问题描述
为什么我不能让我的button_to指定控制器的create动作而不是show
Why can I not get my button_to to specify the create action of my controller rather than show
我已经尝试了无数次添加：action => create以及button_to参数中的其他内容
I have tried numerous times to add :action => "create" and other such things to the button_to parameters
<%= button_to "subscribe", subscription_path(feed_url: @feed.feed_url)%>
我是否需要在route.rb中指定创建路径？
do I need to specify a create route in my routes.rb? if so how should I go about that?
使用该行的方式时，在加载时出现此错误：
When used the way that line is, I get this error on load:
路由错误
没有路由匹配{：action => show，：controller => subscriptions，：feed_url => http：// foo.com/rss}
No route matches {:action=>"show", :controller=>"subscriptions", :feed_url=>"http://foo.com/rss"}
我将其作为订阅的唯一参考。
in routes.rb I have this as the only reference to subscriptions.
resource :subscriptions
推荐答案
您需要使用 subscripton s _path ，而不是 subscription_path 。
You need to use subscriptons_path, not subscription_path.
subscription_path 用于显示特定的订阅。
subscriptions_path 用于显示所有订阅（通过GET请求）或创建新订阅（通过POST请求）。
subscription_path is for showing a specific subscription.subscriptions_path is for showing all subscriptions (via a GET request) or creating new subscriptions (via a POST request).
<%= button_to "subscribe", subscriptions_path(feed_url: @feed.feed_url, :method => :post)%>
