hello all,
I have a generic relation Flag, with a FlagType:
class FlagType(models.Model):
name = models.CharField(maxlength=50)
description = models.TextField()
class Flag(models.Model):
type = models.ForeignKey(FlagType) # type of flag
content_type = models.ForeignKey(ContentType)
object_id = models.PositiveIntegerField()
content_object = generic.GenericForeignKey()
user = models.ForeignKey(User)
created = models.DateTimeField()
So, for example "illegal" or "to feature" would be flags. Now we're
flagging Song objects and I would like a queryset that gets me all Songs
flagged with a flag of type "illegal".
I can do:
flag = FlagType.objects.get(name='illegal')
ctype = ContentType.objects.get_for_model(Song)
flagged = Flag.objects.filter(type=flag,
content_type=ctype).order_by('-created')
songs = [item.content_object for item in flagged ]
But the problem is: I can't do extra things to this list like order_by()
or an extra filter() or exclude().
How can I get the same result, but still have a queryset (containing
Songs) instead of a list??
