我有这个型号：
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")
我想从中创建一个stock.picking，我已经有了这个类的方法：
@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
我从视图中打电话：
<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>
但每次我尝试点击按钮时：

TypeError: super(type, obj): obj must be an instance or subtype of type
有关于此的任何想法吗？
提前致谢。

到目前为止我注意到：create正在等待具有确切值的vals字典。什么是真正的Many2one？ （这就是为什么你需要在开始开发模块之前阅读odoo文档）Many2one只是数据库中存储相关模型ID的列。因为它存储了ID，它存储了Integer值，但在你的情况下，你给它self无法理解的对象create。因此，您必须使用self.id。
注意：在普通模型函数中，您可以使用self为Many2one字段赋值，但是在创建值时，您必须指定精确值，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
最后一次通知：使用PEP8
代码必须易于阅读！

此处不需要super()，因为您要创建另一个odoo模型数据库记录。要执行此操作，请使用注册了所有模型的Environment并调用创建。另外，我不认为self或self.id是vals中字段的正确值。
@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
