<field name="amount_python_compute">result = hr_line_echeancier.montant</field>

it's linked with contract: class hr_contract(osv.osv):

_inherit = 'hr.contract'

_columns = {
    'line_ech_ids': fields.one2many('hr.line.echeancier', 'line_id', 'ligne Echéancier'),

Hey myriam

now i understand as you commented above that this is liked to contract as one2many field so now just paste this my below code in amount_python_compute field

 for i in contract.line_ech_ids:

note: please be in mind this object (hr.line.echeancier) should be liked to contract as one2many field then this above code will work fine


Sorry !! but it didn't work for me, it generates an error for this code....

due to some design changes I had to make some changes in the link between tables and here is the problem explained otherwise http://help.openerp.com/question/17740/extraction-attribute-with-amount_python_compute/

I'm working on the payroll module and on my own module, this data file is the one of paryroll , i'm trying to add another category ... because I need a category with a calculation rule that retrieves the value of the amount "montant"of class.

This category belongs to that one of the deduction. I need it to compute the payslip.

<record id="hr_AVANCE" model="hr.salary.rule.category">
        <field name="name">Remboursement de Prêts</field>
        <field name="code">AVANCE</field>
    <field name="parent_id" ref="hr_payroll.DED"/>

<record id="hr_payroll.avance" model="hr.salary.rule">
        <field name="name">Remboursement des Prêts</field>
        <field name="code">AVANCE PRET</field>
        <field name="sequence">100000</field>
        <field name="category_id" ref="hr_AVANCE"/>
        <field name="condition_select">none</field>
        <field name="amount_select">code</field>
        <field name="amount_python_compute">result = hr.line.echeancier.montant</field>
        <field name="appears_on_payslip" eval="False"/>
        <field name="note">la valeur des avances et des prêts.</field>


class hr_line_echeancier(osv.osv):
    _name = "hr.line.echeancier"
    _description = "Echeancier"
 _columns = {
        'line_id': fields.many2one('hr.avance.pret', "ligne d\'échéancier"),
        'date_ech': fields.date('Date d\'échéance',
                                states={'draft': [('readonly', False)], 'confirm': [('readonly', False)]}, select=True),
        'montant': fields.float('Montant'),


Thank you so much ..

hey Myrian , you can use only contratc payslip, time and some object there ,,, you can't use your own object there for that case you will have to register your own object in compute button method

you uninstall or remove the depends of thats module surely it will work.

On 5/20/13, 10:13 AM


In file data.xml all data are defined in a static way or relationships between class. so you can do :

<field name="amount_python_compute">your value amount</field>

to compute my payslip i need to have dynamic values and not static ... so i should do something like in the file data of the basic payroll (employee.marital)or ( contract.wage)..... Thank you
