假设我有两个模型。
class Applicant(models.Model):
firstName = models.CharField(max_length=50)
applicationStatus = models.CharField(max_length=15, default="Pending")
和
class VolInterview(models.Model):
applicant = models.OneToOneField('Applicant')
reasonForRejection = models.CharField(max_length=1000, default="N/A")
现在我想找到那些没有被任何VolInterivew实例引用的申请人。我该怎么做?
