I'm trying to extend the magento class Mage_Cms_Block_Block. I've got my module active. I think the reason why its failing is to do with the config.xml.
<?xml version="1.0" encoding="UTF-8"?>
<config>
<modules>
<VisibleBlocks_ShowBlocks>
<!-- The version of our module, starting at 0.0.1 -->
<version>0.0.1</version>
</VisibleBlocks_ShowBlocks>
</modules>
<global>
<blocks>
<mage_cms>
<rewrite>
<cms_blocks>VisibleBlocks_ShowBlocks_Block_Border</cms_blocks>
</rewrite>
</mage_cms>
</blocks>
</global>
</config>
Can someone explain to me what the tags inside the global tags mean? Can the tags inside rewrite be called anything?
OK seems that asking the questions made it clearer to me. Hope this hasn't a waste of time for anyone. 'mage_cms' should be 'cms' as that is the module i'm extending and 'cms_blocks' should be 'block'.
i have explain the details,please check
<global>
<blocks>
<cms><!--module name of rewrite class mage_cms -->
<rewrite>
<!-- file path of Block of app/code/core/mage/cms/block.php -->
<blocks>VisibleBlocks_ShowBlocks_Block_Border</blocks>
</rewrite>
</cms>
</blocks>
</global>
<config>
<global>
<blocks>
<cms>
<rewrite>
<block>VisibleBlocks_ShowBlocks_Block_Cms_Block</block>
</rewrite>
</cms>
</blocks>
</global>
</config>
With these tags, we say we will configure a block of Magento’s core called cms and we will rewrite () the « block » block of this module
Also make sure your module is active & being displayed in system/config/Advanced

I am overwriting Mage_Catalog_Model_Resource_Product_Collection class to Namespace_Catalog_Model_Resource_Product_Collection to overwrite a protected function(_preparePriceExpressionParameters).
this is code I wrote in config.xml to overwrite this class file.
<models>
<catalog>
<rewrite>
<resource_product_collection>Namespace_Catalog_Model_Resource_Product_Collection</resource_product_collection>
</rewrite>
</catalog>
</models>
but it does not work, then I changed the code as below but this also does not work.
<models>
<catalog_resource_product>
<rewrite>
<collection>Namespace_Catalog_Model_Resource_Product_Collection</collection>
</rewrite>
</catalog_resource_product>
</models>
can any one have the idea what I made wrong.
the node above the rewrite has to match the <resourceModel> from the model you want to overwrite, so:
<global>
<models>
<namespace_catalog>
<class>Namespace_Catalog_Model</class>
</namespace_catalog>
<catalog_resource>
<rewrite>
<product_collection>Namespace_Catalog_Model_Resource_Product_Collection</product_collection>
</rewrite>
</catalog_resource>
</models>
</global>
The last one should be fine. Maybe another module is already overwriting Mage_Catalog_Model_Resource_Product_Collection which conflicts with your overwrite.
I would like to introduce my own entities into particular Magento module namespaces for example I might want to be able to call
Mage::getModel('catalog/brand')->load(1);
Brand is not currently a model included in the catalog module. I don't want to modify core files nor do I want to hack the core by just adding a Mage folder to the local directory.
I was thinking perhaps syntax inside of my namespaces config file similar to this:
<models>
<catalog>
<args>
<modules>
<AJW_Catalog before="Mage_Catalog">AJW_Catalog</AJW_Catalog>
</modules>
</args>
</catalog>
<ajw_catalog>
<class>AJW_Catalog_Model</class>
</ajw_catalog>
</models>
but it does not seem to work.
Does anyone know how this can be accomplished?
Maybe possible with some trickery, but not officially supported, and generally a bad idea. The before= syntax you've used only works for the routers node. There's no framework code to let you do what you're trying to do. Also, there's a strong bias in the Magento framework code towards individual modules "owning" their namespace/package name. Defining new models in an existing namespace (catalog) introduces the theoretical possibility that your code may conflicts with a future version of Magento's code.
