异常值：\'CustomUser\' 对象不可调用 |自定义用户模型

Question

我正在尝试创建自定义用户模型。该模型在命令提示符下运行良好，我也能够登录到管理面板。我也可以访问登录页面。但是当我尝试访问 SignUp 页面时，我看到了以下错误。

        ('o','Organization'),
        ('i','Individual')

    is_superuser = models.BooleanField(default=False) # the person who has highest level of control over database

    # need to specify manager class for this user
    objects = CustomUserManager()

    # we are not placing password field here because the password field will always be required
    REQUIRED_FIELDS = ['user_type', 'account_type']

    USERNAME_FIELD = 'email'

表单.py

from django.contrib.auth.forms import UserCreationForm

class SignUpForm(UserCreationForm):

    class Meta:
        fields = ('user_type','account_type','email', 'password1', 'password2')
        model = CustomUser()

    # def __init__(self, *args, **kwargs) -> None:
    #     super().__init__(*args, **kwargs)

管理员.py

from django.contrib import admin
from accounts.models import CustomUser

# Register your models here.
admin.site.register(CustomUser)

我是 django 开发的新手。请帮帮我。

我期待知道如何解决这种错误

你在文件中的错误：

class SignUpForm(UserCreationForm):

class Meta:
    fields = ('user_type','account_type','email', 'password1', 'password2')
    model = CustomUser()

修复到

model = CustomUser
