python – 扭曲的MySQL adbapi返回字典

[name: 'Bob',phone_number: '9123 4567']

默认返回元组.

['Bob','9123 4567']

对于简单的Python& MySQL我们可以使用MySQLdb.cursors.DictCursor.但如何使用扭曲的adbapi

UPD：我解决了,但我认为应该有更好的方法.我的解决方案：只需覆盖adbapi.ConnectionPool类的* _runInteraction *方法.

class MyAdbapiConnectionPool(adbapi.ConnectionPool):
def _runInteraction(self,interaction,*args,**kw):
    conn = self.connectionFactory(self)
    trans = self.transactionFactory(self,conn)
    try:
        result = interaction(trans,**kw)
        if(result and isinstance(result[0],(list,tuple))):
            colnames = [c[0] for c in trans._cursor.description]
            result = [dict(zip(colnames,item)) for item in result]         
        trans.close()
        conn.commit()
        return result
    except:
        excType,excValue,excTraceback = sys.exc_info()
        try:
            conn.rollback()
        except:
            log.err(None,'Rollback failed')
        raise excType,excTraceback
