Question

受this博客帖子的启发，我试图通过将搜索参数保存到会话中来创建处理配置文件搜索的视图，以便可以通过分页保留查询。

以下是观点：

def profile_search(request):
    args = {}
    qs=[]
    if not request.method == 'POST':        
        if 'search-profiles-post' in request.session: 
            request.POST = request.session['search-profiles-post'] 
            request.method = 'POST' 


    if request.method == "POST":
        form = AdvancedSearchForm(request.POST)
        request.session['search-profiles-post'] = request.POST


        if form.is_valid():
            cd = form.cleaned_data

            s_country=cd['country']
            s_province=cd['province']
            s_city = cd['city']

        if s_city: qs.append( Q(city__in=s_city))
            if s_country: qs.append(Q(country__icontains = s_country))
            if s_province: qs.append( Q(province__icontains=s_province))    



            f = None
            for q in qs:
                if f is None: 
                    f=q                                  
                else: f &=q
            print f

            if f is not None:
                profiles = UserProfile.objects.filter(f).order_by('-created_at') 

        else:
            form = AdvancedSearchForm()
            profiles = UserProfile.objects.all().order_by('-created_at') 

    paginator = Paginator(profiles,12)

    page= request.GET.get('page')
    try:
        results = paginator.page(page)
    except PageNotAnInteger:
        results = paginator.page(1)  

    except EmptyPage:
            results = paginator.page(paginator.num_pages)        

    args.update(csrf(request))    
    args['form'] = form  
    args['results'] = results
    return render_to_response('userprofile/advanced_search.html', args,
                              context_instance=RequestContext(request))

以下是表格：

<form action="/search/" method="post">{% csrf_token %}

          <ul class="list-unstyled">

            <li><h3>Country</h3></li>
            <li>{{form.country}}</li><br> 
            <h4>Province</h4>
            <li>{{form.province}}</li>
              <h4>City</h4>
            <li>{{form.city}}</li>


          </ul>

<input  type="submit" name="submit"  value="search" />

 </form>
     Search Results:
{% for p in results %}

            <div">
                  <div>
                      <br>
                       <strong><a href="/profile/{{p.username}}" >{{p.username}}</a></strong>
                         {{p.country}} <br>
                         {{p.province}} <br>
                         {{p.city}} <br>

                     </div>
                  </div>
{% endfor %}



<div>
    <div class="pagination">
      {% if results.has_previous %}
          <a href="?page={{ results.previous_page_number }}"> << Prev </a>&nbsp;&nbsp
      {% endif %}

       {% if results.has_next %}
          <a href="?page={{ results.next_page_number }}"> Next >> </a>
      {% endif %}
    </div>
  </div>

</div>

和urls.py

url(r'^search/', 'userprofile.views.profile_search'),

这是我得到的神秘错误：

Traceback:

    File "/home/supermario/.djenv/local/lib/python2.7/site-packages/django/core/handlers/base.py" in get_response
      204.                 response = middleware_method(request, response)
    File "/home/supermario/.djenv/local/lib/python2.7/site-packages/debug_toolbar/middleware.py" in process_response
      89.             new_response = panel.process_response(request, response)
    File "/home/supermario/.djenv/local/lib/python2.7/site-packages/debug_toolbar/panels/request.py" in process_response
      31.             'post': [(k, request.POST.getlist(k)) for k in sorted(request.POST)],

    Exception Type: AttributeError at /search/
    Exception Value: 'dict' object has no attribute 'getlist'

我有一段时间的股票，所以非常感谢你的提示。

request.POST应该是类似dict的QueryDict，而不是简单的python dict：

from django.http import QueryDict

request.POST = QueryDict('').copy()
request.POST.update(request.session['search-profiles-post'])

Django'dict'对象没有属性'getlist'
