I'm building an application using Durandal 2. I want to define multiple routes using the same VM/View for different context.
Exemple :
/sectionA/:id/home using module ID /viewmodels/home
/sectionB/:id/home using module ID /viewmodels/home too
At first, sectionA and sectionB are meant to use the exact same VM and Views. But, eventually, they will be different. This is not where the issue is since when they'll be different, they'll have their very own VM and shared views (using MVC partials) which will work straight out the box.
The point is, for as long as the page are the same, we don't want to duplicate the VM and Views, generating a lot of garbage for nothing.
I tried the example shown above but that doesn't seems to be possible to do this. Whether the routes are different, it seems that the router cannot make the difference between the two routes and just throw a "route not found" exception although the route is defined in our route definition file.
So the question, is it possible to define two route, with obviously different routes definitions, but using the same moduleId?
If more details are require, don't hesitate to ask for clarifications.
Thanks! :)

How can I manipulate other modules without editing them ? very the same thing that wordpress modules do .
They add functionality to core system without changing the core code and they work together like a charm.
I always wanted to know how to implement this in my own modular application
A long time ago I wrote the blog post "Use 3rd party modules in Zend Framework 2" specifically about extending Zend Framework 2 modules. The answer from Bez is technically correct, it could be a bit more specific about the framework.
Read the full post at https://juriansluiman.nl/article/117/use-3rd-party-modules-in-zend-framework-2, but it gives you a clue about:
Changing a route from a module (say, you want to have the url /account/login instead of /user/login)
Overriding a view script, so you can completely modify the page's rendering
Changing a form object, so you could add new form fields or mark some required field as not required anymore.
This is a long topic, but here is a short gist.
Extensibility in Zend Framework 2 heavily relies on the premise that components can be interchanged, added, and/or substituted.
Read up on SOLID principles: http://en.wikipedia.org/wiki/SOLID_(object-oriented_design)
Modules typically consists of objects working together as a well-oiled machinery, designed to accomplish one thing or a bunch of related things, whatever that may be. These objects are called services, and managed by the service locator/service manager.
A big part of making your module truly extensible is to expect your developers to extend a class or implement a certain interface, which the developer register as services. You should provide a mode of definition wherein the developers can specify which things he wants to substitute, and/or add their own services to -- and this is where the application configuration comes in.
Given the application configuration, you should construct your machinery a.k.a. module services according to options the developer has specified i.e., use the developer defined Foo\Bar\UserService service as the YourModule\UserServiceInterface within your module, etc. (This is usually delegated to service factories, which has the opportunity to read the application configuration, and constructs the appropriate object given a particular set of configuration values.)
EDIT:
To add, a lot can be accomplished by leveraging Zend's Zend\EventManager component. This allows you to give developers the freedom to hook and listen to certain operations of your module and act accordingly (See: http://en.wikipedia.org/wiki/Observer_pattern)
I own a Play 2.1 application.
Initially, I used the default template mechanisms from Play 2.1 until I .. learned AngularJS.
Now, I clearly want my client side to be an AngularJS app.
However, while surfing the net, I find there are no clear way to achieve it:
Letting Play behave as a simple RESTful application (deleting the view folder) and making a totally distinct project to build the view (AngularJS app initialized by grunt.js).
Advantage: Likely to be less messy, and front and backend teams would work easily separately.
Drawback: Need another HTTP server for the AngularJS app.
Try to totally integrate AngularJS app with the traditional Play's workflow.
Drawback: With a pretty complex framework like AngularJS, it would lead to a confusion of templates managementfor instance : scala.html (for Play) / tpl.html (for Angular) ... => messy.
Making a custom folder within the play project but distinct from the initial folders created by the Play scaffolding. Let's call it myangularview instead of traditional view for instance. Then, publish static contents generated by grunt.js into the Play's public folder, in order to be reachable from browser through Play's routing.
Advantage: SRP between components is still fairly respected and no need to use another light HTTP server for the client-side like in 1.
I pointed out my own views of advantage and drawbacks.
What would be a great way to achieve the combination of Play with Angular?
Yes, I'm answering to my own question :)
I came across this way of doing:
http://jeff.konowit.ch/posts/yeoman-rails-angular/
Rails?? No matter the framework is, the need remains exactly same.
It advocates a real separation between APIs (backend side), and front-end side (in this case making AJAX calls to backend server).
Thus, what I've learned is:
During development phase, a developer would use two servers: localhost on two distinct ports.
