Hi Users,
So I have a DB that has a list of backends and there properties and I
have a table that gets updated with if it is able to access and the
status. It is only updated when it is reported down or, if it was
reported down and is currenly back up.
What i want to do is make a queryset that will get only the latest
status for a list of backends.
#models.py
class Backend(models.Model):
src_host = models.CharField(max_length=255)
ip = models.CharField(max_length=45)
port = models.CharField(max_length=8)
endpoint_name = models.CharField(max_length=255)
service_prop_name = models.CharField(max_length=255)
endpoint_url = models.CharField(max_length=255)
class Status(models.Model):
backend = models.ForeignKey(Backend)
timestamp = models.DateTimeField()
status = models.CharField(max_length=255)
class Meta():
get_latest_by = 'timestamp'
What I would like to do is get the latest status reported for the last
ten minutes. Without having to loop through a list querysets and
performing the .latest() function on it.
Is this possible?
Thanks,
Colin
