如何出口GAE数据到mysql

Question

我的 '学院' 模型数据是：

alt text http://omploader.org/vNG9zNw

我str_loader.py是：

class MySQLExporter(bulkloader.Exporter): 
    def output_entities(self, entity_generator): 
     conn = MySQLdb.connect(host='localhost',user='root',passwd='root',db='test',charset="utf8") 
     c = conn.cursor() 
     for entity in entity_generator: 
      c.execute("INSERT INTO haha (a,b) VALUES (%s, %s)", 
        (entity['cid'], entity['name'])) 

class Mysql_download(MySQLExporter): 
    def __init__(self): 
     MySQLExporter.__init__(self,'College', 
            [ 
            ('cid', str,None), 
            ('name', lambda x: unicode(x, 'utf8'),None), 
            ]) 

exporters = [Mysql_download] 

，它运行成功：

但它没有向mysql插入数据：

感谢

更新

现在已确定：

class MySQLExporter(bulkloader.Exporter): 
    def output_entities(self, entity_generator): 
     conn = MySQLdb.connect(host='localhost',user='root',passwd='root',db='test',charset="utf8") 
     c = conn.cursor() 
     for entity in entity_generator: 
      c.execute("INSERT INTO haha (a,b) VALUES (%s, %s)", 
        (entity['cid'], entity['name'])) 
     conn.commit()

尝试调用.commit（）加载实体后，连接上。
