如何在odoo的many2one字段中限制“创建和编辑”权限

from odoo import models, fields, api

class MyModel(models.Model):
    _name = 'my.model'
    
    name = fields.Char(string='Name')
    related_model = fields.Many2one('other.model', string='Related Model')
    user = fields.Many2one('res.users', string='User', default=lambda self: self.env.user)
    can_edit = fields.Boolean(compute='_compute_can_edit', string='Can Edit')
    
    @api.depends('user')
    def _compute_can_edit(self):
        for record in self:
            record.can_edit = record.user == self.env.user or self.env.user.has_group('base.group_system')

<record id="my_model_form_view" model="ir.ui.view">
    <field name="name">my.model.form.view</field>
    <field name="model">my.model</field>
    <field name="arch" type="xml">
        <form>
            <sheet>
                <group>
                    <field name="name"/>
                    <field name="related_model" options="{'no_create_edit': True}"/>
                    <field name="user" readonly="1"/>
                    <field name="can_edit" invisible="1"/>
                </group>
            </sheet>
        </form>
    </field>
</record>
