Question

I am using a file upload in my Django model like this :

 def upload_path(self, filename):
    return 'upload/actualities/%s/%s' % (self.id, filename)

photo = models.ImageField(upload_to=upload_path)

and my adminModel is :

from actualities.models import *
from django.contrib import admin  

class ActualityAdmin(admin.ModelAdmin):
     class Media:
         js = ('/static/js/tiny_mce/tiny_mce.js', '/static/js/textareas.js')

 admin.site.register(Actuality, ActualityAdmin)

Everything works fine except when i edit mu model because it has an id. But when I create it, the file upload happens before the model saving… So i put my file in /media/actualities/None/filename.jpg, and I want /media/2/filename.jpg

How can I force to make the file upload after the model saving?

Thank you!!!

As workaround, try generating UUID for file name (instead of using self.id).
