I have created a modules:
app/code/local/MyStore/Welcome
And in this module, I have a controller like:
MyStore_Welcome_IndexController
From my current knowledge, I see at the beginning Magento load Mage_Cms_IndexController controller as the default controller.
Now I want to load MyStore_Welcome_IndexController controller as default.
How can I do that?
Update:
I've found a way to do using admin feature:
From the menu you chose: System/Configuration/Web:
You continue to choose: "Default Page" => "Default Web URL" to field the module:
You need to make sure that your controller extends Mage_Cms_IndexController and then override that default controller via the controller overloading method. In this method you will create a plugin as per usual, but you need to do the following:
add the declaration require_once() at the top with the relative path to the controller you're overloading. E.g. :
require_once 'Mage/Checkout/controllers/OnepageController.php';
class MyClass_OverloadedCheckout_Checkout_OnepageController extends Mage_Checkout_OnepageController
Create any class methods or properties that you may want to add in addition to the default.
in your config.xml add the following lines outside of the <global> node:
<frontend>
<routers>
<myclass_overloadedcheckout>
<use>standard</use>
<args>
<module>Myclass_OverloadedCheckout</module>
<frontName>OverloadedCheckout</frontName>
</args>
</myclass_overloadedcheckout>
</routers>
</frontend>
Something to remember - if you rewrite any default methods you need to return parent::{methodname} either before or after your injected functionality to ensure that the default behaviors continue to operate.
You should think again if you really want to do it because it is a huge change, but you could simply override the Mage_Cms_IndexController. How you can override a controller, you can find e.g. here.
Anyway, I would try to solve the problem another way. Maybe you can use the Event/Observer Pattern?

Can some configuration in the admin panel (or elsewhere) prevent a model rewrite from running?
This is the rewrite declaration in the module's config.xml:
<global>
<models>
<cataloginventory>
<rewrite>
<stock_item>My_Mod_CatalogInventory_Model_Stock_Item</stock_item>
</rewrite>
</cataloginventory>
</models>
</global>
The module is active - this is certain because other module code is running.
I overwrote the checkQuoteItemQty method from Mage_CatalogInventory_Model_Stock_Item, but it's checkQuoteItemQty from the parent class that is running, no idea why...
class My_Mod_CatalogInventory_Model_Stock_Item extends Mage_CatalogInventory_Model_Stock_Item
{
public function checkQuoteItemQty($qty, $summaryQty, $origQty = 0)
{
// this code is not running...
exit('hello there');
Step 1 to debugging any rewrite — attempt to manually instantiate an object from the class yourself, and ensure that your class is the one used.
$object = Mage::getModel('cataloginventory/stock_item');
var_dump(get_class($object));
If the above doesn't output My_Mod_CatalogInventory_Model_Stock_Item, check that your config.xml is correct, that your Item.php file is in the right folder, and finally, jump to the getGroupedClassName method and add enough debugging code to determine why Magento isn't seeing your rewrite.
I only need to add a method to the Mage_Core_Model_Abstract class.
For that, in my config.php I have
<models>
<mymodule>
<class>Mynamespace_Mymodule_Model</class>
</mymodule>
<core>
<rewrite>
<mage_core_model_abstract>Mynamespace_Mymodule_Model_Abstract</mage_core_model_abstract>
</rewrite>
</core>
</models>
It doesn't really work..
I know that there is a way of "overriding" by copying all the folder structure including the class file into my module, but I would like to know if there is a way to make it more fancy, within my module - something similar as above..
You can only rewrite classes that you instantiate directly, from config.xml.
The various values in config.xml are used when creating an object through a factory (e.g. Mage::getModel($class), Mage::getSingleton($class), Mage::helper($class), etc). The value of the $class argument is used to translate catalog/product into Mage_Catalog_Model_Product.
This means it's impossible to rewrite (in the Magento sense) classes that are used as superclasses, including abstract classes (by definition).
If you want to redefine any class that's used as a superclass, then you'll need to place a file in the correct place further up the include path. In this case, you'd need to make a file in app/code/local/Mage/Core/Model/Abstract.php.
I tried to override Pdf classes for making changes toInvoice/Shipment/Creditmemo pdf but it doesnt seem to reflect.
