You can do it using parent.department_id.

<notebook>
<page string="Employees">
    <field name="employee_ids" >
        <tree string="Employees" editable="bottom">
            <field name="nik"/>
            <field name="employee_id" domain="[('department_id', '=',parent.department_id)]" />
            <field name="job_id"/>
        </tree>
    </field>
</page>

This may help you.

First, you need to add a related field to the overtime.overtime_details model to identify the department_id like this:

department_id = fields.Many2one(related="overtime_id.department_id", store=False)

Then, in the xml view now you can filter the employee_id list by the department_id in the tree of the employee_ids field:

<notebook>
<page string="Employees">
    <field name="employee_ids" >
        <tree string="Employees" editable="bottom">
            <field name="department_id" invisible="1"/>
            <field name="nik"/>
            <field name="employee_id" domain="[('department_id', '=', department_id)]" />
            <field name="job_id"/>
        </tree>
    </field>
</page>
</notebook>

回答3:

You can filter the employees in employee_id with domain:

<notebook>
    <page string="Employees">
        <field name="employee_ids" >
            <tree string="Employees" editable="bottom">
                <field name="nik"/>
                <field name="employee_id" domain="[('department_id', '=', department_id)]" />
                <field name="job_id"/>
            </tree>
        </field>
    </page>
</notebook>
