我在 django 中编码并试图弄清楚如何在我的应用中更新用户的个人资料请帮助我我正在尝试学习如何编码，这对我来说是一个很大的学习障碍这是models.py：

from django.db import models
from django.contrib.auth.models import User
# Create your models here.

class Profile(models.Model):
    user = models.OneToOneField(User, on_delete= models.CASCADE)
    image = models.ImageField(default='default.jpg',upload_to="profile_pics")
    
    def __str__(self):
        return f'{self.user.username} Profile'

这是我的观点.py：

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

def register(request):
    if request.method == 'POST':
        form = UserRegisterForm(request.POST)
        if form.is_valid():
            form.save()
            username = form.cleaned_data.get("username")
            messages.success(request, f'Yor account has been created! You are now able to login')
            return redirect('/login')
    else:
        form = UserRegisterForm()
    return render(request, 'users/register.html',{'form': form})
@login_required
def profile(request):
    u_form = UserUpdateForm(instance = request.user)
    p_form = ProfileUpdateForm(instance= request.user.profile)

    context = {
        'u_form': u_form,
        'p_form': p_form
    }

    return render(request, 'users/profile.html', context)

我在 'u_form':u_form 处遇到错误，

这是我的forms.py：

from django import forms
from django.contrib.auth.models import User
from django.contrib.auth.forms import UserCreationForm
from .models import Profile
class UserRegisterForm(UserCreationForm):
    email = forms.EmailField()
    class Meta:
        model = User
        fields = ['username', 'email','password1','password2']

class UserUpdateForm(forms.ModelForm):
    email = forms.EmailField()

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

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

我在这方面遇到了错误 p_form = ProfileUpdateForm()

【问题讨论】：

标签： django django-forms

【解决方案1】：

在 ProfileUpdateForm 中，您定义了没有 Meta 类的模型类名称

模型名称和字段应该像这样在 Meta 类中定义：

class ProfileUpdateForm(forms.ModelForm):

    class Meta:
        model = Profile
        fields = ['image']

【讨论】：

谢谢它有效，必须包含` exclude = ['fields'] `
