在 session 中保存查询时出现 django-haystack 问题

Question

我想将用户输入保存在我的视图中，我不知道如何重新定义搜索视图，所以我这样做了：

  request.session['q']=request.GET.get('q')
  from haystack.views import SearchView
  search_view = SearchView(template = template_name)
  return search_view(request)

但我收到了这个错误：

  Traceback (most recent call last):

   File "/home/usu/mysites/gondor/local/lib/python2.7/site-packages/django/core/servers/basehttp.py", line 280, in run
    self.result = application(self.environ, self.start_response)

   File "/home/usu/mysites/gondor/local/lib/python2.7/site-packages/django/core/servers/basehttp.py", line 674, in __call__
    return self.application(environ, start_response)

   File "/home/usu/mysites/gondor/local/lib/python2.7/site-packages/django/core/handlers/wsgi.py", line 245, in __call__
    response = middleware_method(request, response)

   File "/home/usu/mysites/gondor/local/lib/python2.7/site-packages/django/contrib/sessions/middleware.py", line 36, in process_response
    request.session.save()

   File "/home/usu/mysites/gondor/local/lib/python2.7/site-packages/django/contrib/sessions/backends/db.py", line 57, in save
    session_data = self.encode(self._get_session(no_load=must_create)),

   File "/home/usu/mysites/gondor/local/lib/python2.7/site-packages/django/contrib/sessions/backends/base.py", line 88, in encode
    pickled = pickle.dumps(session_dict, pickle.HIGHEST_PROTOCOL)

   File "/usr/local/lib/python2.7/dist-packages/haystack/models.py", line 175, in __getstate__   del(ret_dict['searchsite'])

KeyError: 'searchsite'

如果我删除该行：

 request.session['q']=request.GET.get('q') 

搜索工作正常，我不知道干草堆是否有问题或我做错了什么。 谢谢。

最后我发现了问题。 在另一个视图中，我将 SerchQuerySet 的结果保存在 session 中，但是在我放入内容时并没有出现问题，但是当我将其他内容放入 session 时，问题就出现了。 这很难被发现。
