update_or_create not updating/creating objects - django

Question

I found out that django 1.7 supports now update_or_create() method in queryset.
But when I try it, it is not working. There is no object created when I try this:
models.py
class Model1(models.Model):
name = models.CharField(max_length=100)
status = models.CharField(max_length=100)
user = models.ForeignKey(User, null=True, blank=True)
class Model2(models.Model)
model = models.ForeignKey(Model1, null=True, blank=True)
field1 = models.CharField(max_length=100)
field2 = models.CharField(max_length=100)
user = models.ForeignKey(User, null=True, blank=True)
views.py
def ModelUpdate(request)
model1 = get_object_or_404(Model1, pk=request.POST['lid'])
model1.status =2
model1.save()
#based on the model1, we want to create or update model2
datadict ={'field1' : 1, 'field2':2,}
model2, created = Model2.objects.update_or_create(model=model1,
defaults=datadict)
if created:
print('model2 obj created') #for checking purpose
else:
print('model2 obj not created')
return render(request,'updated.html', {'update':'updated'})
I can see the message model2 obj created but the object was not saved in the database. What could be the problem?
UPDATE
Turns out it was my mistake. In the Model2, I defined the save method without returning super(Model2, self).save(*args, **kwargs)
That's why it didn't save the objects.

Maybe you verifying in the wrong way, because I created project with your models and everything works fine.
In my case I'm verifying that object was created/updated with objects.get() and printing values:
In [1]: from app1 import models
In [2]: m1 = models.Model1.objects.create(name=1, status=1)
In [3]: m1
Out[3]: <Model1: Model1 object>
In [4]: datadict ={'field1' : 1, 'field2':2,}
In [6]: model2, created = models.Model2.objects.update_or_create(model=m1, defaults=datadict)
In [7]: model2, created
Out[7]: (<Model2: Model2 object>, True)
In [8]: models.Model2.objects.get().field1, models.Model2.objects.get().field2
Out[8]: (u'1', u'2')
In [9]: datadict ={'field1' : 3, 'field2':4}
In [10]: model2, created = models.Model2.objects.update_or_create(model=m1, defaults=datadict)
In [11]: model2, created
Out[11]: (<Model2: Model2 object>, False)
In [12]: models.Model2.objects.get().field1, models.Model2.objects.get().field2
Out[12]: (u'3', u'4')
and
In [13]: models.Model2.objects.get().model.id
Out[13]: 1
In [14]: models.Model1.objects.get().id
Out[14]: 1
