title: relational fields of the same model [ODOO 10 ]
body: <p>is it possible to use a relational field of the own model i've worked?</p>
  
  <p>For example
  _name = 'x.x'
  x_ids = fields.Many2many('x.x')</p>
  
  <p>I need to show the records I've created of the same model in relation field, any suggestions?</p>
