• In Ruby on Rails, routes.rb, if map.something will create something_path and something_url, does map

  - by Jian Lin

  In Ruby on Rails, routes.rb, if we create a "named route" map.something ":a/:b", :controller => 'foobar' it will also create something_path and something_url which are two methods usable in the controller and in the view. Does map.connect create something like that too? Otherwise, isn't map.connect somewhat disadvantaged in this way? I checked that connect_path and connect_url both aren't created automatically.

• Mustache vs other engines. Maybe I should use another template engine?

  - by marcioAlmada

  I'm passing an object to mustache and this object has a method with one parameter. Is something like this possible with Mustache and PHP? {{object.method(parameter)}} If it gets too laborious to achieve this with Mustache, what template engine would you recommend? Remember I need to pass parameters to object methods while in the view context (like we do with helpers). The nearest as possible to mustache syntax is welcome.

• Design pattern for adding / removing elements

  - by de3

  Wikipedia's definition for Iterator pattern design: the Iterator pattern is a design pattern in which iterators are used to access the elements of an aggregate object sequentially without exposing its underlying implementation. Iterator interface in java provides the following methods hasNext() next() remove() Is there a pattern design, or a java interface for inserting / deleting elements, and getting length of the aggregate object, in addition to iterating them? I know remove() is an optional method that can be used once per call to next(), but I am implementing a circular FIFO array and need a method delete() independent of iterator's next().

• Parse string as if it were a querystring in Ruby on Rails

  - by Koning WWWWWWWWWWWWWWWWWWWWWWW

  I have a string like this: "foo=bar&bar=foo&hello=hi" Does Ruby on Rails provide methods to parse this as if it is a querystring, so I get a hash like this: { :foo => "bar", :bar => "foo", :hello => "hi" } Or must I write it myself? EDIT Please note that the string above is not a real querystring from a URL, but rather a string stored in a cookie from Facebook Connect.

• Disposing the members that implement IDisposable.

  - by Amby

  In my Dispose methods (like the one below), everytime i want to call someObj.Dispose() i also have a check for someObj!=null. Is that because of bad design on my part? Is their a cleaner way to ascertain that Dispose of all the members (implementing IDisposable) being used in an object is called without having a risk of NullReference exception ? protected void Dispose(bool disposing) { if (disposing) { if (_splitTradePopupManager != null) { _splitTradePopupManager.Dispose(); } } } Thanks for your interest.

• How can I know whether an instance implements a method in Objective-C ?

  - by Thomas Joulin

  I would like to know if an instance implements a specific method. I could use respondsToSelector: but it returns YES if the instance inherits the method... I could loop through the methods of class_copyMethodList(), but since I might want to check a lot of instances, I wanted to know if there was a simpler solution (like repondsToSelector:, but restricted to the class itself...)

• Creating a "permanent" Cocoa object

  - by quixoto

  I have an object factory that hands out instances of certain "constant" objects. I'd like these objects to be protected against bad memory management by clients. This is how I've overridden the class's key methods. Am I missing anything (code or other considerations)? - (id)retain { return self; } - (NSUInteger)retainCount { return UINT_MAX; } - (void)release { // nothing. }

• How to discover classes with [Authorize] attributes using Reflection in C#? (or How to build Dynamic

