Bottle框架SqlAlchemy類型錯誤：對象不可迭代

我正在嘗試使用瓶框架編寫REST api。我的基類CRUD有兩種方法。基本查詢執行查詢，get_values方法遍歷結果並返回數據。但我得到的對象不可迭代錯誤。Bottle框架SqlAlchemy類型錯誤：對象不可迭代

class InfluencerCrud(CrudObject): 
def base_query(self, db_session, request_params): 

    return db_session.query(Groups, GroupLeaders, Users) \ 
      .filter(GroupLeaders.id == Groups.group_leaders_id) \ 
      .filter(Users.id == GroupLeaders.users_id) 

def get_values(self, db_session, request_params, raw_result): 
    logging.error(raw_result) 
    for group, group_leader, user in raw_result: 
     data = as_dict(group, include_columns = ['clicks_estimated', 'completeness', 'cpc', 'created_at', 
               'description', 'guid','languages_id', 'name', 'registration_status', 
               'size', 'url', 'verticals_id']) 
     data['addresses_id'] = user.addresses_id 
     data['user'] = as_dict(user, include_columns = ["addresses_id", "created_at", "education_id", "email", 
                 "email_verified_at", "gender", "income_id", "marital_status_id", 
                 "name_first", "name_last", "phone", "status", "updated_at", "worK_status_id"]) 
     data['user']['race_id'] = [] 
     c = session.query(UserHasRace.race_id).filter(UserHasRace.user_id == user.id) 
     for r, in c: 
      data['user']['race_id'].append(r) 
     data['user']['children'] = [] 
     c = session.query(UserChildren).filter(UserChildren.user_id == user.id) 
     for r in c: 
      data['user']['children'].append(get_dict_obj(r)) 
     picurl = None 
     up = session.query(UserPicture).filter(UserPicture.id == user.pictures_id).first() 
     if up != None and up.file_name != None: 
      i = up.file_name.rfind('/') 
      picurl = linqia.system.config.avatars.s3_url + 'user_pictures/' + up.file_name[i + 1:] 
     data['user']['picture_url'] = picurl 
     return data

以下是錯誤

File "/home/linqia-api-internal/current/api-internal/source/influencers/influencer.py", line 42, in get_values [Tue Feb 14 20:41:10 2017] [error] [client ::1] for group, group_leader, user in raw_result: [Tue Feb 14 20:41:10 2017] [error] [client ::1] TypeError: 'Groups' object is not iterable

當我試圖打印的原始數據，我越來越引用到所有的三個對象。我只是沒有得到迭代他們。

任何幫助，將不勝感激，謝謝

有一個修復。我的get_values函數正在調用我正在做的每個查詢，因此，它是我所做的所有查詢（組，groublyaders，用戶）的一個元組。因此，我必須以元組的形式訪問它。
