  • Can 'locals' be used with 'collection' when rendering partials in Rails?

    - by Gav
    Everything works okay when I try to render a partial like this: = render :partial => "/shared/enquiry/car_type", :collection => @enquiry.available_car_types However, if I also want to pass a variable (in this case 'path', because I'm sharing this partial across two forms), the path is not available to me: = render :partial => "/shared/enquiry/car_type", :collection => @enquiry.available_car_types, :locals => {:path => customers_enquiry_path} I've tried moving things around, but nothing appears to work, leading me to believe one cannot use locals with collections. Any help would be appreciated. Gav

  • Properly removing an Integer from a List<Integer>

    - by Yuval A
    Here's a nice pitfall I just encountered. Consider a list of integers: List<Integer> list = new ArrayList<Integer>(); list.add(5); list.add(6); list.add(7); list.add(1); Any educated guess on what happens when you execute list.remove(1)? What about list.remove(new Integer(1))? This can cause some nasty bugs. What is the proper way to differentiate between remove(int index), which removes an element from given index and remove(Object o), which removes an element by reference, when dealing with lists of integers? The main point to consider here is the one @Nikita mentioned - exact parameter matching takes precedence over auto-boxing.

  • Table and Image in a single page of QTextDocument in Qt4

    - by liaK
    Hi, I want to display a table and a image side by side. i.e Left side the image and right side the table. I want this because the image is the reference image for the data present in the table. I want that output in pdf. So I am using QTextDocument, QTextCursor and QPrinter to get the output in pdf. So how it is possible to display the image and table in QtextDocument i.e within a single page of the pdf? I am using Qt 4.5.3 and Windows Xp. Any pointers regarding this are welcome.

  • declaring a 2D array of pointer objects

    - by Tyler Stennette
    I'm having a tough time figuring out how to instantiate a 2D array of pointer objects. Here is how I'm doing it: Pieces* chessBoard[9][9]; When I want to set it to an actual object pointer, I'm doing the following: chessBoard[1][1] = new Rook(p1Rook); Rook is a class that inherits attributes from the Pieces class and p1Rook is a char variable set to 'R'. This class also implements virtual functions (not pure virtual) from Pieces such as move() or getPiece() that are unique to the particular chess piece. However, when I compile my program, I get the following error: ChessBoard.cpp:69: error: expected type-specifier before ‘Rook’ ChessBoard.cpp:69: error: cannot convert ‘int*’ to ‘Pieces*’ in assignment Can someone please explain what I should change to get rid of this rather annoying persistent error? I would appreciate it.

  • How to determine what invokes User Access Control restrictions?

    - by MX4399
    In a Delphi app intended to build an internet software update service for my software, the Windows 7 UAC system requests authorization from the user to run the exe.The following possible contentious/risk areas exist in the code: A named pipe server is created for communications TCP is used for FTP and HTTP SHGetSpecialFolderPath api call is used Before these items where added UAC did not activate, removing each in turn including all unit reference and then ending with the bare bones exe still causes the UAC event - so its not possible say what is causing it. On top of this Delphi 2007 now requires being launced as an administrator to launcg a debugging process for the app. Question 1 : How can I see what is causing this besides starting from scratch in a new exe - IOW is there a log somewhere I can check Question 2 : Will using a signed exe using authenticode still cause the UAC alert to show

  • Software version numbering with GIT

    - by revocoder revocorp
    Short Want to set automatic (or at least semi-auto) software version numbering in GIT Detailed I'm newby to GIT. Recently created some bare git repo and made some commits and pushes into it. Want to set some starting version number (like v1.0) to my project. I know, there is tag for this reason. Googled it and found bunch of materials. For example: git - the simple guide blog says: You can create a new tag named 1.0.0 by executing git tag 1.0.0 1b2e1d63ff the 1b2e1d63ff stands for the first 10 characters of the commit id you want to reference with your tag. Kudelabs says: $ git tag -a 'milestone1' -m 'starting work for milestone 1, due in 2 weeks' $ git push --tags I'm really confused. What is difference between first and second method: git tag and git tag-a. Can't figure out which to use for this purpose. How can I set version number in bare remote repo, to which I made 5-6 commits and pushes?

  • Using C# Type as generic

    - by I Clark
    I'm trying to create a generic list from a specific Type that is retrieved from elsewhere: Type listType; // Passed in to function, could be anything var list = _service.GetAll<listType>(); However I get a build error of: The type or namespace name 'listType' could not be found (are you missing a using directive or an assembly reference?) Is this even possible or am I setting foot onto C# 4 Dynamic territory? As a background: I want to automatically load all lists with data from the repository. The code below get's passed a Form Model whose properties are iterated for any IEnum (where T inherits from DomainEntity). I want to fill the list with objects of the Type the list made of from the repository. public void LoadLists(object model) { foreach (var property in model.GetType() .GetProperties(BindingFlags.Public | BindingFlags.Instance | BindingFlags.SetProperty)) { if (IsEnumerableOfNssEntities(property.PropertyType)) { var listType = property.PropertyType.GetGenericArguments()[0]; var list = _repository.Query<listType>().ToList(); property.SetValue(model, list, null); } } }