I created a module with following in the Mymodule/etc/config.xml
<config>
<modules>
<Mymodule_Printtemplates>
<version>0.1.0</version>
</Mymodule_Printtemplates>
</modules>
<global>
<models>
<sales>
<rewrite>
<order_pdf_abstract>Mymodule_Printtemplates_Model_Order_Pdf_Abstract</order_pdf_abstract>
<order_pdf_invoice>Mymodule_Printtemplates_Model_Order_Pdf_Invoice</order_pdf_invoice>
<order_pdf_creditmemo>Mymodule_Printtemplates_Model_Order_Pdf_Creditmemo</order_pdf_Creditmemo>
<order_pdf_shipment>Mymodule_Printtemplates_Model_Order_Pdf_Shipment</order_pdf_shipment>
</rewrite>
</sales>
</models>
</global>
Then I created following Model classes in Mymodule/models/
as Abstract.php, Invoice.php, Shipment.php, Creditmemo.php
abstract class Mymodule_Printtemplates_Model_Order_Pdf_Abstract extends Mage_Sales_Model_Order_Pdf_Abstract
class Mymodule_Printtemplates_Model_Order_Pdf_Invoice extends Mymodule__Printtemplates_Model_Order_Pdf_Abstract { ... functions here ...}
class Mymodule_Printtemplates_Model_Order_Pdf_Shipment extends Mymodule__Printtemplates_Model_Order_Pdf_Abstract{ ... functions here ...}
class Mymodule_Printtemplates_Model_Order_Pdf_Creditmemo extends Mymodule__Printtemplates_Model_Order_Pdf_Abstract{ ... functions here ...}
The module is enabled - I have checked it through System>Configuration>Admin>Advanced but it doesn't seem to reflect the changes
On the other-hand, if I copy paste Mage/Sales/Model/Order/Pdf/*.php into local and change, changes are reflected. I know this is not a recommended method but the method via rewriting classes doesnt seem to work.
Any help for the first method via class rewrite would be appreciated.
Thanks,

The real problem was a Syntax in error in etc/config.xml [see Capital C in ending tag]
Mymodule_Printtemplates_Model_Order_Pdf_Creditmemo
I used the following to debug the issue: Drop this in the bottom of your index.php, similar to Alans Module List but a quick code copy/paste approach. Remember all of Magento's XML's get combined into one XML tree.
header("Content-Type: text/xml"); die(Mage::app()->getConfig()->getNode()->asXML());
Taken from the answers of: How do I know whether my Config.xml file is working in Magento?
Here are a couple of things that I am seeing.
What are the file paths to each of your overridden files? They should be: Mymodule/Printtemplates/Model/Order/Pdf/Invoice.php, for example. The class name should match the file name.
Rewrites do not affect abstract classes, unless the abstract class is called with a factory method (not recommended). The way that a rewrite works is through the factory methods (Mage::getModel('')). Using the factory method allows Magento to look through the system to see if another class is needing to be used. However, when a class is hard-referenced (e.x. Mage_Sales_Model_Order_Pdf_Abstract), it does not go through the factory method, and thus no rewrites will occur on that.
I would consider making each of your classes extend their original class (e.x. Mage_Sales_Model_Order_Pdf_Invoice, etc). If you have extra common functions, you would possibly put those into a Helper.
To see if the code is even being called, put a known code error in the file. PHP will complain, and that tells you that your file is being loaded.

First day with Magento.
Trying to extend an admin controller "Mage_Adminhtml_Sales_Order_EditController"
with "SF_Teams_Adminhtml_Sales_Order_EditController"
I've been trying Google examples for 5 hours now, and my brain is bleeding...
Can some one please help with the config.xml code? (means, do it for me)
Thanks a lot.
For general information on adding routes to Adminhtml you can refer to Mage_Widget config.xml.
You need to do two things to accommodate standard route collection in Magento: 1) add a directory to the list of directories for a module's controller and 2) match the route pattern by naming your controller class and action just as the original is defined.
Necessary config:
<admin>
<routers>
<adminhtml>
<args>
<modules>
<your_dir before="Mage_Adminhtml">SF_Teams_Adminhtml</your_dir>
</ ... >
See the standard router's collectRoutes() method as a reference.
Then in your controller file at SF/Teams/controllers/Adminhtml/Sales/Order/EditController.php,
you may or may not extend from the original class and override (determined by what you need from the parent class). If so, you need to include the original class file before the class definition, as the system cannot autoload the original file.
