使用数据库字段值与cakephp中的savefield相加值(Add up value using database field value with savefield in cakephp)

使用数据库字段值与cakephp中的savefield相加值(Add up value using database field value with savefield in cakephp)

我的问题很简单，但很难找到搜索引擎的答案。

我只想更新数据库中的字段，使用旧字段值来添加另一个值。 我现在正在使用以下内容：

$this->Advertisement->saveField('total_views', '(total_views + 1)', false);

但这给了我下一个查询：

UPDATE `advertisement` SET `total_views` = '(total_views +1)', `modified` = '2011-08-26 10:44:58' WHERE `advertisement`.`id` = 16

这是错的，它应该是：

UPDATE `advertisement` SET `total_views` = (total_views +1), `modified` = '2011-08-26 10:44:58' WHERE `advertisement`.`id` = 16

问题在于它在引号之间放置(total_views +1) 。

有没有人知道如何使这个工作？

my question is pretty simple but hard to find an answer for though search engines.

I simply want to update a field in the database, using that fields old value to add another value. I'm using the following at the moment:

$this->Advertisement->saveField('total_views', '(total_views + 1)', false);

But this gives me the next query:

UPDATE `advertisement` SET `total_views` = '(total_views +1)', `modified` = '2011-08-26 10:44:58' WHERE `advertisement`.`id` = 16

This is wrong and it should be:

UPDATE `advertisement` SET `total_views` = (total_views +1), `modified` = '2011-08-26 10:44:58' WHERE `advertisement`.`id` = 16

The problem is where it puts (total_views +1) between quotes.

Does anyone have an idea on how to get this working?

$this->Advertisement->updateAll( array('Advertisement.total_views' => 'Advertisement.total_views + 1'), array('Advertisement.id' => 1) ); $this->Advertisement->updateAll( array('Advertisement.total_views' => 'Advertisement.total_views + 1'), array('Advertisement.id' => 1) );
