Model is not iterable in Django - django

Question

I'm getting this error when I click on a button.
When I click the button I'm calling a function named apply.
So first of all, I've two models, JobServices and MissionEffectuee, the table MissionEffectuee is normally filled with content of JobServices.
The 2 models:
class JobServices(models.Model):
user = models.ForeignKey(User, on_delete=models.CASCADE, null=True) #create_user
service_name = models.CharField(max_length=100, default="nom du service")
hour = models.IntegerField(default="Heures")
amount = models.FloatField(default="Cout")
service_date = models.DateTimeField(auto_now_add=True, null=True)
description = models.CharField(max_length=2000, null=True, default="annonce")
image_url = models.CharField(max_length=2000, null=True, blank=True)
image = models.ImageField(null=True, blank=True)
class MissionEffectuee(models.Model):
user = models.ForeignKey(User, on_delete=models.CASCADE, null=True, blank=True)
service = models.ForeignKey(JobServices, on_delete=models.CASCADE, null=True)
rcd_date = models.DateTimeField(auto_now_add=True, null=True)
Here is the views methods
def apply(request, my_id):
task_applied = JobServices.objects.get(id=my_id)
task_done, failed = MissionEffectuee.objects.get_or_create(id=my_id)
if failed:
for c in task_applied:
task_done.service = c.service_name
task_done.user = c.user
print("it's saved")
task_done.save()
else:
print("Element is already there")
return redirect('../taches')
context = {'task_done': task_done}
return render(request, 'task_apply.html', context)
What I want is whenever I click on the button, service_name of the model Jobservices and user of the model User to be saved in the table MissionEffectuee in the attributes service and user respectively, but as for now, in the table these two columns are filled with hypen (-). But the rcd_date attributes normally filled as I want.
I think the problem is with the foreignkeys

Answer 1

You're doing a get on your JobServices model which will return 1 instance of that model.
So you need to just use that 1 instance, like this;
task_applied = JobServices.objects.get(id=my_id)
task_done, failed = MissionEffectuee.objects.get_or_create(id=my_id)
if failed:
task_done.service = task_applied  # This must be a `JobServices` instance, not the name
task_done.user = task_applied.user
print("it's saved")
task_done.save()
If you used JobServices.objects.filter() then it'd return a queryset of objects from that table and you could iterate over that like you do with for c in task_applied.
