  • Trying to manually recreate a simple generate/scaffolding script

    - by montooner
    I'm trying to understand Rails from the ground up. I want to learn how to manually create basic show-all/show-single/CRUD functionality in the framework. I currently am working on the display-all functionality, but am stopped by an error when I try to request all items in the Products db Here are the steps I've taken so far: script/generate controller Products script/generate model Products rake db:migrate modified products_controller.rb to add: def index() { @products = Product.all} (error: uninitialized constant ProductsController::Product) ideally, dump all orders in the view What's the fix?

  • Can I access Spring session-scoped beans from application-scoped beans? How?

    - by Corvus
    I'm trying to make this 2-player web game application using Spring MVC. I have session-scoped beans Player and application-scoped bean GameList, which creates and stores Game instances and passes them to Players. On player creates a game and gets its ID from GameList and other player sends ID to GameList and gets Game instance. The Game instance has its players as attributes. Problem is that each player sees only himself instead of the other one. Example of what each player sees: First player (Alice) creates a game: Creator: Alice, Joiner: Empty Second player (Bob) joins the game: Creator: Bob, Joiner: Bob First player refreshes her browser Creator: Alice, Joiner: Alice What I want them to see is Creator: Alice, Joiner: Bob. Easy way to achieve this is saving information about players instead of references to players, but the game object needs to call methods on its player objects, so this is not a solution. I think it's because of aop:scoped-proxy of session-scoped Player bean. If I understand this, the Game object has reference to proxy, which refers to Player object of current session. Can Game instance save/access the other Player objects somehow? beans in dispatcher-servlet.xml: <bean id="userDao" class="authorization.UserDaoFakeImpl" /> <bean id="gameList" class="model.GameList" /> <bean name="/init/*" class="controller.InitController" > <property name="gameList" ref="gameList" /> <property name="game" ref="game" /> <property name="player" ref="player" /> </bean> <bean id="game" class="model.GameContainer" scope="session"> <aop:scoped-proxy/> </bean> <bean id="player" class="beans.Player" scope="session"> <aop:scoped-proxy/> </bean> methods in controller.InitController private GameList gameList; private GameContainer game; private Player player; public ModelAndView create(HttpServletRequest request, HttpServletResponse response) throws Exception { game.setGame(gameList.create(player)); return new ModelAndView("redirect:game"); } public ModelAndView join(HttpServletRequest request, HttpServletResponse response, GameId gameId) throws Exception { game.setGame(gameList.join(player, gameId.getId())); return new ModelAndView("redirect:game"); } called methods in model.gameList public Game create(Player creator) { Integer code = generateCode(); Game game = new Game(creator, code); games.put(code, game); return game; } public Game join(Player joiner, Integer code) { Game game = games.get(code); if (game!=null) { game.setJoiner(joiner); } return game; }

  • Ubiquitous way to get the file system root of a .NET WEB application

    - by Eddie
    Similar to Ubiquitous way to get the root directory an application is running in via C#, but that question seems to be related to Win Forms. How would the same be done for Web Forms? I was using... HttpContext.Current.Server.MapPath("~") This works great for handling HTTP requests but seems not to work if a scheduler like Quartz.NET invokes a job (the problem I am having). The HttpContext.Current is null in that scenario since an actual HTTP request is not made.

  • Ajax message best practices

    - by hhj
    Say I need to use ajax to asynchronously ask the server for an xml file containing relevant data. What is the best practice on what this message should look like? Should it be a string like get_data or something similar? Should it be xml? I don't really need long polling since its a one-time (or close to it) request. Thanks.

  • Tell jQuery to ignore clicks during an animation sequence

    - by dclowd9901
    I'm in the midst of writing a slideShow app (click a button, and you slide through a list of images) for jQuery, but I've run into a little bug where it will respond to the click() request even while an animation is happening. I'm using the animate() function already, so that isn't staving off the additional animation requests. Any way to program around this?

  • ASP.NET MVC BaseController to dynamically set MasterPage file

    - by rockinthesixstring
    I've built a Base Controller that all of my Controllers inherit from, and I've got it setup so that it checks the browser type and returns the appropriate MasterPageFile on the fly. I'm wondering if this is an efficient way to do this or if I should optimize it another way. Public Class BaseController : Inherits System.Web.Mvc.Controller Protected Overrides Function View(ByVal viewName As String, ByVal masterName As String, ByVal model As Object) As System.Web.Mvc.ViewResult If Request.Browser.IsMobileDevice Then Return MyBase.View(viewName, "Mobile", model) Else Return MyBase.View(viewName, "Site", model) End If End Function End Class

  • Servlet IOException when streaming a Byte Array

    - by MontyBongo
    I occasionally get an IOException from a Servlet I have that writes a byte array to the outputstream in order to provide a file download capability. This download servlet has a reasonable amount of traffic (100k hits a month) and this exception occurs rarely, around 1-2 times a month. I have tried recreating the exception by using the exact same Base64 String and no exception is raised and the Servlet behaves as designed. Is this IO Exception being caused by something outside my applications control? For example a network issue or the user resetting the connection? I have tried to google the cause of an IOException at this point in the stack but to no avail. The environment is running Tomcat 5.5 on CentOS 5.3 with an Apache HTTP Server acting as a proxy using proxy_ajp.

  • ASP.NET ascx.cs via GET

    - by Heavy Bytes
    Say I have this url: http://site.example/dir/ In this folder I have these files: test.ascx.cs and test.ascx Just to be clear, I am not a .NET developer. From a security point of view - why can't I access http://site.example/dir/test.ascx.cs and how secure is it to keep those files there? I assume IIS filters out request that query these kind of files, but can someone explain me this? Thank you.

  • Getting HTTP GET variables using Tipfy

    - by Vestonian
    Hey everyone, I'm currently playing around with tipfy on Google's Appengine and just recently ran into a problem: I can't for the life of me find any documentation on how to use GET variables in my application, I've tried sifting through both tipfy and Werkzeug's documentations with no success. I know that I can use request.form.get('variable') to get POST variables and **kwargs in my handlers for URL variables, but that's as much as the documentation will tell me. Any ideas?

But I was installing a bunch of packages in Ubuntu yesterday, using apt-get and I started wondering if anyone had adapted it or produced anything similar for Windows. What I mean is a) an package manager / installer for Windows. And b) a repository of free-software packages in a compatible format.
