  • How do I set up a route in rails?

    - by NotDan
    In my routes.rb I have this: map.namespace :admin do |admin| admin.resources :galleries do |galleries| galleries.resources :gallery_images, :as=>'images' end end rake routes shows the route created like this: admin_gallery GET /admin/galleries/:id and when I go to this url in my browser: http://192.168.2.2:3000/admin/galleries/11/ I get this error: Unknown action No action responded to 11 But I would have expected it to use the show action/view, what am I doing wrong?

  • Prolog Beginner: How to unify with arithmentic comparison operators or how to get a set var to range

    - by sixtyfootersdude
    I am new to prolog. I need to write an integer adder that will add numbers between 0-9 to other numbers 0-9 and produce a solution 0-18. This is what I want to do: % sudo code add(in1, in2, out) :- in1 < 10, in2 < 10, out < 18. I would like to be able to call it like this: To Check if it is a valid addition: ?- add(1,2,3). true ?- add(1,2,4). false With one missing variable: ?- add(X,2,3). 1 ?- add(1,4,X). 5 With multiple missing variables: ?-add(X,Y,Z). % Some output that would make sense. Some examples could be: X=1, Y=1, Z=2 ; X=2, Y=1, Z=3 ...... I realize that this is probably a pretty simplistic question and it is probably very straightforward. However cording to the prolog tutorial I am using: "Unlike unification Arithmetic Comparison Operators operators cannot be used to give values to a variable. The can only be evaluated when every term on each side have been instantiated."

  • How to zoom IFRAME content only without using a frame set?

    - by Baskaran
    I need to zoom frame content only. Here in my web page I used zoom: 0.75; height: 520px; width: 800px;. If I increase the zoom value it means that the frame size will be increased. <HTML> <HEAD> <TITLE> New Document </TITLE> <STYLE> #frame { width: 800px; height: 520px; border: 1px solid black; } #frame { zoom: 0.75; -moz-transform: scale(0.75); -moz-transform-origin: 0 0; } </STYLE> </HEAD> <BODY> <IFRAME id="frame" src="http://www.google.com"></IFRAME> </BODY> </HTML> In the above sample HTML page I want to zoom the content of the IFRAME without changing the size of that IFRAME.

  • How to properly set button phase after dragging over button?

    - by irobeth
    I have a class (mxml) that extends Button while implementing drag/drop support. When I drag one of them onto another, the drag receiver stays stuck in its 'over' phase until I click on it (As if something about DragManager.acceptDragDrop is preventing the MouseEvent from getting to button) Is there a way to make a button re-evaluate its phase after the drop? I've tried fabricating a MouseEvent and sending it to rollOverHandler with no luck. This resembles the scenario in Button.as (lines 2606-2647) described like Drag over and up mouse down while out of Button roll over Button - stay in "up" phase mouse up while over Button - "over" phase continue with step 2 of first three sequences above This is my drag/drop handler private function dragDropHandler(event:DragEvent):void { trace("dropped"); var ib : IconButton = (event.dragInitiator as IconButton); if(this.data is Section) { if(ib.data is Item) { trace("ITEM"); //move an item into a section. var ae : AldonaEvent = new AldonaEvent(AldonaEvent.MOVE); ae.data = ib.data; dispatchEvent(ae); } else if(ib.data is Section) { trace("SECTION"); //change a section's parent. var ae : AldonaEvent = new AldonaEvent(AldonaEvent.MOVE); ae.data = ib.data; dispatchEvent(ae); } } //you can only drag stuff into sections. }

  • How to set offset in GORM when using createCriteria?

    - by firnnauriel
    I'm just wondering if it's possible for 'createCriteria' to specify the paginateParams (i.e. offset) similar to dynamic finder (findAll, etc.) Note that this code is not working since 'offset' is not documented in http://www.grails.org/doc/1.2.1/ref/Domain%20Classes/createCriteria.html def c = SnbrItemActDistance.createCriteria() def results = c.list { eq('iid', newsId) ge('distance', cap) maxResults(count) offset(offset) order('distance', 'desc') }

  • How do I set the dataProvider for an <s:List> component to be an XML file?

    - by Matt Calthrop
    I've got the latest Beta of Adobe Flash Builder 4. I want to use a <s:List> component, and specify the dataProvider as being an XML file. However, after loads of research (including looking at doc links off labs.adobe.com), I still can't figure out how to do it. The XML file will look something like this: <?xml version="1.0" encoding="ISO-8859-1"?> <imageList> <image location="path/to/file1.jpg" /> <image location="path/to/file2.jpg" /> <image location="path/to/file3.jpg" /> </imageList>

  • Can I configure a strongly typed data set to use nullable values?

    - by Dan Tao
    If I have a strongly typed data table with a column for values of type Int32, and this column allows nulls, then I'll get an exception if I do this for a row where the value is null: int value = row.CustomValue; Instead I need to do this: if (!row.IsCustomValueNull()) { int value = row.CustomValue; // do something with this value } Ideally I would like to be able to do this: int? value = row.CustomValue; Of course I could always write my own method, something like GetCustomValueOrNull; but it'd be preferable if the property auto-generated for the column itself simply returned a nullable. Is this possible?

  • How can I set the Jbuttons in a preferred order?

