Question

我有一个下面定义的注册表格

forms.py

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

class SignUpForm(UserCreationForm):
    display_name = forms.CharField(max_length=30, required=True, help_text='Please provide a display name for your profile')
    class Meta:
        model = User
        fields = ('username', 'password1', 'password2', 'display_name')

在views.py中，我处理了注册过程

views.py

from django.contrib.auth.models import User
from django.contrib.auth import login, authenticate
from .forms import SignUpForm
from django.shortcuts import render, redirect


@csrf_exempt
def signup_users(request):
    if request.method == 'POST':
        form = SignUpForm(request.POST)
        if form.is_valid():
            user = form.save(commit=False)
            username = form.cleaned_data.get('username')
            display_name = form.cleaned_data.get('display_name')
            raw_password = form.cleaned_data.get('password1')

            user.set_password(raw_password)
            user.display_name = display_name
            user.save()
            user = authenticate(username=username, password=raw_password)
            print("signup authencticate", user)
            login(request, user)
            return render(request, 'index.html')
    else:
        form = SignUpForm()
    return render(request, 'signup.html', {'form': form})

用户能够成功注册，但是他们的display_name不会存储在django用户模型中。即使在django管理员中，我也看不到字段display_name。我什至执行了像serializers.serialize("json",User.objects.filter(username=username))这样的查询，但即使在这里它也会显示除display_name之外的所有其他字段。

我在做什么错了？

很简单，django.contrib.auth.models.User模型没有名为display_name的字段，因此当然不会保存它。如果要向用户模型添加字段，则必须provide a custom User model。

表单字段未存储在Django用户模型中
