Odoo 10 - Call method from XMLRPC

Question

I have extended model stock.picking with a new method called do_new_transfer_xmlrpc which enables a basic new_transfer from XMLRPC.

class Picking(models.Model):
  _inherit = 'stock.picking'

  @api.multi
  def do_new_transfer_xmlrpc(self):
    print 'DEBUG'
    self.do_transfer()
    return ['OK', '']

I try to call that method using:

api.execute_kw(db, uid, pwd, 'stock.picking', 'do_new_transfer_xmlrpc', [[int(picking_id)], {}])

But I get:

Fault: <Fault 1: 'Traceback (most recent call last):\n  File "/usr/lib/python2.7/dist-packages/odoo/service/wsgi_server.py", line 56, in xmlrpc_return\n    result = odoo.http.dispatch_rpc(service, method, params)\n  File "/usr/lib/python2.7/dist-packages/odoo/http.py", line 118, in dispatch_rpc\n    result = dispatch(method, params)\n  File "/usr/lib/python2.7/dist-packages/odoo/service/model.py", line 38, in dispatch\n    res = fn(db, uid, *params)\n  File "/usr/lib/python2.7/dist-packages/odoo/service/model.py", line 157, in execute_kw\n    return execute(db, uid, obj, method, *args, **kw or {})\n  File "/usr/lib/python2.7/dist-packages/odoo/service/model.py", line 101, in wrapper\n    return f(dbname, *args, **kwargs)\n  File "/usr/lib/python2.7/dist-packages/odoo/service/model.py", line 164, in execute\n    res = execute_cr(cr, uid, obj, method, *args, **kw)\n  File "/usr/lib/python2.7/dist-packages/odoo/service/model.py", line 153, in execute_cr\n    return odoo.api.call_kw(recs, method, args, kw)\n  File "/usr/lib/python2.7/dist-packages/odoo/api.py", line 685, in call_kw\n    method = getattr(type(model), name)\nAttributeError: type object \'stock.picking\' has no attribute \'do_new_transfer_xmlrpc\'\n'>

Is the used call method properly written?

Answer 1

This is the right syntax:

api.execute_kw(db, uid, pwd, 'stock.picking', 'do_new_transfer_xmlrpc', [int(picking_id)])
