  • Can I override a theme function with a .tpl file?

    - by Nick Lowman
    Hi everyone, How would I go around overriding a theme function with a .tpl file? I know how to override a .tpl file with a theme function but not the other way round. I can't seem to find anywhere that tells me so, so maybe it's not possible or not good practise. For example if there was a theme function defined in a module called super_results and registered with the theme registry, like the example below, how would I go around overriding it with super_results.tpl.php. 'super_results' => array( 'arguments' => array('title' => NULL, 'results' => NULL, 'votes' => NULL), ), function modulename_super_results($title, $results,$votes){ output HTML }

  • difference between calling javascript function on body load or directly from script.

    - by Abbas
    i am using a javascript where in i am creating multiple div (say 5) at runtime, using javascript function, all the divs contain some text, which is again set at runtime, now i want to disable all the divs at runtime and have the page numbers in the bottom, so that whenever user clicks on the page number only that div should get visible else other should get disable, i have created a function, which accepts parameter, as page number, i enable the div whose page number is clicked and using a for loop, i disable all the other divs, now here my problem is i have created two functions, 1st (for adding divs and disabling all the divs except 1st) and writing content to it, and other for enabling the div whose page number is clicked, and i have called the Adding div function on body onload; now first time when i run, page everthing goes well, but next time when i click on any of the page number, it just gets enabled and again that AddDiv function, runs and re-enables all the divs.. Please reply why this is happening and how should i resolve my issue... Below is my script, content for the div are coming using Json. <body onload="JsonScript();"> <script language="javascript" type="text/javascript"> function JsonScript() { var existingDiv = document.getElementById("form1"); var newAnchorDiv = document.createElement("div"); newAnchorDiv.id = "anchorDiv"; var list = { "Article": articleList }; for(var i=0; i < list.Article.length; i++) { var newDiv = document.createElement("div"); newDiv.id = "div"+(i+1); newDiv.innerHTML = list.Article[i].toString(); newAnchorDiv.innerHTML += "<a href='' onclick='displayMessage("+(i+1)+")'>"+(i+1)+"</a>&nbsp;"; existingDiv.appendChild(newDiv); existingDiv.appendChild(newAnchorDiv); } for(var j = 2; j < list.Article.length + 1; j ++) { var getDivs = document.getElementById("div"+j); getDivs.style.display = "none"; } } function displayMessage(currentId) { var list = {"Article" : articleList} document.getElementById("div"+currentId).style.display = 'block'; for(var i = 1; i < list.Article.length + 1; i++) { if (i != currentId) { document.getElementById("div"+i).style.display = 'none'; } } } </script> Thanks and Regards

  • Rails: common approach for handling exceptions in restful actions on objects that have been destroye

    - by Greg
    It is very common in Rails for an objects_controller controller to have RESTful edit and destroy actions like so: def edit @object = Object.find(params[:id]) end def destroy @object = Object.find(params[:id]) @object.destroy redirect_to :back end With an associated view that provides edit and destroy links like so: <%= link_to "Edit the Object", edit_object_path(object) %> <%= link_to "Delete", object, :confirm => 'Are you sure?', :method => :delete %> And it is easy to blow this up. If I open two browser windows, A and B, destroy an object with the "Delete" link in browser A and then press the "Edit" link in browser B, the find() in the edit action throws an exception. Obviously there are several ways to deal with this in the edit action: catch the exception and recover gracefully use @object = find(:first, "conditions... etc. and test the @object before going further But seeing as this is such a common pattern, I would love to know how other folks deal with this situation.

  • How to ensure that a Serialized object is completely read over a Socket ?

    - by Amitd
    Hi guys, I am trying to write a socket server and Client that communicate with each other via serialized Objects.eg:To Login, Client sends server a serialized Login object and then the server deserialises the object to read login details. Similarly for other types of request/response. I just wanted to be sure if Socket.receive() can read(untill) large serialized objects completely. I have tried this code but seems to fail when a large object is serialised and sent over the internet.(seems to work fine in LAN situations.) http://stackoverflow.com/questions/2134356/sending-large-serialized-objects-over-sockets-is-failing-only-when-trying-to-grow using(MemoryStream ms = new MemoryStream()) { int bytesRead; while((bytesRead = m_socClient.Receive(buffer)) > 0) { ms.Write(buffer, 0, bytesRead); } // access ms.ToArray() or ms.GetBuffer() as desired, or // set Position to 0 and read } Are there any other ways to ensure that the object gets completely read.

  • Java. Best procedure to de-serialize a Java generic object?

    - by Jake
    What is the best procedure for storing and retrieving, using native Java serialization, generic objects like ArrayList<String>? Edit: To clarify. When I serialize an object of type ArrayList<String> I'd like to de-serialize to the same type of object. However, I know of no way to cast back to this generic object without causing warnings.

