Django如何在内置EditProfileForm上显示用户值

from django.contrib.auth.forms import UserChangeForm
from django.contrib.auth import get_user_model

User = get_user_model()

class CustomEditProfileForm(UserChangeForm):
    class Meta:
        model = User
        fields = ('username', 'email', 'first_name', 'last_name')

from django.shortcuts import render
from .forms import CustomEditProfileForm

def edit_profile(request):
    if request.method == 'POST':
        form = CustomEditProfileForm(request.POST, instance=request.user)
        if form.is_valid():
            form.save()
            # 保存成功后的操作
    else:
        form = CustomEditProfileForm(instance=request.user)
    return render(request, 'edit_profile.html', {'form': form})

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