Odoo Filter many2one field on load

Question

In my module I have a many2one field to select workers for a particular task. According to the requirement that field should only display the workers in the current user's department. Simply this is the code,

 _columns = {
    'employee_id': fields.many2one('hr.employee', 'Employee'),
}

My problem is how to perform such filteration for a field on load? I tried using functional field in a domain in view xml. but It seems functional field gets its value when saving the particular record.

Also I tried adding domain to the field itself, here get_current_user_department is a function returns the department id

_columns = {
    'employee_id': fields.many2one('hr.employee', 'Employee',domain=[('department_id.id','=',get_current_user_department)]),
}

This generates following error,

TypeError: is not JSON serializable

Any suggestion to make this work? Thanks

Also you can take one field for storing current user department you can set default value of current user department.

default_department_id = fields.Many2one('employee.department', 
                                        string='My User',
                                        default='get_department') 

Now you need to create function for set default department.

After that you need to write in XML:

<field name="default_department_id" invisible="1"/>
<field name="employee_id" 
       domain="
           [('department_id','=',default_department_id)]
       "/>
