I am extending a module to allow an openerp scheduler to call a method automatically once a day.

The module I extend is account_followup, which allows to send mails in order to remind overdue payments to customers. The action of sending reminder emails in the native module is done by clicking on a button in a wizard.

My extension is creating a cron job that calls the method which is called when the user click on the wizard button.

Here are the technicals details of my cron job:

• object : account_followup.print (there is a table in DB corresponding to this model)
• method : do_process
• arguments : [[1]] (this value is part of my problem we'll see below why)

And below is the the begining of the do_process method :

def do_process(self, cr, uid, ids, context=None):
    if context is None:
        context = {} # this is the case when call from cron job

    #Get partners
    tmp = self._get_partners_followp(cr, uid, ids, context=context)

The local scope variables change depending on the origin the method is called from :

1. Called from the cron job, context is empty, and ids variable is equal to arguments field.

2. Called by the user clicking on the button, context contains usual informations (lang,tz,uid) and ids which is the record just newly created in DB table account_followup_print. This ids is then used by the method _get_partners_followp which fetch the record newly created in table account_followup_print thanks to ids.

My problem is that I don't understand in case 2, how the record is created whilst the method do_process is called directly from the click event (see below the xml view code).

<button name="do_process" string="Send emails and generate letters" type="object" class="oe_highlight"/>

My cron job call the same do_process method but an error is thrown cause no record matches with "static" id from the field arguments :

2014-03-14 11:37:40,654 31224 ERROR openerp_dev openerp.addons.base.ir.ir_cron: Call of self.pool.get('account_followup.print').do_process(cr, uid, *([1],)) failed in Job 15

And finally, I can show as well the call stack that are different between case 1 and case 2 :

1.

addons/base/ir/ir_cron.py", line 136, in _callback
  method(cr, uid, *args)
addons/cap_account_followup/wizard/account_followup_print.py", line 229, in do_process

2.

addons/web/session.py", line 89, in send
  return openerp.netsvc.dispatch_rpc(service_name, method, args)
netsvc.py", line 292, in dispatch_rpc
  result = ExportService.getService(service_name).dispatch(method, params)
service/web_services.py", line 626, in dispatch
  res = fn(db, uid, *params)
osv/osv.py", line 190, in execute_kw
  return self.execute(db, uid, obj, method, *args, **kw or {})
osv/osv.py", line 132, in wrapper
  return f(self, dbname, *args, **kwargs)
osv/osv.py", line 199, in execute
  res = self.execute_cr(cr, uid, obj, method, *args, **kw)
osv/osv.py", line 187, in execute_cr
  return getattr(object, method)(cr, uid, *args, **kw)
addons/cap_account_followup/wizard/account_followup_print.py", line 229, in do_process

I d'ont know if my problem is cleary exposed, let me know if it is blurry.

Thank you for your help

Cheers
