Hello devs,

I have a question towards OpenERP experts

We cant' inherit directly method defined for field selection.

Two Solutions

1.a/ Either you do this on main class model

    def _get_type_selection(self, cr, uid, context=None):
        """ To inherit to add type """
        return []

    _columns = {
        'type': fields.selection(
            _get_type_selection,
            'Type',),

1.b/ and defined again field on each inherit class
    def _get_type_selection(self, cr, uid, context=None):
        res = super(MyClass, self)._get_type_selection(cr, uid, context=context)
        res.append(('myvalue', My Value'),)
        return res

     _columns = {
        'type': fields.selection(
            _get_type_selection,
            'Type',),

2.a/ Either you do that in the main model

    def _get_type_selection(self, cr, uid, context=None):
        """ To inherit to add type """
        return []

    def __get_type_selection(self, cr, uid, context=None):
        return self._get_type_selection(cr, uid, context=context)

    _columns = {
        'type': fields.selection(
            __get_type_selection,
            'Type',),

2.b/ only this on each inherit class:

    def _get_type_selection(self, cr, uid, context=None):
        res = super(MyClass, self)._get_type_selection(cr, uid, context=context)
        res.append(('myvalue', My Value'),)
        return res

First solution is used for example here
in http://bazaar.launchpad.net/~stock-logistic-core-editors/carriers-deliveries/7.0/files/9/delivery_carrier_label_postlogistics.

Mainly at Akretion we think second solution is better,

Thanks for your feed back
