在Odoo总账代表上添加自定义字段

Question

我试图在Odoo总账报表中添加一个名为x_gstn的自定义字段，但它显示以下错误

    Odoo Server Error
    Traceback (most recent call last):

Traceback (most recent call last):
  File "/usr/lib/python2.7/dist-packages/odoo/addons/base/ir/ir_qweb/qweb.py", line 315, in _compiled_fn

Template: 579
Path: /templates/t/t/t[4]/div/table/tbody/t/tr[2]/td[4]/span
Node: <span t-esc="line['x_gstn']"/>

所以我不知道怎么纠正它

请与我分享你的想法。。。在
