我有两个 Django 模型:Match 和 MatchRegister。我想获取不在 MatchRegister 对象中的所有匹配项的列表,但我无法这样做。你能帮我实现它吗?在我的两个班级之下class Match(models.Model): """Model representing Match object""" match_number = models.CharField( max_length=10 ) home_team = models.ForeignKey( Team, on_delete=models.SET_NULL, null=True, related_name='home_team' ) away_team = models.ForeignKey( Team, on_delete=models.SET_NULL, null=True, related_name='away_team' ) match_category = models.ForeignKey( MatchCategory, on_delete=models.SET_NULL, null=True ) date_time = models.DateTimeField( default=timezone.now ) notes = models.TextField( max_length=1000, blank=True ) last_update = models.DateTimeField( auto_now=timezone.now )class MatchRegister(models.Model): match = models.ForeignKey( Match, on_delete=models.SET_NULL, null=True )
