I'm trying to create module for magento. It use my own class
class Myfirm_Extname_Model_Mysql4_Product_Option extends Mage_Catalog_Model_Resource_Product_Option
In magento 1.7 all works fine, in 1.5 - error: Error class Mage_Catalog_Model_Resource_Product_Option not found.
How can I make class that will be inherited from Mage_Catalog_Model_Resource_Product_Option or Mage_Catalog_Model_Resource_Eav_Mysql4_Product_Option depending on the version of magento?
I solved this prodblem.
protected function _getResource() {
if (version_compare(Mage::getVersion(), '1.6.0', '<')) {
$this->_resourceName = $this->_resourceName.'_oldversion';
}
if (empty($this->_resourceName)) {
Mage::throwException(Mage::helper('core')->__('Resource is not set.'));
}
return Mage::getResourceSingleton($this->_resourceName);
}
And then create 2 resource model class for old version of magento and new

I have created a custom mapper class as below but ABP does not automatically register and use it while mapping.
https://docs.abp.io/en/abp/4.4/Object-To-Object-Mapping#iobjectmapper-tsource-tdestination-interface
Sorry for less detail, i have added some below,
I have found that mycustommapperclass's interface different from my object mapper,
should I implement for all container types?
public class HierachyItemCustomMapper : IObjectMapper<HierachyItem, HierachyItemDto>, ITransientDependency
{
and my usage like
var nodeListDto = ObjectMapper.Map<IEnumerable<HierachyItem>, IEnumerable<HierachyItemDto>>(nodeList);
How can i handle this?
Obviously I am looking for a result instead of foreach iterator loop.
Edit:
it have found that it is known issue as below
https://github.com/abpframework/abp/issues/94
I've tried just before and it seems it works as expected.
This is my HierachyItemCustomMapper class which I've created in the Application layer. (It should be created in the Application layer.)
public class HierachyItemCustomMapper : IObjectMapper<HierachyItem, HierachyItemDto>, ITransientDependency
{
public HierachyItemDto Map(HierachyItem source)
{
return new HierachyItemDto
{
Name = source.Name
};
}
public HierachyItemDto Map(HierachyItem source, HierachyItemDto destination)
{
destination.Name = source.Name;
return destination;
}
}
I've just added a property named Name in my both classes (HierachyItem and HierachyItemDto) to test.
You probably didn't define it in the Application layer and that cause the problem. Can you check it?
It's simple , your defination is wrong
it should be like that
public class HierachyItemCustomMapper : IObjectMapper<IEnumerable<HierachyItem>,
IEnumerable<HierachyItemDto>>, ITransientDependency {}
as it searches for exact defination match , and if you want to add also capability of using ObjectMapper.Map<HierachyItem, HierachyItemDto>
you can make your custom mapper defination like that
public class HierachyItemCustomMapper : IObjectMapper<IEnumerable<HierachyItem>,
IEnumerable<HierachyItemDto>>, IObjectMapper<HierachyItem, HierachyItemDto> ,
ITransientDependency {}
and you will implement both
good luck
I have the following code...
class BasePage{
constructor(driver){
...
}
}
class Section extends BasePage{
constructor(driver, parent){
super(driver);
...
}
...
}
export {BasePage, Section}
This seems to work, however, when I try to move section into its own folder and file like this...
import {BasePage} from "../BasePage";
export class Section extends BasePage{
constructor(driver, parent){
super(driver);
}
}
I get an error...
(node:12480) UnhandledPromiseRejectionWarning: ReferenceError: BasePage is not defined
at file ... Section.mjs
This doesn't make any sense to me and if I take the extends off and try to instantiate it works fine...
export class Section{
constructor(driver, parent){
new BasePage(driver); // works fine
}
}
What is going on here? Why am I getting a BasePage not defined?
Update
Here is the whole code
You have a circular dependency.
index.mjs loads BasePage.mjs
BasePage.mjs loads Other.mjs before running export class BasePage {}
Other.mjs loads Section.mjs
Section.mjs skips BasePage.mjs because it already in-progress from step 2.
Section.mjs tries to run export class Section extends BasePage { /* ... */ }, which throws because export class BasePage {} from step 2 hasn't run yet.
You haven't shown why you need to import Other inside BasePage so it is hard to recommend changes, but essentially you'll want to not do that.
I'm using tapestry 5.4.1. I have a component with a module that requires prototype. I know prototype is available in the core stack. However how do I import this as a dependency.
