【问题描述】：

我正在尝试通过我的 Django 1.11.4 项目中的 jquery 插件 Select2 实现实时搜索。运行 Python 3.6。当我在文本框中输入时，服务器似乎无法处理请求的数量并关闭，随后出现一系列错误。 我花了几个小时关注SOSO(more)、Google、etc 上的几个线程，但没有一个有效的解决方案。我以为是 python 版本问题，但我已经从 2.7 升级到 3.6 并且仍然有它。任何帮助都会非常感谢！

这是由 ajax 调用调用的视图：

  def directory_search(request):
      # Query text from search bar
      query = request.GET.get('q', None)
      if query:

          # Searches the DB for matching value
          customers = Customer.objects.filter(
              Q(name__icontains= query)|
              Q(contract_account__icontains= query)|
              Q(address__icontains= query)|
              Q(address__icontains= query)|
              Q(email__icontains= query)
              ).distinct()
          # Turns queryset into dict
          customers = customers.values("contract_account","name")
          # Turns dict into list
          customers_list = list(customers)

          return JsonResponse(customers_list, safe=False)
      else:
          return JsonResponse(data='success': False,'errors': 'No mathing items found')

这是 Select2 插件的 js/ajax 调用：

  $(".customer-search-bar").select2(
    ajax:
      dataType: 'json',
      type: 'GET',
      url:"% url 'portal:directory_search' %",
      data: function (params) 
          var queryParameters = 
              q: params.term
          
          return queryParameters;
      ,
      processResults: function (data) 
          return 
              results: $.map(data, function (item) 
                  return 
                      text: item.name,
                      id: item.contract_account
                  
              )
          ;
      
    ,
    escapeMarkup: function (markup)  return markup; ,
    minimumInputLength: 1,
    templateResult: formatRepo,
    templateSelection: formatRepoSelection,
    language:  errorLoading:function() return "Searching..." 
  );

错误：（我只是将它们分开以使其更清晰，但它们按呈现的顺序发生）

【参考方案1】：

它似乎是 python 2.7 已知的错误，也许它仍然存在于 python 3.6：

https://bugs.python.org/issue14574

我在 django 中遇到了类似的问题，也在运行 python 3.6 TypeError: 'NoneType' object is not subscriptable followed by AttributeError: 'NoneType' object has no attribute 'split'

编辑

这似乎是 chrome 上的错误。我没有想到，因为我使用的是 Opera，但 Opera 也使用了 Chromium。在 Internet Explorer 中没有显示错误。
