我在django rest freamework应用程序中创建了新模型，并且出现了此错误消息：

TypeError: unsupported operand type(s) for %: 'DeferredAttribute' and 'dict'

这是错误屏幕截图：

我不明白是什么问题？

这是我的models.py：

from django.db import models

class TblUseraccounts(models.Model):
    uid = models.AutoField(primary_key=True)
    username = models.CharField(unique=True,max_length=20)
    alias_username = models.CharField(unique=True,max_length=20,blank=True,null=True)

    class Meta:
        managed = False
        db_table = 'tbl_user_accounts'
        ordering = ['uid']


class TblUserDetails(models.Model):
    detail_id = models.IntegerField(primary_key=True)
    useraccount = models.ForeignKey(TblUseraccounts,models.DO_NOTHING,related_name=TblUseraccounts.uid)
    first_name = models.CharField(max_length=25,null=True)
    last_name = models.CharField(max_length=45,null=True)
    birthdate = models.DateTimeField(blank=True,null=True)
    record_time = models.DateTimeField()
    creator = models.ForeignKey(TblUseraccounts,related_name=TblUseraccounts.uid,db_column='creator')

    class Meta:
        managed = False
        db_table = 'tbl_user_details'
        ordering = ['record_time']


class TblUserPassword(models.Model):
    id_password = models.AutoField(primary_key=True)
    useraccount_id_pwd = models.ForeignKey(TblUseraccounts,db_column='useraccount_id_pwd')
    salt = models.CharField(max_length=200,null=True)
    hash = models.CharField(max_length=200,db_column='creator')

    class Meta:
        managed = False
        db_table = 'tbl_user_password'
        ordering = ['record_time']

您当然应该知道我是Python编程的新手。

我想问题出在TblUserDetails模型中，但是我不知道这是什么吗？

非常感谢您的关注。
