How can I get distinct content_types from a model like this?...
In sqlite I did the following and it worked...
sqlite> select distinct content_type_id from booking_managedasset;
class ManagedAsset(models.Model):
content_type = models.ForeignKey(ContentType)
object_id = models.PositiveIntegerField()
content_object = generic.GenericForeignKey('content_type',
'object_id')
name = models.CharField(max_length=100, unique=True,
help_text='Asset Name')
slug = models.SlugField(max_length=100, unique=True,
help_text='Slug')
This works in Django but it is getting all objects from the database
and then using Python to make them distinct.
set([ma.content_type for ma in ManagedAsset.objects.all()])
Is there a way to accomplish this using Django queries?
