Question

在尝试通过典型的rails表单创建新资源时，我得到undefined method stripe_managed_accounts_path。下面是我的代码，我傻眼了，无法弄清楚。

控制器

class StripeManagedAccountsController < ApplicationController
  before_action :authenticate_printer!

  def new
    @stripe_managed_account = StripeManagedAccount.new(printer_id: current_printer.id)
  end
end

模型

class StripeManagedAccount < ActiveRecord::Base
    belongs_to :printer
end

视图/新

<h1>Create New Stripe Managed Account</h1>

<%= render 'form' %>

查看/形式

<h5>inside the form</h5>

<%= form_for @stripe_managed_account do |f| %>

<% end %>

路由

resources :printers, only: [:show, :edit, :update] do
    resources :stripe_managed_accounts
end

错误

`undefined method 'stripe_managed_accounts_path' for #<#<Class:0x007fc627d342b8>:0x007fc62b36e108>`

路由

printer_stripe_managed_accounts GET    /printers/:printer_id/stripe_managed_accounts(.:format)          stripe_managed_accounts#index
                                    POST   /printers/:printer_id/stripe_managed_accounts(.:format)          stripe_managed_accounts#create
 new_printer_stripe_managed_account GET    /printers/:printer_id/stripe_managed_accounts/new(.:format)      stripe_managed_accounts#new
edit_printer_stripe_managed_account GET    /printers/:printer_id/stripe_managed_accounts/:id/edit(.:format) stripe_managed_accounts#edit
     printer_stripe_managed_account GET    /printers/:printer_id/stripe_managed_accounts/:id(.:format)      stripe_managed_accounts#show
                                    PATCH  /printers/:printer_id/stripe_managed_accounts/:id(.:format)      stripe_managed_accounts#update
                                    PUT    /printers/:printer_id/stripe_managed_accounts/:id(.:format)      stripe_managed_accounts#update
                                    DELETE /printers/:printer_id/stripe_managed_accounts/:id(.:format)      stripe_managed_accounts#destroy

并且它正在引用这一行<%= form_for @stripe_managed_account do |f| %>

我已经为stripe_managed_accounts_path编写了整个代码库，但它不在哪里。我很有可能...

UPDATE :::

如果我添加该路线它会消失???为什么要寻找那条路线。是因为我如何命名我的fodlers等等？

您在stripe_managed_accounts内将printers嵌套在路线文件中。如果您查看rake routes的输出，可以看到stripe_managed_accounts_path没有路径。

您可以使用stripe_managed_accounts资源上的浅选项，也可以调整表单以包含管理帐户所属的打印机。

#controller
class StripeManagedAccountsController < ApplicationController
  before_action :authenticate_printer!

  def new
    @stripe_managed_account = current_printer.build_stripe_managed_account
  end

  def create
    current_printer.stripe_managed_accounts.create stripe_managed_account_params
    # handle response
  end

  def stripe_managed_account_params
    params.require(:stripe_managed_account).permit([list of attributes])
  end
end

#form
<h5>inside the form</h5>

<%= form_for [current_printer, @stripe_managed_account] do |f| %>

<% end %>

这将生成正确的网址，将stripe_managed_account嵌套在当前打印机内。

对于has_one关联参考http://guides.rubyonrails.org/association_basics.html#has-one-association-reference
