I am trying to make a custom module to run a cron job to assign products to categories.

I am however missing something, and I keep getting errors, and the cron job shows up, but doesn't work.

/public_html/app/code/local/Firmname/Catcron/etc/config.xml

<?xml version="1.0"?>
<config>
    <modules>
        <Firmname_Catcron>
            <version>1.0</version>
        </Firmname_Catcron>
    </modules>

    <global>
        <models>
            <firmname_catcron>
                <class>Firmname_Catcron_Model</class>
            </firmname_catcron>                         
        </models>
    </global>

    <crontab>
        <jobs>
            <firmname_catcron>
                <schedule><cron_expr>*/5 * * * *</cron_expr></schedule>
                <run><model>Firmname_catcron/observer::crontask</model></run>
            </firmname_catcron>
        </jobs>
    </crontab>
</config>

/public_html/app/code/local/Firmname/Catcron/Model/Observer.php

<?php

class Firmname_Catcron_Model_Observer {
  public function crontask() {
        // code
    }
}

/public_html/app/etc/modules/Firmname_Catcron.xml

<?xml version="1.0"?>
<config>
  <modules>
    <Firmname_Catcron>
      <active>true</active>
      <codePool>local</codePool>
    </Firmname_Catcron>
  </modules>
</config>

The error:

---EXCEPTION--- Mage_Core_Exception: Invalid callback: Model for Firmname_catcron/observer::crontask does not exist in /var/www/mysite.com/public_html/app/Mage.php:598 Stack trace:

8 /var/www/mysite.com/public_html/cron.php(83): Mage::dispatchEvent('default')

9 {main}

I really hope someone has an idea as to why I am struggling so much to get my module to work!

Your alias for model is firmname_catcron and you call the cron with

<run><model>Firmname_catcron/observer::crontask</model></run>

I guess the uppercase F of Firmname instead of firmname could be the source of your issue.

Please, try with :

<run><model>firmname_catcron/observer::crontask</model></run>
  • That was the solution in my case! I can't believe i missed that one. Many thanks for your help! – user1765065 Dec 18 '19 at 13:54
