Overwriting mage core create.php

Question

I'm attempting to overwrite adminhtml/model/sales/order/create.php, specifically public function initFromOrderItem.

Text output shows the function I've overwritten is not loading to the site.

In app/etc/modules/GoddessDelivers_QObugfux.xml

 <config>
     <modules>
         <GoddessDelivers_QObugfix> <!--  app/code/<codepool>/GoddessDelivers/QObugfix  -->
             <active>true</active>
             <codePool>local</codePool>
             <depends>
                 <Mage_Core />
             </depends>
         </GoddessDelivers_QObugfix>

     </modules>
 </config>

In app/code/local/GoddessDelivers/QObugfix/etc/config.xml

 <config>
     <modules>
         <GoddessDelivers_QObugfix>
             <version>0.0.0.1</version>
         </GoddessDelivers_QObugfix>
     </modules>
     <global>
         <adminhtml>
             <sales>
                 <order>
                     <rewrite>
                         <create>GoddessDelivers_QObugfix_Adminhtml_Model_Sales_Order_Create</create>
                     </rewrite>
                 </order>
             </sales>
         </adminhtml>
     </global>

 </config>

In app/code/local/GoddessDelivers/QObugfix/Adminhtml/Model/Sales/Order/Create.php:

 class GoddessDelivers_QObugfix_Adminhtml_Model_Sales_Order_Create
 extends Mage_Adminhtml_Model_Sales_Order_Create {
     public function initFromOrderItem(Mage_Sales_Model_Order_Item $orderItem, $qty = null)
     {

What am I doing wrong?

Answer 1

You are missing the <models> node in your config. Your node nesting also needs fixing.

<config>
    <modules>
         <GoddessDelivers_QObugfix>
             <version>0.0.0.1</version>
         </GoddessDelivers_QObugfix>
     </modules>
     <global>
         <models>
             <adminhtml>
                 <rewrite>
                     <sales_order_create>GoddessDelivers_QObugfix_Adminhtml_Model_Sales_Order_Create</rewrite>
                 </adminhtml>
             </models>
         </global> 
 </config>

1. Typo in file name app/etc/modules/GoddessDelivers_QObugfux.xml; probably you meant app/etc/modules/GoddessDelivers_QObugfix.xml
2. In file app/etc/modules/GoddessDelivers_QObugf*u*x.xml you should set a the module you're overwriting from as a dependency, so <depends><Mage_Adminhtml /></depends>
3. In config.xml the path is /config/global/models/adminhtml, so you should have:

<config>
  <global>
    <models>
      <adminhtml>
        <rewrite>
          <sales_order_create>GoddessDelivers_QObugfix_Adminhtml_Model_Sales_Order_Create</sales_order_create>
        </rewrite>
      </adminhtml>
    </models>
  </global>
</config>

4. The modes path is non-standard; should be code/local/GoddessDelivers/QObugfix/Model/Adminhtml/Sales/Order/Create.php and the class name should reflect the path.
