'set'object has no attribute'session'

Question

我正在用Python和Django创建一个电影网络应用程序，它有一个搜索功能，它给了我一些我不太了解的错误。

ERROR

[16/May/2016 16:22:05] ERROR [django.request:284] Internal Server Error: /movies/search/

AttributeError: 'set' object has no attribute 'session' 

电影/ views.py搜索功能

def search(request, keyword='', resolution='all'): 
    if request.POST: 
     request.session['nextpage'] = reverse('movies:search', kwargs={ 
      'keyword': request.POST.get('keyword'), 
      'resolution': request.POST.get('resolution')}) 
    else: 
     request.session['nextpage'] = reverse('movies:search', kwargs={ 
      'keyword': keyword, 
      'resolution': resolution}) 

    searchresult = [] 
    resolutions = Resolution.objects.all().order_by('name') 

    if request.POST: 
     keyword = request.POST.get('keyword') 
     resolutionid = request.POST.get('resolution') 
    else: 
     keyword = keyword 
     resolutionid = resolution 

    filteredkeyword = [] 
    filteredresolution = [] 
    filteredall = Movie.objects.all() 

    if keyword != '': 
     filteredkeyword = Movie.objects.filter(title_en__icontains=keyword) 
    else: 
     filteredkeyword = filteredall 

    if resolutionid != 'all': 
     storedmovies = StoredMovie.objects.filter(resolution__id=int(resolutionid)) 
     for stored in storedmovies: 
      filteredresolution.append(stored.movie) 
    else: 
     filteredresolution = filteredall 

    searchresult = list(
     set(filteredkeyword) & 
     set(filteredresolution) 
    ) 

    return render(request, 'movies/search.html', { 
     'movies': searchresult, 
     'lang': lang, 
     'countresult': len(searchresult) #ez mire is? 
    }) 

我种-的理解错误就是我创建了2列出的段，但没有会话那里。 我把它从列表页面，如下所示：

def list(request, page=1): 
    request.session['nextpage'] = reverse('movies:list', kwargs={'page': page}) 

    lang = request.session.get('language', 'failed') 
    if lang == 'failed' or lang not in supported_langs : 
     return redirect('movies:language') 

    movie_list = Movie.objects.all().order_by('-added') 
    resolutions = Resolution.objects.all().order_by('name') 
    paginator = Paginator(movie_list, 20) # Show 20 contacts per page 

    #page = request.GET.get('page') 
    try: 
     movies = paginator.page(page) 
    except PageNotAnInteger: 
     # If page is not an integer, deliver first page. 
     movies = paginator.page(1) 
    except EmptyPage: 
     # If page is out of range (e.g. 9999), deliver last page of results. 
     movies = paginator.page(paginator.num_pages) 

    return render(request, 'movies/list.html', { 
     'movies': movies, 
     'lang': lang, 
     'resolutions': resolutions, 
     })

由于具有所谓list视图，你是阴影内置list。重命名您的视图。
