Question

I got a problem loading a second model handling a database with a module.
I got 1 controller ValidateController and 2 Models Main that extends Mage_Core_Controller_Front_Action so I can’t communicate with the database, and Log that communicates with the database.

When I call $log = Mage::getModel('modulex/log'); it is fine it gives me the correct path for with get_class($log) but when I call $log->load($params['id']); it fails giving me this error:

Warning: include(Companyx/Modulex/Model/Resource/Main.php) [function.include]: failed to open stream: No such file or directory

I don’t see why it gives me this error, it should call Resource/Log.php that exists.

I show you my config.xml

<frontend>
    <routers>
        <modulex>
            <use>standard</use>
            <args>
                <module>Companyx_Modulex</module>
                <frontName>modulex</frontName>
            </args>
        </modulex>
    </routers>
</frontend>
<global>
    <models>
        <modulex>
            <class>Companyx_Modulex_Model</class>
            <resourceModel>modulex_resource</resourceModel>
        </modulex>
        <modulex_resource>
            <class>Companyx_Modulex_Model_Resource</class>
            <entities>
                    <log>
                            <table>companyx_modulex_logs</table>
                    </log>
            </entities>
        </modulex_resource>
    </models>
</global>

Thank you for your help !

==== EDIT SOLUTION ====
Create /resource/Main.php with this code

class Companyx_Modulex_Model_Resource_Main extends Mage_Core_Model_Resource_Db_Abstract
{
    protected function _construct()
    {
        $this->_init('modulex/log', 'id');
    }
}

My mistake was doing $this->_init('modulex/main', 'id');.

The error message that you are receiving i reasonably clear, the resource model isn’t found. Magento splits models into what is essentially a 2 layer system. One layer for dealing with business logic and the other layer for dealing with persistence / database interaction. When you call load on your model, this is proxied off to the resource model specified for you class. In your configuration this resource is being set-up as Companyx_Modulex_Model_Resource_Main.php, but you seemingly don’t have a file in the location the class is supposed to be defined – app/code/{codepool}/Companyx/Modulex/Model/Resource/Main.php.
