Hi every body, I have an error :
XmlHttpRequestError INTERNAL SERVER ERROR
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 3.2 Final//EN"> <title>500 Internal Server Error</title> <h1>Internal Server Error</h1> <p>The server encountered an internal error and was unable to complete your request. Either the server is overloaded or there is an error in the application.</p>
I dont know how do I fix it. Can you help me?
This is code .py
class danh_sach_kl(osv.Model):
    _name = 'danh.sach.kl'
    _inherit = 'danh.sach.nv'
    _rec_name = 'ly_do_kl'
    
    def onchange_ma_nv(self, cr, uid, ids, ma_nv, context = None):
         v={}
         if ma_nv:
             ma = self.pool.get('danh.sach.nv').browse(cr, uid , ma_nv, context = context)
             v['ten_nv']= ma.ten_nv
             v['ngay_sinh'] = ma.ngay_sinh
             v['ten_bp'] = ma.ten_bp
             v['ten_cd'] = ma.ten_cd
         return {'value':v}
    
    _columns={
              'ma_nv':fields.many2one('danh.sach.nv', 'Mã NV'),
              
              'lan_kl': fields.char('Lần kỷ luật',size = 10),
              'ly_do_kl':fields.char('Lần kỷ luật',size = 10),
              'hinh_thuc':fields.related('ly_do_kl','hinh_thuc',type = 'char',size = 50, string = 'Hình thức kỷ luât'),
              }
If I used two fields in function onchange: It works . but when I increase the number of fields , I have an error, .Anybody can explain it to help me?
Thanks all
