Question

如何在每个第三个帖子中放一个横幅

def all_ads(request):
all_ads = CreateNewAdvert.objects.filter(is_active=True)
all_ads_list = list()
banner = Banners.objects.all()
counter = 0
for i in all_ads:
    if len(all_ads_list) % 3 == 0:
            all_ads_list.append(i)
            all_ads_list = list()
            all_ads_list.append(banner[counter])
    print i
paginator = Paginator(all_ads, 10)  # Show 25 contacts per page
page = request.GET.get('page')
try:
    all_ads_paginated = paginator.page(page)
except PageNotAnInteger:
    # If page is not an integer, deliver first page.
    all_ads_paginated = paginator.page(1)
except EmptyPage:
    # If page is out of range (e.g. 9999), deliver last page of results.
    all_ads_paginated = paginator.page(paginator.num_pages)

context = {
    'all_ads': all_ads_paginated,
}
return context

需要得到这个： 帖子1，帖子2，帖子3，横幅1，后4，帖子5，帖子6，横幅2

def all_ads(request):
all_ads = CreateNewAdvert.objects.filter(is_active=True)

paginator = Paginator(sort_adds(all_ads), 10)  # Show 25 contacts per page
page = request.GET.get('page')
try:
    all_ads_paginated = paginator.page(page)
except PageNotAnInteger:
    # If page is not an integer, deliver first page.
    all_ads_paginated = paginator.page(1)
except EmptyPage:
    # If page is out of range (e.g. 9999), deliver last page of results.
    all_ads_paginated = paginator.page(paginator.num_pages)

context = {
    'all_ads': all_ads_paginated,
}
return context

结果

def sort_adds(obj):
sell_adds_list = list()
banner = Banners.objects.all()
counter = 0
adds_counter = 0
for i in obj:
    sell_adds_list.append(i)
    adds_counter += 1
    if adds_counter % 3 == 0:
        if not counter > len(banner):
            sell_adds_list.append(banner[counter])
            counter += 1
        else:
            pass
return sell_adds_list
