我正在运行一个 React 应用程序。

当我通过路由（单击按钮或链接）进入页面时，页面工作正常，但是当我重新加载页面时，它崩溃了。我看不到错误在哪里，控制台和源显示空白，这是服务器消息控制台消息。

我使用ruby驱动程序从mongodb中找到文档，将它们收集到数组中并对其进行迭代，以更新与以下代码中相同的文档：

crawlarray = @@mongoclient[:crawlarray].find({searchresults:[]},:timeout => false).limit(500)
crawlarray.each do |elm|
    finalsearchstring = elm['searchstring'] 
    if elm["searchresults"].blank?
        ap "SEARCHING: #{finalsearchstring}"
        results = searchG(finalsearchstring) 
        elm["searchresults"] = results
        @@mongoclient[:crawlarray].update_one({"_id" => elm['_id']}, elm)
    else
        ap "ALREADY SEARCHED: #{finalsearchstring}"
    end
end

有90K条记录，但是正如您看到的，我得到500条记录才不会出错。每次经过约150次迭代后，我都会收到此错误；

每次加载曾经可以工作的反应本机页面时，我都会遇到以下错误。我删除了所有 100% 宽度，实际上我尝试删除所有宽度但没有成功。也尝试删除所有样式。将 expo React 更新为 sdk 38，但没有成功。代码中没有宽度被划分。尝试删除下面列出的外部组件，但也没有成功。任何人都知道出了什么问题吗？

我正在使用带有Rails和Mongoid的Select2,我在服务器端有Sunspot Solr来进行搜索.我正在尝试的是通过solr从mongo过滤数据,通过ajax请求获取数据并根据父子层次结构对结果进行分组.我无法弄清楚的是当我搜索一个孩子时,如果有多个子结果,则父类别会多次出现.请阅读以下内容了解更多信息:

这是我在Mongo DB中的数据

{"_ id":ObjectId("5209eb465a721ae827c661de"),"title":"BinaKanalizasyonTesisatı","parent":"SuTesisatçılığı","path":"sutesitati/kanalizasyon"}

{"_ id":ObjectId("5209eb465a721ae827c661df"),"title":"Daire TemizSuTesisatı","parent":"SuTesisatçılığı","path":"sutesisati/temizsu"}

{"_ id":ObjectId("5209eb465a721ae827c661e0"),"title":"Musluk Tamiri","parent":"SuTesisatçılığı","path":"sutesitati/musluktamiri"}

这是我的Rails模型

class Category
  include Mongoid::Document
  include Sunspot::Mongoid2

  searchable do
    text :title 
  end

  field :title, :as => :title_textp
  field :parent
  field :path  
end

这是我的Rails控制器

class CategoriesController < ApplicationController
  respond_to :html, :json

  def list_styles 
      search = Category.search do
        fulltext params[:q]
      end
      search = Category.search { keywords params[:q]; paginate :page => params[:page], :per_page => params[:page_limit] }
      @results = search.results
      @total_lines = search.total
      @categories = @results    
     respond_with @categories 
  end 

end

这是我的Haml View …
