I am modifying hr_payslip report in custom module. I want to add a custom method to this report for this I need to update localcontext with custom method for this report. I am trying

 

class payslip_report(report_sxw.rml_parse):

    def __init__(self, cr, uid, name, context):
        super(payslip_report, self).__init__(cr, uid, name, context)
        self.localcontext.update({
            'get_payslip_total':self.get_payslip_total,
        })


    def get_payslip_total(self, obj):
        payslip_line = self.pool.get('hr.payslip.line')
        res = []
        total = 0.0
        for id in range(len(obj)):
            if obj[id].appears_on_payslip is True:
                total = total + obj.total

        return total

 

and calling in qweb template like

<td><span t-esc="get_payslip_total(o.line_ids)"/> </td>

 

but getting error  "QWebException: "'NoneType' object is not callable" while evaluating
'get_payslip_lines(o.line_ids)". Can anyone help me what I am missing here?

I'm also stuck with this. Just trying to reuse the parser for a new qweb report and it doesn't seems to be possible...

i've maybe go a solution for my case... and I think that for your case you will need to override payslip_report instead of report_sxw.rml_parse with something like : class payslip_report(payslip_report): and importing previously the payslip_report with someting like import addons.hr_payroll.report.report_payslip hope this help

Yogesh,

In order to inherit your"payslip_report" class, just inherit your previous class, using python inheritance.....as:

from openerp.addons.[your_mocule_name].[directory_structue/parent_folder] import payslip_report

and then redefine the class,

class payslip_report(payslip_report.payslip_report):

# here you can override or add previous/new functions.......

Don't forget to keep your [your_module_name] dependency in __openerp__.py

Hope it helps you and i am posting this post after so much long time, since i got it now and it may help you or someone else :)

You should be inheriting from the payslip_report class in hr_payroll/report/report_payslip.py.  First, before the class definition you should put: from hr_payroll.report import report_payslip.  Then the class definition should be class payslip_report(report_payslip.payslip_report).  This way, you chain your inheritance (this is python inheritance, not Odoo ORM inheritance) through the class that provides the get_payslip_lines method.

Also don't forget to re-register your report with the new parser.  At the end of the py file, add the following line: report_sxw.report_sxw('report.payslip', 'hr.payslip', 'hr_payroll/report/report_payslip.rml', parser=payslip_report) adjust the information as necessary.

Thanks for your reply. I haven't gave a try yet all seems okay to me except registry of new parser. it is qweb report so no .rml.

Hi friends:

I solved it in the following way:

I wanted to increase a column in trial balance, this column show before account balance to period or date chosen by the user in the wizard of trial balance.


First Inherit template of tria balance:

<template id="report_trialbalance_saldo_anterior" inherit_id="account.report_trialbalance">
            <xpath expr="//table[@class='table table-condensed']" position="replace">
                <table class="table table-condensed">
                    <thead>
                        <tr>
                            <th>Code</th>
                            <th>Account</th>
                            <th>Saldo Anterior</th>
                            <th class="text-right">Debit</th>
                            <th class="text-right">Credit</th>
                            <th class="text-right">Balance</th>
                        </tr>
                    </thead>
                    <tbody>
                        <tr t-foreach="lines_comprobacion(data['form'])" t-as="childrenaccount">
                            <t t-if="childrenaccount['type'] == 'view'">
                                <t t-set="style" t-value="'font-weight:bold;'"/>
                            </t>
                            <t t-if="childrenaccount['type'] != 'view'">
                                <t t-set="style" t-value="'font-weight:normal;'"/>
                            </t>
                            <td>
                                <span t-att-style="style" t-esc="childrenaccount['code']"/>                                   
                            </td>
                            <td>
                                <span style="color: white;" t-esc="'.' * (childrenaccount['level'] - 1)"/>
                                <span t-att-style="style" t-esc="childrenaccount['name']"/>
                            </td>
                            <td class="text-right">
                                 <span t-att-style="style" t-esc="childrenaccount['sal_ant']" />
                            </td>
                            <td class="text-right">
                                 <span t-att-style="style" t-esc="childrenaccount['debit']"/>
                            </td>
                            <td class="text-right">
                                <span t-att-style="style" t-esc="childrenaccount['credit']"/>
                            </td>
                            <td class="text-right">
                                <span t-att-style="style" t-esc="formatLang(childrenaccount['balance'], currency_obj=res_company.currency_id)"/>
                            </td>
                        </tr>
                    </tbody>
                </table>          
            </xpath>

        </template>

And the .py in my module is:


import time

from openerp.osv import osv from openerp.report import report_sxw from openerp.addons.account.report.common_report_header import common_report_header from openerp.addons.account.report.account_balance import account_balance from datetime import datetime, timedelta

class account_balance_comprobacion(report_sxw.rml_parse, common_report_header):

    def __init__(self, cr, uid, name, context=None):
        super(account_balance_comprobacion, self).__init__(cr, uid, name, context=context)
        self.sum_debit = 0.00
        self.sum_credit = 0.00
        self.date_lst = []
        self.date_lst_string = ''
        self.result_acc = []
        self.localcontext.update({
            'time': time,
            'lines_comprobacion': self.lines_comprobacion,
            'sum_debit': self._sum_debit,
            'sum_credit': self._sum_credit,
            'get_fiscalyear':self._get_fiscalyear,
            'get_filter': self._get_filter,
            'get_start_period': self.get_start_period,
            'get_end_period': self.get_end_period ,
            'get_account': self._get_account,
            'get_journal': self._get_journal,
            'get_start_date':self._get_start_date,
            'get_end_date':self._get_end_date,
            'get_target_move': self._get_target_move,
        })
        self.context = context


    def lines_comprobacion(self, form, ids=None, done=None):

        #NEW METHOD THAT INCREASES FUNCTIONALITY


class report_trialbalance_comprobacion(osv.AbstractModel):  
    _name = 'report.account.report_trialbalance'
    _inherit = 'report.abstract_report'
    _template = 'account.report_trialbalance'
    _wrapped_report_class = account_balance_comprobacion


That was all i hope it helps

Regards.
