Get field value of inherited model Odoo 8

Question

Hello to all I have been developing module under Odoo 8. I have a class "hrEmployee" with "_inherit=hr.employee" , now in my hrEmployee there is a One2many field having relation with another model "hr.employee.visa". I want to get the field values of the "hrEmployee" with onchange function defined on the field of "hr.employee.visa". Like when I change field value of "hrEmployee", I can get the field value entered on the current form (hrEmployee). How am I able to achieve this in Odoo v8? My Python code is shown below:

class hrEmployee(models.Model):

    _inherit = "hr.employee"               
    diwan_no = fields.Char('Diwan No', size=30, help='Diwan Number')   
    zeo_number = fields.Char('ZEO Number',size=30, help='ZEO Number')    
    visas_ids = fields.One2many('hr.employee.visas', 'employee_id', 'Visas')                    

class hr_employee_visas(models.Model):       

    _name='hr.employee.visas'
    employee_id = fields.Many2one("hr.employee.visas", "Employee" )

    @api.onchange('visas_number')    
    @api.depends( 'visas_number')    
    def _visa_num(self):    
        cr=self._cr    
        uid=self._uid    
        ids=self._ids
        for id in ids:
            obj1=self.pool.get('hr.employee').browse(cr,uid,id,context=None)  
            print obj1.name_related          

    visas_sponsor = fields.Char('Sponsor')    
    visas_states = fields.Selection([('apply','Apply'),('active','Active'),('expire','Expire'),('cancel','Cancelled')], string='State' )    
    visas_number = fields.Char('Visa No', help='Visa Number')

I tried to use self.pool.get browse but it gives me "False" . Plz guide me or point me my mistake. Hopes for suggestion

It's not clear what you want to achieve. The onchange is client-side action, triggered when edit the visas_number field in the form for hr.employee.visas. What do you expect to be done when that happens? — Daniel Reis
Look the main form is the hrEmployee (that inherits 'hr.employee' ). There is inherited field 'name_related' .A One2many field is used here which is related with the 'hr.employee.visas'. Now the onchange function defined on the child form (model='hr.employee.visas') should print me the value that i entered on the parent form (model='hrEmployee') — Arsalan Sherwani
There is no name_related in your code. You want the employee name to be displayed on the visa form? It should be by default. Sorry, I'm still confused. — Daniel Reis

Try following,

class hr_employee_visas(models.Model):       

    _name='hr.employee.visas'
    employee_id = fields.Many2one("hr.employee", "Employee" )

    @api.onchange('visas_number')    
    @api.depends( 'visas_number')    
    def _visa_num(self):    
        for obj in self:
            print obj.employee_id.name

Here is the mistake

employee_id = fields.Many2one("hr.employee.visas", "Employee" )

You need to set hr.employee here.

No need to write both of the decorators together, in case of any changes into the visas_number field this method will be called, you can use any of the single decorator for this.
