Insert error

[asrenzo]

Hi,

Here's my model :

class Image(meta.Model):
    paragraph = meta.ForeignKey(Paragraph)
    creation_date = meta.DateTimeField(null=False, auto_now_add=True)
    update_date = meta.DateTimeField(null=False, auto_now=True)
    name = meta.CharField(maxlength = 255, blank = True)
    img = meta.ImageField(upload_to='imgs')

Here's the traceback

UPDATE maccaferri_images SET
paragraph_id='1',creation_date='',update_date='2005-09-24
07:29:45.401427',legende='yoyo',img='imgs/photo1.jpg',position='0'
WHERE id=1


I guess that the problem occurs when using a conjunction of a :

meta.DateTimeField(null=False, auto_now_add=True)
meta.ImageField(upload_to='imgs') or FileField I suppose.


It looks like during an insert :

1 - The entry is created in the DB
2 - The file is checked and saved on the filesystem
3 - The DB entry is update with the file informations

But the creation_date shouldn't be in the update query or shouldn't be
empty.

Am I right ??
