Python Django-不允许具有相同外键类型的属性，如何解决此问题？

在我的Django模型中，这个模型有3个具有相同外键类型的属性

    employee = models.ForeignKey(Employee)
    approved_by = models.ForeignKey(Employee)
    created_by = models.ForeignKey(Employee)

然而，它在执行“makemigrations”后对此表示不满。以下是错误：

SystemCheckError: System check identified some issues:

models.py

class Leave(models.Model):

    leavedate = models.DateField()
    employee = models.ForeignKey(Employee)
    company = models.ForeignKey(Company)
    reason = models.IntegerField(default=0) 
    description = models.CharField(max_length=100)
    status = models.IntegerField(default=0)   

    approval_note = models.CharField(max_length=100)
    approved_by = models.ForeignKey(Employee)
    created_by = models.ForeignKey(Employee)
    created_at = models.DateTimeField(auto_now_add=True)
    updated_at = models.DateTimeField(auto_now=True)


    def __str__(self):
        return self.employee.username

您是否阅读了错误消息中的“提示”？为字段提供

相关的\u name

参数。这样的办法应该行得通

employee = models.ForeignKey(Employee, related_name='leaves')
approved_by = models.ForeignKey(Employee, related_name='approved_leaves')
created_by = models.ForeignKey(Employee, related_name='created_leaves')