    - by Umzz Mo
    I have a grid of 30 buttons, and I want to have it from left to right then goes down, right to left, down again left to right. Basically the numbering would be as follow: 1 2 3 4 5 6 7 8 9 10 20 19 18 17 16 15 14 13 12 11 21 22 23 24 25 26 27 28 29 30 So if I have a piece on the button 10 and I instruct it to move up 2 bits it would land on 12 not 19. Below is my Code: //Creates the button using the loop, adds it into the panel and frame. JPanel panel = new JPanel(); panel.setLayout(new GridLayout(3,10)); JButton [] buttons = new JButton[30]; for(int i=0;i<30;i++){ buttons[i] = new JButton("label" + i); buttons[i].setBackground(Color.white); //Puts the player 1 piece on button 1,3,5,7,9 and player 2 piece on button 2,4,6,8,10 if (i < 10) { if (i%2 == 0) { buttons[i].setIcon(piece1); } else { buttons[i].setIcon(piece2); } } panel.add(buttons[i]); } frame.add(panel, BorderLayout.CENTER);

  • Tfs 2010: how to set up a corporate source server?

    - by bwerks
    Hi all, I'm looking for guidance in setting up a corporate source server, but when I google this topic the best I can come up with is articles and walkthrough concerned with configuring VS to use microsoft's public symbol servers for use with debugging .NET assemblies. Provided for background info, the environment I'm concerned with using is Vs2010/Tfs2010. Basically, the workflow I'm looking to facilitate is this: 1) customer reports problem with application 2) application of the appropriate version is installed on a virtual machine 3) developer repros bug attaching to process on virtual machine and leveraging source server (symbol server?) on corporate domain. This is the step I'm concerned with. 4) developer pinpoints problem fixes bug in workspace. 5) developer performs a dll swap on VM to test changes? (side topic, not sure on this) 6) normal development/source control workflows. Any advice is welcome! Edit: since writing this, I have stumbled on this article, which is a nice writeup on the configuration of source server for TFS 2008. Has anyone adapted this for Tfs 2010?

  • How do I set up Scala plugin for NetBeans to copy the Scala runtime library?

    - by Alexey Romanov
    Versions: NetBeans 6.8, Scala Kit 0.16.1 When I compile my project, I get the following output: init: deps-jar: Compiling 2 source files to F:\MyProgramming\NorvigSpellChecker\build\classes compile: Created dir: F:\MyProgramming\NorvigSpellChecker\dist Building jar: F:\MyProgramming\NorvigSpellChecker\dist\NorvigSpellChecker.jar Not copying the libraries. To run this application from the command line without Ant, try: java -jar "F:\MyProgramming\NorvigSpellChecker\dist\NorvigSpellChecker.jar" jar: BUILD SUCCESSFUL (total time: 3 seconds) Of course, the libraries should be copied, so I can't actually run it by using this command line. I don't see any options to copy the library in the project configuration. The plugin uses Ant for building, but I don't have any experience with it; presumably it should be easy enough to tell Ant to copy the libraries. Here is build-impl.xml, what should I do in build.xml?

  • How do I set up a test duplicate of a Django and Postgresql based web application?

    - by cojadate
    Not sure if this is an excessively broad and newbie-ish question for Stack Overflow but here goes: I paid someone else to build a web application for me and now I want to tweak certain aspects of it myself. I learn best by trial and error – changing stuff and seeing what happens. Obviously that's not a great way to treat a live site, so I need to duplicate the site on some kind of test server which I can play with without fear of the consequences. Unfortunately the closest I've come to programming has been creating ActionScript-based websites. I've never touched a database. So I really don't know where to start with setting up a test server. I would really appreciate any advice about where to start. I am completely ignorant and lost here. The web application is built in python/django using a Postgresql database. I use Mac OS X 10.6 if that makes any difference.

  • How can I rotate an image using Java/Swing and then set its origin to 0,0?

    - by JT
    I'm able to rotate an image that has been added to a JLabel. The only problem is that if the height and width are not equal, the rotated image will no longer appear at the JLabel's origin (0,0). Here's what I'm doing. I've also tried using AffineTransform and rotating the image itself, but with the same results. Graphics2D g2d = (Graphics2D)g; g2d.rotate(Math.toRadians(90), image.getWidth()/2, image.getHeight()/2); super.paintComponent(g2d); If I have an image whose width is greater than its height, rotating that image using this method and then painting it will result in the image being painted vertically above the point 0,0, and horizontally to the right of the point 0,0.

  • SQL Server pivots? some way to set column names to values within a row

    - by ccsimpson3
    I am building a system of multiple trackers that are going to use a lot of the same columns so there is a table for the trackers, the tracker columns, then a cross reference for which columns go with which tracker, when a user inserts a tracker row the different column values are stored in multiple rows that share the same record id and store both the value and the name of the particular column. I need to find a way to dynamically change the column name of the value to be the column name that is stored in the same row. i.e. id | value | name ------------------ 23 | red | color 23 | fast | speed needs to look like this. id | color | speed ------------------ 23 | red | fast Any help is greatly appreciated, thank you.

  • How do you set the default source for the Output window in Visual Studio?

    - by Grank
    We added a SharePoint BDC model project to a solution in Visual Studio 2010. Ever since, whenever the solution is built, instead of showing the Build output in the Output window, it insists on having "SharePoint Tools" selected in the "Show Output from:" drop-down, just to say "Model validation started ... Model validation completed with no errors." Short of shutting off any SharePoint projects in the build configuration, can this behavior be overridden?
