Only field of a model can be evaluated by PYSON. There is the PYSON.Id but it will require that you create the category in XML. > If not, how to avoid code redundancy for > default_ method and get_ method for the function field ? You can call the default_ method from the getter method. But you need to have both because the getter will be called only once the record is saved/created. > Is there a better way to implement this "filter" ? i'm looking for examples > in code but unsuccessfully. I think the creation of categories from XML could be a good option. -- Cédric Krier - B2CK SPRL Email/Jabber: cedric.kr...@b2ck.com Tel: +32 472 54 46 59 Website: http://www.b2ck.com/ -- You received this message because you are subscribed to the Google Groups "tryton-dev" group.
