python - 如何结合引导分页器和选择过滤表？

问题描述

我目前在桌子上使用分页器。我想添加一个选择来过滤表格，但我不管理如何在不丢失选择的情况下浏览页面。

当前（请参见下面的代码）当我通过单击上一个或下一个进行导航时，使用的选项会丢失，并且会显示所有数据。

我必须更改“其他”条件以考虑所选选项。我正在考虑使用全局变量来存储在变量中选择的选项，但它可能会产生副作用，因此不推荐......

视图.py

@login_required
def index(request):

    # data sent (click on 'search' button or option selected)
    if request.POST:
        # data from select
        selection = request.POST.get('selection', False)
        # data from search
        ide = request.POST.get('ide', False)

        # search
        if ide == "":
            paginator = Paginator(Preinclusion.objects.all(), 5)
            preincluded = paginator.page(1)
        else:
            paginator = Paginator(Preinclusion.objects.filter(pat_num__startswith = ide),5)
            preincluded = paginator.page(1)

        # select
        if selection == 'Randomized':
            print('Randomized')
            paginator = Paginator([patient for patient in Preinclusion.objects.all() if patient.is_randomized], 5)
            preincluded = paginator.page(1)

        elif selection == 'Not randomized':
            print('Not randomized')
            paginator = Paginator([patient for patient in Preinclusion.objects.all() if not patient.is_randomized], 5)
            preincluded = paginator.page(1)

        elif selection == 'All patients':
            print('All patients')
            paginator = Paginator(Preinclusion.objects.all(), 5)
            preincluded = paginator.page(1)

        if not preincluded:
            liste_existe = False # non utilisé dans le template

    else:

        # first index visited
        paginator = Paginator(Preinclusion.objects.all(), 5)
        page = request.GET.get('page')

        try:
            preincluded = paginator.page(page)
        except PageNotAnInteger:
            preincluded = paginator.page(1)
        except EmptyPage:
            preincluded = paginator.page(paginator.num_pages)

    return render(request, 'randomization/index.html', {'preincluded': preincluded})

我想store为上一个/下一个导航选择选项。
