【问题描述】：

我有一个关于如何在我的 Django 应用中更新个人资料的问题。

问题是当我填写表格中的空格并单击“保存更改”按钮时，内容不会将管理员中的信息更新到个人资料。

你可以在https://github.com/edisonjao5/Django2App看到它。

或者这是配置文件应用程序中的代码：

models.py

from django.contrib.auth.models import User
from django.db import models
from django.db.models.signals import post_save
from django.dispatch import receiver
from sorl.thumbnail import ImageField

class Profile(models.Model):
    user = models.OneToOneField(
        User,
        on_delete=models.CASCADE,
        related_name='profile'
    )
    SOCIAL = (
        ('twitter', 'Twitter'),
        ('facebook', 'Facebook'),
        ('instagram', 'Instagram'),
        ('youtube', 'Youtube'),
        ('github', 'Github'),
    )
    First_Name = models.CharField(max_length=30)
    Last_Name = models.CharField(max_length=30)
    Username = models.CharField(max_length=30)
    image = ImageField(upload_to='profiles')
    Password = models.CharField(max_length=30)
    Social = models.CharField(max_length=30, choices=SOCIAL)

    def __str__(self):
        return self.user.username

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

@receiver(post_save, sender=User)
def update_user_profile(sender, instance, **kwargs):
    instance.profile.save()

views.py

from django.views.generic import DetailView, View, FormView
from django.contrib.auth.mixins import LoginRequiredMixin
from .models import Profile
from .forms import UpdateProfileForm

class UpdateProfileView(LoginRequiredMixin, FormView):
    http_method_names =['get', 'post']
    template_name = 'profiles/update.html'
    form_class = UpdateProfileForm
    success_url = '/'

    def dispatch(self, request, *args, **kwargs):
        self.request = request
        return super().dispatch(request, *args, **kwargs)

    def get_context_data(self, *args, **kwargs):
        context = super().get_context_data(*args, **kwargs)
        context["user"] = self.request.user
        return context

    def form_valid(self, form):
        new_object = Profile.objects.update_or_create(
            FirstName = form.cleaned_data['First_Name'],
            LastName = form.cleaned_data['Last_Name'],
            Username = form.cleaned_data['Username'],
            Image = form.cleaned_data['image'],
            Password = form.cleaned_data['Password'],
        )
        if form.is_valid():
            new_object.save()
        return super().form_valid(form)

forms.py

from django import forms


class UpdateProfileForm(forms.Form):
    FirstName = forms.CharField(max_length=30)
    LastName = forms.CharField(max_length=30)
    Username = forms.CharField(max_length=30)
    Image = forms.ImageField()
    Password = forms.CharField(widget=forms.PasswordInput, min_length=10)

【问题讨论】：

几个cmets。 1. 我强烈建议不要将密码存储为纯文本 2. 如果此视图仅用于更新，请考虑使用 UpdateView 而不是 FormView docs.djangoproject.com/en/3.2/ref/class-based-views/… 该站点将有助于基于类的视图 - ccbv.co.uk/projects/Django/3.2/django.views.generic.edit/…跨度>

【参考方案1】：

在您的 Profile 模型类中，所有字段都是必需的，因为您没有指定 blank=True or null=True。

在这种情况下，def create_user_profile 信号中的 Profile.objects.create(user=instance) 语句会导致问题，因为只有 user 字段已创建，但其他字段留空。

您应该在 Profile 模型类中的字段上使用 'default' 属性或使用 'blank=True, null=True'。

其次，密码永远不应该存储在个人资料中。这不是 Django 的工作方式。它应该在用户对象中。你可以通过Django documentation了解清楚

我的两分钱是这样的：

class Profile(models.Model):
    user = models.OneToOneField(
        User,
        on_delete=models.CASCADE,
        related_name='profile'
    )
    SOCIAL = (
        ('twitter', 'Twitter'),
        ('facebook', 'Facebook'),
        ('instagram', 'Instagram'),
        ('youtube', 'Youtube'),
        ('github', 'Github'),
    )
    First_Name = models.CharField(max_length=30, blank=True, null=True)
    Last_Name = models.CharField(max_length=30, blank=True, null=True)
    Username = models.CharField(max_length=30, blank=True, null=True)
    image = ImageField(upload_to='profiles', default='profiles/default.jpg')
    Social = models.CharField(max_length=30, choices=SOCIAL, blank=True, null=True)
