问当我们在Django中创建一个竞争表作为其他表的一列的外键时，哪一列将成为外键？

EN

class Webpage(models.Model):
   topic = models.ForeignKey(Topic)
   name = models.CharField(max_length=264,unique=True)
   url = models.URLField(unique=True)

   def __str__(self):
       return self.name

class AccessRecord(models.Model):
   name = models.ForeignKey(Webpage)
   date = models.DateField()

   def __str__(self):
       return str(self.date)
