How to pass parameter to Django model?

Question

Django

Good day.
Available model

class Image(models.Model)
  name = models.ImageField(upload_to='относительный каталог для файлов/', blank=True, verbose_name='подпись')

I would like to scatter the images in different directories (mandatory). How to pass this very relative path to the directory to this model? Naming a directory by time is not an option. To generate from a name of a file too not a variant. It should be exactly the string that I will pass when saving the model.

https://docs.djangoproject.com/en/2.0/ref/models/f...

def content_file_name(instance, filename):
    return '/'.join(['content', instance.user.username, filename])

class Content(models.Model):
    name = models.CharField(max_length=200)
    user = models.ForeignKey(User)
    file = models.FileField(upload_to=content_file_name)
