Odoo 9，如何使用 self.pool.get 获取记录 ID？
Odoo 9, How can I get a record ID using self.pool.get?
我正在为 Odoo 9 开发一个模块，我有一个名为 "job_id" 的字段。这应该是一个唯一的自动递增整数字段，用于帮助识别我的记录。我有另一个名为 "account_id" 的字段，它是一个与 res.partner 相关的 Many2One。 job_id 仅对 account_id.
是唯一的
我的目标是计算 job_id 并存储 以备将来使用；当 account_id 更改或创建表单时。目前，我是 运行 创建方法中的函数。
在 Odoo shell 中，我发现如果我做了类似于下面的事情，它就起作用了，但是当我将它添加到我的模块时，它出错说模型没有 "env"属性。
def make_job_id(self, cr, uid, vals, context=None):
if context is None:
context = {}
job_ids = []
ids = self.env['custom.custom'].search([('account_id','=',vals['account_id'])]) # Search the custom.custom model for all records who's account_id matches this record's account_id and return object IDs
fields = ids.fields_get('job_id') # Get python field descriptor, always returns id + whatever specified fields
jobs = ids.read(fields) # Read the value of the supplied fields for each record
if len(jobs) > 0:
for i in jobs:
if i.job_id not in job_ids:
job_ids.append(i.job_id)
job_ids = max(job_ids) + 1
else:
job_ids = 1
vals['job_id'] = job_ids
return vals['job_id']
在发现 Odoo 显然对 env 何时可用很挑剔之后，我将函数修改为以下内容。
我正在做
ids = self.pool.get('custom.custom').search(cr, uid, [('account_id','=',vals['account_id'])], context=context) 而不是 ids = self.env bla bla bla
我的函数没有任何其他变化，只是添加了调试行，这些调试行只是将所有这些变量的值输出到日志中。
当我创建第一条记录时，我没有遇到任何问题，我的日志显示如下：

我看到的是 "self.pool.get" 不会 return id 像 "self.env" 的对象会，而只是 return是ID。
我可以对我的函数做些什么才能使用 self.pool.get 提供的 ID？
正如您提到的 "search" 方法 returns 只有 ID 而不是对象。尝试在 "search" 之后使用 "browse" 方法来获取实际对象，如下所示：
objs = self.pool.get('custom.custom').browse(cr, uid, ids, context=context)
