使用Ruby on Rails制作sitemap.xml 4

Question

我正在尝试为我的Ruby on Rails 4应用程序制作一个站点地图.我会使用像这样的dynamic_sitemaps的gem,但是我不能和Heroku一起使用所以我环顾四周找到了这个教程:http://meghagulati.com/2013/12/05/sitemap-xml-on-heroku-with- ruby-on-rails /制作我自己的(稍加更改)但是当我访问myapp.com/sitemap.xml时我收到此错误,希望有人可以帮我找到错误.

ActionController::UnknownFormat in SitemapsController#index ActionController::UnknownFormat Extracted source (around line #7): respond_to do |format|

#app/controllers/sitemaps_controller.rb
class SitemapsController < ApplicationController
  def index
    @static_pages = [root_url]
    @movies = Movie.all
    respond_to do |format|
      format.xml
    end
    @series = Series.all
    respond_to do |format|
      format.xml
    end
  end
end

#app/views/sitemaps/index.xml.builder

#config/routes.rb
resources :sitemaps, :only => :index
get "sitemap.xml" => "sitemaps#index", format: :xml, as: :sitemap

Answer 1

首先,您只能调用一次respond_to,因此您需要更改控制器方法,例如:

class SitemapsController < ApplicationController
  def index
    @static_pages = [root_url]

    @movies = Movie.all
    @series = Series.all

    respond_to do |format|
      format.xml
    end
  end
end

当您访问以下URL时,此更改应在浏览器中呈现XML文件:

http://lvh.me:3000/sitemaps.xml

此外,您需要更改路由规范并使用字符串作为格式而不是符号,即将:xml更改为"xml":

  get "sitemap.xml" => "sitemaps#index", :format => "xml", :as => :sitemap

访问以下URL时,您应该在浏览器中看到相同的XML文件:

http://lvh.me:3000/sitemap.xml

(lvh.me解析为localhost)
