我怎樣才能解決這個錯誤：預期單candidat（1,2,3,4）

Question

def _get_index_content(self, cr, uid, ids, fields, args, context=None): 
    res = dict.fromkeys(ids, '') 
    Attachment = self.pool.get('ir.attachment') 
    applicant_ids = self.pool.get('hr.applicant').search(cr, uid, [('email_from', '=', self.browse(cr, uid, ids, context=context).email_candidat)], context=context) 
    attachment_ids = Attachment.search(cr, uid, ['|', '&', ('res_model', '=', 'candidat.base'), ('res_id', 'in', ids), '&', ('res_model', '=', 'hr.applicant'), ('res_id', 'in', applicant_ids)], context=context) 
    for attachment in Attachment.browse(cr, uid, attachment_ids, context=context): 
     res[attachment.res_id] += attachment.index_content or '' 
    return res     


def _content_search(self, cr, user, obj, name, args, context=None): 
    record_ids = set() 
    Attachment = self.pool.get('ir.attachment') 
    ids = obj.search(cr, uid, []) 
    applicant_ids = self.pool.get('hr.applicant').search(cr, user, [('email_from', '=', self.browse(cr, user, ids, context=context).email_candidat)], context=context) 
    args = ['&'] + args + ['|', '&', ('res_model', '=', 'candidat.base'), ('res_id', 'in', ids), '&', ('res_model', '=', 'hr.applicant'), ('res_id', 'in', applicant_ids)] 
    att_ids = Attachment.search(cr, user, args, context=context) 
    record_ids = set(att.res_id for att in Attachment.browse(cr, user, att_ids, context=context)) 
    return [('id', 'in', list(record_ids))] 

'index_content'：fields.function（_get_index_content，fnct_search = _content_search，字符串= '索引內容'，類型=「文本「），

我得到了預期singleton candidat.base（1,2,3,4）作爲錯誤。

Answer 1

applicant_ids = self.pool.get('hr.applicant').search(cr, user, [('email_from', '=', self.browse(cr, user, ids, context=context).email_candidat)], context=context) 

如果ids是2個或更多ID的列表，則不起作用。瀏覽器將獲得2個條目的記錄集，其中您不能調用像email_candidat這樣的字段值。

嘗試搜索類似的所有電子郵件地址：

applicant_ids = self.pool.get('hr.applicant').search(cr, user, [('email_from', 'in', [x.email_candidat for x in self.browse(cr, user, ids, context=context)])], context=context) 

並可能使用一些線，使代碼更易讀。
