奇数Rails路由错误

Question

当我试图通过典型的rails表单创建一个新资源时，我得到了一个undefined method stripe_managed_accounts_path。下面是我的代码，我被搞糊涂了，弄不明白。

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/新视图

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

<%= render 'form' %>

视图/表单

<h5>inside the form</h5>

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

<% end %>

路线

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

错误

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

路线

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

它使这条线<%= form_for @stripe_managed_account do |f| %>变得更高

我对stripe_managed_accounts_path的整个代码库都很感兴趣，但它并不在任何地方。我的意见很不一致...

更新：

如果我添加该路由，它将消失？为什么它要寻找那条路线。是不是因为我给我的牧羊人起的名字，等等？

您在路由文件中的printers中嵌套了stripe_managed_accounts。如果查看一下rake routes的输出，就会发现没有通向stripe_managed_accounts_path的路径。

您可以在stripe_managed_accounts资源上使用“浅”选项，也可以调整表单以包括托管帐户所属的打印机。

#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url，并将stripe_managed_account嵌套在当前打印机中。