OK, so this is leading on from another question I asked here recently. Basically, I want to extend the Mage_Catalog_Model_Resource_Eav_Mysql4_Product_Collection class, so I can add some extra filters for the product collections that can be re-used throughout my store (such as best-selling). This is meant to replace the following code, which I currently use, which is in my template.phtml file:
$_bs_productCollection = Mage::getResourceModel('reports/product_collection')
->addAttributeToSelect('name')
->addAttributeToFilter('visibility', $visibility)
->addOrderedQty()
->setOrder('ordered_qty', 'desc')
->setPageSize(6);
$_bs_productCollection->load();
So, I set up my module, and it's loading (it shows in the admin/system/config/advanced). Folder structure as follows:
etc/modules/Samsmodule.xml
local/Samsmodule
local/Samsmodule/Catalog
local/Samsmodule/Catalog/etc
local/Samsmodule/Catalog/etc/config.xml
local/Samsmodule/Catalog/Model
local/Samsmodule/Catalog/Model/Resource/Eav/Mysql4/Product/Collection.php
local/Samsmodule/Catalog/Helper (not sure if this is needed or not)
My Samsmodule.xml is:
<config>
<modules>
<Samsmodule_Catalog>
<active>true</active>
<codePool>local</codePool>
</Samsmodule_Catalog>
</modules>
</config>
My config.xml is:
<config>
<modules>
<Samsmodule_Catalog>
<version>0.1.0</version>
</Samsmodule_Catalog>
</modules>
<global>
<models>
<catalog_resource_eav_mysql4>
<rewrite>
<product_collection>Samsmodule_Catalog_Model_Resource_Eav_Mysql4_Product_Collection</product_collection>
</rewrite>
</catalog_resource_eav_mysql4>
</models>
</global>
</config>
And my Collection.php is:
<?php
class Samsmodule_Catalog_Model_Resource_Eav_Mysql4_Product_Collection extends Mage_Catalog_Model_Resource_Eav_Mysql4_Product_Collection
{
public function filterbyBestSelling($attribute,$visibility,$_category,$no_of_items)
{
$this->addAttributeToSelect($attribute)->addOrderedQty()->setOrder('ordered_qty', 'desc')->addAttributeToFilter('visibility', $visibility)->addCategoryFilter($_category)->setPageSize($no_of_items);
return $this;
}
}
And then from my template.phtml I call it like so:
$_bs_productCollection = Mage::getResourceModel('reports/product_collection')
->filterbyBestSelling('name',$visibility,$_category,6);
But it's not working - what am I missing? If I just add the code from my Collection.php to the bottom of my core Collection.php file, and use the same call, it works fine.
(Didn't mean to leave you hanging in the other thread, but there's not a quick answer to this one that wouldn't either seem like magic or just confuse people further.)
You don't need to override a class unless you're going to change the behavior of an existing method. You just need to create a new class that extend the existing class. Here's how you do that.
Terminology For the Normal State of Things
Models are the logical classes/objects that define the behavior of some "thing" (product, etc.) in Magento
Models contain Model Resources. Model Resources are the classes that do the actual fetching of data from some datastore (mysql, etc). This is the Data Mapper pattern.
Collections are objects with array like properties that query the database and return a group of Models. Somewhat confusingly, Collections are also Model Resources.
So, in the normal state of things, you might say something like
Mage::getModel('catalog/product')
to get a product model and the underlying system uses
Mage::getResourceModel('catalog/product');
to get the Mode Resource object that queries for a single product, and either of the following are used
Mage::getResourceModel('catalog/product_collection');
Mage::getModel('catalog/product')->getCollection();
to get the Collection object that queries for many models. In current versions of Magento each Model object has a method named "getCollection" which returns its corresponding Collection Resource.
Reports Off the Rails
Reports go a little sideways, but everything is still within the same universe as described above. It turns out there's no such model as a
Mage::getModel('reports/product');
But there is a collection
Mage::getResourceModel('reports/product_collection')
If you look at the class (which you'll be extending below), you'll see that the 'reports/product_collection' collection
class Mage_Reports_Model_Mysql4_Product_Collection extends Mage_Catalog_Model_Resource_Eav_Mysql4_Product_Collection
extends the the base product collection class. In other words, the client programmer working on the reports section had the exact same though you did. "I want to add some methods to to Mage::getModelResource('catalog/product_collection'). They did this by extending the base class.