  • Browser freezes when try to call a JS function along with submission of a form.

    - by Waseem
    I have form in my view like following 1 <div> 2 <% form_tag facebook_user_path do %> 3 <label>Use my photo and name from facebook?</label><br /> 4 <%= check_box_tag 'use_name_and_photo', 'yes', true %> 5 <img src="<%= @user.pic %>" /><% @user.name %> 6 7 <%= submit_tag "Finish", :id => "use_name_and_photo_submit" %> 8 <% end %> 9 </div> I have attached some JS handlers using Jquery to this form. 1 var fb = { 2 extendedPermissions: function () { 3 $("#use_name_and_photo_submit").click(function (event) { 4 FB.Connect.showPermissionDialog("email,read_stream,publish_stream", function (perms) { 5 if (!perms) { 6 alert("You have to grant facebook extended permissions to further browse the application."); 7 } else { 8 $("form").submit(function () { 9 $.post($(this).attr("action"), $(this).serialize(), null, "script"); 10 }); 11 } 12 }); 13 event.preventDefault(); 14 return false; 15 }); 16 } 17 }; 18 19 $(document).ready(function () { 20 fb.extendedPermissions(); 21 }); What I want is that when the user clicks on the "Finish" button, he is prompted for the facebook permissions dialogue and when he gives the permissions, the form is submitted to FacebookUsersController. Right now when I click the "Finish" button, facebook permissions dialogue is initiated but before I am prompted for the actual permission submission window, the browser freezes. Just like I have pressed Esc during the process. In fact status bar of the browser says "Stopped". Any help is highly appreciated.

  • How to pass an associative array as argument to a function in Bash?

    - by niksfirefly
    How do you pass an associative array as an argument to a function? Is this possible in Bash? The code below is not working as expected: function iterateArray { local ADATA="${@}" # associative array for key in "${!ADATA[@]}" do echo "key - ${key}" echo "value: ${ADATA[$key]}" done } Passing associative arrays to a function like normal arrays does not work: iterateArray "$A_DATA" or iterateArray "$A_DATA[@]"

  • How can I create and call a javascript function on a dynamically loaded user control?

    - by Ratan
    when i try to call a javascript function in a dynamically loaded user control, it cannot find the function specified. I have a user control for organizationDetails.ascx. In there, I am using modal popup extender to get some information from the user and then i verify the address through google and suggests the proper format. I am trying to use a java script for a function called for onBlur of a textbox but the mozilla firebug says that the function is not defined, which is not the case. It would be great if someone can help me out here.

  • How do I display java.lang.* object allocations in Eclipse profiler?

    - by Martin Wickman
    I am profiling an application using the Eclipse profiler. I am particularly interested in number of allocated object instances of classes from java.lang (for instance java.lang.String or java.util.HashMap). I also want to know stuff like number of calls to String.equals() etc. I use the "Object Allocations" tab and I shows all classes in my application and a count. It also shows all int[], byte[], long[] etc, but there is no mention of any standard java classes. For instance, this silly code: public static void main(String[] args) { Object obj[] = new Object[1000]; for (int i = 0; i < 1000; i++) { obj[i] = new StringBuffer("foo" + i); } System.out.println (obj[30]); } Shows up in the Object Allocations tab as 7 byte[]s, 4 char[]s and 2 int[]s. It doesn't matter if I use 1000 or 1 iterations. It seems the profiler simply ignores everything that is in any of the java.* packages. The same applies to Execution Statistics as well. Any idea how to display instances of java.* in the Eclipse Profiler?

  • WPF DataGrid Entity Framework: Is it possible to bind a datagrid column to a method/function?

    - by seddler
    Hi. I'm wondering if it's possible to bind a gridcolumn (field) to a method or function of an entity? For example I have two entities Person and Company that both inherit the abstract entity Addressee. In my grid I'm listing all Addressees (both persons and companies). I have a column, Name, in the datagrid that I whish to bind to a function GetName(). This function is part of the entity Addressee and based on what type of addressee it is it returns CompanyName (if company) or FirstName+' '+LastName (if person). I also have tried to add a partial class Addressee with a property Name that does the same thing as the function descried over, but this failes when I'm saving to database because the column Name does not exist in database. Can anybody please help me? :-)

  • Is there any Prototype Javascript function similar to Jquery Live to trace dynamic dom elements?

