如何在域筛选器odoo中获取7个以上的字段

class MyModel(models.Model):
    _name = 'my.model'
    _description = 'My Model'

    field1 = fields.Char(string='Field 1')
    field2 = fields.Integer(string='Field 2')
    field3 = fields.Float(string='Field 3')
    # 定义更多的字段...

<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="field1"/>
                    <field name="field2"/>
                    <field name="field3"/>
                    <!-- 显示更多的字段... -->
                </group>
            </sheet>
        </form>
    </field>
</record>

my_records = self.env['my.model'].search([('field1', '=', 'value1'), ('field2', '>', 10), ('field3', '<', 5.0)])

my_records_data = my_records.read(['field1', 'field2', 'field3', 'field4', 'field5', 'field6', 'field7', 'field8'])
