Hi Mark

You could do it by defining it in an xml like this:

<?xml version="1.0" encoding="utf-8"?>
<odoo>
    <data>
        <template id="easymile_timesheet_assets_backend" name="easymile_timesheet assets" inherit_id="web..assets_backend">
            <xpath expr="." position="inside">
                <script type="text/javascript" src="/easymile_timesheet/static/src/js/hour_report.js"></script>
            </xpath>
        </template>
    </data>
</odoo>

I have same problem, js in my module works until i disable the developer mode (with assets).

I've tried different ways to include js in my template:

<xpath expr="." position="inside">

and 

<xpath expr="//script[last()]" position="after">

but both methods works only in developer mode with assets.

also odoo 10.

As bad workaround i've added my  script directly in web.assets_backend in .../dist-packages/odoo/addons/web/views/webclient_templates.xml file.

Please reply, if you solve this problem.

Hi Axel,

I did that, otherwise my code won't be able to work in debug mode.

My question is how to keep it working after all the compressed in one file in production.

Thanks for taking time to answer me.