    - by Wbdvlpr
    Hi Event.observe(window,"load",function() { $$(".elem_classs").findAll(function(node){ return node.getAttribute('title'); }).each(function(node){ new Tooltip(node,node.title); node.removeAttribute("title"); }); }); Using above method, I can retrieve all elements having ".elem_class" and apply some javascript functions on them. But I have a modal/popup box which has some elements also having ".elem_class" and these dont get in the scope of findAll/each as they are loaded into the dom thru ajax. How do I apply the same to dynamically loaded elements as well? I am using Prototype Library. (I have used JQuery's Live function which keeps track of all future elements, but need to achieve something similar using Prototype) Thanks.

  • Is there an equivalent for the Zip function in Clojure Core or Contrib?

    - by John Kane
    In Clojure, I want to combine two lists to give a list of pairs, > (zip '(1 2 3) '(4 5 6)) ((1 4) (2 5) (3 6)) In Haskell or Ruby the function is called zip. Implementing it is not difficult, but I wanted to make sure I wasn't missing a function in Core or Contrib. There is a zip namespace in Core, but it is described as providing access to the Zipper functional technique, which does not appear to be what I am after. Is there an equivalent function for combining 2 or more lists, in this way, in Core? If there is not, is it because there is an idiomatic approach that renders the function unneeded?

  • emacs lisp mapcar doesn't apply function to all elements?

    - by Stephen
    Hi, I have a function that takes a list and replaces some elements. I have constructed it as a closure so that the free variable cannot be modified outside of the function. (defun transform (elems) (lexical-let ( (elems elems) ) (lambda (seq) (let (e) (while (setq e (car elems)) (setf (nth e seq) e) (setq elems (cdr elems))) seq)))) I call this on a list of lists. (defun tester (seq-list) (let ( (elems '(1 3 5)) ) (mapcar (transform elems) seq-list))) => ((10 1 8 3 6 5 4 3 2 1) ("a" "b" "c" "d" "e" "f")) It does not seem to apply the function to the second element of the list provided to tester(). However, if I explicitly apply this function to the individual elements, it works... (defun tester (seq-list) (let ( (elems '(1 3 5)) ) (list (funcall (transform elems) (car seq-list)) (funcall (transform elems) (cadr seq-list))))) => ((10 1 8 3 6 5 4 3 2 1) ("a" 1 "c" 3 "e" 5)) If I write a simple function using the same concepts as above, mapcar seems to work... What could I be doing wrong? (defun transform (x) (lexical-let ( (x x) ) (lambda (y) (+ x y)))) (defun tester (seq) (let ( (x 1) ) (mapcar (transform x) seq))) (tester (list 1 3)) => (2 4) Thanks

  • How to create a GUI inside a function in Matlab?

    - by Paperflyer
    Is there a possibility to write a GUI from inside a function? The Problem is: The callback of all GUI-functions work in the global workspace. But functions have their own workspace and can not access variables in the global workspace. Is there a possibility to make the GUI-functions use the workspace of the function? function myvar = myfunc() myvar = true; h_fig = figure; % create a useless button uicontrol( h_fig, 'style', 'pushbutton', ... 'string', 'clickme', ... 'callback', 'myvar = false' ); % wait for the button to be pressed while myvar pause( 0.2 ); end close( h_fig ); disp( 'this will never be displayed' ); end This event-loop will run indefinitely, since the callback will not modify myvar in the function. Instead it will create a new myvar in the global workspace.

  • ASP.NET MVC2 - specific fields in form pass via a specific object?

    - by ile
    In database I have Contacts table: ContactID (int) FirstName (varchar) LastName (varchar) ... XmlFields (xml) // This field is xml type To create a new contact, I created two classes - one for regular fields and other to display fields from XmlFields field. In Controller, I have following: public ActionResult Create(Contact contact, FormCollection collection) ... Regular field I catch with contact object and those that need to be stored as xml in XmlFields I try to catch with collection object. Problem is that collection object catches all fields, so I wonder if it is possible to isolate xml fields when posting to a specific object so that I can easily manipulate with them. I need this in separated objects because these xml fields are going to be generated dynamically and will be different for every user. Thanks in advance, Ile

  • Why does jQuery do this in its constructor function implementation?

    - by mattcodes
    If we look at the latest jQuery source at http://code.jquery.com/jquery-latest.js we see the following: var jQuery = function( selector, context ) { // The jQuery object is actually just the init constructor 'enhanced' return new jQuery.fn.init( selector, context ); } My understanding of the new keyword in Javascript is essentially JavaScript passes the function an empty object {} and the function sets stuff on it via this.blah. Also from my understanding new differs from .call/.apply etc.. in that the return object also has the prototype set to that of the function. So the return value should have a prototype that the same as jQuery.prototype.init.prototype (or jQuery.fn.init.prototype). However from what I see its prototype is set to jQuery.prototype thus all the commands available to work on the set. Why is this? What am I missing in my understanding?

  • Can you make a PHP function recursive without repeating it's name?

