object has no attribute 'get_notification_display'

I am trying to display human readable label of choicefield. 

def reminder(request, pk=None):
    reminder = get_object_or_404(Reminder, pk=pk)
    print(reminder.id)  # printing correct value
    print(reminder.get_notification_display())
    return render(request, 'reminder.html', {'reminder': reminder, 'title': 'Reminder'})

But it throws this error :

AttributeError: 'Reminder' object has no attribute 'get_notification_display'

Here is the model:

class Reminder(models.Model):
    provider_type = (
        ('Em', 'Email'),
        ('Sm', 'SMS'),
        ('De', 'Desktop'),
        ('Mo', 'Mobile'),
    )
    notification = ArrayField(models.CharField(choices=provider_type, max_length=2, default='Em'))

Here's the documentation on get_FOO_display - what am I missing?

 notification = models.CharField(choices=provider_type, max_length=2, default='Em')

remove the arrayfield as it is not allowing you to create and iterate one

The documentation says

For every field that has choices set, the object will have a get_FOO_display() method

but you don't have any choices set for notification. In other words, you need a NOTIFICATION_CHOICES iterable of lenght two iterables in your class.
