Update/Change Django中ModelForm中当前User实例的信息

Question

如何通过扩展 一对一关系 个人资料页面来编辑用户（first_name、last_name、电子邮件）的用户实例信息。在我的代码下面没有给我任何错误，但也没有为用户更新数据库中的给定信息。用户模型不是我创建的，但我使用 django.contrib.auth.models.User 我也不想使用 Django 的 UpdateView class。任何帮助将不胜感激。

Django 版本

asgiref==3.3.1
Django==3.1.5

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


class UserUpdateForm(forms.ModelForm):
    first_name = forms.CharField(max_length=30)
    last_name = forms.CharField(max_length=30)
    email = forms.EmailField()

    class Meta:
        model = User
        fields = ['first_name', 'last_name', 'email']


class ProfileUpdateForm(forms.ModelForm):
    class Meta:
        model = Profile
        fields = ['image']

users/views.py

from django.shortcuts import render, redirect
from django.contrib.auth.decorators import login_required
from .forms import UserUpdateForm, ProfileUpdateForm
from django.contrib import messages


@login_required
def profile(request):
    if request.POST == 'POST':
        u_form = UserUpdateForm(request.POST, instance=request.user)
        p_form = ProfileUpdateForm(request.POST, request.FILES, instance=request.user.profile)
        if u_form.is_valid() and p_form.is_valid():
            u_form.save()
            p_form.save()
            messages.success(request, "Your profile has been updated !")
            return redirect('profile')
    else:
        u_form = UserUpdateForm(instance=request.user)
        p_form = ProfileUpdateForm(instance=request.user.profile)

    context = {
        'title': "Profile",
        'act': 'profile',
        'u_form': u_form,
        'p_form': p_form,
    }
    return render(request, 'users/profile.html', context)

{% extends 'base.html' %}
{% load crispy_forms_tags %}
{% block title %} {{ title }} {% endblock title %}

{% block content %}
    <div class="content-section align-content-center">

已解决

错误出现在配置文件视图下方，我正在检查 request.POST == 'POST' 是否应该如下所示。作为 request.POST returns 查询集不是字符串。

@login_required
def profile(request):
    if request.method == 'POST':
        u_form = UserUpdateForm(request.POST, instance=request.user)
        p_form = ProfileUpdateForm(request.POST, request.FILES, instance=request.user.profile)
        if u_form.is_valid() and p_form.is_valid():
            u_form.save()
            p_form.save()
            messages.success(request, "Your profile has been updated !")
            return redirect('profile')
    else:
        u_form = UserUpdateForm(instance=request.user)
        p_form = ProfileUpdateForm(instance=request.user.profile)

    context = {
        'title': "Profile",
        'act': 'profile',
        'u_form': u_form,
        'p_form': p_form,
    }
    return render(request, 'users/profile.html', context)
