: :delete %>
Routes.rb:
resources :sessions, only: [:new, :create, :destroy]
Rails 抱怨上面的链接:
Rails complains about the link above:
没有路由匹配 {:action=>"destroy", :controller=>"sessions"} 缺少必需的键:[:id]
当没有为链接提供对象 ID 时，如何链接到销毁操作并在 Rails 中保留 REST/资源方法?
How do I link to the destroy action and keeping the REST/resource methodology in Rails when there's no object ID to provide for the link?
推荐答案
最好将到会话控制器的路由视为单一资源
It is best to treat the routes to your sessions controller as a singular resource
routes.rb
resource :sessions
文档:http://guides.rubyonrails.org/routing.html#singular-资源
这将为您提供一条无需 ID 即可使用的路线
This will give you a route that you can use without ID's
删除/sessions 会话#destroy
DELETE /sessions sessions#destroy
这篇关于会话路由#destroy action的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！