  - by Pretzel

  Maybe I should back-up and widen the scope before diving into the title question... I'm currently writing a web app in ASP.NET MVC 1.0 (although I do have MVC 2.0 installed on my PC, so I'm not exactly restricted to 1.0) -- I've started with the standard MVC project which has your basic "Welcome to ASP.NET MVC" and shows both the [Home] tab and [About] tab in the upper-right corner. Pretty standard, right? I've added 4 new Controller classes, let's call them "Astronomer", "Biologist", "Chemist", and "Physicist". Attached to each new controller class is the [Authorize] attribute. For example, for the BiologistController.cs [Authorize(Roles = "Biologist,Admin")] public class BiologistController : Controller { public ActionResult Index() { return View(); } } These [Authorize] tags naturally limit which user can access different controllers depending on Roles, but I want to dynamically build a Menu at the top of my website in the Site.Master Page based on the Roles the user is a part of. So for example, if JoeUser was a member of Roles "Astronomer" and "Physicist", the navigation menu would say: [Home] [Astronomer] [Physicist] [About] And naturally, it would not list links to "Biologist" or "Chemist" controller Index page. Or if "JohnAdmin" was a member of Role "Admin", links to all 4 controllers would show up in the navigation bar. Ok, you prolly get the idea... Starting with the answer from this StackOverflow topic about Dynamic Menu building in ASP.NET, I'm trying to understand how I would fully implement this. (I'm a newbie and need a little more guidance, so please bare with me.) The answer proposes Extending the Controller class (call it "ExtController") and then have each new WhateverController inherit from ExtController. My conclusion is that I would need to use Reflection in this ExtController Constructor to determine which Classes and Methods have [Authorize] attributes attached to them to determine the Roles. Then using a Static Dictionary, store the Roles and Controllers/Methods in key-value pairs. I imagine it something like this: public class ExtController : Controller { protected static Dictionary<Type,List<string>> ControllerRolesDictionary; protected override void OnActionExecuted(ActionExecutedContext filterContext) { // build list of menu items based on user's permissions, and add it to ViewData IEnumerable<MenuItem> menu = BuildMenu(); ViewData["Menu"] = menu; } private IEnumerable<MenuItem> BuildMenu() { // Code to build a menu SomeRoleProvider rp = new SomeRoleProvider(); foreach (var role in rp.GetRolesForUser(HttpContext.User.Identity.Name)) { } } public ExtController() { // Use this.GetType() to determine if this Controller is already in the Dictionary if (!ControllerRolesDictionary.ContainsKey(this.GetType())) { // If not, use Reflection to add List of Roles to Dictionary // associating with Controller } } } Is this doable? If so, how do I perform Reflection in the ExtController constructor to discover the [Authorize] attribute and related Roles (if any) ALSO! Feel free to go out-of-scope on this question and suggest an alternate way of solving this "Dynamic Site.Master Menu based on Roles" problem. I'm the first to admit that this may not be the best approach.

• When you need pass by reference in Java to assign values to multiple parameters, how do you do it?

  - by mr popo

  In order to refactor some methods into smaller ones, I need pass by reference, since I can only have one return type. I could create a different return or parameter type whenever I need to do this, but then I'd end up with a bunch of bloated, seemingly unnecessary classes. What is the best alternative here, besides redesigning the program, which can't be done?

  Hi. I get from another class string that must be converted to char. It usually contains only one char and that's not a problem. But control chars i receive like '\n' or '\t'. Is there standard methods to convert this to endline or tab char or i need to parse it myself?

• Under what circumstances is jQuery's document.ready() not required?

  - by Phil.Wheeler

  While John Resig's recommendation is, quite rightly, to declare all events within a jquery.document.ready() function, I know that you don't actually have to put everything in there. In fact, there are cases where it may be more appropriate to deliberately put methods outside of the ready event. But what are those cases? Obviously best practice dictates that all events are declared within the ready event, so what would best practice be for declarations outside that event?

• reduce bandwidth streaming mp3s php...

  - by Scarface

  Hey guys, quick question for any experts out there. I am allowing users to upload and post mp3s so other users can listen to/stream. I was wondering if anyone had any tips for reducing bandwidth, or any tips or methods for streaming mp3s. I currently just reference the location of the file with my flash mp3 player after the file has been uploaded. I would ask about images as well, but I am pretty sure they can be compressed using gzip or mod_deflate

• How to check which action method rendered the current view (from within the current view) ?

  - by Richard77

  Hello, I would like to know how to check which action displayed the current View (from the current view). For instance, to check if controller myController originated the rendering (I guess) I can write: <% if(ViewContext.Controller is myApplication.Controllers.myController)%> In fact, I want to use the same View model for 2 actions methods, like this: <% If( First Action rendered this view){%> // Display this <%} else {%> //Display that <%}%> Thanks for helping

• Objective-C retain counts in dealloc

  - by Michael Waterfall

  I'm seeing something fairly strange here, I've got breakpoints set in various dealloc methods in my app, and on inspection, the retain counts of the object self varies from 1 to 0. When dealloc is called, will the retain count of the object be set to 0 already? I'm using print (int) [self retainCount] in the console to test this. The 0's seem to only appear in the dealloc of my NSOperation's that are being run in an NSOperationQueue. Any idea why this is?
