Ruby on Rails 视图不呈现（加载空白）-解网

问：

我正在努力在 Ruby on Rails 中实现一个 RSS 提要来联合房地产列表（首先是 Zillow，然后是其他人）。目前，我正在努力加载视图。

我试图搜索 SO 以查看另一个问题是否接近或答案有效并出现空白。因此，如果这是多余的，我深表歉意，但这是无意的。

Ruby on Rails 版本：7.0.4

路线：

require 'sidekiq/web'
require 'sidekiq/cron/web'
Rails.application.routes.draw do
  if ENV['ENABLE_INTERNAL_ROUTES'] || Rails.env.development?
    mount Sidekiq::Web => '/sidekiq'
    mount RailsAdmin::Engine => '/admin', as: 'rails_admin'
  end

  mount GraphiQL::Rails::Engine, at: "/graphiql", graphql_path: "/graphql" if ENV['APP_ENV'] != 'production'
  post "/graphql", to: "graphql#execute"
  # Define your application routes per the DSL in https://guides.rubyonrails.org/routing.html

  # Defines the root path route ("/")
  # root "articles#index"

  mount Rswag::Ui::Engine => '/api-docs'
  mount Rswag::Api::Engine => '/api-docs'

  get '/feeds/zillow', to: 'feeds#zillow'
end

控制器：饲料控制器app/controllers/feeds_controller.rb

class FeedsController < ApplicationController
  def zillow
    @listings = Listing.where(syndication_type: 'SYNDICATION_ON')
    respond_to do |format|
      format.html { render "feeds/zillow" }
      format.rss { render layout: false }
    end
  end
end

应用控制器app/controllers/application_controller.rb

class ApplicationController < ActionController::API
  include ActionController::MimeResponds
end

视图： zillow.html.erbapp/views/feeds/zillow.html.erb

<!DOCTYPE html>
<html>
<head>
  <title>Temporary for checking</title>
</head>
<body>
  <h1>Do we even exist?</h1>
</body>
</html>

zillow.rss.builderapp/views/feeds/zillow.rss.builder

# app/views/posts/index.xml.builder
xml.instruct! :xml, version: "1.0"
xml.rss version: "2.0" do
  xml.channel do
    xml.title "RSS Rails"
    xml.description "Some random description. We will expand later"
  end
end

请求：curl -i http://localhost:3000/feeds/zillow.rss

搜索告诉我，返回的单个表示响应结束。值得注意的是，这会下载一个完全为空的文件，而不是提供空白页。%

如果我从 FeedsController 中删除导致请求不呈现布局的指令，我会得到以下内容：.rss

请求：curl -i http://localhost:3000/feeds/zillow.rss

我已确认有正在返回的本地种子数据。我显然错过了一些东西，但我不知道是什么。

提前感谢您提供的任何帮助！
