I have written this button which does a simple operation, but Odoo says my arguments are wrong. Its an 'object' type button. Can you help me out?

UPDATE:

Here's my code:

PY:

from openerp.osv import fields, osv

from openerp import api

import openerp.addons.decimal_precision as dp

from openerp.osv import orm

from calendar import monthrange

from datetime import datetime, timedelta

from dateutil import relativedelta



class record(orm.Model):

_name="record"

@api.multi

def button_calculate_monthly_interest(self):

print 'hello Odoo'

def button_monthly_interest(self, cr, uid, ids, context=None):

print("hi")


XML:

<button name="button_calculate_monthly_interest" string="Calculate Monthly Interest" type="object"/>


When I use the old API, I get AttributeError: 'record' object has no attribute 'button_monthly_interest'

When I use new API, I get the error: 1 exact field expected, 5 given.

Hello,


Should be 

def button_calculate_monthly_interest(self, cr, uid, ids, context=None):
   print 'Hello World for current ids (%s)' % ids


or in new API


@api.multi
def button_calculate_monthly_interest(self):
        print 'hello Odoo'

Thank you Mariusz and Jeremy for your answers. But I'm still getting the same type error despite the changes made in the code. expecting 1 parameter but 5 given. What should I do?

Please update your question with full py code (including imports) so we do know what API do you use.

Thats bad - try it like http://pastebin.com/6zmG6Q9k . Try optimizing your imports as well.

I guess you are using new api (your class is models.Model), then you should write before your method @api.multi

Take a look at http://odoo-new-api-guide-line.readthedocs.org/en/latest/ for further reference.
