looking at mrp_bom_strucuture_report:
<tr t-foreach="get_children(o.bom_line_ids)" t-as="l">
<td style="padding-left: 20px;">
<span style="color: white;" t-esc="'... '*(l['level'])"/>
<span t-esc="l['pname']"/>
</td>
<td>
<span t-esc="l['pqty']"/>
<span t-esc="l['uname']" groups="product.group_uom"/>
</td>
<td>
<span t-esc="l['code']"/>
...
How does this relate to a model? How do I add my fields I have added to mrp.bom.lines?
Cheers,
Rob
