I am trying to abstract a log app that I have made for my project to make
it more DRY. In order to achieve this I have tried to implement Generic FKs
class Modification(models.Model):
content_type = models.ForeignKey(ContentType)
object_id = models.PositiveIntegerField()
content_object = generic.GenericForeignKey('content_type', 'object_id')
action = models.PositiveSmallIntegerField(choices=ACTION_TYPE_CHOICES,
db_index=True)
modifier = models.ForeignKey(User)
modified_on = models.DateTimeField(auto_now=True)
This appears to function as intended.
I also have another app that I would like to query the logs for:
class NewApp(models.Model):
prefix = models.CharField(max_length=50,choices=PREFIXES, blank=True)
first_name = models.CharField(max_length=255)
last_name = models.CharField(max_length=255)
modifications = generic.GenericRelation(Modification)
Is it possible please to query and return the relevant results from both
models in one queryset? For example, I want to do something similar to this:
content_type = ContentType.objects.get_for_model(NewApp)
last_modified =
Modification.objects.select_related().distinct('object_id').filter(content_type=content_type).order_by('object_id',
'-modified_on')
The above, doesn't, but I need to achieve the fields from NewApp as well as
Modification.
Thank you for any assistance.
