正在尝试更新django中的用户配置文件

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

class UserProfile(models.Model):
    user = models.OneToOneField(User, on_delete=models.CASCADE)
    bio = models.TextField(blank=True)
    avatar = models.ImageField(upload_to='avatars/', blank=True)

    # 其他配置字段...

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

from django import forms
from .models import UserProfile

class UserProfileForm(forms.ModelForm):
    class Meta:
        model = UserProfile
        fields = ['bio', 'avatar']

    # 可选：你可以添加额外的表单字段或修改字段的属性

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

def update_profile(request):
    profile = request.user.userprofile
    form = UserProfileForm(request.POST or None, request.FILES or None, instance=profile)

    if request.method == 'POST' and form.is_valid():
        form.save()
        return redirect('profile')

    return render(request, 'update_profile.html', {'form': form})

<form method="post" enctype="multipart/form-data">
    {% csrf_token %}
    {{ form.as_p }}
    <button type="submit">更新配置文件</button>
</form>
