我正在尝试在添加到我的项目的新应用程序中创建一个新表。makemigrations 工作得很好，但 migrate 不工作。这是我的模型
博客/模型.py
from django.db import models
# Create your models here.
from fostania_web_app.models import UserModel
class Tag(models.Model):
tag_name = models.CharField(max_length=250)
def __str__(self):
return self.tag_name
class BlogPost(models.Model):
post_title = models.CharField(max_length=250)
post_message = models.CharField(max_length=2000)
post_author = models.ForeignKey(UserModel, on_delete=models.PROTECT)
post_image = models.ImageField(upload_to='documents/%Y/%m/%d', null=False, blank=False)
post_tag = models.ForeignKey(Tag, on_delete=models.PROTECT)
post_created_at = models.DateTimeField(auto_now=True)
当我尝试执行 python manage.py migrate 时出现此错误
以 10 为底的 int() 的无效文字:'???????? ????????'
UserModel 是在同一项目的另一个应用程序中创建的，这就是为什么我使用语句 from fostania_web_app.models import UserModel
fostania_web_app/models.py
class UserModelManager(BaseUserManager):
def create_user(self, email, password, pseudo):
user = self.model()
user.name = name
user.email = self.normalize_email(email=email)
user.set_password(password)
user.save()
return user
def create_superuser(self, email, password):
'''
Used for: python manage.py createsuperuser
'''
user = self.model()
user.name = 'admin-yeah'
user.email = self.normalize_email(email=email)
user.set_password(password)
user.is_staff = True
user.is_superuser = True
user.save()
return user
class UserModel(AbstractBaseUser, PermissionsMixin):
## Personnal fields.
email = models.EmailField(max_length=254, unique=True)
name = models.CharField(max_length=16)
## [...]
## Django manage fields.
date_joined = models.DateTimeField(auto_now_add=True)
is_active = models.BooleanField(default=True)
is_staff = models.BooleanField(default=False)
USERNAME_FIELD = 'email'
REQUIRED_FIELD = ['email', 'name']
objects = UserModelManager()
def __str__(self):
return self.email
def get_short_name(self):
return self.name[:2].upper()
def get_full_name(self):
return self.name
在我的 setting.py 文件中我有这个:
#custom_user
AUTH_USER_MODEL='fostania_web_app.UserModel'
这是完整的traeback:

ValueError: invalid literal for int() with base 10: '??? ??? ?????'
请您参考如下方法:
错误消息:ValueError:以 10 为底的 int() 的无效文字:'??? ？？？ ????'
根据以 10 为底的 int() 异常:'??? ？？？ ??????' 不符合 int 的条件。 为 '??? 检查 并使用有效的 int 修改该值。blog.0001_initial 迁移？？？ ??????'
您可能在重新运行不是 int() 的 makemigrations 命令时不小心提供了垃圾默认值
