如何在外键django管理中使用详细名称?

class ParentsProfile(models.Model):
    Fathers_Firstname = models.CharField(verbose_name="Firstname", max_length=500,null=True,blank=True)
    Fathers_Middle_Initial = models.CharField(verbose_name="Middle Initial", max_length=500,null=True,blank=True, help_text="Father")
    Fathers_Lastname = models.CharField(verbose_name="Lastname", max_length=500,null=True,blank=True)
    Educational_AttainmentID_Father = models.ForeignKey(EducationalAttainment,on_delete=models.CASCADE,null=True,blank=True)

我已经试着用 教育成就id父=models.ForeignKey(“教育成就”,教育成就,on_delete=models.CASCADE,null=True,blank=True) 但没用
