Re: Unique and null

I suggest that if you set unique, the field must have value, so null=False. Blank=True es for form and template, to set required. Null es for database. Dios L@s Bendiga Saludos, [image: --] daniel.bojorge [image: http://]about.me/daniel.bojorge

Re: Unique and null

I should have said SQL specifies NULL compares Non-equal, the ORM converts None's in python to NULL in SQL for you, as well as all the other things it does On Wed, 2021-04-07 at 15:25 +0100, Roger Gammans wrote: > Hi All, > Let shed some actually light on the whole problem, before people > start pi
