django -用户配置文件在另一个模型中用作外键。如何在表单中显示已登录的用户？

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

class UserProfile(models.Model):
    user = models.OneToOneField(User, on_delete=models.CASCADE)
    # 其他用户配置字段

from django import forms
from django.contrib.auth.decorators import login_required
from django.shortcuts import render

@login_required
def profile(request):
    user = request.user
    profile = user.userprofile

    # 创建一个表单，将用户配置字段作为表单字段
    class ProfileForm(forms.ModelForm):
        class Meta:
            model = UserProfile
            fields = ['field1', 'field2']  # 根据实际字段进行调整

    if request.method == 'POST':
        form = ProfileForm(request.POST, instance=profile)
        if form.is_valid():
            form.save()
    else:
        form = ProfileForm(instance=profile)

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

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