  • Time.new does not work as I would expect

    - by Marius Pop
    I am trying to generate some seed material. seed_array.each do |seed| Task.create(date: Date.new(2012,06,seed[1]), start_t: Time.new(2012,6,2,seed[2],seed[3]), end_t: Time.new(2012,6,2,seed[2] + 2,seed[3]), title: "#{seed[0]}") end Ultimately I will put random hours, minutes, seconds. The problem that I am facing is that instead of creating a time with the 2012-06-02 date it creates a time with a different date: 2000-01-01. I tested Time.new(2012,6,2,2,20,45) in rails console and it works as expected. When I am trying to seed my database however some voodo magic happens and I don't get the date I want. Any inputs are appreciated. Thank you! Update1: * [1m[36m (0.0ms)[0m [1mbegin transaction[0m [1m[35mSQL (0.5ms)[0m INSERT INTO "tasks" ("created_at", "date", "description", "end_t", "group_id", "start_t", "title", "updated_at") VALUES (?, ?, ?, ?, ?, ?, ?, ?)

  • Not getting concept of null

    - by appu
    Hy Guys, Beginning with mysql. I am not able to grasp the concept of NULL. Check screen-shot (*declare_not_null, link*). In it when I specifically declared 'name' field to be NOT NULL. When i run the 'desc test' table command, the table description shows default value for name field to be NULL.Why is that so? From what I have read about NULL, it connotes a missing or information that is not applicable. So when I declare a field to be NOT NULL it implies (as per my understanding) that user must enter a value for the name field else the DB engine should generate an error i.e. record will not be entered in DB. However when i run 'insert into test value();' the DB engine enters the record in table. Check screen-shot(*empty_value, link*). FLICKR LINKS *declare_not_null* http://www.flickr.com/photos/55097319@N03/5302758813/ *empty_values* Check the second screenshot on flickr Q.2 what would be sql statemetn to drop a primary key from a table's field. If I use 'ALTER TABLE test drop key id;' it gives the following: ERROR: Incorrect table definition; there can be only one auto column and it must be defined as a key. Thanks for your help..

  • Show my website's content on other websites. Is iframe only option?

    - by Jashwant
    In my project, I have created a code snippet which can be copied and then put in any website. It shows my content on other websites. What I am using now is : <script type='text/javascript'> var user = 'abc'; var age = '23'; document.write('<iframe src="http://www.mysite.com/page.php?user='+ user + '&age=' + age + '" ></iframe'); </script> In page.php, I do some processing based on user and age and show dynamic content. My approach works fine. But when I look into some good standard ways to do such tasks, I find a different way. Take an example of google adsense code. <script type='text/javascript'> var a = 'somedata'; var b = 'someotherdata'; </script> <script type='text/javascript' src='http://www.google.com/adsenseurl.js'></script> I guess, since a and b are global; adsenseurl.js must be using it and may be finally they are showing it on iframe. So, now the question. What's the advantage in using google's approach and whats wrong in my approach ? p.s. I know I should try to avoid using iframes but I dont see any other way to accomplish this.

  • How do I unbind another jQuery function on .click()?

    - by Mike Barwick
    I have this script that run to fix my menu bar to the browser on scroll. Nothing really needs to change here (works as it should). However, you may need it... var div = $('#wizMenuWrap'); var editor = $('#main_wrapper'); var start = $(div).offset().top; $(function fixedPackage(){ $.event.add(window, "scroll", function() { var p = $(window).scrollTop(); $(div).css('position',((p)>start) ? 'fixed' : 'static'); $(div).css('top',((p)>start) ? '0px' : ''); //Adds TOP margin to #main_wrapper (required) $(editor).css('position',((p)>start) ? 'relative' : 'static'); $(editor).css('top',((p)>start) ? '88px' : ''); }); }); Now for the issue at hand. I have another script function that calls a modal pop-up (which again works as it should). However, it's not slick from a UI perspective when I scroll the page when the modals open. So I want to disable the script above when the modal script below is called. In other words, when I click to open the modal pop-up, the script above shouldn't work. $(function () { var setUp = $('.setupButton'); // SHOWS SPECIFIED VIEW $(setUp).click(function () { $('#setupPanel').modal('show'); //PREVENTS PACKAGE SELECT FIXED POSITION ON SCROLL $(setUp).unbind('click',fixedPackage); }); }) As you can see above, I tried to unbind the scroll function (the first code snippet), but this is not correct. These two scripts are in two separate js libraries.

