Re: how to set a unique default value for new fieldsby
Hi Stefan and Ondrej,
I am trying with "post_init_hook" on Odoo 8 without success,
I follow this example : https://github.com/OCA/partner-contact/blob/8.0/partner_external_maps/__openerp__.py
Is "post_init_hook" executed only at installation or -i ? or is available for module update -u ?
Ondrej, is _set_default_value_on_column another way to do ? not easy to find example...

Just beware that this will not work if you are trying to enforce the field's uniqueness as well, for that (on 8.0 and later), you need to hook into _set_default_value_on_column or your constraint is not going to be added. -- Consultant credativ Ltd Suite 5, Bloxam Court Corporation Street UK office: +44 1788 298150 Rugby Email: firstname.lastname@example.org CV21 2DU Web: http://www.credativ.co.uk We would love to hear you your feedback on the service provided.
