[英]Magento cron job expression dynamically
i am trying to set up a cron job dynamically in my custom module. 我试图在我的自定义模块中动态设置cron作业。 but this do not save the job_code to cron_schedule table. 但这不会将job_code保存到cron_schedule表中。
<config>
<crontab>
<jobs>
<bookingreservation_summary>
<!--<schedule><cron_expr>*/5 * * * *</cron_expr></schedule>-->
<run><model>bookingreservation/observer::sendBookingSummaryEmail</model></run>
</bookingreservation_summary>
</jobs>
</crontab>
</config>
And the cron_expr is commented, because i am generating it from configurations. 并且对cron_expr进行了注释,因为我是从配置生成它的。 and this saves expression and model in config_data table like, 这会将表达式和模型保存在config_data表中,例如,
path: crontab/jobs/process_bookingreservation_summary/schedule/cron_expr
value: 0 17 * * *
path : crontab/jobs/process_bookingreservation_summary/run/model
value : bookingreservation/observer::sendBookingSummaryEmail
this class executes and saves into config_data 此类执行并保存到config_data中
class ABC_Bookingreservation_Model_Config_Backend_Cron extends Mage_Core_Model_Config_Data
{
const CRON_STRING_PATH = 'crontab/jobs/process_bookingreservation_summary/schedule/cron_expr';
const CRON_MODEL_PATH = 'crontab/jobs/process_bookingreservation_summary/run/model';
/**
* Cron settings after save
*
* @return Mage_Adminhtml_Model_System_Config_Backend_Log_Cron
*/
protected function _afterSave()
{
$enabled = $this->getData('groups/booking_summary/fields/enabled/value');
$time = $this->getData('groups/booking_summary/fields/time/value');
$frequncy = $this->getData('groups/booking_summary/fields/frequency/value');
$frequencyDaily = Mage_Adminhtml_Model_System_Config_Source_Cron_Frequency::CRON_DAILY;
$frequencyWeekly = Mage_Adminhtml_Model_System_Config_Source_Cron_Frequency::CRON_WEEKLY;
$frequencyMonthly = Mage_Adminhtml_Model_System_Config_Source_Cron_Frequency::CRON_MONTHLY;
if ($enabled)
{
$cronDayOfWeek = date('N');
$cronExprArray = array(
intval($time[1]), # Minute
intval($time[0]), # Hour
($frequncy == $frequencyMonthly) ? '1' : '*', # Day of the Month
'*', # Month of the Year
($frequncy == $frequencyWeekly) ? '1' : '*', # Day of the Week
);
$cronExprString = join(' ', $cronExprArray);
}
else{
$cronExprString = '';
}
try
{
Mage::getModel('core/config_data')
->load(self::CRON_STRING_PATH, 'path')
->setValue($cronExprString)
->setPath(self::CRON_STRING_PATH)
->save();
Mage::getModel('core/config_data')
->load(self::CRON_MODEL_PATH, 'path')
->setValue((string) Mage::getConfig()->getNode(self::CRON_MODEL_PATH))
->setPath(self::CRON_MODEL_PATH)
->save();
}
catch (Exception $e)
{
Mage::throwException(Mage::helper('adminhtml')->__('Unable to save the cron expression.'));
}
}
} }
can any one help where is issue with my code, because whenever i run cron.php through browser cron_scedule table updates, but do not save job_code from this job. 谁能帮我解决我的代码问题,因为每当我通过浏览器运行cron.php时,cron_scedule表就会更新,但不要保存此作业中的job_code。
path: crontab/jobs/bookingreservation_summary/schedule/cron_expr
instead of: path: crontab/jobs/process_bookingreservation_summary/schedule/cron_expr
试试这个: path: crontab/jobs/bookingreservation_summary/schedule/cron_expr
代替: path: crontab/jobs/process_bookingreservation_summary/schedule/cron_expr
if you don't solve look at how it works the cron settings for sitemap module ( it does the same you want to achieve ) 如果您不解决,请查看站点地图模块的cron设置如何工作(它可以实现您想要的效果)
Uncomment the following line in your code and see whether it works. 取消注释代码中的以下行,并查看其是否有效。
<!--<schedule><cron_expr>*/5 * * * *</cron_expr></schedule>-->
I think this may work....Let me know if it does. 我认为这可能有效。...让我知道是否可行。
