I want to duplicate all the information of the record, including the o2m field

<notebook>

     <page string="Job" name="job_estimate_id">

        <field name="job_estimate_id" attrs="{'readonly': [('state', '!=','draft')]}">

            <tree editable="bottom">

                <field name="name" invisible="1" force_save="1"/>

                <field name="job_recruitment_id" />

                <field name="no_of_recruitment" string="Quantity" />

            </tree>

        </field>

    </page>

</notebook>

Sorry, my English is not very good!

Thanks!
