Question

我已经在以下位置询问与此相关的问题 How can I update first_name, last_name & email of Django model User and update other field in separate models

但是我没有找到合适的解决方案。这就是为什么我使这个问题类似于那个问题。

我有 pages.views.py ：

from django.shortcuts import render, redirect
from .forms import CreateUserForm
from accounts.models import Account
from django.contrib import messages

def signupPage(request):
    if request.user.is_authenticated:
        return redirect('/')
    else:
        form = CreateUserForm()
        if request.method == 'POST':
            form = CreateUserForm(request.POST)
            if form.is_valid():
                user = form.save()

                # focus on this line
                Account.objects.create(user=user)

                messages.success(request, 'Signup success. Now, you can login.')
                return redirect('login')
            else:
                messages.warning(request, 'Signup failed. Please, try again.')
        context = {'form':form}
        return render(request, 'signup.html', context)

此外，我还有 accounts.models.py ：

from django.db import models
from django.contrib.auth.models import User

class Account(models.Model):

    user = models.ForeignKey(User, null=True, on_delete=models.CASCADE)

    # This field is used for to update django model User
    first_name=models.CharField(max_length=30, null=True, blank=False)
    last_name=models.CharField(max_length=30, null=True, blank=False)
    email = models.EmailField(max_length=30, null=True, blank=True)

    profile_photo = models.ImageField(upload_to='profile', null=True)
    mobile_number = models.PositiveBigIntegerField(null=True)
    date_of_birth = models.DateField(auto_now_add=False, auto_now=False, null= True)
    zip_code = models.IntegerField(null=True)
    address = models.CharField(max_length=225, null=True)
    website = models.URLField(max_length=100, null=True)
    bio = models.CharField(max_length=225, null=True)

在 Accounts.view.py 中：

from django.shortcuts import render, redirect
from .forms import AccountForm
from .models import Account
from pages.forms import CreateUserForm
from django.contrib import messages
from django.contrib.auth.models import User

首先，我尝试过：

def profileSettingsPage(request, pid):
    user= User.objects.get(id=pid)
    form = AccountForm(instance=user)
    if request.method == 'POST':
        form = AccountForm(request.POST, request.FILES, instance=user)
        if form.is_valid():

            user.first_name = form.cleaned_data.get('first_name')
            user.last_name = form.cleaned_data.get('last_name')
            user.email = form.cleaned_data.get('email')
            user.save()

            form.save()

            messages.success(request, 'Profile saved.')
        else:
            messages.warning(request, 'Faile to saved profile')
    context = {'form':form}
    return render(request, 'profile-settings.html', context)

但是它将仅保存用户模型，而不保存AccountForm。

然后我替换user = request.user。同样，它仅保存用户模型，而不保存AccountForm。

同样，我替换user = Account.objects.get(id=pid)。然后，我遇到错误 DoesNotExist：帐户匹配查询不存在。

即使我尝试过

def profileSettingsPage(request, pid):
    form = AccountForm()
    if request.method == 'POST':
        form = AccountForm(request.POST, request.FILES)
        if form.is_valid():
            form.save()
            user = User.objects.get(id=pid)
            user.first_name = form.cleaned_data.get('first_name')
            user.last_name = form.cleaned_data.get('last_name')
            user.email = form.cleaned_data.get('email')
            user.save()
            messages.success(request, 'Profile saved.')
        else:
            messages.warning(request, 'Faile to saved profile')
    context = {'form':form}
    return render(request, 'profile-settings.html', context)

它保存了两个模型，但是问题在于它创建了一个新模型，并将空值保存在Account模型的ForeignKey中，其他字段按原样保存，还用这些值保存了User模型。

现在，我的问题是如何更新在pages.views.py和Django User模型中同时创建的Account模型？

我对传递实例值感到困惑。 我和每个人都一样吗？还是我做错了？

class Account(models.Model):

    user = models.OneToOneField(User, null=True, on_delete=models.CASCADE)

    # This field is used for to update django model User
    first_name=models.CharField(max_length=30, null=True, blank=False)
    last_name=models.CharField(max_length=30, null=True, blank=False)
    email = models.EmailField(max_length=30, null=True, blank=True)

    profile_photo = models.ImageField(upload_to='profile', null=True)
    mobile_number = models.PositiveBigIntegerField(null=True)
    date_of_birth = models.DateField(auto_now_add=False, auto_now=False, null= True)
    zip_code = models.IntegerField(null=True)
    address = models.CharField(max_length=225, null=True)
    website = models.URLField(max_length=100, null=True)
    bio = models.CharField(max_length=225, null=True)

def profileSettingsPage(request, pid):
    form = AccountForm()
    if request.method == 'POST':
        user = User.objects.get(id=pid)
        user.first_name = request.POST.get('first_name')
        user.last_name = request.POST.get('last_name')
        user.email = request.POST.get('email')
        user.save()
        instance = Account.objects.get(user=user)
        form = AccountForm(request.POST, request.FILES,instance=instance)
        if form.is_valid():
            form.save()
            messages.success(request, 'Profile saved.')
        else:
            messages.warning(request, 'Faile to saved profile')
    context = {'form':form}
    return render(request, 'profile-settings.html', context)

我无法在Django Views.py中同时更新两个模型
