                    <div class="row">
                        <H3>Hi hello </H3>
                    </div>
                    </div>
                    </div>
                </t>
            </t>
            </t>
        </template>

    </data>
</openerp>

when I execute the programme for printing the report I get an empty file, give me any advice please

Answer 1

You need to change file and name attribute of report tag. It always represent module_name.report_template_name

<report
    id="action_report_omega"
    model="omega.model"
    string="Report"
    report_type="qweb-pdf"
    file="your_module_name.report_omega"
    name="your_module_name.report_omega"
/>

Afterwards, upgrade your module and try it. It should work fine.
