openerp Message_post error..NameError：没有定义全局名称'_'

Question

我在表单中创建了一个带有chatter的自定义模块。

我想发布自定义消息。但我得到以下错误。

File "/opt/openerp/my_modules/forum/forum.py", line 22, in function_which_post_msg 
    self.message_post(cr, uid, ids, body=_("New Question has been <b>created</b>"), context=context) 
NameError: global name '_' is not defined 

我.py文件是

import datetime 
import time 
import openerp 
from openerp.osv import osv, fields 


class Course(osv.osv): 
    _name = "forum.course" 
    _inherit = ['mail.thread', 'ir.needaction_mixin'] 

    _columns = { 
       'name' : fields.char(string="Question Title", size=256, required=True), 
       'description' : fields.text(string="Question Description", required=True), 

       } 


    def function_which_post_msg(self, cr, uid, ids, context=None): 
     self.message_post(cr, uid, ids, body=_("New Question has been <b>created</b>"), context=context) 

    def create(self, cr, uid, ids, context=None): 
     self.function_which_post_msg(cr, uid, ids, context=context)

试试这个从OpenERP的导入工具从openerp.tools.translate进口在你的.py文件

导入
