[FIXED] Default image avatar depending on gender

Issue

I would like to create kind of profiles with default avatars.

GENDER_CHOICES = (
    ('M', 'Male'),
    ('F', 'Female'),
)

class Someone(models.Model):
    name = models.CharField(max_length=120)
    gender = models.Charfield(max_length=1, choices=GENDER_CHOICES)
    image = models.ImageField(upload_to='avatars', default=someone_avatar)

I'm trying to write a function which returns path to my folder with jpg.

def someone_avatar(instance):
    gender = instance.gender
    if gender == 'Male':
        avatar = 'avatars/m.jpg'
    else:
        avatar = 'avatars/f.jpg'
    return avatar

Obviously it doesn't work, so could you give me some advise how to solve it? Maybe I should overwrite save method? Thx.

Edited

Ok, I tried with post_save but it does't work as well:

def set_avatar(instance):
    avatar = instance.image
    gender = instance.gender
    if gender == 'Male':
        avatar = 'persons/m.jpg'
    else:
        avatar = 'persons/f.jpg'
    return avatar

def post_save_avatar(sender, instance, *args, **kwargs):
     if not instance.image:
         instance.image = set_avatar(instance)
post_save.connect(post_save_avatar, sender=Person)

Maybe I shouldn't just set avatar to string like path?

Edit 2

It's working for pre_save.

Solution

Seems like you're looking for post_save signal. It gives you created flag. So you can manually set your desired image in your handler if created is True.
