odoo 为单据创建自动编号ir_sequence_data

创建 data/ir_sequence_data.xml 并在__manifest__.py文件中引用

<?xml version="1.0" encoding="utf-8"?>
<odoo>
    <data noupdate="1">
        <record id="seq_sps_order" model="ir.sequence">
            <field name="name">Sps Order</field>
            <field name="code">sps.order.sequence</field>
            <field name="prefix">%(year)s%(month)s%(day)s%(h24)s%(min)s%(sec)s</field>
        </record>
    </data>
</odoo>

重写create方法

    @api.model
    def create(self, vals):
        vals['name'] = self.env['ir.sequence'].next_by_code('sps.order.sequence') or '/'
        print(vals['name'])
        res = super(SpsOrder, self).create(vals)
        return res
