Question

我想在销售订单的sale.order.line.tree视图中显示产品类别，其中包含我编写的以下代码。它显示按组按钮下的类别按钮，但点击它时，我收到以下错误，我不知道如何解决错误：assert groupby_def and groupby_def._classic_write, "Fields in 'groupby' must be regular database-persisted fields (no function or related fields), or function fields with store=True" AssertionError: Fields in 'groupby' must be regular database-persisted fields (no function or related fields), or function fields with store=True

这是我的代码：

from osv import fields, osv<code>
class sales_order_line_category(osv.osv):
_name='sale.order.line'
_inherit='sale.order.line'
_columns={'categ_id': fields.related('product_id', 'categ_id', type='many2one', relation='product.categ_id'),

}

sales_order_line_category（）

我的观点：

`<?xml version="1.0" encoding="utf-8"?>

<record id="view_sale_orderlinecategory" model="ir.ui.view">
        <field name="name">sale.order.line.categoryinherit</field>

        <field name="type">tree</field>

        <field name="arch" type="xml">

            </field>            
        </field>    

    </record>

            </group>


        </field> 
    </record>

        </field>

Answer 1

请您尝试使用以下代码替换？

'categ_id': fields.related('product_id', 'categ_id', type='many2one', relation='product.category', store=True),

检查您的字段categories_id是否必须出现在sale.order.line的树状视图中，您尝试按categories_id进行分组

希望这个帮助
