Extension Cron Job

[stan911]

Is it possible to add a cron job to an extension and triggered automatically when that extension is installed/setup on an app?

I could not find any related information neither in the documentation nor the extension example provided by you guys.

@stan911 - it works the other way around, from an extension you can hook into an existing cron job.
Can you explain what you are after ?

The target is as follows:
- build an extra functionality, as an extension, in order to make it portable;
- that extension will allow access to some statistics;
- the statistics should be generated hourly, by running a cron job;

@stan911 - We do have a hourly cron job, so from your extension, you can hook into it, as follows:

Yii::app()->hooks->addAction('console_command_hourly_after_process', function(){
    // do here your hourly work.
});

That's great. Thank you for the hint.
Is there a documentation regarding hooks and how to use them in general?

For example in this case, I'm wondering where will I use this? In the file ExtensionExt.php, in function run() ? If not there, where exactly?

Our system is inspired from wordpress'es one, see: https://codex.wordpress.org/Glossary#Action and https://codex.wordpress.org/Glossary#Filter
In wordpress you foo add_action() and add_filter() and in mailwizz you do Yii::app()->hooks->addAction(); and Yii::app()->hooks->addFilter();

In the file ExtensionExt.php, in function run() ?

Exactly.

I understand now. Thank you for the documentation link and further clarification.

One more question regarding this. After adding the hook as mentioned above, in the run() method of the main file of the extension, I've used within the callback function a method from a model as follows:

Yii::app()->hooks->addAction('console_command_hourly_after_process', function(){
Model::staticMethodName();
});

But it seems not to be triggered or working. Do you have any further hint on this, or how to test the cronjob if it takes this into account ? the extension is installed and enabled properly.

 

[twisted1919]

That looks correct. You might want, before calling Model::staticMethod to also import the model in the current scope

Yii::import('ext-your-extension.common.models.*');
Model::staticMethod();

 

[stan911]

It doesn't seem to get triggered. Any advice on how to debug this?
