当我像这样运行迁移时，
PS D:\pythonworkspace\WebLite> python manage.py makemigrations masterit
我收到以下错误消息，
PS D:\pythonworkspace\WebLite> python manage.py makemigrations masterit

这是其他文件，
在 WebApp.Core.DjangoApps.commons 模型中，
class User(models.Model):
user_name = models.CharField(max_length=100, unique=True)
password = models.CharField(max_length=100)
user_id = models.CharField(primary_key=True, max_length=255)
user_department = models.CharField(max_length=100)
email = models.CharField(max_length=70)
WebApp.Core.DjangoApps.Masterit 模型，
class Masterit(models.Model):
item_id_itemcode = models.AutoField(primary_key=True)
item_name = models.CharField(max_length=100)
Bitattribute1 = models.BooleanField()
Bitattribute2 = models.CharField(max_length=100)
Bitattribute3 = models.CharField(max_length=100)
Bitattribute4 = models.CharField(max_length=100)
Bitattribute5 = models.CharField(max_length=100)
created_by = models.ForeignKey(User, on_delete=models.CASCADE, related_name="im_created_by")
created_date = models.DateField(auto_now_add=True)
modified_by = models.ForeignKey(User, on_delete=models.CASCADE, related_name="im_modified_by")
modified_date = models.DateField(auto_now=True)
Settings.py
INSTALLED_APPS = [
'django.contrib.admin',
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.messages',
'django.contrib.staticfiles',
'WebApp.Core.DjangoApps.masterit.apps.masteritConfig',
'WebApp.Core.DjangoApps.commons.apps.CommondataConfig',
]
以下错误是什么
ValueError: Invalid model reference 'WebApp.Core.DjangoApps.commons.User'. String model references must be of the form 'app_label.ModelName'.
app_label.ModelName形式必须是什么？我不明白，我看到了类似的问题must be of the form 'app_label.ModelName'." % model ValueError: Invalid model reference，但这无济于事，因为我的settings.py和AUTH_USER_MODEL中没有正确的位置配置文件。
如何解决此错误？请让我知道是否需要在这个问题上添加更多详细信息？
