try to set the path value as callable function
def get_path(instance, filename): return "site_media/jobs/%s_%s/%s" % (instance.client, instance.job_number, filename) class Articles(models.Model): .... file_path= models.FilePathField(path=get_path, match=".*\.pdf$", recursive=True)
but I'm not sure if this works, I didn't test it.
