php - Rewriting Magento Core Product Model using Module -

-

not sure doing wrong here.. trying rewrite magento core catalog product model (app/code/mage/catalog/model/product) using custom module. see code below:

app/code/local/james/catalog/etc/config.xml :

   <?xml version="1.0"?> <config> <modules>    <james_catalog>         <version>1.0.1</version>    </james_catalog> </modules> <global>   <models>    <catalog>      <rewrite>        <product>james_catalog_model_product</product>      </rewrite>     </catalog>   </models> </global> </config>

app/code/local/james/catalog/model/product.php :

<?php require_once('mage/catalog/model/product.php');  class james_catalog_model_product extends mage_catalog_model_product {  public function test() {  return "function called"; }    }

app/etc/modules/james_catalog.xml :

<?xml version="1.0"?> <config> <modules>     <james_catalog>         <active>true</active>         <codepool>local</codepool>     </james_catalog> </modules> </config>

then, accessing function :

$_product = mage::getsingleton('catalog/product');  echo $_product->test();

nothing returned. doesn't have access function. ideas? help.

your module should following ...

configuration file app/code/local/james/testcatalog/etc/config.etc 

<?xml version="1.0"?> <config>   <modules>     <james_testcatalog>       <version>1.0.0</version>     </james_testcatalog>   </modules>   <global>     <models>         <catalog>             <rewrite>                 <product>james_testcatalog_model_catalog_product</product>             </rewrite>         </catalog>     </models>   </global> </config>

and model file path : app/code/local/james/testcatalog/model/catalog/product.php

class james_testcatalog_model_catalog_product extends mage_catalog_model_product {      //your code here ...      public function test() {          return "function called";      } }

now can access test method.

i need hash algorithm produces 64-bit hash code ( long ) fewer collisions string.gethashcode() , fast (no expensive calls cryptographic functions). here's implementation of fnv still shows 3% of collisions after testing 2 million random strings. need number way lower. void main() { const string chars = "abcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyz!#@$%^&*()_+}{\":?><,./;'[]0123456789\\"; const int n = 2000000; var random = new random(); var hashes = new hashset<long>(); int collisions = 0; for(int = 0; < n; i++) { var len = random.next(chars.length); var str = new char[len]; (int j = 0; j < len; j++) { str[j] = chars[random.next(chars.length)]; } var s = new string(str); if(!hashes.add(get64bithash( s ))) collisions++; } console.writeline("collision percentage after " + n + " random strings: " + ((doubl
