路由错误|没有匹配的路由[POST] "/subscriptions/create“

Question

我是Ruby on Rails的新手，我正在开发一个包含表单的应用程序，该表单用于创建新的被提名人(将其存储在数据库中)。我发现表单的以下指令有问题：

<%= form_for :subscription, :url => {:controller => "subscriptions", :action => "create"} do |f| %>

这是错误：

Routing Error
No route matches [POST] "/subscriptions/create"

Answer 1

您可以从下面的代码行中看到：

Prefix Verb       URI Pattern                               Controller#Action
subscriptions_create GET        /subscriptions/create(.:format)           subscriptions#create

您已经获得了subscriptions_create的路由，但它需要是POST而不是GET。只需将配置文件夹中routes.rb文件中的此路由更新为POST而不是GET即可。

Answer 2

正如您从此行subscriptions_create GET /subscriptions/create(.:format)中看到的，该路由仅在使用GET HTTP方法时可用。

您需要将订阅的routes.rb文件更改为接受POST而不是GET。最简单的方法是添加resources :subscriptions，这将为资源添加所有标准的CRUD路由。
