I have hard coded the code of shop in view in line <field eval="'([7],)'" name="args"/>. I want to get this id from a return value of function. How can i do that?

<record model="ir.cron" id="salesorders_cron">
            <field name="name">sales orders automation</field>
            <field name="interval_number">30</field>
            <field name="interval_type">minutes</field>
            <field name="numbercall">-1</field>
            <field eval="False" name="doall"/>
            <field eval="'sale.shop'" name="model"/>
            <field eval="'automate_orders'" name="function"/>
            <field eval="'([7],)'" name="args"/>
