Magento - Override/extend Ebizmarts_SagePaySuite_Model_Api_Payment model class

Question

I am trying to override/extend the Ebizmarts SagePay Suite Ebizmarts_SagePaySuite_Model_Api_Payment model class

My module looks like this:

etc/modules/Sulman_ModifySagePay.xml

<?xml version="1.0"?>
<config>
    <modules>
        <Sulman_ModifySagePay>
            <active>true</active>
            <codePool>local</codePool>
            <version>1.0</version>
            <depends>
                <Ebizmarts_SagePaySuite />
            </depends>
        </Sulman_ModifySagePay>
    </modules>
</config>

app/code/local/Sulman/ModifySagePay/etc/config.xml

<?xml version="1.0"?>
<config>
    <modules>
        <Sulman_ModifySagePay>
            <version>0.0.1</version>
        </Sulman_ModifySagePay>
    </modules>
    <global>
        <models>
            <sagepaysuite>
                <rewrite>
                    <api_payment>Sulman_ModifySagePay_Model_Api_Payment</api_payment>
                </rewrite>
            </sagepaysuite>
        </models>
    </global>
</config>

app/code/local/Sulman/ModifySagePay/Model/Api/Payment.php

<?php

class Sulman_ModifySagePay_Model_Api_Payment extends Ebizmarts_SagePaySuite_Model_Api_Payment {

    public function _construct(){
        Mage::log('in my construct()', null, 'Sulman.log');
    }

    public function requestPost($url, $data, $returnRaw = false) {
        Mage::log('in my requestPost()', null, 'Sulman.log');
    }
}

Nothing gets logged and this gives me errors on the checkout page because:

When I check to see if it is instantiated it returns false (if I disable my module it returns the Ebizmarts_SagePaySuite_Model_Api_Payment object):

var_dump(Mage::getModel('sagepaysuite/api_payment'));

Other calls to this model throughout the site also fail.

I'm a little confused as it seems my rewrite is working correctly but it can't seem to find my new model class.

Anyone have any ideas where I'm going wrong?

Thanks

What are you trying to achieve? I think you should not rewrite Ebizmarts_SagePaySuite_Model_Api_Payment, instead focus on the child classes like Ebizmarts_SagePaySuite_Model_SagePayDirectPro. If you can tell me what you want to achieve I can help you. — Pablo

In your app/code/local/Sulman/ModifySagePay/etc/config.xml in the <models></models> section you need to define where your models are located:


<models>
    <modifysagepay>
        <class>Sulman_ModifySagePay_Model</class>
    <modifysagepay>
</models>
