Question

我试过

= form_for [@user, @subscription], html: {id: 'subscription_form'} do |f|

（ActionController :: UnknownFormat）和

= form_for @subscription, html: {id: 'subscription_form'} do |f|

（未定义的方法`subscription_path'）但它不起作用。但这很有效：

= form_for @subscription, url: user_subscription_path(@user), html: {id: 'subscription_form'} do |f|

我的路线：

  resources :users do
    resource :subscription, only: [:edit, :new, :create, :update, :destroy]

和

C:\Users\Chloe\workspace\>rake routes | grep subscription
   new_user_subscription GET    /users/:user_id/subscription/new(.:format)  subscriptions#new
  edit_user_subscription GET    /users/:user_id/subscription/edit(.:format) subscriptions#edit
       user_subscription PATCH  /users/:user_id/subscription(.:format)      subscriptions#update
                         PUT    /users/:user_id/subscription(.:format)      subscriptions#update
                         DELETE /users/:user_id/subscription(.:format)      subscriptions#destroy
                         POST   /users/:user_id/subscription(.:format)      subscriptions#create

user.rb

class User < ApplicationRecord
  has_one :subscription

我在这种情况的文档中没有看到任何内容：http://api.rubyonrails.org/classes/ActionView/Helpers/FormHelper.html#method-i-form_for

如何在没有`url：`的情况下使用`form_for`资源导向的样式？
