Hi all,
I'm probably overlooking something very simple, but still cannot explain
what the code below does wrong:
With these models:
class Vorblendplan(models.Model):
# ...
pass
class Mitarbeiter(models.Model):
# ...
vbp = models.OneToOneField(Vorblendplan, null=True, blank=True,
on_delete=models.SET_NULL)
I try to make sure that a Mitarbeiter object has a proper (not None) vbp
instance. In the manage.py shell:
>>> ma = Mitarbeiter.objects.get(key="F426")
>>> ma.vbp # ok, initially "None"
>>> ma.vbp = Vorblendplan()
>>> ma.vbp.save()
>>> ma.save()
>>> ma = Mitarbeiter.objects.get(key="F426")
>>> ma.vbp # Why still "None"??
This, in contrast, works:
>>> ma = Mitarbeiter.objects.get(key="F426")
>>> ma.vbp # "None"
>>> v = Vorblendplan()
>>> v.save()
>>> ma.vbp = v
>>> ma.save()
>>> ma = Mitarbeiter.objects.get(key="F426")
>>> ma.vbp # ok, as expected
<Vorblendplan: Vorblendplan object>
Why does the first example not work?
Thank you very much, and best regards,
Carsten
