KeyError at /accounts/regist/

Question

我有个错误：

KeyError在/accounts/regist/‘电子邮件’。

在此之前，我的用户注册表格中只有用户名和密码列。我想给它添加电子邮件表单，所以我写了。但我发现了错误。我进口：

django.contrib.auth.forms import UserCreationForm
from django.contrib.auth.forms import AuthenticationForm.

而且我的auth_user表有电子邮件栏，所以我不知道如何修复它。我用test.py写的

from django.test import TestCase

# Create your tests here.
class UserTests(APITestCase):
    def setUp(self):
        """
        setUp for testing
        """
        User.objects.create(username='user1', email='email1', password='user1')
        User.objects.create(username='user2', email='email2',password='user2')
        self.user1 = User.objects.get(username='user1')
        self.user2 = User.objects.get(username='user2')

在serializers.py中

class UserSerializer(serializers.HyperlinkedModelSerializer):
    class Meta:
        model = User
        fields = ('id', 'username','email', 'password')
        write_only_fields = ('password')
        read_only_fields = ('id')

        def create(self, validated_data):
          password = validated_data.get('password')
          validated_data['password'] = make_password(password)
          return User.objects.create(**validated_data)

在forms.py中

from django import forms
from django.contrib.auth.forms import UserCreationForm
from django.contrib.auth.forms import AuthenticationForm

class RegisterForm(UserCreationForm):
    def __init__(self, *args, **kwargs):
        super(RegisterForm, self).__init__(*args, **kwargs)
        self.fields['username'].widget.attrs['class'] = 'form-control'
        self.fields['email'].widget.attrs['class'] = 'form-control'
        self.fields['password1'].widget.attrs['class'] = 'form-control'
        self.fields['password2'].widget.attrs['class'] = 'form-control'

在这些代码中，我指定了电子邮件column.So，我应该做些什么来修复它？

根据部分堆栈跟踪，当试图为电子邮件字段定义小部件时，代码会阻塞。但这个字段是在哪里定义的？在任何地方都没有定义。您的代码应该更改为：

class RegisterForm(UserCreationForm):
    email = forms.EmailField(required = True)
    def __init__(self, *args, **kwargs):
        ....
