11850	Intermediate model order not applied to related model	pielgrzym	sebastian.hillig	"Hi,

Here is a slightly modified example from django m2m with intermediate model docs (note the meta class with order in Membership model):


{{{
class Person(models.Model):
    name = models.CharField(max_length=128)

    def __unicode__(self):
        return self.name

class Group(models.Model):
    name = models.CharField(max_length=128)
    members = models.ManyToManyField(Person, through='Membership')

    def __unicode__(self):
        return self.name

class Membership(models.Model):
    person = models.ForeignKey(Person)
    group = models.ForeignKey(Group)
    date_joined = models.DateField()
    invite_reason = models.CharField(max_length=64)
    class Meta:
        ordering = ('date_joined')
}}}


Now if we try to access the group members (as in django docs):

{{{
>>> beatles.members.all()
[<Person: Ringo Starr>, <Person: Paul McCartney>]
}}}

'''They are sorted with order of Person model, not intermediate model. You have to manually assign order_by to achieve the desired effect:'''

{{{
>>> beatles.members.all().order_by('membership__date_joined')
}}}

It would be nice to be able to specify the intermediate order as default order for ManyRelatedManager."	New feature	closed	Database layer (models, ORM)	1.1	Normal	wontfix	model ordering, many to many, through	FunkyBob	Accepted	0	0	0	0	0	0