    - by alex
    It's always bugged me a recursive function needs to name itself, when a instantiated class can use $this and a static method can use self etc. Is there a similar way to do this in a recursive function without naming it again (just to cut down on maintenance)? Obviously I could use call_user_func or the __FUNCTION__ constant but I would prefer something less ugly. Update Thanks for your answers. I might stick to including the function name for simple functions, and make take the other approaches for anything more complicated.

  • Applying a function with multiple inputs using Map? (Haskell)

    - by Schroedinger
    G'day guys, Trying currently to finish up a bit of homework I'm working on, and having an issue where I'm trying to apply map across a function that accepts multiple inputs. so in the case I'm using processList f (x:xs) = map accelerateList f xs x xs processList is given a floating value (f) and a List that it sorts into another List Accelerate List takes a floating value (f) a List and a List Object through which it returns another List Object I know my Accelerate List code is correct, but I cannot for the life of me get the syntax for this code working: processList :: Float -> [Object] -> [Object] accelerate f [] = [] accelerate f [x] = [(accelerateForce f x x)] accelerate f (x:xs) = map accelerateList f xs x xs Any ideas? I've been scratching my head for about 3 hours now. I know it's something really simple.

  • Problems with passing an anonymous temporary function-object to a templatized constructor.

    - by Akanksh
    I am trying to attach a function-object to be called on destruction of a templatized class. However, I can not seem to be able to pass the function-object as a temporary. The warning I get is (if the comment the line xi.data = 5;): warning C4930: 'X<T> xi2(writer (__cdecl *)(void))': prototyped function not called (was a variable definition intended?) with [ T=int ] and if I try to use the constructed object, I get a compilation error saying: error C2228: left of '.data' must have class/struct/union I apologize for the lengthy piece of code, but I think all the components need to be visible to assess the situation. template<typename T> struct Base { virtual void run( T& ){} virtual ~Base(){} }; template<typename T, typename D> struct Derived : public Base<T> { virtual void run( T& t ) { D d; d(t); } }; template<typename T> struct X { template<typename R> X(const R& r) { std::cout << "X(R)" << std::endl; ptr = new Derived<T,R>(); } X():ptr(0) { std::cout << "X()" << std::endl; } ~X() { if(ptr) { ptr->run(data); delete ptr; } else { std::cout << "no ptr" << std::endl; } } Base<T>* ptr; T data; }; struct writer { template<typename T> void operator()( const T& i ) { std::cout << "T : " << i << std::endl; } }; int main() { { writer w; X<int> xi2(w); //X<int> xi2(writer()); //This does not work! xi2.data = 15; } return 0; }; The reason I am trying this out is so that I can "somehow" attach function-objects types with the objects without keeping an instance of the function-object itself within the class. Thus when I create an object of class X, I do not have to keep an object of class writer within it, but only a pointer to Base<T> (I'm not sure if I need the <T> here, but for now its there). The problem is that I seem to have to create an object of writer and then pass it to the constructor of X rather than call it like X<int> xi(writer(); I might be missing something completely stupid and obvious here, any suggestions?

  • Can I do this?? Trying to load an object from within itself.

    - by Smikey
    Hi all! I have an object which conforms to the NSCoding protocol. The object contains a method to save itself to memory, like so: - (void)saveToFile { NSMutableData *data = [[NSMutableData alloc] init]; NSKeyedArchiver *archiver = [[NSKeyedArchiver alloc] initForWritingWithMutableData:data]; [archiver encodeObject:self forKey:kDataKey]; [archiver finishEncoding]; [data writeToFile:[self dataFilePath] atomically:YES]; [archiver release]; [data release]; } This works just fine. But I would also like to initialise an empty version of this object and then call its own 'Load' method to load whatever data exists on file into its variables. So I've created the following: - (void)loadFromFile { NSString *filePath = [self dataFilePath]; if ([[NSFileManager defaultManager] fileExistsAtPath:filePath]) { NSData *data = [[NSMutableData alloc] initWithContentsOfFile:[self dataFilePath]]; NSKeyedUnarchiver *unarchiver = [[NSKeyedUnarchiver alloc] initForReadingWithData:data]; self = [unarchiver decodeObjectForKey:kDataKey]; [unarchiver finishDecoding]; } } Now this second method doesn't manage to load any variables. Is this line not possible perhaps? self = [unarchiver decodeObjectForKey:kDataKey]; Ultimately I would like to use the code like this: One viewController takes user entered input, creates an object and saves it to memory using [anObject saveToFile]; And a second viewController creates an empty object, then initialises its values to those stored on file by calling: [emptyObject loadFromFile]; Any suggestions on how to make this work would be hugely appreciated. Thanks :) Michael
