Question

我有两个模型（User和Profile）。在Profile模型中，您可以看到我有idx字段用于排序。在我的项目中，我显示了配置文件列表，管理员可以通过拖放对它们进行排序。为什么我使用idx。此字段也是不可见的，管理员不会手动更改其值。

问题：如何按个人资料ID修改用户数据。正如我之前所说，我显示了个人资料列表。现在我有编辑表单，我按个人资料ID显示用户数据。当我尝试在更改后提交表单时出现问题。

models.py：

# -*- coding: utf-8 -*-

from django.db import models
from django.contrib.auth.models import User
from django.dispatch import receiver
from django.db.models.signals import post_save, post_delete

class Profile(models.Model):
    user = models.OneToOneField(User, on_delete=models.CASCADE)
    idx = models.IntegerField(verbose_name='Field for sorting, default=0, blank=True,)

    class Meta:
        ordering = ['idx', 'pk']
        db_table = 'user_profile'


@receiver(post_save, sender=User)
def create_or_update_user_profile(sender, instance, created, **kwargs):
    if created:
        Profile.objects.create(user=instance)
    instance.profile.save()

@receiver(post_delete, sender=Profile)
def delete_user(sender, instance=None, **kwargs):
    try:
        instance.user
    except User.DoesNotExist:
        pass
    else:
        instance.user.delete()

forms.py：

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

class UserForm(forms.ModelForm):
    class Meta:
        model = User
        fields = '__all__'

views.py：

class UserEditView(UpdateView):
    template_name = 'users/edit_user.html'
    form_class = UserForm
    model = User

    def get(self, request, *args, **kwargs):
        data = dict()
        profile = Profile.objects.get(pk=self.kwargs['pk'])
        user_edit_form = UserForm(instance=profile.user)
        context = {
            'profile': profile,
            'user_edit_form': user_edit_form
        }
        data['html_user_edit_form'] = render_to_string(
            'users/edit_user.html', context, request=request
        )
        return JsonResponse(data)

    def form_valid(self, form):
        form.save()
        data = dict()
        data['form_is_valid'] = True
        context = {'users': User.objects.all()}
        data['html_users'] = render_to_string('users/users.html', context)
        return JsonResponse(data)

错误：

最后我发现了自己的错误。从url我获取配置文件的id，然后在模板中我需要发送用户的id。

我只需添加context = {'user': profile.user,}，然后使用模板user.id代替profile.id。

如何在OneToOneField中保存用户数据Django的？
