如果'update'是包含密钥数据存储区密钥的查询字符串,它是否会更新现有记录。我尝试这个,但继续添加新的记录/实体。请给我一些关于正确更新记录/实体的意见。

答案 0 :(得分:0)
当您知道密钥时,无需进行查询:只需在密钥上调用db.get()即可直接检索它,这比执行查询要快得多。
至于您每次创建新记录的原因,看起来您没有正确地将“更新”传递到您的页面。尝试记录查询字符串参数以查看出现了什么问题。

我终于自己回答了这个问题,感谢Nick Johnson对此的指导。 我无法将查询字符串url作为“字符串键”始终引发BadKeyError:无效的字符串键异常。
我尝试将这个'update'字符串作为隐藏字段放在html编辑表单上,这是有效的,因为'update'现在是一个有效的'字符串键'。
