Question

我试图通过我的Django 1.11.4项目中的jquery插件Select2实现实时搜索。运行Python 3.6。当我输入文本框时，服务器似乎无法处理请求数量并关闭，然后是这些系列错误。我已经在SO SO(more)，Google，etc上花了几个小时跟踪了几个帖子，但没有一个有可行的解决方案。我认为这是一个python版本问题，但我已经从2.7升级到3.6并且仍然拥有它。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:(我只是将它们拆开以使其更清晰，但它们出现在呈现的顺序中）

Answer 1

它似乎是一个已知的python 2.7 bug，也许它仍然存在于python 3.6：

https://bugs.python.org/issue14574

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

修改

Chrome上似乎是一个错误。它并没有找到我，因为我使用的是Opera，但是Opera也使用了铬。在Internet Explorer中，错误没有显示。
