Overriding Enterprise Adminhtml block

Question

I've some troubles while trying to override a Enterprise Adminhtml's block.

Here is the Block that I want to override :

app/code/core/Enterprise/Reward/Block/Adminhtml/Customer/Edit/Tab/Reward/Management/Upgrade.php

Here is the top of my config.xml :

<?xml version="1.0" encoding="UTF-8"?>
<config>
    <modules>
        <Myself_Reward>
            <version>0.1.0</version>
            <depends>
                <Enterprise_Reward/>
            </depends>
        </Myself_Reward>
    </modules>
    <global>
        <blocks>
            <adminhtml>
                <enterprise_reward>
                    <rewrite>
                        <customer_edit_tab_reward_management_update>Myself_Reward_Customer_Edit_Tab_Reward_Management_Update</customer_edit_tab_reward_management_update>
                    </rewrite>
                </enterprise_reward>
            </adminhtml>
        </blocks>

And the file I've created : app/code/local/Myself/Reward/Block/Adminhtml/Customer/Edit/Tab/Reward/Management/Update.php :

class Myself_Reward_Customer_Edit_Tab_Reward_Management_Update
extends Enterprise_Reward_Block_Adminhtml_Customer_Edit_Tab_Reward_Management_Update
{
    protected function _prepareForm(){
        DIE("I'll KILL YOU");
    }
}

But I didn't see my sweet message... What do I wrong ?

Answer 1

I'm not familiar with EE but I reckon your overwrite should be:

<blocks>
    <reward>
        <rewrite>
            <customer_edit_tab_reward_management_update>Myself_Reward_Customer_Edit_Tab_Reward_Management_Update</customer_edit_tab_reward_management_update>
        </rewrite>
    </reward>
</blocks>

Basically the first node under <blocks> should match the first node declared under <blocks> in app/code/core/Enterprise/Reward/etc/config.xml

Answer 2

This should be your block declaration in config file :

<blocks>
    <myself_reward>
        <class>Myself_Reward_Block</class>
    </myself_reward>
    <enterprise_reward>
        <rewrite>
            <adminhtml_customer_edit_tab_reward_management_update>Myself_Reward_Block_Customer_Edit_Tab_Reward_Management_Update</adminhtml_customer_edit_tab_reward_management_update>
        </rewrite>
    </enterprise_reward>
</blocks>

And, your class name should be Myself_Reward_Block_Customer_Edit_Tab_Reward_Management_Update, not Myself_Reward_Customer_Edit_Tab_Reward_Management_Update

Answer 3

<?xml version="1.0" encoding="UTF-8"?>
<config>
<modules>
    <Myself_Reward>
        <version>0.1.0</version>            
    </Myself_Reward>
</modules>    
<global>
    <blocks>
        <myself_reward>
            <class>Myself_Reward_Block</class>
        </myself_reward>
        <enterprise_reward>
            <rewrite>   
                <adminhtml_customer_edit_tab_reward_management_update>      Myself_Reward_Block_Adminhtml_Customer_Edit_Tab_Reward_Management_Update</adminhtml_customer_edit_tab_reward_management_update>
            </rewrite>
        </enterprise_reward>
    </blocks>
</global>
</config>

Make sure to include, Enterprise_Reward_Block_Adminhtml_Customer_Edit_Tab_Reward_Management_Update in your local update.php file

Answer 4

I've make a mix of all of them and add some things and now It works.

Here is what I did :

My config.xml looks like that :

<?xml version="1.0" encoding="UTF-8"?>
<config>
    <modules>
        <Myself_Reward>
            <version>0.1.0</version>
            <depends>
                <Enterprise_Reward/>
            </depends>
        </Myself_Reward>
    </modules>
    <global>
        <blocks>
            <myself_reward>
                <class>Myself_Reward_Block</class>
            </myself_reward>
            <enterprise_reward>
                <rewrite>
<adminhtml_customer_edit_tab_reward_management_update>Myself_Reward_Block_Adminhtml_Customer_Edit_Tab_Reward_Management_Update</adminhtml_customer_edit_tab_reward_management_update>
                </rewrite>
            </enterprise_reward>
        </blocks>

My Upload.php :

<?php
require_once ('Enterprise/Reward/Block/Adminhtml/Customer/Edit/Tab/Reward/Management/Update.php');
class Myself_Reward_Block_Adminhtml_Customer_Edit_Tab_Reward_Management_Update
    extends Enterprise_Reward_Block_Adminhtml_Customer_Edit_Tab_Reward_Management_Update
{
    protected function _prepareForm(){
        DIE("I'll KILL YOU");
    }
}

My Upload.php file is inside :

app/code/local/Myself/Reward/Block/Adminhtml/Customer/Edit/Tab/Reward/Management/
