Populate Django Model with for-loop

Question

I have a model Task which I want to populate with a for loop.
In a list I have the tasks that should be passed into the model.

My model has actually more than three tasks (Below I have shown only three). The list will also have varying number of entries. The list can also have only one task.

tasks = ['first task', 'second task', 'third task']



class Task(models.Model):
    ad = models.OneToOneField(Ad, on_delete=models.CASCADE, primary_key=True, blank=True, null=False)
    task1 = models.CharField(max_length=256, blank=True, null=True)
    task2 = models.CharField(max_length=256, blank=True, null=True)
    task3 = models.CharField(max_length=256, blank=True, null=True)

    def __str__(self):
        return f'Tasks for {self.ad}'

My approach looks like this:

task_obj = Task.objects.create(
    ad = ad
)
for idx, t in enumerate(tasks):
    task_obj.f'task{idx+1}' = t

Basically this part f'task{idx+1}' should not be a string, but the actual variable of the model.

Is this even possible? Or does an other way exist I am not aware of?

You can use the setattr built-in function to set dynamic attributes:

for idx, t in enumerate(tasks):
    setattr(task_obj, f'task{idx+1}', t)
