从另一方获得多对多的一面

Question

我有以下三个模型通过多对多关系连接起来：

class TeamMember(models.Model):
    member_name = models.CharField(max_length=140)
    title = models.CharField(max_length=140, null=True, blank=True)
    email = models.EmailField()
    report = models.ManyToManyField(Report, through='Owner')
class Report(models.Model):
    report_name = models.CharField(max_length=140)
    report_description = models.TextField(null=True, blank=True)
    last_updated = models.DateTimeField(null=True, blank=True)
    metric = models.ManyToManyField(Metric, through='MetricAssociation')
class Owner(models.Model):
    teammember = models.ForeignKey(TeamMember, on_delete=models.CASCADE) 
    report = models.ForeignKey(Report, on_delete=models.CASCADE)

我想建立一个属于特定报告（由所有者指定）但遇到问题的团队成员的对象列表。目前我有报告的ID。我试过了，但似乎错了：

owners = TeamMember.objects.filter(report__id=id).distinct().values_list('name', flat=True)

Answer 1

TeamMember模型中没有字段name。你有member_name而不是

owners = TeamMember.objects.filter(report_id=id).distinct().values_list('member_name', flat=True)

附带说明一下，您可以使用report_id而不是需要联接操作的report__id。
