I’m using incoterm module from Nan-Tic (https://bitbucket.org/nantic/trytond-incoterm/src). With this module, we could define a default incoterm and incoterm place for a party.
In a custom module, with a model parent-child, i’ve a supplier field in the parent class and i would like to get default values depending of the supplier field on the lines for the fields incoterm and incoterm place. Usually those two fields are updated with a method on_change on the supplier/party. But in my case, supplier become readonly when there is lines, and i would like each new line with default values for both fields.
Thanks for help !
