Hi,
I have a model mapping tables in a database with several foreign keys.
class Scheduler(models.Model):
id_schedule = models.AutoField(primary_key=True)
id_parent = models.ForeignKey
("Scheduler",db_column='id_parent',to_field='id_schedule')
id_object_type = models.ForeignKey(ObjectTypes,
db_column='id_object_type',to_field='id_object_type')
id_action = models.ForeignKey(Actions,
db_column='id_action',to_field='id_action')
id_status = models.ForeignKey(Status,
db_column='id_status',to_field='id_status')
id_release = models.ForeignKey(Releases,
db_column='id_release',to_field='id_release')
id_object = models.IntegerField()
begin_execute = models.DateTimeField(null=True,blank=True)
end_execute = models.DateTimeField(null=True,blank=True)
pid = models.IntegerField()
I am working with an instance of this model and at some point I need
to reload it's attributes from the database.
I couldn't find a correct way to do it. Can somebody help me ?
PS: I tryed to write a "reload" method like this:
def __reload__(self):
self.__init__(**Scheduler.objects.filter
(id_schedule=self.id_schedule).values()[0])
but unfortunately, it updates only the keys but not the objects
associated with the foreign keys !
