Default FileField names for Django files

Question

I have a model:

class Example(models.Model):
    unique_hash = models.CharField(max_length=32,unique=True)
    content = models.FileField(upload_to='source',blank=True,verbose_name="HTML Content File")

I would like to be able to set the content filename to default to a callable, but I don't see any way to have the callable reference unique_hash (or vice versa). Is this possible?

Answer 1

If you mean that callable should generate filename, I'm not aware of that.

You can, however, use custom storage (see docs, subclass django.core.files.storage.FileSystemStorage) that will provide custom algorithm for filename generation.