My module:
define(["prototype"], function(container, link) {
return new Ajax.PeriodicalUpdater(container, link, {
method : 'post', frequency : 5, decay : 1
});
});
I tried adding this to the class but the path cannot be resolved
#Import(library = {"prototype.js"})
public class Update {
Tried injecting the asset and adding it to the environmental javascriptsupport but it somehow looks for it in the wrong location.
#Inject
#Path("classpath:META-INF/assets/tapestry5/prototype.js")
private Asset prototype;
and
javascriptSupport.importJavaScriptLibrary(prototype);
javascriptSupport.require("update").with(container, getLink());
I don't want to hard code the url with the generated hash.
/assets/meta/z67bxxxx/tapestry5/scriptaculous_1_9_0/prototype.js
Anything I am missing here? Any help would be appreciated.
Make sure you define correct infrastructure in your AppModule
#ApplicationDefaults
public static void contributeApplicationDefaults(MappedConfiguration<String, Object> configuration) {
configuration.add(SymbolConstants.JAVASCRIPT_INFRASTRUCTURE_PROVIDER, "prototype");
}
You don't have to specify dependency clearly ["prototype"].
I am wondering how would you use typescript IOC specifically node app.
In case of external module-based architecture there is no any classes in the app. Just pure modules because my app heavily depends on node_modules.
How would I integrate IOC solution in such case? Any thoughts?
Here is my specific case I want to use IOC for:
I have mongoose model:
interface IStuffModel extends IStuff, mongoose.Document { }
var Stuff= mongoose.model<IStuffModel>('Stuff', Schemas.stuffSchema);
export = Stuff;
And related fake class:
export class Stuff implements IStuff {
//do stuff
}
How would I integrate IOC solution in such case
Here is a very popular library that I recommend : https://github.com/inversify/InversifyJS
External modules
Using external modules doesn't change the code at all. Instead of
kernel.bind(new TypeBinding<FooBarInterface>("FooBarInterface", FooBar));
Production
You just have
import {ProdFooBar} from "./prodFooBar";
kernel.bind(new TypeBinding<FooBarInterface>("FooBarInterface", ProdFooBar));
Test
import {MockFooBar} from "./mockFooBar";
kernel.bind(new TypeBinding<FooBarInterface>("FooBarInterface", MockFooBar));
As Basarat indicated in his answer, I have developed an IoC container called InversifyJS with advanced dependency injection features like contextual bindings.
You need to follow 3 basic steps to use it:
1. Add annotations
The annotation API is based on Angular 2.0:
import { injectable, inject } from "inversify";
#injectable()
class Katana implements IKatana {
public hit() {
return "cut!";
}
}
#injectable()
class Shuriken implements IShuriken {
public throw() {
return "hit!";
}
}
#injectable()
class Ninja implements INinja {
private _katana: IKatana;
private _shuriken: IShuriken;
public constructor(
#inject("IKatana") katana: IKatana,
#inject("IShuriken") shuriken: IShuriken
) {
this._katana = katana;
this._shuriken = shuriken;
}
public fight() { return this._katana.hit(); };
public sneak() { return this._shuriken.throw(); };
}
2. Declare bindings
The binding API is based on Ninject:
import { Kernel } from "inversify";
import { Ninja } from "./entities/ninja";
import { Katana } from "./entities/katana";
import { Shuriken} from "./entities/shuriken";
var kernel = new Kernel();
kernel.bind<INinja>("INinja").to(Ninja);
kernel.bind<IKatana>("IKatana").to(Katana);
kernel.bind<IShuriken>("IShuriken").to(Shuriken);
export default kernel;
3. Resolve dependencies
The resolution API is based on Ninject:
import kernel = from "./inversify.config";
var ninja = kernel.get<INinja>("INinja");
expect(ninja.fight()).eql("cut!"); // true
expect(ninja.sneak()).eql("hit!"); // true
The latest release (2.0.0) supports many use cases:
Kernel modules
Kernel middleware
Use classes, string literals or Symbols as dependency identifiers
Injection of constant values
Injection of class constructors
Injection of factories
Auto factory
Injection of providers (async factory)
Activation handlers (used to inject proxies)
Multi injections
Tagged bindings
Custom tag decorators
Named bindings
Contextual bindings
Friendly exceptions (e.g. Circular dependencies)
You can learn more about it at https://github.com/inversify/InversifyJS
In the particular context of Node.js there is a hapi.js example that uses InversifyJS.

I need to override the Request class, but there is no instance method.
What do i need to change to get it working in kohana v3.3 ?
Thx in advance!
The use of Request::instance() was replaced with Request::$current since Kohana 3.2, so you should write this in top of your Request class:
class Request extends Kohana_Request {
public static function current( & $uri = TRUE)
{