  • Most efficient approach for multilingual PHP website

    - by alexteg
    I am working on a large multilingual website and I am considering different approaches for making it multilingual. The possible alternatives I can think of are: The Gettext functions with generation of .po files One MySQL table with the translations and a unique string ID for each text PHP-files with arrays containing the different translations with unique string IDs As far as I have understood the Gettext functions should be most efficient, but my requirement is that it should be possible to change a text string in the original reference language (English) without the other translations of that string automatically reverting back to English just because a couple of words changed. Is this possible with Gettext? What is the least resource demanding solution? Is using the Gettext functions or PHP files with arrays more or less equally resource demanding? Any other suggestions for more efficient solutions?

  • How do I route watir through a proxy pragmatically?

    - by feydr
    I'm trying to route watir through a proxy pragmatically -- this means within the script I'd like to change my proxy dynamically before launching the browser. Here's what I've tried so far (and so far am failing): I'm running chrome and lucid lynx ubuntu. I chose TREX cause I thought watir might be making use of PROXY or something. I rewrote /usr/bin/google-chrome as: #!/bin/bash /opt/google/chrome/chrome --proxy-server="$TREX" $@ The reason I'm passing in the environment variable to proxy-server rather than http_proxy is because I never could get http_proxy to work as is anyways then I did a simple: require 'rubygems' require 'watir-webdriver' ENV['TREX'] = "XX.XX.XX.XX:YY" browser = Watir::Browser.new(:chrome) browser.goto("http://mysite.com") Anyways, what is happening here is that it is forwarding me to the login page of the proxy rather than just forwarding the request. What am I missing here? I feel like I'm pretty close.

  • PHP: Filling in the 'gaps' in an array

    - by aboved
    Hey gurus, I've got a php array (obtained through checkbox values in a form - as you know checkboxes only show up in the _POST variable when they are not set). Array ( [2] => 0,2 [3] => 0,3 ) I need a way to 'fill in' the gaps between the range 0-5. So above would look like (filling the empty spaces with '-1'. I tried array_merge() with an array filled with '-1' but that didn't work. Array ( [0] => -1 [2] => 0,2 [3] => 0,3 [4] => -1 [5] => -1 ) I think I may have gone down the wrong road with the problem I am trying to solve, but I have put too much time into this solution to back out - a feeling I am sure most of you are familiar with(!) Cheers!

  • Should we use require_once instead header location?

    - by jartaud
    Hello commnunity, i have somthing like this: (if this page needs the user to be logged) if(!isset($_SESSION['usr_id'])){ //if not a logged user $_SESSION['redir']=curPageURL();//Saving the current page for the redirection header('Location: ../Session/loginFrm.php'); } and in loginFrm.php, we do: {...after validation} if(isset($_SESSION['redir'])){ header('Location: '.$_SESSION['redir']); }else{...} in this page, they say we should use something like this instead: ... require_once '../Session/loginFrm.php'; exit(); This doesn't work for me, the session variable now contains the included page, and not the current page. What do you think about?

  • IntPtr arithmetics

    - by Luca
    I tried to allocate an array of structs in this way: struct T { int a; int b; } data = Marshal.AllocHGlobal(count*Marshal.SizeOf(typeof(T)); ... I'd like to access to allocated data "binding" a struct to each element in array allocated with AllocHGlobal... something like this T v; v = (T)Marshal.PtrToStructure(data+1, typeof(T)); but i don't find any convenient way... why IntPtr lack of arithmetics? How can I workaround this is a "safe" way? Someone could confirm that PtrToStructure function copy data into the struct variable? In other words, modifing the struct reflect modifications in the structure array data, or not? Definitely, I want to operate on data pointed by an IntPtr using struct, without copying data each time, avoiding unsafe code. Thank all!

  • Twitter Trends API weekly.json causing error "Cannot use object of type stdClass as array"

  • Need help using ThemeRoller

    - by Music Magi
    Hi - I'm using DataTables to dress up a table I'm using to display XML results based on an XSL transformation. I have everything working from a technical sense (paging, sorting, filtering), but I'm trying to figure out to use a ThemeRoller theme to make it look like they have on their website. So far, I have added the following file to my project with its reference: <link type="text/css" href="css/custom-theme/jquery-ui-1.8.7.custom.css" rel="stylesheet"/> and enabled ThemeRoller themes using the following as per the DataTables website: $(document).ready(function() { $('#mainTable').dataTable( { "bJQueryUI": true, "sPaginationType": "two_button" }); }); The table gets styled, but it doesn't look right with the header rows being too wide and things being on multiple lines that should be on one line. Any indication as to what I'm doing wrong? Thanks very much in advance.

  • How to replace the nth column/field in a comma-separated string using sed/awk?

