There are two ways to fix what you have so far. First, if you want to leave
the OneToOneField defined in hostsetting, then you will need to restructure
your unixhost save() to look more like this:
def save(self, force_insert=False, force_update=False):
# check if 1-1 record is needed
need_hostsetting = self.id == None
super(unixhost, self).save(force_insert, force_update)
if need_hostsetting:
# Create a hostsetting object
print "adding hostsetting to new object"
hs = hostsetting(host=self)
hs.save()
That is, you need to save the new unixhost (so that it has a pk id in the
database) before you can create and save the new hostsetting that points to
it.
Alternatively, you can move the OneToOneField into the unixhost model, in
which case you'd wind up with something that looks more like this:
class hostsetting(models.Model):
hostinfo = models.BooleanField(blank=True)
users = models.BooleanField(blank=True)
installed = models.BooleanField(blank=True)
delay = models.BooleanField(blank=True)
def __unicode__(self):
return "Settings for host " + self.unixhost.name
class unixhost(models.Model):
name = models.CharField(max_length=50)
fqdn = models.CharField(max_length=50)
os = models.CharField(max_length=10, blank=True)
level = models.CharField(max_length=10, blank=True)
hostsetting = models.OneToOneField(hostsetting)
def save(self, force_insert=False, force_update=False):
# check if 1-1 record is needed
if self.id == None:
# Create a hostsetting object
print "adding hostsetting to new object"
hs = hostsetting()
hs.save()
self.hostsetting = hs
super(unixhost, self).save(force_insert, force_update)
def __unicode__(self):
return self.name
