编写一个按钮来从表中复制数据Python3、Odoo 14

问题描述

我尝试编写一个复制函数来将数据从表复制到同一个表。

    def formmst_copy_func(self):
        _logger.info('=== formmst_copy_func start ===')
        for record in self:
            formbas_obj = self.env['hre.formmst']
            defaults = {
                'form_no': record.form_no,'hre_orgbas_id': record.hre_orgbas_id.id if record.hre_orgbas_id else False,'form_name': record.hre_formmst_id.form_name,'form_type': record.hre_formmst_id.form_type,'calculate_type': record.hre_formmst_id.calculate_type,'total_score': record.hre_formmst_id.total_score,'hre_formdtl_ids': record.hre_formmst_id.hre_formdtl_ids,}
            formbas_obj.create(defaults)
        _logger.info('=== formmst_copy_func end ===')

hre_formmst_id 是 Many2one 字段。 hre_formdtl_ids 是 One2many 字段。

使用按钮调用此函数。

<record id="form_hre_formbas_copy_wizard" model="ir.ui.view">
    <field name="name">form.hre.formbas.copy.wizard</field>
    <field name="model">hre.formbas.copy.wizard</field>
    <field name="arch" type="xml">
        <form>
            <group col="4">
                <field name="hre_formmst_id"/>
                <newline/>
                <field name="form_no"/>
                <field name="hre_orgbas_id"/>
            </group>
            <footer>
                <button string="copy" name="formmst_copy_func" type="object" class="oe_highlight"/>
                or
                <button string="Cancel" special="cancel" type="object" class="oe_link"/>
            </footer>
        </form>
    </field>
</record>

该函数可以成功复制数据。
但是原始数据中的hre_formdtl_ids消失了。
如何修复该功能？请给我一些建议。谢谢！

解决方法

尝试将 one2many 字段更新为 [(6,ids)] 或 [(4,id)]

用于填充 many2many 和 one2many：

<canvas id="canvas"></canvas>

所以在你的情况下你可以尝试：

(0,{ values })    link to a new record that needs to be created with the given values dictionary
(1,ID,{ values })    update the linked record with id = ID (write *values* on it)
(2,ID)                remove and delete the linked record with id = ID (calls unlink on ID,that will delete the object completely,and the link to it as well)
(3,ID)                cut the link to the linked record with id = ID (delete the relationship between the two objects but does not delete the target object itself)
(4,ID)                link to existing record with id = ID (adds a relationship)
(5)                    unlink all (like using (3,ID) for all linked records)
(6,[IDs])          replace the list of linked IDs (like using (5) then (4,ID) for each ID in the list of IDs)
