如何在Odoo12中将多条记录存储到web表单中的One2many字段

class ParentModel(models.Model):
    _name = 'parent.model'
    
    child_ids = fields.One2many('child.model', 'parent_id', string='Children')

class ChildModel(models.Model):
    _name = 'child.model'
    
    name = fields.Char(string='Name')
    parent_id = fields.Many2one('parent.model', string='Parent')

<record id="parent_model_form_view" model="ir.ui.view">
    <field name="name">parent.model.form.view</field>
    <field name="model">parent.model</field>
    <field name="arch" type="xml">
        <form>
            <sheet>
                <group>
                    <field name="child_ids" mode="tree">
                        <tree editable="bottom">
                            <field name="name"/>
                        </tree>
                    </field>
                </group>
            </sheet>
        </form>
    </field>
</record>

<record id="parent_model_view_form" model="ir.actions.act_window.view">
    <field name="name">Parent Model</field>
    <field name="res_model">parent.model</field>
    <field name="view_mode">form</field>
    <field name="view_id" ref="parent_model_form_view"/>
</record>

<record id="parent_model_menu" model="ir.ui.menu">
    <field name="name">Parent Model</field>
    <field name="action" ref="parent_model_view_form"/>
</record>