  • Is re-throwing an exception legal in a nested 'try'?

    - by Alexander Gessler
    Is the following well-defined in C++, or not? I am forced to 'convert' exceptions to return codes (the API in question is used by many C users, so I need to make sure all C++ exceptions are caught & handled before control is returned to the caller). enum ErrorCode {…}; ErrorCode dispatcher() { try { throw; } catch (std::bad_alloc&) { return ErrorCode_OutOfMemory; } catch (std::logic_error&) { return ErrorCode_LogicError; } catch (myownstdexcderivedclass&) { return ErrorCode_42; } catch(...) { return ErrorCode_UnknownWeWillAllDie; } } ErrorCode apifunc() { try { // foo() might throw anything foo(); } catch(...) { // dispatcher rethrows the exception and does fine-grained handling return dispatcher(); } return ErrorCode_Fine; } ErrorCode apifunc2() { try { // bar() might throw anything bar(); } catch(...) { return dispatcher(); } return ErrorCode_Fine; } I hope the sample shows my intention. My guess is that this is undefined behaviour, but I'm not sure. Please provide quotes from the standard, if applicable. Alternative approaches are appreciated as well. Thanks!

  • Rails 2.3.4 and jquery form plugin works on development, not in production?

    - by hemajang
    Hello, i'm trying to build a contact form in Rails 2.3.4. I'm using the jQuery Form plugin along with this (http://bassistance.de/jquery-plugins/jquery-plugin-validation/) for validations. Everything works in my development environment (mac os x snow leopard), the loading gif appears and on my log the email gets sent and the "request completed" notice shows. But on my production machine the loading gif just keeps going and the form doesn't get sent. I've waited as long as I could, nothing. Here is my code: /public/javascripts/application.js // client-side validation and ajax submit contact form $('#contactForm').validate( { rules: { 'email[name]': { required: true }, 'email[address]': { required: true, email: true }, 'email[subject]': { required: true }, 'email[body]': { required: true } }, messages: { 'email[name]': "Please enter your name.", 'email[address]': "Please enter a valid email address.", 'email[subject]': "Please enter a subject.", 'email[body]': "Please enter a message." }, submitHandler: function(form) { $(form).ajaxSubmit({ dataType: 'script', beforeSend: function() { $(".loadMsg").show(); } }); return false; } }); I'm using the submitHandler to send the actual ajaxSubmit. I added the "dataType: "script" and the "beforeSubmit" for the loading graphic. def send_mail if request.post? respond_to do |wants| ContactMailer.deliver_contact_request(params[:email]) flash[:notice] = "Email was successfully sent." wants.js end end end Everything works fine on development, but not in production. What am I missing or did wrong?

  • BlackBerry Field class extension will not paint.

    - by jlindenbaum
    Using JRE 5.0.0, simulator device is an 8520. On a screen I am using a FlowFieldManager(Manager.VERTICAL_SCROLL) and adding Fields to it to show data. When I do this.flowManager = new FlowFieldManager(Manager.VERTICAL_SCROLL); Field field = new Field() { protected void paint(Graphics graphics) { graphics.drawTest("Test", 0, 0); } protected void layout(int width, int height) { this.setExtend(300, 300); // just testing } } this.flowManager.add(field); The screen renders correctly and 'Test' appears on the screen. If, on the other hand, I try and abstract this into a class called CustomField with the same properties and add it to the flow manager the render will not happen. Debugging shows that the device enters into the Object, into the layout function, but not the paint function. I can't figure out why the paint function is not called when I extend Field. The 4.5 API says that layout and paint are the only functions that I really need to extend. (getPreferredWidth and getPreferredHeight will be used to calculate screen sizes etc.) Thanks in advance.

  • How to add a checkbox for each row in Rails 3.2 index page?

    - by user938363
    We would like to add a checkbox to each row on Rails index page to flag for the row. This checkbox is not part of the object (no checkbox boolean in database). When the index page shows, a user can check the box to trigger an event for the row in following process: #objects/checkbox_index.html.erb <table> <tr> <th>CheckBox</th> <th>Object Name</th> <th>Object ID</th> </tr> <%= @objects.each do |obj| %> <tr> <td><%= checkbox %></td> <td><%= obj.name %></td> <td><%= obj.id %></td> </tr> <% end %> </table> In controller, the process will be like this: @objects.each do |obj| some_event if obj.checked end There are a couple of questions we don't quite understand: 1. How to declare an array checkbox variable on the form and link it to each row of obj? We have been using `attr_accessor` to declare var for a form. 2. How to retrieve each row on checkbox_index form and pass them back to controller? We are using simple_form for new/edit. Can anyone point me towards any good examples of this sort of behavior, or suggest what we should be thinking about? Many Thanks.

