Question

我正在使用Python和Django创建一个电影网络应用程序，它有一个搜索功能，它给我一些我不太懂的错误。

ERROR

movies / 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?
    })

我很明白错误是我创建2列表的段的地方，但那里没有会话。我从下面的列表页面中调用它：

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,
        })

Answer 1

通过使用名为list的视图，您遮蔽了内置的list 。重命名你的观点。

'set'对象没有属性'session'
