如何更新 Django 模型用户的名字、姓氏和电子邮件并更新单独模型中的其他字段

Question

我已经使用 YT、StackOverflow、Django 文档和其他来源学习 Django 教程几周了。所以，也许我的问题没有意义。我希望你能理解我的问题。如果我的代码有任何错误或者您想给我一些建议，请回复我。

我在我的计算机上本地创建该网站。首先，我使用创建了一个注册页面和登录页面 姜戈模型。

用户登录网站后，在个人资料设置中，我创建了表单字段，如 first_name、last_name、email、mobile_number、date_of_birth、zip_code、address、website、）生物，等。

我有 models.py 用于帐户设置

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

# Create your models here.

class Account(models.Model):
    user = models.ForeignKey(User, null=True, on_delete=models.SET_NULL)
    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 forms.py

from django import forms
from .models import Account

class AccountForm(forms.ModelForm):
    class Meta:
        model = Account
        fields = '__all__'

在模板中

<form class="form mx-auto my-5" method="POST" action="" enctype="multipart/form-data">
    <input name="user" type="hidden" value="{{request.user.id}}" required>
    <div class="form-row">
      <div class="col form-group">
        <label for="first_name" class="font-weight-bold">First name (required):</label>
        <input name="first_name" type="text" id="first_name" class="form-control" placeholder="First name" value="{% if request.user.first_name %}{{request.user.first_name}}{% endif %}" required>
      </div>
      <!-- <div class="col form-group">
        <label for="middle_name">Middle name (optional):</label>
        <input name="middle_name" type="text" id="middle_name" class="form-control" placeholder="Middle name">
      </div> -->
      <div class="col form-group">
        <label for="last_name">Last name (optional):</label>
        <input name="last_name" type="text" id="last_name" class="form-control" placeholder="Last name" value="{% if request.user.last_name %}{{request.user.last_name}}{% endif %}">
      </div>
    </div>
    <div class="form-group">
      <label for="email" class="font-weight-bold">Email address:</label>
      <input name="email" type="email" id="email" class="form-control" value="{{request.user.email}}" placeholder="Your email" required>
    </div>
    <div class="form-row">
      <div class="col form-group">
        <label for="mobile_number" class="font-weight-bold">Mobile number:</label>
        <input name="mobile_number" type="tel" id="mobile_number" class="form-control" placeholder="98********" required>
      </div>
      <div class="col form-group">
        <label for="date_of_birth" class="font-weight-bold">Date of birth:</label>
        <input name="date_of_birth" type="date" id="date_of_birth" class="form-control" required>
      </div>
      <div class="col form-group">
        <label for="zip_code" class="font-weight-bold">Zip code:</label>
        <input class="form-control" id="zip_code" name="zip_code" type="number" min="00000" max="99999" placeholder="55455">
      </div>
    </div>
    <div class="form-row">
      <div class="col form-group">
        <label for="address">Address:</label>
        <input name="address" type="text" id="address" class="form-control" placeholder="Bharatpur-07, Chitwan, Nepal">
      </div>
    </div>
    <div class="form-row">
      <div class="col form-group">
        <label for="website">Website:</label>
        <input name="website" type="url" id="website" class="form-control" placeholder="https://example.com/">
      </div>
    </div>
    <div class="form-row">
      <div class="col form-group">
        <label for="bio">Bio:</label>
        <textarea name="bio" class="form-control" id="bio" rows="5"></textarea>   
      </div>
      <div class="col form-group">
        <br><br>
        <span>Write something about your</span>
      </div>
    </div>
  <button class="btn btn-primary btn-md px-3 my-0 mr-0 float-right" type="submit">Submit</button
</form>

我在views.py中尝试过，它有效。

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

# Create your views here.
def profileSettingsPage(request, pid):
    form = AccountForm()
    if request.method == 'POST':
        form = AccountForm(request.POST, request.FILES)
        if int(request.POST.get('user')) == request.user.id:
            if form.is_valid():
                user = User.objects.get(pk=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()

                 form.save()

                 messages.success(request, 'Profile saved.')
                 return redirect('profile-settings', pid)
        else:
            messages.warning(request, 'Sorry! You enter other username.')
            return redirect('profile-settings', pid)
    context = {'form':form}
    return render(request, 'profile-settings.html', context) 

但是，我想在保存之前对名字、姓氏、电子邮件字段进行验证。我期待一些 is_valid() 能够保存。

另外，我尝试了一些新的东西

现在，在 views.py 中我添加了

from pages.forms import CreateUserForm

这是为注册页面创建的

然后，views.py看起来像这样：

from django.shortcuts import render, redirect
from .forms import AccountForm

from pages.forms import CreateUserForm

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

# Create your views here.
def profileSettingsPage(request, pid):
    form1 = AccountForm()
    form2 = CreateUserForm()
    if request.method == 'POST':
        form1 = AccountForm(request.POST, request.FILES)
        form2 = CreateUserForm(request.POST)
        if int(request.POST.get('user')) == request.user.id:
            if form1.is_valid() and form2.is_valid():
                form2.save()
                form1.save()

                messages.success(request, 'Profile saved.')
                return redirect('profile-settings', pid)
            else:
                messages.warning(request, 'Faile to saved profile')
                return redirect('profile-settings', pid)
        else:
            messages.warning(request, 'Sorry! You enter other username.')
            return redirect('profile-settings', pid)
    context = {'form1':form1, 'form2':form2}
    return render(request, 'profile-settings.html', context)

但是，这对我不起作用。 form1.is_valid() 和 form2.is_valid() 无法传递 True 值并给我消息“无法保存配置文件。”

我的问题是，我想更新Django模型User的first_name，last_name，email字段，其他字段单独更新到下一个模型。

还有一个问题

在上面的models.py中，我使用了ForeignKey()来获取用户（用户名或id）。

在 templates 中，我使用了 {{ request.user.id }} 来获取用户。

是否可以在不接触views.py，forms.py和templates的情况下获取用户（id或用户名）？

编辑： 我在此链接上得到了答案： 我无法在 Django Views.py 中同时更新两个模型

Answer 1

您可以简单地将上下文中的

user_id

传递给模板，然后使用它。

Answer 2

class Account(models.Model):
    user = models.OneToOneField(User, null=True, on_delete=models.SET_NULL)
    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):
    form1 = AccountForm()
    form2 = CreateUserForm()
    if request.method == 'POST':
        instance_user = User.objects.get(pk=request.user.id)
        instance_account = Account.objects.get(user=instance_user)
        form1 = AccountForm(request.POST, request.FILES,instance=instance_account)
        form2 = CreateUserForm(request.POST,instance=instance_user)

        if form1.is_valid() and form2.is_valid():
            form2.save()
            form1.save()
            messages.success(request, 'Profile saved.')
            return redirect('profile-settings')
        else:
            print(form1.errors)
            print(form2.errors)
            messages.warning(request, 'Faile to saved profile')
            return redirect('profile-settings')
    context = {'form1':form1, 'form2':form2}
    return render(request, 'profile-settings.html', context)
