创建库存从继承的模型，操作按钮采摘 - Odoo V9社区

Question

我有这样的模式：

class fleet_vehicles_services(models.Model): 

@api.model 
def create(self, vals): 
    if vals.get('name', 'Nuevo') == 'Nuevo': 
     vals['name'] = self.env['ir.sequence'].next_by_code('fleet.vehicle.log.services') or '/' 
    return super(fleet_vehicles_services, self).create(vals) 

def _static_location(self): 
    return self.env.ref('fleet_stock.location_stock') 

_inherit = "fleet.vehicle.log.services" 

name = fields.Char('Referencia de Orden', required=True, index=True, copy=False, readonly='True', default='Nuevo') 

x_location_src_id = fields.Many2one('stock.location', string=u'Ubicacion Origen de Productos', required=True, 
            readonly=False, 
            help="Location where the system will look for components.") 
x_location_dest_id = fields.Many2one('stock.location', string=u'Ubicacion Destino de Productos', required=True, 
            readonly=False, default=_static_location, 
            help="Location where the system will look for components.") 
product_id = fields.Many2one('product.template', "Producto") 
product_uom_qty = fields.Float(string='Quantity', digits=dp.get_precision('Product Unit of Measure'), required=True, default=1.0) 
stock_picking = fields.Many2one("stock.picking", "Picking", required=True) 
state = fields.Selection(string="Estados", store=True, readonly=True, related="stock_picking.state") 

我想从它创建一个stock.picking，我已经有一个方法，这个类：

@api.multi 
def create_picking(self,vals): 
    vals = {'x_location_src_id': self, 'x_location_dest_id':self, 'product_id':self, 'product_uom_qty':self} 
    res = super(stock_picking, self).create(vals) 
    return res 

这是我从视图拨打：

<record model='ir.ui.view' id='fleet_vehicle_log_services_form_inherit'> 
     <field name='name'>fleet.vehicle.log.services.form</field> 
     <field name='model'>fleet.vehicle.log.services</field> 
     <field name='inherit_id' ref='fleet.fleet_vehicle_log_services_form'/> 
     <field name="priority">90</field> 
     <field name='arch' type='xml'> 
      <xpath expr="//form//sheet//group[1]" position="before"> 
       <div class="oe_title"> 
      <label for="name" class="oe_edit_only" /> 
      <h1> 
       <field name="name" /> 
      </h1> 
      </div> 
      </xpath> 
      <xpath expr="//form/sheet/group" position="after"> 
       <group string="Ubicaciones de Productos" col="2"> 
       </group> 
       <group><field name="stock_picking"/></group> 
       <group string="Datos del picking"> 
        <button name="create_picking" string="Crear Picking" type="object" class="oe_highlight"/> 
         <tree decoration-info="state == 'draft'" decoration-muted="state in ('cancel','done')" decoration-danger="state in ('confirmed','waiting')" string="Products to Consume"> 
          <field name="product_id"/> 
          <field name="product_uom_qty"/> 
          <field name="x_location_src_id"/> 
          <field name="x_location_dest_id"/> 
          <field name="state" invisible="1"/> 
         </tree> 
        </group> 
      </xpath> 
     </field> 
    </record> 

但每次我尝试点击该按钮时：

res = super(stock_picking, self).create(vals) 
TypeError: super(type, obj): obj must be an instance or subtype of type 

对此的任何想法？

在此先感谢。

Answer 1

这里您不需要super()，因为您想要创建另一个odoo模型数据库记录。要做到这一点，请使用Environment，其中所有型号都已注册并致电创建。我也不相信self或self.id是vals中的字段的正确值。

@api.multi 
def create_picking(self): 
    self.ensure_one() 
    vals = { 
     'x_location_src_id': self.x_location_src_id.id, 
     'x_location_dest_id': self.x_location_dest_id.id, 
     'product_id': self.product_id.id, # shouldn't be set on stock.picking, products are handled on it's positions (stock.move) 
     'product_uom_qty': self.product_uom_qty # the same as for product_id 
    } 
    picking = self.env['stock.picking'].create(vals) 
    return picking 

Answer 2

我到目前为止注意到的是：create正在等待vals字典中的确切值。 Many2one是什么？ （这就是为什么你需要在开始开发模块之前阅读odoo文档）Many2one只是存储相关模型ID的数据库中的一列。因为它存储ID它存储整数值，但在你的情况下，你给它的对象self哪些create不能理解。所以你必须使用self.id。

注意：在正常的模型函数中，您可以使用self将值赋给Many2one字段，但是在创建给定值字典时您必须指定确切值，因为odoo不会为您计算它。

@api.multi 
def create_picking(self,vals): 
    vals = { 
     'x_location_src_id': self.id, 
     'x_location_dest_id': self.id, 
     'product_id': self.id, 
     'product_uom_qty': self.id 
    } 
    res = super(stock_picking, self).create(vals) 
    return res 

而且最后通知：使用PEP8

代码必须易于读取！
