python - Django 错误，来自 ('127.0.0.1' 的管道损坏，33609)

Question

我正在创建 Django 项目并遇到此错误。来自 ('127.0.0.1', 33609) 的破损管道。我一直在尝试做的是，我使用 auth_user 表(django 框架的默认用户身份验证表)创建了表，并创建了自己的表。当用户注册时，我将使用 User.objects.create_user() 将其记录在 auth_user 表中，然后我创建自己的对象，然后将 .save() 保存到我的表中。在此步骤中，我创建了嵌套属性，并且我认为我以正确的方式分配了每个属性。据我所知，它们都成功了，记录被保存到数据库中。对于前端，我使用带有函数 .then 的 axios 来接收来自服务器的响应，它给了我错误消息，说 Broken pipe from ('127.0.0.1', 33609)。我尝试了很多方式来调试，并且我尝试过的每一种方式都没有任何意义，因为这两个对象都保存到数据库中。此外，对象映射是正确的(这就是我的想法)。这是我的代码(很长，抱歉)

from django.http.response import JsonResponse
from django.shortcuts import render
from django.contrib.auth import authenticate , login
from django.contrib.auth.models import User
from application1.models import Customer , Status

def register_post(request):
    try:
      # return object {'status_code':  , 'result': "" }
      if request.method == 'GET':
          return JsonResponse({'result': 'invalid request'})
      _name = request.POST.get('name',None)
      _surname = request.POST.get('surname',None)
      _mobile = int(request.POST.get('mobile',None))
      _username = request.POST.get('username',None)
      _password = request.POST.get('password',None)
      _confirm_password = request.POST.get('confirm_password',None)

      if User.objects.filter(username=_username).first() != None:
          return JsonResponse({'status_code': 401 , 'result': 'fail , username already 
                                exist in database'})

      print("This is name >>")
      print(_name)
      print("This is surname >>")
      print(_surname)

      print(_confirm_password)


      if _password != _confirm_password:
          return JsonResponse({'status_code': 408 , 'result': "fail , password doesn't 
                               match with confrim password "})

      # perform create user 
      # insert this record in default django table along with newly created table
      # ----------
      customer_status = Status.objects.get(id = 3)
      print("query customer status object >> ")
      print(customer_status)

      new_user = User.objects.create_user(username = _username , password = _password ,
      first_name = _name , last_name = _surname)
      print("new user created >> ")
      print(new_user)
      new_user.save()
      # insert record along with newly created table

      
      
      # query it from the database and then assign it to the new one
      # just to make sure that it got correct model
      user_query = User.objects.get(username = _username)

      print("before object creation >> ")
      print("This is name >> " + str(_name))
      print("This is surname >> " + str(_surname))
      print("This is mobile >> " )
      print(int(_mobile))
      print("This is customer status query result >> ")
      print(model_to_dict(customer_status))
      print("This is user query object >> ")
      print(model_to_dict(user_query))
      print("------------------- Then object creation --------------------")
    
      new_customer = Customer(name = str(_name) , surname = str(_surname) , mobile = 
                     int(_mobile) , register = user_query ,status = customer_status)
      print("new customer obj created >> ")
      print(model_to_dict(new_customer))
    
      print("before save -----")
      new_customer.save()
      print("everything is done")
    
      return JsonResponse({'status_code': 200 , 'result': 'success'})
  except:
      return JsonResponse({'status_code': 403 , 'result': 'fail to save to database'})

和 urlpatterns 数组

urlpatterns = [
    path('accounts/', include('django.contrib.auth.urls')),
    path('', pages.home , name="home"),
    path('adminpage/' , pages.admin_page , name='admin_page'),
    path('register/' , pages.register , name='register'),
    path('registerpost/' , controllers.register_post , name='register_post'),    
]

# controllers and pages are views in term of django , I use these words for my own understanding

请注意，我使用mysql作为数据库

Answer 1

我也能够解决这个问题。

我的 html 按钮是类型 submit,

我正在发送 ajax(异步)请求，

python 服务器在提交结束前处理了我的 ajax 请求。

因此，这个错误。

解决方案: 不使用 input type="submit"，而是使用 input type="button" 进行 ajax 调用。
