我正在为Odoo 9开发一个模块，我有一个名为＆＃34; job_id＆＃34;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＆＃34; account_id＆＃34;的字段，它是与res.partner有关系的Many2One。 job_id仅对account_id是唯一的。
我的目标是将job_id计算为并存储以用于将来的增量;在account_id更改或创建表单时。目前，我在create方法中运行我的函数。
在Odoo shell中，我发现如果我做了类似于下面的操作，它可以工作但是当我将它添加到我的模块时，它错误地说该模型没有＆＃34; env＆＃34;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']
在发现显然Odoo对于确切的env可用时很挑剔之后，我将我的功能修改为以下。
而不是
ids = self.env bla bla bla我在做
ids = self.pool.get('custom.custom').search(cr, uid, [('account_id','=',vals['account_id'])], context=context)
除了添加简单地将所有这些变量的值输出到日志的调试行之外，我的函数没有其他任何改变。
当我创建我的第一条记录时，我没有遇到任何问题，我的日志显示了这一点：
2017-01-24 18:49:23,211 7875 DEBUG [redacted database] openerp.addons.custom.models.models: ####### make_job_id, the_ids: [] 2017-01-24 18:49:23,212 7875 DEBUG [redacted database] openerp.addons.custom.models.models: ####### make_job_id, job_ids: 1 2017-01-24 18:49:23,212 7875 DEBUG [redacted database] openerp.addons.custom.models.models: ####### make_job_id, vals[job_id]: 0 2017-01-24 18:49:23,213 7875 DEBUG [redacted database] openerp.addons.custom.models.models: ####### make_job_id, vals[job_id]: 1
但是，在为该帐户创建新记录时，我会收到以下引用：

我所看到的是＆＃34; self.pool.get＆＃34; 不返回ID为＆＃34; self.env＆＃34;确实如此，而只是返回id。
我可以对我的函数做些什么来使用self.pool.get提供的id？
答案 0 :(得分：0)
正如您所提到的，“搜索”方法仅返回ID而不返回对象。尝试在“搜索”之后使用“浏览”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)
