分析

  1. 支付成功之后，订单页面的状态会由“待支付”变成“待评价”，点击“待评价”按钮，可对购买的商品进行评价。
  2. 用户提交评价之后，用户可以详情页看到用户对商品的评价信息，所以评价接口包括提交评价和查看评价，须在payment应用views.py中定义OrderCommentView视图类，其中分别定义对应Post和get方法来实现提交评价和查看评价

实现

payment应用views.py中定义OrderCommentView视图类

class OrderCommentView(LoginRequiredMixin, View):
    """对订单的评价"""

    def get(self, request):
        """查询未评价的商品"""
        order_id = request.GET.get('order_id')

        try:
            OrderInfo.objects.get(order_id=order_id, user=request.user)
        except OrderInfo.DoesNotExist:
            return HttpResponseNotFound('订单不存在')

        try:
            uncomment_goods = OrderGoods.objects.filter(order_id=order_id, is_commented=False)
        except Exception:
            return HttpResponseServerError('订单商品信息出错')
        uncomment_goods_list = []
        for goods in uncomment_goods:
            uncomment_goods_list.append({
                'order_id': goods.order_id,
                'sku_id': goods.sku.id,
                'name': goods.sku.name,
                'price': str(goods.price),
                'default_image_url': settings.STATIC_URL + 'images/goods/' + goods.sku.default_image.url + '.jpg',
                'comment': goods.comment,
                'score': goods.score,
                'is_anonymous': str(goods.is_anonymous)
            })

        context = {'uncomment_goods_list': uncomment_goods_list}
        return render(request, 'goods_judge.html', context)

    def post(self, request):
        json_dict = json.loads(request.body.decode())
        order_id = json_dict.get('order_id')
        sku_id = json_dict.get('sku_id')
        score = json_dict.get('score')
        comment = json_dict.get('comment')
        is_anonymous = json_dict.get('is_anonymous')

        # 校验参数
        if not all([order_id, sku_id, score, comment]):
            return HttpResponseForbidden("缺少必传参数")

        try:
            OrderInfo.objects.filter(order_id=order_id, user=request.user,
                                     status=OrderInfo.ORDER_STATUS_ENUM['UNCOMMENT'])
        except OrderInfo.DoesNotExist:
            return HttpResponseForbidden('参数order_id错误')
        try:
            sku = SKU.objects.get(id=sku_id)
        except SKU.DoesNotExist:
            return HttpResponseForbidden('参数sku_id错误')

        if is_anonymous:
            if not isinstance(is_anonymous, bool):
                return HttpResponseForbidden('参数is_anonymous错误')

        # 保存评价数据

        (OrderGoods.objects.filter(order_id=order_id, sku_id=sku_id, is_commented=False)
         .update(comment=comment,
                 score=score,
                 is_anonymous=is_anonymous,
                 is_commented=True))

        # 累加评论数据
        sku.comments += 1
        sku.save()

        sku.spu.comments += 1
        sku.spu.save()

        if OrderGoods.objects.filter(order_id=order_id, is_commented=False).count() == 0:
            OrderInfo.objects.filter(order_id=order_id).update(status=OrderInfo.ORDER_STATUS_ENUM['FINISHED'])
        return JsonResponse({'code': RETCODE.OK, 'errmsg': '评价成功'})

在payment应用urls.py新增子路由

path(route='orders/comment/', view=OrderCommentView.as_view()),

商品详情页展示评价，之前已经在goods应用下views.py中定义好了评价信息的get查询，此处只要在goods应用下新增对应的子路由即可。

path('comments/<int:sku_id>', views.GoodsCommentView.as_view()),

提交商品评价的模板goods_judge.html
