Hi Guys,

As per the Odoo documentation given at https://www.odoo.com/documentation/10.0/reference/orm.html#compatibility-between-new-api-and-old-api, it specifies I can make use of the old style method in Odoo 10.0 and the Odoo itself will decorate it appropriately (Automatic Bridging).

But I couldn't quite get it right. I have written a sample class with 2 methods one with Old API style and the Other with new API style, but I was unable to make a call to the old method successfully.

Here is the sample code I was using:

from odoo import models, fields, api

class SampleModule(models.Model):
    _name = 'sample.module'

    column_one = fields.Char("Column One")
    column_two = fields.Char("Column Two")
    column_three = fields.Char("Column Three")

    def old_method(self, cr, uid, ids):
        print self, cr, uid, ids
        return True

    def new_method(self):
        return self.old_method()

Note: I even tried decorating the Old method with @api.cr_uid_ids

When I make a call to the new_method() from a button it is always returning with an error saying old_method requires 4 arguments but only 2 given.

File "/var/www/electrickiwi-nest/www/odoo/addons/web/controllers/main.py", line 889, in call_button
    action = self._call_kw(model, method, args, {})
  File "/var/www/electrickiwi-nest/www/odoo/addons/web/controllers/main.py", line 877, in _call_kw
    return call_kw(request.env[model], method, args, kwargs)
  File "/var/www/electrickiwi-nest/www/odoo/api.py", line 682, in call_kw
    return call_kw_multi(method, model, args, kwargs)
  File "/var/www/electrickiwi-nest/www/odoo/api.py", line 673, in call_kw_multi
    result = method(recs, *args, **kwargs)
TypeError: old_method() takes exactly 4 arguments (2 given)

Can someone please help me with this. Not sure if I am missing anything here.

Thanks in advance.
