Hello everyone,

I have added this fields under account.invoice inorder to get an autoincrement number but it doesn't work

Help me please to figure out my error

    _inherit = 'account.invoice'

    def _get_increment(self, cr, uid, ids, fields, arg, context=None):

        if context is None: context = {}

        res = {}

        if type == 'out_invoice':

            ids = self.search(cr,uid,[('id','!=',False),('type','in',('out_invoice','out_refund'))])

            if ids:

                last_id = ids and max(ids)

                print 'last_id',last_id

                for invoice in self.browse(cr, uid, last_id, context):

                    print 'invoice', invoice

                    res[invoice.id] = invoice.name1

                    invoice.name1 += 1

            return res

    _columns={

              'name1':fields.function(_get_increment, type='integer', string='Name1'),

    }
