Aeroo报告行编号

Question

如何在Aeroo报告中进行行号。我找到了这个解决方案，但出现错误

Aeroo Reports: Error while generating the report.
sale.order.line(23,) has no member named "index"
sale.order.line(23,) has no member named "index"
For more reference inspect error logs.: (<type 'exceptions.Exception'>, Exception('Aeroo Reports: Error while generating the report.', UndefinedError('sale.order.line(23,) has no member named "index"',),
for each="line in o.order_line"
<str(o.order_line.index(line)+1)> 

Answer 1

找到了解决方案。mapped将返回列表，然后u可以在列表上进行索引。

str(o.order_line.mapped('id').index(line.id)+1)
