Django 获取用户历史浏览记录(基于Redis缓存)

from django_redis import get_redis_connection


class UserInfoView(LoginRequiredMixin, View):
    '''用户中心-信息页'''
    def get(self, request):
        '''显示'''
        # 获取用户的个人信息
        user = request.user
        address = Address.objects.get_default_address(user)

        # 获取用户的历史浏览记录
        con = get_redis_connection('default')
        history_key = 'history_%d'%user.id

        # 获取用户最新浏览的5个商品的id
        sku_ids = con.lrange(history_key, 0, 4) # [2,3,1]

        # 遍历获取用户浏览的商品信息
        goods_li = []
        for id in sku_ids:
            goods = GoodsSKU.objects.get(id=id)
            goods_li.append(goods)

        # 组织上下文
        context = {'page':'user',
                   'address':address,
                   'goods_li':goods_li}

        return render(request, 'user_center_info.html', context)
