django中的未知字段错误

时间：2018-01-30 15:59:11

标签： python django django-models

我正在尝试按照教程操作，当我运行makemigrations时出现此错误，但是在教程中，他们没有得到错误。

这是教程：https://www.codingforentrepreneurs.com/blog/how-to-create-a-custom-django-user-model/

这是我在视频中24:59得到的错误： django.core.exceptions.FieldError：为CustomUser指定的未知字段（用户名）。这是完整的追溯：

django.core.exceptions.FieldError: Unknown field(s) (username) specified for CustomUser

以下是我模特中的相关要点：

from django.db import models
from django.contrib.auth.models import AbstractBaseUser, BaseUserManager


# Create your models here.

class UserManager(BaseUserManager):
    def create_user(self, email, password=None, is_active=True, is_staff=False, is_admin=False):
        if not email:
            raise ValueError("Users must have an email address")
        if not password:
            raise ValueError('Users must have a password')

        user_obj = self.model(
            email=self.normalize_email(email)
        )
        user_obj.set_password(password)  # change user password
        user_obj.staff = is_staff
        user_obj.admin = is_admin
        user_obj.active = is_active
        user_obj.save(using=self._db)
        return user_obj

    def create_staffuser(self, email, password=None):
        user = self.create_user(
            email,
            password=password,
            is_staff=True,
        )
        return user

    def create_superuser(self, email, password=None):
        user = self.create_user(
            email,
            password=password,
            is_staff=True,
            is_admin=True
        )
        return user

class CustomUser(AbstractBaseUser):
    email = models.EmailField(max_length=255, unique=True)
    # full_name = models.CharField(max_length=255, blank=True, null=True)
    is_active = models.BooleanField(default=True)  #can login
    is_staff = models.BooleanField(default=False)  # staff user non superuser
    is_admin = models.BooleanField(default=False)  # superuser
    timestamp = models.DateTimeField(auto_now_add=True)

    # confirm = models.BooleanField(default=False)
    # confirmed_date = models.DateTimeField(default=False)

    USERNAME_FIELD = 'email'

    #USERNAME_FIELD and password are required by default
    REQUIRED_FIELDS = [] #['full_name'] #python manage.py createsuperuser

    objects = UserManager()

    def __str__(self):
        return self.email

    def get_full_name(self):
        return self.email

    def get_short_name(self):
        return self.email

    @property
    def is_staff(self):
        return self.is_staff

    @property
    def is_admin(self):
        return self.is_admin

    @property
    def is_active(self):
        return self.is_active

class Profile(models.Model):
    user = models.OneToOneField(CustomUser)
    #location
    #bio
    #experience
    #profile pic




class GuestEmail(models.Model):
    email = models.EmailField()
    active = models.BooleanField(default=True)
    update = models.DateTimeField(auto_now=True)
    timestamp = models.DateTimeField(auto_now_add=True)

    def __str__(self):
        return self.email

我的forms.py文件：

from django.contrib.auth import get_user_model
#^returns user model that is currently active in this project
from django.contrib.auth.forms import UserCreationForm


class UserCreateForm(UserCreationForm):
    #^make sure that class name is not same name as import
    class Meta:
        fields = ('username', 'email', 'password1', 'password2')
        model = get_user_model()
        #^when users sign up, this is what they will have access to


    def __init__(self,*args,**kwargs):
        super().__init__(*args, **kwargs)
        self.fields['username'].label = 'Display Name'
        #^if project was twitter,
        self.fields['email'].label = "Email Address"

我在settings.py文件中有这个：

AUTH_USER_MODEL = 'accounts.CustomUser'  # changes the built-in user model to ours

感谢任何建议或指示！

1 个答案:

答案 0 :(得分：0)

可能在CustomUser您正在使用的用户名字段中，您在模型中没有{{1}}
