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})
