在Home＃new中与shopify -NoMethodError在Rails中与无表模型作斗争

Question

我正在为shopify创建一个简单的应用程序，用户在该应用程序中输入用户的电子邮件地址，然后使用此电子邮件通过API将shopify商店订单历史记录发送到该地址。

由于无需存储电子邮件，因此我创建了一个无表模型，作为Railscast第193、219条中的教程，但出现此错误

“ Home＃new中的NoMethodError” 未定义的方法“ emails_path”，用于＃<＃：0x00005574bfa8a258> 你的意思是？ image_path

而且我不知道如何解决它，因为我仍然对RoR还是很熟悉，所以我也会为该错误添加一个屏幕截图，这是我的文件

home_controller.rb

class HomeController < ShopifyApp::AuthenticatedController
  # solve the  invalid authenticaty token problem by adding this security 
  # protect_from_forgery is included by default in application controller but we have to
  # add it here manually
  protect_from_forgery

  def index
    @products = ShopifyAPI::Product.find(:all, params: { limit: 10 })
    @orders = ShopifyAPI::Order.find(:all, params: { limit: 10 })
    @webhooks = ShopifyAPI::Webhook.find(:all)
  end

  def new
    @email = Email.new
  end

  def create
    @email = Email.new(params[:themail])
    #byebug
    if @email.valid?
        redirect_to '/ordertocsv'
    else
        redirect_to root_url
    end
  end

end

models / email.rb

class Email
  include ActiveModel::Validations
  include ActiveModel::Conversion
  extend ActiveModel::Naming

  attr_accessor :themail

  validates_presence_of :themail
  validates_length_of :themail, :maximum => 500

  def persisted?
    false
  end

end

views / home / new.html.erb

<% form_for @email do |f| %>
  <%= f.error_messages %>
  <p>
    <%= f.label :themail %><br />
    <%= f.email_field :themail, required: true %>
  </p>
  <p>
    <%= f.submit "Send Email" %>
  </p>
<% end %>

routes.rb

Rails.application.routes.draw do
  root to: 'home#index'
  get "/ordertocsv", to: "home#new"
  post "/ordertocsv", to: "home#create"
  mount ShopifyApp::Engine, at: '/'