  • Using Visual Studio to make non aspx code-behind pages

    - by rizzle
    I want to build my own "code behind" like pages so that i can have HTML in a HTML file and code in cs file but be able to have Intellesense for the tokens in the HTML file. (i know that's what the .NET page class does, but i want to have something much lighter) EG: in the .html file: <%@ Directive classname="HTMLSnippet" %> <html> <body> <div>[%message%] </body> </html> and in a .cs file public class MyClass : HTMLSnippet { public class MyClass () { snippet.message = "message goes here" } } So my question is how do make the HTMLSnippet class so that it's members are automatically created, and specifically show up in Intellesense as i add tokens to the .html file? I know that .net currently does it by creating the designer.cs file and basically builds a class with all the elements from the page as it goes, and that would work fine but how can i get visual studio to generate that before compiling so that it shows up in Intellesense. Thanks! Clarification I'm not using this as a handler yet, i want to use this to have HTML snippets with tokens be usable in code as an object with properties. so almost like a custom control. I think what i have to do is create a VS add-in that waits for me to type tokens into an .html file then it automatically creates a .cs file with members for each token.

  • Databound Label text displays old data upon save. Re-open record and data is correct?

    - by Mike Hestness
    I have a windows forms application. I have a main form and I have a button on this form to set a "Qualified" date/time stamp. I have a Databound label control that I set the value when the user clicks the button. This date/time stamp is working as far as displaying but when you click the save button it either shows blank or the previous date/time. If you then then close the record and re-open it the new date/time value is displayed so the data is getting to the database it's just not persisting in the dataset as new data?? Not sure why the databinding isn't refreshing the value. I have noticed this behavior even if I use a textbox, same thing if I do it programatically. If I manually type in a value it persists?? Here is the code I'm using in the click event of my button: string result = string.Empty; string jobOrderID = UnitOfWork.MasterDSBS.MJOBO[0].JC_IDNO.ToString(); string timeNow = DateTime.Now.ToString(); //Call Web service to make the update RadServices.Service1 rsWeb = new RadServices.Service1(); result = rsWeb.SetQualifiedDate(timeNow, jobOrderID ); //Changed the qualified label text. _btnQualify.Text = "Qualified"; rlQualifiedDate.Text = timeNow;

  • Timed selector never performed

    - by sudo rm -rf
    I've added an observer for my method: [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(closeViewAfterUpdating) name:@"labelUpdatedShouldReturn" object:nil]; Then my relevant methods: -(void)closeViewAfterUpdating; { NSLog(@"Part 1 called"); [self performSelector:@selector(closeViewAfterUpdating2) withObject:nil afterDelay:2.0]; } -(void)closeViewAfterUpdating2; { NSLog(@"Part 2 called"); [self dismissModalViewControllerAnimated:YES]; } The only reason why I've split this method into two parts is so that I can have a delay before the method is fired. The problem is, the second method is never called. My NSLog output shows Part 1 called, but it never fires part 2. Any ideas? EDIT: I'm calling the notification from a background thread, does that make a difference by any chance? Here's how I'm creating my background thread: [NSThread detachNewThreadSelector:@selector(getWeather) toTarget:self withObject:nil]; and in getWeather I have: [[NSNotificationCenter defaultCenter] postNotificationName:@"updateZipLabel" object:textfield.text]; Also, calling: [self performSelector:@selector(closeViewAfterUpdating2) withObject:nil]; does work. EDITx2: I fixed it. Just needed to post the notification in my main thread and it worked just fine.

  • CSS div and image opacity effect

    - by user1704514
    The following code shows the image in the div tag. <div class='item'> <img class='img' src="image1.png" alt="" /> </div> I am using the following css to add effects to the html image code: img{ width:50px; height:50px; opacity:0.4; filter:alpha(opacity=40); } img:hover{ opacity:1.0; filter:alpha(opacity=100); } I am using this to have opacity effects in css. With this code, the opacity effect works well when I hover over the image itself. But how do I make it so that the opacity effect on the image occurs when I hover over the div tag instead. I want to be able to hover over any part of the item div which encapsulated the image, to get the change opacity effect on the image. NB effect on just the image not the entire div. Can this be done in css? If so how?