Shut Up, I Just Want this to Work
So, what you really want to do here is
Create a new class Samsnamespace_Samscatalog_Model_Mysql4_Product_Collection that extends the base Mage_Reports_Model_Mysql4_Product_Collection collection class.
Ensure that a call to Mage::getModelResource('samscatalog/product_collection') returns an instance of the above class by configurig our module to use Models and Model Resources.
We're also going to change you Module structure around a little bit to help ease naming confusion. I'm not a big fan of giving module folders the same names as core modules (i.e. "Catalog"), and the top level folder (after local/) is actually a Namespace, not a module folder. (A namespace may contain many modules)
We are not overriding the class. We are configuring a custom module under your namespace to use both Models and Model Resources. We're then defining a model resource that extends an existing PHP class already in the system. Overrides should only be used when you want to change the behavior of a particular method call. (Appologies for harping on this, but there's enough general confusion in the communiy about this that it's worth harping on over. and over. and over.)
First, we're going to create the module directory structure and files. We'll just need two
local/Samsnamespace/Samscatalog/etc/config.xml
local/Samsnamespace/Samscatalog/Model/Mysql4/Product/Collection.php
(and don't forget to enable the module in app/etc/modules. If you're not sure what that means, start reading)
The Collection.php file should contain
<?php
class Samsnamespace_Samscatalog_Model_Mysql4_Product_Collection extends Mage_Reports_Model_Mysql4_Product_Collection
{
/* your custom methods go here*/
}
And the config file should contain
<config>
<modules>
<Samsnamespace_Samscatalog>
<version>0.1.0</version>
</Samsnamespace_Samscatalog>
</modules>
<global>
<models>
<samscatalog>
<class>Samsnamespace_Samscatalog_Model</class>
<resourceModel>samscatalog_mysql4</resourceModel>
</samscatalog>
<samscatalog_mysql4>
<class>Samsnamespace_Samscatalog_Model_Mysql4</class>
</samscatalog_mysql4>
</models>
</global>
</config>
With these files in place and the module enabled, you should be able to call
$test = Mage::getResourceModel('samscatalog/product_collection');
var_dump(get_class($test));
and your collection will be returned, and you can add methods to your heart's content.
What's Going On
This is mind bending, so you can stop reading if you want. It's also a rehash of concepts I've covered elsewhere.
When you say
Mage::getResourceModel('samscatalog/product_collection');
The underlying mage system codes says "ok, so this resource model"
samscatalog/product_collection
is part of the
samscatalog/product
model (not entirely true in this case, but it's what the system thinks).
So, since the resource model samscatalog/product_collection is part of the samscatalog/product model, let's look at the config at
global/models/samscatalog/resourceModel
To get the resource model URI of
samscatalog_mysql4
and then let's use that to look at the config at
global/models/samscatalog_mysql4/class
to get the base classname for all Resource Models that are a part of this Module. This ends up being
Samsnamespace_Samscatalog_Model_Mysql4
Which means the samscatalog/product_collection Resource Model is named
Samsnamespace_Samscatalog_Model_Mysql4_Product_Collection
and then its just Magento's standard auto-load which does a
include('Samsnamespace/Samscatalog/Model/Mysql4/Product/Collection.php');
What is the class of the resulting product collection? Does your override work?
This section seems suspect, I'm surprised if it's actually working:
<global>
<models>
<catalog_resource_eav_mysql4>
<rewrite>
<product_collection>Samsmodule_Catalog_Model_Resource_Eav_Mysql4_Product_Collection</product_collection>
</rewrite>
</catalog_resource_eav_mysql4>
</models>
</global>
Try this instead:
<global>
<models>
<catalog>
<rewrite>
<resource_eav_mysql4_product_collection>Samsmodule_Catalog_Model_Resource_Eav_Mysql4_Product_Collection</resource_eav_mysql4_product_collection>
</rewrite>
</catalog>
</models>
</global>
The tag inside of refers to a module. Catalog is a module, while catalog_resource_eav_mysql4 isn't. The tag inside of specifies a class handle, which is basically everything after Mage_Catalog_Model_ in the classname.
Hope that helps!
Thanks,
Joe
