django执行sql根据字段显示对应的数据

L = []
cursor.execute(sql)
desc = cursor.description  # 获取字段的描述，默认获取数据库字段名称
data_dict = [dict(zip([col[0] for col in desc], row)) for row in
             cursor.fetchall()]  # 列表表达式把数据组装起来
for online_dict in data_dict:    # 判断如果时间类型要转出字符串，后期碰到什么类型不能转的在加
    for key in online_dict:
        if type(online_dict[key]) in (datetime, pymysql.TIMESTAMP, pymysql.DATE,
                                      pymysql.TIME, YEAR):
            online_dict[key] = online_dict[key].strftime(
                "%Y-%m-%d %H:%M:%S")
        else:
            pass
    L.append(online_dict)
conn.commit()
cursor.close()
conn.close()
dic['code'] = '2'
dic['message'] = ''
dic['result'] = L
return HttpResponse(json.dumps(dic, ensure_ascii=False))
