后端配置中的 magento cron [英] magento cron in backend configuration

问题描述

所以我知道如何使用 config.xml crontab 内容设置 cron:

So I know how to setup a cron using the config.xml crontab stuff:

<crontab>
    <jobs>
        <millena_export_send_all>
            <schedule><cron_expr>* * * * *</cron_expr></schedule>
            <run><model>millena_export/observer::exportOrderData</model></run>
        </millena_export_send_all>
    </jobs>
</crontab>

但让我感到困惑的是如何使 cron_expr 成为后端中可以更改的设置(每 5 分钟、每 10 分钟等).我想我可以使用 backend_model 然后在 after_save 方法中我可以做 setStoreConfig('path/to/schedule/cron_expr', '*/5 * * * *') 或类似的东西，它会保存在缓存.我的想法正确吗?有没有更好的方法来做到这一点?

But what I am confused about is how to make that cron_expr a setting in the backend that can be changed (every 5 minutes, every 10 minutes, etc). I am thinking I can use a backend_model and then in an after_save method I can do setStoreConfig('path/to/schedule/cron_expr', '*/5 * * * *') or something to that sort and it will save in the cache. Is my thinking correct? Is there a better way to do this?

推荐答案

不涉及自定义后端模型的更好解决方案.

A better solution that doesn't involve a custom backend model.
