/register/ 处出现 MultiValueDictKeyError 并且有模型错误

Question

“我正在尝试使用 POST 方法检索详细信息，但遇到方法名称错误。我已在下面附加了我的代码，所以请帮我解决它。” 并且也无法在数据库中获取任何信息

Internal Server Error: /register/
Traceback (most recent call last):
  File "J:\good\test\Lib\site-packages\django\utils\datastructures.py", line 84, in __getitem__
    list_ = super().__getitem__(key)
            ^^^^^^^^^^^^^^^^^^^^^^^^
KeyError: 'name'

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "J:\good\test\Lib\site-packages\django\core\handlers\exception.py", line 55, in inner
    response = get_response(request)
               ^^^^^^^^^^^^^^^^^^^^^

    raise MultiValueDictKeyError(key)
django.utils.datastructures.MultiValueDictKeyError: 'name'

模型.py name model也发现错误

from django.db import models
# Create your models here.
class user(models.Model):
    name = models.CharField(max_length=30)
    Email= models.EmailField(max_length=254)
    phone= models.IntegerField()
    account = models.CharField(max_length=10)
    message = models.CharField(max_length=300)

同时注册函数中出现MultiValueDictKeyError。

views.py

from django.shortcuts import render,redirect
from django.contrib.auth.models import User
# Create your views here.
def index(request):
    return render(request,"index.html")
def contact(request):
    return render(request,"contact.html")

def ideagained(request):
    return render(request,"idea_gained.html")

def idea(request):
    return render(request,"idea.html")

def ouridea(request):
    return render(request,"our_idea.html")

def aboutpage(request):
    return render(request,"aboutpage.html")

def register(request):
    name=request.POST['name']
    email=request.POST['email']
    phone=request.POST['phone_number']
    account=request.POST['account']
    message=request.POST['message']
    user=user.objects.create_useryou(name=name, email=email, phone_number=phone, account=account, message=message)
    print("we wil call back you")
    return redirect('/')
 

html 文件

Answer 1

您需要为 html 输入标签提供一个

name

属性。您将使用它的值在视图中访问它。

<input placeholder="Your_name" name="name"... >
<input placeholder="Your Email Address" name="email"... >
<input placeholder="Your Phone Number" name="phone_number"... >
<textarea placeholder="Type your Message Here...." name="message"... ></textarea>
