獲取http請求之外的odoo 10環境

Question

需要在我的模塊post_load之後獲得'bus.bus'模型。但是，我得到一個異常：

Traceback (most recent call last): 
    File "/path/to/file.py", line 19, in __call__ 
    self.event_bus.sendone('channel', 'message') 
    File "/opt/odoo10/addons/bus/models/bus.py", line 70, in sendone 
    self.sendmany([[channel, message]]) 
    File "/opt/odoo10/addons/bus/models/bus.py", line 54, in sendmany 
    self.sudo().create(values) 
    File "/opt/odoo10/odoo/models.py", line 4870, in sudo 
    return self.with_env(self.env(user=user)) 
    File "/opt/odoo10/odoo/api.py", line 781, in __call__ 
    return Environment(cr, uid, context) 
    File "/opt/odoo10/odoo/api.py", line 726, in __new__ 
    env, envs = None, cls.envs 
    File "/opt/odoo10/odoo/tools/func.py", line 111, in __get__ 
    return self.fget.__get__(None, owner)() 
    File "/opt/odoo10/odoo/api.py", line 699, in envs 
    return cls._local.environments 
    File "/opt/odoo10/venv/local/lib/python2.7/site-packages/werkzeug/local.py", line 72, in __getattr__ 
    raise AttributeError(name) 
AttributeError: environments 

我嘗試讓環境是這樣的：

registry = RegistryManager.get(db_name) 
cursor = registry.cursor() 
return Environment(cursor, None, context={}) 

所以，我怎麼能得到正確的環境http請求外？

嘗試使用以下內容獲取Environment。

from odoo import api, fields, models, _ 

env = api.Environment(cr, SUPERUSER_ID, {}) 
return env
