Hi, 

   While i am trying to create record rule using xml i got error please anyone can give any suggestion how to clear this

Code:

<record id="manager_of_dept _can_access_all_leaves" model="ir.rule">
            <field name="name">Manager of dept can access all leaves</field>
            <field name="model_id" ref="model_hr_holidays"/>
            <field name="domain_force">[('employee_id.department_id.manager_id.user_id', '=', user.id)]</field> 
            <field name="perm_read" eval="True"/>
            <field name="perm_write" eval="True"/>
            <field name="perm_unlink" eval="True"/>
            <field name="perm_create" eval="True"/>             
            <field name="global" eval="0" />
            <field name="groups" eval="[(4,[ref('hr_payroll_kenya.hr_department_manager')])]"/>        
</record>

Error:
