Django:使用自定义表单更新用户字段

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

class UserUpdateForm(forms.ModelForm):
    # 添加自定义字段
    new_field = forms.CharField(max_length=100, required=False)

    class Meta:
        model = User
        fields = ['username', 'email', 'new_field']

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

def update_user(request):
    if request.method == 'POST':
        form = UserUpdateForm(request.POST, instance=request.user)
        if form.is_valid():
            form.save()
            return redirect('profile')  # 重定向到用户个人资料页面
    else:
        form = UserUpdateForm(instance=request.user)
    return render(request, 'update_user.html', {'form': form})

<!-- update_user.html -->
<form method="post">
  {% csrf_token %}
  {{ form.as_p }}
  <button type="submit">保存</button>
</form>
