自动生成的字段“ user_ptr”与同名的声明字段发生冲突 [英] Auto-generated field 'user_ptr' clashes with declared field of the same name
问题描述
我有一个具有CustomUser的Django应用。我的模型类似于
I have a Django app that has CustomUser. My model looks something like
class CustomUser(AbstractBaseUser):
def get_short_name(self):
pass
def get_full_name(self):
pass
firstName = models.CharField(max_length=300)
middleName = models.CharField(max_length=300, blank=True)
lastName = models.CharField(max_length=300, blank=True)
username = models.CharField(unique=True, max_length=50)
businessName = models.CharField(max_length=500, default=None)
mobileNumber = models.CharField(max_length=20)
contactNumber = models.CharField(max_length=20)
addressLine1 = models.CharField(max_length=300)
addressLine2 = models.CharField(max_length=300)
city = models.CharField(max_length=300)
state = models.CharField(max_length=300)
role = models.CharField(max_length=20)
email_id = models.CharField(max_length=300, unique=True)
aadharNumber = models.BigIntegerField(default=0)
panNumber = models.CharField(max_length=20, default=None)
registrationDate = models.BigIntegerField(default=0)
bankDetail = models.ManyToManyField('BankDetail', related_name="bankDetail")
dateCreated = models.DateTimeField(auto_now_add=True)
dateModified = models.DateTimeField(auto_now=True)
objects = AccountManager()
USERNAME_FIELD = 'email_id'
REQUIRED_FIELDS = ['username']
我在遵循以下示例在此博客中 https://afropolymath.svbtle.com/authentication-using-django -rest-framework 来实现用户身份验证。
I was following the example in this blog https://afropolymath.svbtle.com/authentication-using-django-rest-framework to implement User authentication.
运行 makemigrations
时出现以下错误我确实查看了StackOverflow上的一些解决方案,但这些解决方案似乎无法解决我的问题。
I get the following error when I run makemigrations
I did look at a few solutions on StackOverflow but those don't seem to solve my problem.
Django错误消息在定义中添加一个related_name参数
自动生成的_ptr的AlterField迁移中的字段导致FieldError