    - by Peter Meier
    assume I have a string "1,2,3,4" Now I want to replace, e.g. the 3rd field of the string by some different value. "1,2,NEW,4" I managed to do this with the following command: echo "1,2,3,4" | awk -F, -v OFS=, '{$3="NEW"; print }' Now the index for the column to be replaced should be passed as a variable. So in this case index=3 How can I pass this to awk? Because this won't work: echo "1,2,3,4" | awk -F, -v OFS=, '{$index="NEW"; print }' echo "1,2,3,4" | awk -F, -v OFS=, '{$($index)="NEW"; print }' echo "1,2,3,4" | awk -F, -v OFS=, '{\$$index="NEW"; print }' Thanks for your help!

  • Property in a Windows Forms form class only accessable after Load event

    - by Spooky2010
    I'm instantiating and calling Form B from Form A. FormB has some custom properties, to allow me to pass it things like sqlAdaptors and dataset instances. When i instantiate and show Form B from Form A as a dialog form with a Using statement, it all works fine, but i find the properties i pass are not available in Form B until after the form_load event has fired. I was under the impression the properties when passed to a instantiated class should be available from a constructor, but this is not the case. If it try to access the properties before the form load event i get a null reference exception. Is this correct behavior ?

  • jQuery: How to fire event when all asynchronous calls return?

    - by Jeremy
    I have a jQuery application that loads data from five asynchronous server calls. I do not want to display any data until all five calls return. (I plan on displaying a Loading message until that happens.) How can I detect when all five calls have returned? I considered having each callback method increment a variable (using jQuery's data() method, perhaps) and then waiting for the value to become 5. (I am not sure yet how I would listen for that event.) I do not think this is a very good solution, however. What would happen if two calls return at the same time? Is there a better way to do this?

  • Is there a better way than #if DebugMode for logging

    - by Daniel
    I'm making a c++ library thats going to be P/Invoked from c#, so i am unable to breakpoint/debug the c++ side of things. So i decided to add logging so i can see if anything goes wrong and where it happens. I add a #define DebugMode 1 in order to determine if i am to log or not. First of all i'm not very good at c++ but i know enough to get around. So my questions are: Is there a better way than wrapping #if DebugMode #endifs around every Log call? I could simply do that inside the method and just return if logging isn't disabled but won't that mean then all those logging strings will be in the assembly? How can i emulate what printf does with its "..." operator enabling me to pass something like Log("Variable x is {0}", x); Thanks!

  • Why does MySQL autoincrement increase on failed inserts?

    - by Sorcy
    A co-worker just made me aware of a very strange MySQL behavior. Assuming you have a table with an auto_increment field and another field that is set to unique (e.g. a username-field). When trying to insert a row with a username thats already in the table the insert fails, as expected. Yet the auto_increment value is increased as can be seen when you insert a valid new entry after several failed attempts. For example, when our last entry looks like this... ID: 10 Username: myname ...and we try five new entries with the same username value on our next insert we will have created a new row like so: ID: 16 Username: mynewname While this is not a big problem in itself it seems like a very silly attack vector to kill a table by flooding it with failed insert requests, as the MySQL Reference Manual states: "The behavior of the auto-increment mechanism is not defined if [...] the value becomes bigger than the maximum integer that can be stored in the specified integer type." Is this expected behavior?

  • Clone LINQ To SQL object Extension Method throws object dispose exception....

    - by gtas
    Hello all, I have this extension method for cloning my LINQ To SQL objects: public static T CloneObjectGraph<T>(this T obj) where T : class { var serializer = new DataContractSerializer(typeof(T), null, int.MaxValue, false, true, null); using (var ms = new System.IO.MemoryStream()) { serializer.WriteObject(ms, obj); ms.Position = 0; return (T)serializer.ReadObject(ms); } } But while i carry objects with not all references loaded, while qyuerying with DataLoadOptions, sometimes it throws the object disposed exception, but thing is I don't ask for references that is not loaded (null). e.g. I have Customer with many references and i just need to carry on memory the Address reference EntityRef< and i don't Load anything else. But while i clone the object this exception forces me to load all the EntitySet< references with the Customer object, which might be too much and slow down the application speed. Any suggestions?

  • Are there any reasons to make all fields and variables final?

    - by Roman
    In my current project I noticed that all class fields and variable inside methods are declared with final modifier whenever it's possible. Just like here: private final XMLStreamWriter _xmlStreamWriter; private final Marshaller _marshaller; private final OutputStream _documentStream; private final OutputStream _stylesStream; private final XMLStreamWriter _stylesStreamWriter; private final StyleMerger _styleMerger; public DocumentWriter(PhysicalPackage physicalPackage) throws IOException { final Package pkg = new Package(physicalPackage); final Part wordDocumentPart = pkg.createPart( "/word/document.xml", "application/vnd.openxmlformats-officedocument.wordprocessingml.document.main+xml", "http://schemas.openxmlformats.org/officeDocument/2006/relationships/officeDocument"); // styles.xml final Pair<Part, String> wordStylesPart = wordDocumentPart.createRelatedPart(...); ... } Are there any reasons to do so? p.s. As I know project is not supposed to be multithreaded (at least I've heard nothing about it).
