如何在doctrine / symfony中设置MysQL变量(time_zone)?(How do I set a MysQL variable (time_zone) from within doctrine / symfony?)

我想知道如何在Symfony / Doctrine中将MySQL时区设置为UTC( SET time_zone = 'UTC' ),所以当我在查询中的DATETIME字段上调用UNIX_TIMESTAMP()函数时,它返回UTC unix时间而不是服务器时区的unix时间。

如何在每次连接时自动执行此操作,或者在时区有所不同的这些类型的查询之前手动执行此操作?

顺便说一下,我需要在MySQL查询中进行这种转换,而不是应用程序,所以我可以GROUP BY一个需要纪元时间的间隔。


I would like to know how I can set the MySQL time zone to UTC (SET time_zone = 'UTC') from within Symfony/Doctrine, so when I call a UNIX_TIMESTAMP() function on a DATETIME field in my query, it returns the UTC unix time and not unix time in the server's time zone.

How can I do this, either automatically upon every connection, or manually before these types of queries where the timezone makes a difference?

BTW, I need to do this conversion within the MySQL query and not the app so I can GROUP BY an interval that requires epoch time.

我没有意识到任何特定的实用程序,使这很容易。 出于我的目的,我只创建一个具有单个文件选择器input的局部视图。 在主视图中,我使用一个帮助器来渲染一个并使用一个AJAX动作链接供用户点击它将获得部分的另一个实例并添加它在第一个下面做DOM。 在这种情况下,用户必须单击“添加新文件”,然后再次单击以实际找到要上载的文件。

我不知道有任何方法可以让你在不使用插件的情况下在文件选择器对话框中选择多个文件。


I unaware of any particular utilities that make this easy. For my purposes, I just create a partial view that has the input for a single file picker. On the main view, I use a helper to render one and use an AJAX action link for the user to click on which will go and get another instance of the partial and add it do the DOM below the first one. In this case the user has to click 'Add New File' and then click again to actually locate the file to upload.

I'm not aware of any method that lets you select multiple files in the file picker dialog without using a plugin.
