I'm writing a module on Odoo (OpenERP) v.8 to allow timesheet's print. I'm using QWeb report type, but I can't use the fields that I need to use.

If I call a field from res_partner module, it works correctly.

<template id="traceur_contrat">

    <t t-call="report.html_container">

     <t t-foreach="docs" t-as="o">

        <t t-call="report.internal_layout">

            <div class="page">

 <table class="table table-condensed">

                            <tr>

                                <td class="text-center"><strong>Name</strong></td></tr>

 <tr >

                                <td class="text-center"><span t-esc="res_partner.mobile"/></td></tr>

I'm writing a module on Odoo (OpenERP) v.8 to allow timesheet's print. I'm using QWeb report type, but I can't use the fields that I need to use.

If I call a field from res_company module, it works correctly.

<template id="report_timesheet_document">
    <t t-call="report.external_layout">
        <div class="page">
            <div class="row">
                <div>
                    <span t-esc="res_company.name"/>
                </div>
            </div>

If I call a field from other modules, like res_partner, it doesn't work.
