我有这个方法:
class WizNroctrl(models.TransientModel):
_name = 'wiz.nroctrl'
_description = "Wizard that changes the invoice control number"
name = fields.Char(string='Control Number', size=32, required=True) #32, non keyword error was after string
sure = fields.Boolean(string='Are you sure?')
@api.multi
def set_noctrl(self): #, cr, uid, ids, context=None
""" Change control number of the invoice
"""
#if context is None:
#context = {}
data = self.env['wiz.nroctrl'].read()[0] # cr, uid, ids
if not data['sure']:
raise UserError(
_("Error!"),
_("Please confirm that you want to do this by checking the"
" option"))
inv_obj = self.env['account.invoice']
n_ctrl = data['name']
inv_obj.write(self._context.get('active_id'), {'nro_ctrl': n_ctrl}) #cr, uid, context=context
return {}
我不知道这是否需要 self._ensure_one()
声明,但每次我点击它时,它都会抛出这个:

这是我正在进行的本地化迁移,从 v8 到 v10 社区。
原始代码如下所示:
class WizNroctrl(osv.osv_memory):
_name = 'wiz.nroctrl'
_description = "Wizard that changes the invoice control number"
def set_noctrl(self, cr, uid, ids, context=None):

return {}
_columns = {

'sure': fields.boolean('Are you sure?'),
}
WizNroctrl()
我的疑虑主要来自这一行 data = self.env['wiz.nroctrl'].read()[0]
[0]
参数是否适合新的 API?
关于我提出的另一个问题,有人指出,使用 browse()
应该比 read()
更好?有什么想法吗?

一些注意事项:
- 已添加
self.ensure_one()
从您原来的方法来看,您似乎只对一条记录进行操作。
- 在这种情况下,您不需要
read()
或 browse()
,因为 self
已经是向导记录。
- 假设这将通过向导上的按钮调用,执行
return {'type': 'ir.actions.act_window_close'}
以自动关闭 window 可能更正确。
