扭转一段男多女的关系

它应该是:

toy_stance.boy_set.all()

请看这里:

http://docs.djangoproject.com/en/dev/topics/db/queries/#many-to-many-relationships

from django.db import models

class Toy(models.Model):
    name = models.CharField('Name', max_length=250)

    def __unicode__(self):
        return self.name

class Boy(models.Model):
    name = models.CharField('Name', max_length=250)
    toys_owned = models.ManyToManyField(Toy, blank = True)

    def __unicode__(self):
        return self.name

如果toy=是toy类的实例,那么toy.boy_set.all()就是你要找的
