Is it possible get variable value from loop?

For example:

            <t t-set="flag" t-value="False"/>
            <!-- flag now False -->
            <tr t-foreach="o.lines" t-as="line">
                <td><span t-field="line.name"/></td>
                <td><span t-field="line.qty"/></td>
                <t t-set="flag" t-value="True"/>
                <!-- flag now True -->
            </tr>
            <!-- flag again False -->


Variable flag inside loop is different from variable flag outide. How send information outside loop?

A patch and some ideas on how to calculate totals have been added to the github issue. https://github.com/odoo/odoo/issues/4461#issuecomment-72199618

There is a GitHub Issue #4461 on this problem.

UPDATE: A patch to v8 was released and some good programming suggestions were made by Olivier on how to avoid using loops.

Thank you Stephen Mack !

As a workaround we can use:

1) If you can insert output in last iteration then use like:

                <t t-set="total" t-value="0" />
                <t t-foreach="o.order_line" t-as="line">
                    <t t-set="total" t-value="total+line.quantity" />
                    <t t-if="line_last">
                        <t t-esc="total" />
                    </t>
                </t>

​​2) If you can't insert output in loop then use like:

                <t t-set="total" t-value="sum([line.quantity for line in o.order_line])" />

Those are some ugly workarounds. But thanks for posting them.

I agree :(