During production phase, the front-end elements would be encompassed into the whole backend side (the article would deal with a kind public folder, aiming to serve static contents: HTML, angular templates (for instance), CSS etc... Advantage? => dealing with a one and unique serving server's APIs exposition as well as static assets for the UI.
With this organization, some tools like Yeoman would be able to bring some really awesome handy things to developers like for instance: the livereload feature. :):)
Of course, during development phase, we end up with two different domains, (localhost:3000 and localhost:9000 for instance) causing issues for traditional ajax requests. Then, as the article points out, a proxy may be really useful.
I really find this whole practice very elegant and pleasant to work with.
There was an interesting discussion on the play mailinglist a couple of days ago about frontend-stack/solution, could be something in it for you, quite some people using angular it seems: https://groups.google.com/forum/#!searchin/play-framework/frontend/play-framework/IKdOowvRH0s/tQsD9zp--5oJ
I'm trying to switch to ZF2 from ZF1. From what I've read about the new Zend\MVC\Router and the way it is configured, it looks like every single location should be described in ['router']['routes'] config key.
Is that really so? In ZF1 you could build a complex app with multiple locations and not have a single route described. I find it hard to believe, hopefully I am missing something.
Thanks!
The routing works in a similar way to ZF1. The config in the skeleton app includes a few example routes, one of which is a /:controller/:action route (line 42). So this is your out-of-the-box ZF1 style MVC route.
In ZF1, the framework adds a /:controller/:action and /:module/:controller/:action route for you (which you had to remove if you had some custom requirements). In ZF2 you have to define the routes yourself, but if you want the same setup as ZF1, the skeleton app setup works in the same way, just without the module prefix.
I am starting from the Maven chat example and would like to extend it so that multiple independent chats can happen at different URL paths. For now I would be satisfied mapping multiple pages to the index.
My best guess is to put something like Lift RewriteResponse not finding a valid url in the boot strap class. But so far nothing I have tried works.
I am a bit frustrated by the lack of well explained examples on how to do path mapping for different common use cases (same goes for most lift documentation).
Please see http://simply.liftweb.net/index-3.2.html#toc-Subsection-3.2.7
This section describes how to use parameterized URLs.

I'm in the middle of converting an existing app built on top of zend framework to work as a plugin within wordpress as opposed to the standalone application it currently is.
I've never really used zend so I've had to learn about it in order to know where to begin. I must say that at first I didn't think much of zend, but it's funny because the more I understand how it works the more I keep questioning why I'd want to remove dependency when it's a clearly well thought out framework. Then I'm reminded that it's because of wordpress.
Now I already know there are WP plugins to make zend play nice with WP. In fact I'm aleady using a zend framework plugin just to get the app functional within the WP admin area which is allowing me to review code, modify code, refresh the browser, review changes, debug code, again and again.
Anyway, I really don't have a specific question but instead I'm looking for advice from any zend masters out there to offer advice on how to best go about a task like this one.... so any comments, advice, examples or suggestions would be super.
One area I'm a little stuck on is converting parts of zend->db calls to work as wpdb calls instead... specifically the zend->db->select.... not sure what to do with that one.
Also on how to handle all the URL routing with automatic calls to "whatverAction" within thier respective controllers files.
Any help would be great! Thanks
You're probably facing an uphill battle trying to get some of the more major components of ZF to work in harmony with Wordpress. It sounds like you've got a full MVC app that you're trying to integrate into a second app that has very different architecture.
You probably want to think about which components handle which responsibilities. Wordpress has it's own routing and controller system that revolves around posts, pages and 'The Loop'. This is entirely different from Zend's Action Controllers and routing system.
It's possible you could write a WP hook to evaluate every incoming request and decide if it should be handled by WP or a ZF controller. However, it is doubtful you would be able to replace WP's routing system outright with ZF's or vice versa.
Same idea, where Zend_Db is concerned. There's nothing stopping you from using Zend_Db to access Wordpress's database, but trying to somehow convert or adapt Zend_db calls into wpdb calls sounds painful. If you have a large model layer, you probably want to hang on to it, and find a way to translate data from those models into the posts/pages conventions that Wordpress uses.
Personally, I would use ZF to build a robust business layer that can be queried through an object model via a Wordpress plugin, and then rely on Wordpress to do the routing and handle the views.
Zend_DB_Select is simple SQL query (but created using objects) that can be used like any other query. Just turn it into string. Ex.:
mysql_query((string)$zendDbSelectObject);
