Python open erp 7中的hr_招聘模块出错

我是OpenERP 7的新成员，在继承hr_招聘模块时出错

我覆盖hr\U招聘的搜索方法以筛选出申请 我在hr\U job中添加了job\U code char字段，并且 人力资源申请人中的职位代码申请人

我的代码是：

def search(self, cr, uid, args, offset=0, limit=None, order=None, context=None, count=False):
    ''' Overriden search method'''
    cur_obj=self.pool.get('hr.job')
    cr.execute('SELECT job_code FROM hr_job ')
    list = cr.fetchall()
    ids =  [ i[0] for i in list]
    cr.execute('SELECT id FROM hr_applicant WHERE job_code_applicant IN %s', (tuple(set(ids)),))
    list12 = cr.fetchall()
    ids_applicant =  [ i[0] for i in list12 ]
    return ids_applicant

错误是：

回溯（最近一次呼叫最后一次）：

KeyError:8在您的代码中，为什么不返回搜索方法的super而不是返回direclty id

比如：

人力资源部招聘模块。这里，我假设您正在覆盖hr.applicator对象的搜索方法。但是，通过覆盖搜索，您想做什么呢？你想在哪一个基础上筛选出申请人？请多解释！
