Hi all.
I would like to merge one querysets related objects with another querysets related objects. Some sample code to explain:
## Models
# sample models to illustrate problem
class PetShop(models.Model):
id = models.AutoField(primary_key=True)
shop_name = models.CharField(maxlength=255)
cats = models.ManyToManyField(Cat)
class Cat(models.Model):
id = models.AutoField(primary_key=True)
cat_name = models.CharField(maxlength=50, blank=True)
## View
def MergePetsInShop(request):
source_shop = PetShop.objects.get(pk=2)
destination_shop = PetShop.objects.get(pk=3)
#Somehow merge CATS from one shop to the other
result = merge(source_shop.cats,destination_shop.cats)
#save()
How can I do this properly?
Many thanks.
