Question

当我想从寄存器中获取信息时，我对Django有问题。我可以得到他们的名字，姓氏和电子邮件，但没有昵称和毕业学校。我以为我做对了，因为我在Forms.py

中添加了昵称和学校

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):
    first_name = forms.CharField()
    last_name = forms.CharField()
    nickname = forms.CharField()
    school = forms.CharField()
    email = forms.EmailField()


    class Meta:
        model = User
        fields = ['username', 'password1', 'password2',
                 'first_name', 'last_name', 'nickname', 'school']


class UserUpdateForm(forms.ModelForm):
    first_name = forms.CharField()
    last_name = forms.CharField()
    nickname = forms.CharField()
    school = forms.CharField()
    email = forms.EmailField()


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


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

models.py

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


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'

    def save(self, *args, **kwargs):
        super().save(*args, **kwargs)

        img = Image.open(self.image.path)

        if img.height > 300 or img.width > 300:
            output_size = (300,300)
            img.thumbnail(output_size)
            img.save(self.image.path)

views.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'Your account has been created! You are now able to log in')
            return redirect('login')
    else:
        form = UserRegisterForm()
    return render(request, 'users/register.html', {'form': form})


@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, f'Your account has been updated!')
            return redirect('profile')

    else:
        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)

我试图通过在views.py中添加form.cleaned_data.get进行保存，但是仍然无法正常工作。我感谢所有帮助。

问题是您没有将“昵称”和“毕业学校”保存到任何模型（基于models.py）。首先，当您执行以下操作时，您将从用户模型继承：

''' 从django.contrib.auth.models导入用户

类配置文件（models.Model）： user = models.OneToOneField（User，on_delete = models.CASCADE）

'''

这样做只能保存Profile模型和User模型中的内容，我建议阅读https://docs.djangoproject.com/en/2.1/ref/contrib/auth/详细说明User模型所具有的内容（用户名，密码等）。

最后，我将昵称和毕业学校添加到个人资料模型中，它应该可以工作。

Django，无法保存数据表单
