ODOO通过BUTTON返回一个ACTION，跳转到一个VIEW

可以参考Odoo采购单的右侧按钮的写法。

简单讲，就是先通过xmlid获取到action_id,继而获取到action，修改action的相关信息，然后将结果返回，即可以实现跳转。

mod_obj = self.pool.get('ir.model.data')
        dummy,action_id = tuple(mod_obj.get_object_reference(cr,uid,'purchase','purchase_rfq'))
        action = self.pool.get('ir.actions.act_window').read(cr,uid,action_id,context=context)
        action['context']={}
        request = self.browse(cr,uid,ids[0],context=context)
        if request.purchase_id:
            action['domain']="[('id','=',"+str(request.purchase_id.id)+")]"
            action['views']=[(False,"form")]
            action['res_id']=request.purchase_id.id
            return action

注意，返回的action是一个Dictionary的结果，而不是action对象，否则将不能跳转。

action['views']=[(False,"form")] views是action的一个属性，值为类似[(view_id,view_mode)]的格式，view_id为False，取默认的view值。