  • "The breakpoint will not currently be hit" error while debugging a mixed mode application (c# and unmanaged c++)

    - by user1678403
    While debugging a mixed mode application in VS2010, the breakpoint set on a line of code contained in an unmanaged c++ dll source file (called from a managed c# wrapper class) shows the infamous "The breakpoint will not currently be hit. No symbols have been loaded for this document" info message when hovering the mouse over the breakpoint on the line in question. The breakpoint itself is a red circle with a yellow info triangle instead of the usual solid red orb. Of course, the breakpoint isn't hit when the debugger is executed. Most answers I've found for this warning indicate the breakpoint hasn't been set properly, or that the expected dll is not being loaded, or that the associated pdb file is not located in the correct location, etc. etc. This is not the problem. The application does load and execute the referenced dll correctly. I've verified that the correct pdb file, with the same file date as its dll, is located in the executable's working directory along with the target dll itself. The debugger simply doesn't load the symbols for the dll, and the dll doesn't show in the Modules list. None of the solutions I've found online work for this problem. The dll doesn't show in the modules list available from 'Debug-Windows-Modules' menu selection... even though it is, in fact, loaded. Breakpoints set in the wrapper class work correctly. Deleting the bin and obj directories, cleaning and rebuilding the solution also doesn't help.

  • JQM Nested Popups

    - by mcottingham
    I am having a hard time with the new Alpha release of JQM not showing nested popups. For example, I am displaying a popup form that the user is supposed to fill out, if the server side validation fails, I want to display an error popup. I am finding that the error popup is not being shown. I suspect that it is being shown below the original popup. function bindSongWriterInvite() { // Bind the click event of the invite button $("#invite-songwriter").click(function () { $("#songwriter-invite-popup").popup("open"); }); // Bind the invitation click event of the invite modal $("#songwriter-invite-invite").click(function () { if ($('#songwriter-invite').valid()) { $('#songwriter-invite-popup').popup('close'); $.ajax({ type: 'POST', async: true, url: '/songwriter/jsoncreate', data: $('#songwriter-invite').serialize() + "&songName=" + $("#Song_Title").val(), success: function (response) { if (response.state != "success") { alert("Should be showing error dialog"); mobileBindErrorDialog(response.message); } else { mobileBindErrorDialog("Success!"); } }, failure: function () { mobileBindErrorDialog("Failure!"); }, dataType: 'json' }); } }); // Bind the cancel click event of the invite modal $("#songwriter-invite-cancel").click(function () { $("#songwriter-invite-popup").popup("close"); }); } function mobileBindErrorDialog(errorMessage) { // Close all open popups. This is a work around as the JQM Alpha does not // open new popups in front of all other popups. var error = $("<div></div>").append("<p>" + errorMessage + "</p>") .popup(); $(error).popup("open"); } So, you can see that I attempt to show the error dialog regardless of whether the ajax post succeeds or fails. It just never shows up. Anyone have any thoughts? Mike

  • SAS V9.1.3 - Error when combining %INC and CALL EXECUTE

    - by Mark
    Hi, I am getting a resolution error with some SAS v9.1.3 code. Here is some code I want to store in a .txt file (called problem2.txt) and bring into SAS with a %INC %macro email020; %if &email = 1 %then %do; %put THIS RESOLVED AT 1; %end; %else %if &email = 2 %then %do; %put THIS RESOVLED AT 2; %end; %put _user_; %mend email020; %email020; Then this is the main code: filename problem2 'C:\Documents and Settings\Mark\My Documents\problem2.txt'; %macro report1; %let email = 1; %inc problem2; %mend report1; %macro report2 (inc); %let email = 2; %inc problem2; %mend report2; data test; run = 'YES'; run; data _null_; set test; call execute("%report1"); call execute("%report2"); run; The log shows: NOTE: CALL EXECUTE generated line. 1 + %inc problem2; MLOGIC(EMAIL020): Beginning execution.

The condition was: &email = 1 ERROR: The macro EMAIL020 will stop executing. MLOGIC(EMAIL020): Ending execution. So the question is why does CALL EXECUTE generate %inc problem2 rather than %report1, causing SAS to miss the assignment and what can I do about it?

