此方法会将( ! ) Parse error: syntax error, unexpected '[' in C:\wamp\www\mayamixx\wp-content\object-cache.php on line 499 Call Stack # Time Memory Function Location 1 0.0018 364080 {main}( ) ..\index.php:0 2 0.0030 367704 require( 'C:\wamp\www\mayamixx\wp-blog-header.php' ) ..\index.php:17 3 0.0045 393160 require_once( 'C:\wamp\www\mayamixx\wp-load.php' ) ..\wp-blog-header.php:13 4 0.0066 410760 require_once( 'C:\wamp\www\mayamixx\wp-config.php' ) ..\wp-load.php:37 5 0.0127 584208 require_once( 'C:\wamp\www\mayamixx\wp-settings.php' ) ..\wp-config.php:96 6 0.1062 4509576 wp_start_object_cache( )表单写在name上，从state更改为draft：

confirm

但每当我试图保存它时，它就会抛出这个：

production_type = fields.Selection([
    ('budgeted','Budgeted'),
    ('nonbudgeted','Non Budgeted'),
    ('direct','Direct Order'),
], string='Type of Order', index=True, copy=False,
help=" ")
state = fields.Selection([
        ('draft','Draft'),
        ('confirm','Confirmed'),
        ('inprogress','In progress'),
        ('print_order_inprogress','Print In Progress'),
        ('finished','Finished'),
        ('cancel','Cancel'),
    ], string='State', index=True, copy=False,
    help=" ")

@api.one
def prod_start_func(self):
    name = '/'
    if self.production_type == 'budgeted':
            name = self.env['ir.sequence'].next_by_code('bsi.production.budgeted') or '/'
    elif self.production_type == 'nonbudgeted':
            name = self.env['ir.sequence'].next_by_code('bsi.production.non_budgeted') or '/'
    elif self.production_type == 'direct':
            name = self.env['ir.sequence'].next_by_code('bsi.production.direct') or '/'

    self.write({
            'state': 'confirm',
            'name' : lambda self, cr, uid, context: self.pool.get('ir.sequence').next_by_code(cr, uid, 'bsi.production.order') or '',
            })

我认为这与此行Traceback (most recent call last): File "C:\Program Files (x86)\Odoo 8.0-20170914\server\.\openerp\http.py", line 546, in _handle_exception File "C:\Program Files (x86)\Odoo 8.0-20170914\server\.\openerp\http.py", line 583, in dispatch File "C:\Program Files (x86)\Odoo 8.0-20170914\server\.\openerp\http.py", line 319, in _call_function File "C:\Program Files (x86)\Odoo 8.0-20170914\server\.\openerp\service\model.py", line 118, in wrapper File "C:\Program Files (x86)\Odoo 8.0-20170914\server\.\openerp\http.py", line 316, in checked_call File "C:\Program Files (x86)\Odoo 8.0-20170914\server\.\openerp\http.py", line 812, in __call__ File "C:\Program Files (x86)\Odoo 8.0-20170914\server\.\openerp\http.py", line 412, in response_wrap File "C:\Program Files (x86)\Odoo 8.0-20170914\server\openerp\addons\web\controllers\main.py", line 944, in call_kw File "C:\Program Files (x86)\Odoo 8.0-20170914\server\openerp\addons\web\controllers\main.py", line 936, in _call_kw File "C:\Program Files (x86)\Odoo 8.0-20170914\server\.\openerp\api.py", line 268, in wrapper File "C:\Program Files (x86)\Odoo 8.0-20170914\server\.\openerp\api.py", line 373, in old_api File "C:\Program Files (x86)\Odoo 8.0-20170914\server\.\openerp\api.py", line 291, in <lambda> File "C:\Program Files (x86)\Odoo 8.0-20170914\server\.\openerp\models.py", line 4057, in <lambda> AttributeError: 'NoneType' object has no attribute 'id'有关，但如果我将其更改为'name' : lambda self, cr, uid, context: self.pool.get('ir.sequence').next_by_code(cr, uid, 'bsi.production.order') or '',，我会得到相同的结果。

有什么想法吗？

Answer 1

您正在尝试在新的api中使用旧的api格式

试试这个： 'name'：lambda self：self.env ['ir.sequence']。next_by_code（'bsi.production.order'）或'/'

还要确保self包含单个记录（正如您使用的是@ api.one）

如果它包含多个记录，请使用@ api.multi

没有记录集可用@ api.model

Answer 2

我想我知道它的问题因为我的上一个答案，你从create方法中删除了return语句，这是错误的你应该保留它我认为你知道这一点。

      @model
      create(self, vals):
              ....
               ....
               return super(bsi_production_order, self).create(vals)

因为当create is donoo期望方法返回一个对象时，在你的情况下你删除了return语句，所以默认情况下调用将返回None。当odoo尝试访问返回记录的id（记录=无）时，他会引发此错误。

请记住，当您覆盖create或write时，此规则始终会调用super，因为创建的实际工作是在models.py中。并且odoo期望write方法返回True。

另一个例子，例如你需要在creting方法之后做逻辑

      @model
       create(self, vals):
          ....
          ....
          record = super(bsi_production_order, self).create(vals)
          ......
          ......
           # always return the object that is created
           return record

在write方法中，只需在这样的情况下返回True

AttributeError：＆＃39; NoneType＆＃39;对象没有属性＆＃39; id＆＃39; - Odoo v8