This may be a possible fix (brain fart)
Create a module named Customnamespace_Catalog and then just rewrite the catalog module with a node that doesnt exist in the default mage module:
<?xml version="1.0"?>
<config>
<modules>
<Namespace_Catalog>
<version>0.1.0</version>
</Namespace_Catalog>
</modules>
<global>
<models>
<catalog>
<rewrite>
<brand>Namespace_Brand_Model_Brand</brand>
</rewrite>
</catalog>
</models>
</global>
</config>
Followed by an additional module:
<?xml version="1.0"?>
<config>
<modules>
<Namespace_Brand>
<version>0.1.0</version>
</Namespace_Brand>
</modules>
<global>
<models>
<brand>
<class>Namespace_Brand_Model</class>
</brand>
</models>
</global>
</config>
This will allow you to call Mage::getModel('catalog/brand')
echo get_class(Mage::getModel('catalog/brand'); // Namespace_Brand_Model_Brand
I'm try to overriding Mage_Core_Block_Messages
I'm create module
Mycompany_Core.xml and save in path app/etc/modules/Mycompany_Core.xml
<?xml version="1.0"?>
<config>
<modules>
<Mycompany_Core>
<active>true</active>
<codepool>local</codepool>
</Mycompany_Core>
</modules>
</config>
next I was create in app/code/local/Mycompany/Core/Block/Messages.php
class Mycompany_Core_Block_Messages extends Mage_Core_Block_Messages
{
//update method
}
and add config.xml in app/code/local/Mycompany/Core/etc/config.xml
<config>
<modules>
<Mycompany_Core>
<version>0.0.1</version>
</Mycompany_Core>
</modules>
<global>
<blocks>
<core>
<rewrite>
<messages>Softdk_Core_Block_Messages</messages>
</rewrite>
</core>
</blocks>
</global>
</config>
But i don't see any result on frontend, I'm wonder where I'm make mistake.
Thx for help.
There are two things that caught my eye.
1.) In your module's registration file, it should be codePool and not codepool (as also said by David in comments)
2.) What is Softdk? If that is the name of your new module, then replace Mycompany with Softdk everywhere in your module.
Clear cache and voila!
I've gotten quite used to overwriting magento's frontend layout files, so I thought it would be easy to overwrite a phtml template in the admin panel - but I've gotten nowhere in the last six hours. All tutorials I've found so far are concentrating on creating a controller, but I only need to overwrite two phtml files since I only want to change the dispaly of the ordered items a little.
Specifically I want to overwrite the default/template/sales/order/view/items.phtml, normally i'd just match that path in my design folder of my own module and call it a day.
I can overwrite the block php file in Mage/Adminhtml/Sales/Order/View/Items.php through my config.xml:
<config>
...
<global>
...
<blocks>
...
<adminhtml>
<rewrite>
<sales_order_view_items>MyCompany_MyModule_Block_Adminhtml_Sales_Order_View_Items</sales_order_view_items>
</rewrite>
</adminhtml>
</blocks>
...
</global>
...
</config>
How can I tell Magento to use my phtml file in design/adminhtml//default/sales/order/view/items.phtml ?
Shouldn't these lines in my config.xml work?
<config>
...
<adminhtml>
<layout>
<updates>
<my_module>
<file>order_list.xml</file>
</my_module>
</updates>
</layout>
</adminhtml>
...
</config>
Any help is really appreciated! I really hope I've just overlooked something...
What you could do is put your custom module before Mage_Adminhtml
<admin>
<routers>
<adminhtml>
<args>
<modules>
<My_Module before="Mage_Adminhtml">My_Module_Adminhtml</My_Module>
</modules>
</args>
</adminhtml>
</routers>
</admin>
Then copy to your order_list.xml
<adminhtml_sales_order_view>
....
</adminhtml_sales_order_view>
from /app/design/adminhtml/default/default/layout/sales.xml
In order_list.xml you could now replace the block type and template file (phtml) location
Hi friends:
I have overrided some modules : "Enterprise/Pci/Model/Observer.php","Mage/Admin/Model/User.php","Mage/Admin/Model/Session.php","Mage/Admin/Model/Observer.php".
And configuration as follows(config.xml):
`<global>
<models>
<Pci>
<rewrite>
<observer>App_Pci_Model_Observer</observer>
</rewrite>
</Pci>
</models>
</global>`
....
`<global>
<models>
<Admin>
<rewrite>
<observer>App_Admin_Model_Observer</observer>
<session>App_Admin_Model_Session</session>
<user>App_Admin_Model_User</user>
</rewrite>
</Admin>
</models>
</global>`
but it doesn't work, my code is not run.
Any help is greatly appreciated.
The module names are case-sensitive. Instead of <Admin> use <admin>. Instead of <Pci> use <enterprise_pci>.
