Report_view:


<td class="text-left">
<span t-esc="get_partner_product(doc.partner_id.id,l.product_id.id)"/>
</td>

当我在打印的时候，报出的问题：

QWebException:"'NoneType'objectisnotcallable"whileevaluating'get_partner_product(doc.partner_id.id,l.product_id.id)'

Answer:

在"_name"时，路径的错误，必须要添加上"report"的引用：

classreport_stockpickingout(osv.AbstractModel):_name='report.report_stock.report_stockpickingout'
