System log error

Question

I followed this tutorial, from this site: http://coding.smashingmagazine.com/2012/03/01/basics-creating-magento-module/ I have to mentioned that I have the same code as in the site. The problem is when I create/update o product I got in var/log/system.log this error:

"2013-12-02T08:36:36+00:00 ERR (3): Warning: include(C:\xampp\htdocs\mage\magento\includes\src\Mage_Smashingmagazine_Logproductupdate_Model_Observer.php): failed to open stream: No such file or directory  in C:\xampp\htdocs\mage\magento\includes\src\Varien_Autoload.php on line 93

Answer 1

Some point need to take care while creating config xml in Magento.

1. Always use <Namesapce_Modulename> not <NameSpace_ModuleName> as it will not work when you create object using 'namesapce/modulename' as Magento try to find the class like Namespace_Modulename_Model_Class not NameSpace_ModuleName_Model_Class.

2. In your case either change your Namespace and Moduel name properly or use the below config.xml

   <?xml version="1.0" encoding="UTF-8"?> <config> <modules> <Smashingmagazine_Logproductupdate> <version>0.0.1</version> </Smashingmagazine_Logproductupdate> </modules> <global> <events> <catalog_product_save_after> <observers> <smashingmagazine_logproductupdate> <class>smashingmagazine_logproductupdate/observer</class> <method>logUpdate</method> <type>singleton</type> </smashingmagazine_logproductupdate > </observers> </catalog_product_save_after> </events> </global> </config>

3. and change the folder name accordingly.

Answer 2

Add this in your config.xml inside the <global> tag

<models>
    <smashingmagazine_logproductupdate>
        <class>SmashingMagazine_LogProductUpdate_Model</class>
    </smashingmagazine_logproductupdate>
</models>

and clear the cache
