During the past days we have had some problems when updating our Magento custom modules. Oddly, even though we created the mysql4-upgrade file and edited the config.xml with the new version, the upgrade script wouldn’t run. Why? We don’t know.
But we needed a quick solution because there was an important issue in the production server. We finally decided to create a custom setup script to edit one of the attributes. So here is how you can simulate the Magento module $setup from your custom script (I’m assuming that you’re creating your php script in the Mageto root directory.
Note that when you call the model/resourcemodel you need, you have to add the ‘core_setup’ parameter. If it is not added, then the script won’t work:
<?php require_once 'app/Mage.php'; umask(0); Mage::app('admin'); $setup = Mage::getResourceModel('catalog/setup', 'core_setup'); $setup->startSetup(); /** Do whatever you need to do here */ $setup->endSetup(); ?>
