测试平台开发：Django开发实战之注册界面实现(下)

1、评论和用户建立关联

1）修改model:

软关联还是硬关联
默认值是什么
关联方被删除怎么办
如何根据评论找到用户
如何根据用户找到评论

然后执行命令：

pdm run M

pdm run init

这样在表里面就会多一个user_id的字段

2）修改视图，接下来编辑views.py文件

@login_required
def submit(request):

    if request.method == 'GET':
        html = open("submit.html", encoding="utf-8").read()
        return HttpResponse(html)
    elif request.method == 'POST':
        # 获取提交的表单数据
        data = json.loads(request.body)
        # my_sql()
        print(data)
        Feedback.objects.create(user=request.user,
                                quality=data['quality'],
                                attitude=data['attitude'],
                                speed=data['speed'],
                                text=data['text'],
                                anonymous=data['anonymous']
        )
        return JsonResponse({'status': 'success',
                             "data": data})

如果曾经发表过，则不能再发表

@login_required
def submit(request):

    if request.method == 'GET':
        html = open("submit.html", encoding="utf-8").read()
        return HttpResponse(html)
    elif request.method == 'POST':
        # 获取提交的表单数据
        data = json.loads(request.body)
        obj_list = Feedback.objects.filter(user=request.user)
        if obj_list:
            return JsonResponse({'status': 'failed',
                             "message": "你曾经发表过，不能再发表了"})
        print(data)
        Feedback.objects.create(user=request.user,
                                quality=data['quality'],
                                attitude=data['attitude'],
                                speed=data['speed'],
                                text=data['text'],
                                anonymous=data['anonymous']
        )
        return JsonResponse({'status': 'success',
                             "data": data})
