Django queryset calling only objects belonging to User - django

Question

I'm unable to figure out how to only call a queryset of items that belong to a specific User in the django forms.
dropoffs/models.py
class DropoffItem(models.Model):
user = models.ForeignKey(settings.AUTH_USER_MODEL, null=True)
dropoff = models.ForeignKey('Dropoff', null=True, blank=True)
product = models.ForeignKey(Product)
location = models.CharField(max_length=120, choices=LOCATION_CHOICES, default="Customer")
def __str__(self):
return str('%s' + " " + "(" + '%s' + ")") %(self.product.title, self.product.sku)
def sku(self):
return self.product.sku
def title(self):
return self.product.title
def dropoff_id(self):
return str(self.dropoff.id)
forms.py
class AddPickupItemForm(forms.ModelForm):
dropoffitem = forms.ModelChoiceField(queryset=DropoffItem.objects.none())
class Meta:
model = PickupItem
# fields = ["product", "quantity"]
fields = ['dropoffitem']
def __init__(self, user, *args, **kwargs):
# self.request = kwargs.pop("request")
the_user = kwargs.pop('user', None)
super(AddPickupItemForm, self).__init__(*args, **kwargs)
if the_user is not None:
self.fields["dropoffitem"].queryset = DropoffItem.objects.filter(user=the_user)
views.py
def add_item_to_pickup_order(request):
request.session.set_expiry(120000)
try:
user = request.user
the_id = request.session['pickup_id']
pickup = Pickup.objects.get(id=the_id)
except:
user = request.user
new_pickup_order = Pickup(user=user)
new_pickup_order.save()
request.session['pickup_id'] = new_pickup_order.id
the_id = new_pickup_order.id
pickup = Pickup.objects.get(id=the_id)
try:
dropoffitem = DropoffItem.objects.filter(user=user)
except DropoffItem.DoesNotExist:
pass
except:
pass
form = AddPickupItemForm(request.POST, user=request.user)
if request.method == "POST":
dropoffitem_id = int(request.POST['dropoffitem'])
pickup_item = PickupItem.objects.create(pickup=pickup, dropoffitem_id=dropoffitem_id)
pickup_item.save()
return HttpResponseRedirect('%s'%(reverse('add_item_to_pickup_order')))
context = {
"pickup": pickup,
"form": form,
}
return render(request, 'pickups/create_pickup_order.html', context)
With the modifications to init, I'm getting a TypeError of: init() got multiple values for keyword argument 'user'.
Could that be because of how I'm requesting a 'session'?

Answer 1

class AddPickupItemForm(ModelForm):
def __init__(self,*args,**kwargs)
the_user = kwargs.pop('user',None)
super(AddPickupItemForm, self).__init__(*args,**kwargs)
if the_user is not None:
self.fields['dropoffitem'].queryset = DropOffItem.objects.filter(user=the_user)
In other words, pass your user to the form when instantiating, if you need to.
