Question

我已经解决了类似问题的一些解决方案，但这些都没有奏效：

'WSGIRequest' object has no attribute 'session'

'WSGIRequest' object has no attribute 'facebook'

我正在构建一个搜索页面，如下所示：

views.py

def search(request):
    if 'query' in request.GET and request.GET['query']:
        q = request.GET['query']
        ct = Product.objects.filter(Q(name__icontains=q) | Q(desc__icontains=q) | Q(category__icontains=q))
        count = ct
        paginate = Paginator(ct, 10)
        page = request.GET.get('page')
        try:
            ct = paginate.page(page)
        except PageNotAnInteger:
            ct = paginate.page(1)
        except EmptyPage:
            ct = paginate.page(paginate.num_pages)
        dictionary = {'results': ct, 'count': count, 'query': q, }
        return render_to_response('search.html', dictionary, request)
    else:
        content = {'contentnotfound': 'Hi, you did not search for anything. Please go back or use the search box above.'}
        return render(request, 'search.html', content)

完整的追溯是：

Environment:


Request Method: GET
Request URL: http://127.0.0.1:8000/search?query=abc&submit=Submit

Exception Type: AttributeError at /search
Exception Value: 'WSGIRequest' object has no attribute 'update'

urls.py如下：

 url(r'^search$', views.search, name='search'),

我之前用另一个项目完成了同样的事情并且它完美地工作了。

Answer 1

return render_to_response('search.html', dictionary, request)

您将请求作为上下文实例传递，而您应该传递django.template.Context的实例（尽管您可能希望使用其子类RequestContext）。

Answer 2

您已在最后一行正确使用了新的render快捷方式。但是，在else子句之前的行中，您已使用较旧的render_to_response并将请求作为最后一个参数传递。您也应该使用render，请求作为第一个参数：

return render(request, 'search.html', dictionary)

'WSGIRequest'对象没有属性'update'
