I want inherit the class stock_return_picking(osv.osv_memory):

In this class exist the function view_init (def view_init(self, cr, uid, fields_list, context=None):).

I want overwrite all of this function, is possible?

I'm trying do this:

class stock_return_picking(osv.osv_memory):
    _name = 'stock.return.picking'
    _inherit = "stock.return.picking"
    _description = 'Return Picking'

def view_init(self, cr, uid, fields_list, context=None):
         Creates view dynamically and adding fields at runtime.
         @param self: The object pointer.
         @param cr: A database cursor
         @param uid: ID of the user currently logged in
         @param context: A standard dictionary
         @return: New arch of view with new columns.
        if context is None:
            context = {}
        res = super(stock_return_picking, self).view_init(cr, uid, fields_list, context=context)
        record_id = context and context.get('active_id', False)
        if record_id:
            pick_obj = self.pool.get('stock.picking')
            pick = pick_obj.browse(cr, uid, record_id, context=context)

           My code here

            if pick.state not in ['done','confirmed','assigned']:
                raise osv.except_osv(_('Warning!'), _("You may only return pickings that are Confirmed, Available, Shipped or Delivered!"))
            valid_lines = 0
            return_history = self.get_return_history(cr, uid, record_id, context)
            for m  in pick.move_lines:
                if m.state == 'done' and m.product_qty * m.product_uom.factor > return_history.get(m.id, 0):
                    valid_lines += 1
            if not valid_lines:
                raise osv.except_osv(_('Warning!'), _("No products to return (only lines in Done state and not fully returned yet can be returned)!"))
        return res

But the function doesn't do nothing because is not called.

Anyone helps me?
