Install script doesn't execute

Question

I'm trying to create a new attribute, but my install script does not run.

etc/config.xml

<modules>
 <Namespace_ShippingPrices>
 <version>0.1.0</version>
 </Namespace_ShippingPrices>
</modules>
<global>
 ...
 <resources>
 <namespace_shippingprices_setup>
 <setup>
 <module>Namespace_ShippingPrices</module>
 <class>Mage_Eav_Model_Entity_Setup</class>
 </setup>
 </namespace_shippingprices_setup>
 </resources>
</global>

sql/namespace_shippingprices_setup/install-0.1.0.php

<?php
/* @var $installer Mage_Eav_Model_Entity_Setup */
$installer = $this;
$entityType = Mage_Catalog_Model_Product::class;
$productGroup = 'Prices';
$attributes = [
 'namespace_shipping_price' => [
 'type' => 'decimal',
 'label' => 'Shipping costs',
 ]
];
foreach ($attributes as $attributeName => $attribute) {
 $createdAttribute = $installer->addAttribute(
 $entityType,
 $attributeName,
 [
 'backend_type' => $attribute['type'],
 'label' => $attribute['label'],
 'group' => $productGroup,
 'user_defined' => true,
 'required' => false,
 ]
 );
}

I can't find anything in logs and also in core_resource the module is not available.

• Tim Cieplowski: Do you see the module in Configuration > Advanced?
• Paul: Yes, I can see the module in there

Answer 1

Seems I have a totally different issue. When changing app/code/core/Mage/Core/Model/App.php:424

if (!$this->_config->loadModulesCache()) {

To

if ($this->_config->loadModulesCache()) {

It does load. So I'm going to find out why my cache doesn't clear.

• Tim Cieplowski: It is typically advised to manually clear cache after deploying a code change.
