I have the following model:
class Document(BaseModel):
name = models.CharField(max_length=150,blank=True)
type = models.ForeignKey(DocumentType)
description = models.TextField(blank=True)
file =
models.FileField(upload_to="data/documentation/document/%Y/%m/%d",blank=True)
And suppose, I have the file "/tmp/test.txt" in my local filesystem.
How could I add this file to a new model usign the django shell?
I've tryed by instantiating a new Document, and then doing:
object.file = File(open("/tmp/test.xt"))
object.save()
But this gives me the following error:
Traceback (most recent call last):

Thanks a lot.
