Re: Problem with computed default values

Hi Daniel,

AFAIK, default is called once. I had the same problem. Maybe you can try to prepopulate your new column, with an init function, but you'll have problem with new items if there are created massively. (by import, etc....)

Maybe overload the create function is the best / easier way to do what you want. (I guess your field is readonly and so overload write function is unncessary.)

Kind regards.

Hello all,

I'm in need of some expert help.

I added a field to a model, to be used as a random unique identifier:
     token = fields.Char('Token', default=lambda s: str(uuid.uuid4()))

The problem is that, the already existing records all got the same exact uuid.
It seems that the lambda is evaluated once, before a mass update,  
instead of per record, as I expected.

Am I missing something?
Thanks for any help.