  • Call to a member function ... on a non-object

    - by jayceekay
    i have an object which is instantiated in an initialize file, which is called with every request. the name is right, so why is it telling me that oourls isn't an object and that redirectLoggedIn isn't its method? a var dump on oourls says NULL. but it's instantiated, and the backtrace at the bottom shows that it goes through initialization and instantiates it. pretty small snippet of code, here's the relevant bit: if($email) { global $session; $session->grantLogin($email); global $oourls; $oourls->redirectLoggedIn(); } else { return false; } and here's the output of debug_print_backtrace i threw in above the oourls method call because i'm completely confused: #0 accounts::verifyEmailRegisterAccount(37a6274c8f4bfa5c537b40e8e04d634a) called at [\public\includes\default\verifyemail.php:16] #1 require_once(\public\includes\default\verifyemail.php) called at [\support\php\ObjectOrientedURLs.class.php:48] #2 ObjectOrientedURLs->mhqqrVerifyemail(Array ([0] => 37a6274c8f4bfa5c537b40e8e04d634a)) #3 ReflectionMethod->invoke(ObjectOrientedURLs Object (), Array ([0] => 37a6274c8f4bfa5c537b40e8e04d634a)) called at [\support\php\ObjectOrientedURLs.class.php:280] #4 ObjectOrientedURLs->parseAndInvokeURL() called at [\support\php\ObjectOrientedURLs.class.php:255] #5 ObjectOrientedURLs->__construct() called at [\support\php\initialize.php:76] #6 require_once(\support\php\initialize.php) called at [\public\index.php:2]

  • One controller with multiple models? Am I doing this correctly?

    - by user363243
    My web app, up until this point, has been fairly straight forward. I have Users, Contacts, Appointments and a few other things to manage. All of these are easy - it's just one model per section so I just did a scaffold for each, then modified the scaffolded code to fit my need. Pretty easy... Unfortunately I am having a problem on this next section because I want the 'Financials' section of my app to be more in depth than the other sections which I simply scaffolded. For example, when the user clicks the 'Contacts' link on the navigation bar, it just shows a list of contacts, pretty straight forward and is in line with the scaffold. However, when the user clicks the 'Financials' link on the navigation bar, I want to show the bank accounts on the left of the page and a few of the transactions on the right. So the financials tab will basically work with data from two models: transactions and bank_accounts. I think I should make the models (transactions & bank_accounts) and then make a controller called Financials, then I can query the models from the Financials controller and display the pages in app/views/financials/ Am I correct in this app layout? I have never worked with more than the basics of scaffolding so I want to ensure I get this right! Thank you!

  • jQuery validation plugin: valid() does not work with remote validation ?

    - by a-dilla
    I got started by following this awesome tutorial, but wanted to do the validation on on keyup and place my errors somewhere else. The remote validation shows its own error message at the appropriate times, making me think I had it working. But if I ask specifically if a field with remote validation is valid, it says no, actually, its not. In application.js I have this... $("#new_user").validate({ rules: { "user[login]": {required: true, minlength: 3, remote: "/live_validations/check_login"}, }, messages: { "user[login]": {required: " ", minlength: " ", remote: " "}, } }); $("#user_login").keyup(function(){ if($(this).valid()){ $(this).siblings(".feedback").html("0"); }else{ $(this).siblings(".feedback").html("1"); } }) And then this in the rails app... def check_login @user = User.find_by_login(params[:user][:login]) respond_to do |format| format.json { render :json => @user ? "false" : "true" } end end I think that my problem might have everything to do with this ticket over at jQuery, and tried to implement that code, but, being new to jQuery, it's all a bit over my head. When I say bit, I mean way way. Any ideas to fix it, or a new way to look at it, would be a big help.

  • Eclipc java,writting a program [closed]

    - by ghassar
    I have an important exercise for that i found in the internet please i need help in using eclipc java thanks i have to design, implement, test and document a Java program (a set of classes) for one of the following problem specifications: Problem 1 – Jubilee Estate Agency Property Management System A local Estate Agent would like a prototype system to keep track of properties that are offered for sale. The Estate Agent sells domestic and commercial properties. You will need to define classes that represent the Estate Agency System. You should design your system and the classes that you will need before starting coding. Your system must have a graphical user interface and be designed and developed using the object-oriented principles of the MVC architecture design pattern i.e. the user interface class must be separate from the other classes. The initial basic requirements for the system are as follows: • Include a list of domestic properties for sale that include details of: address, description, selling price, and number of rooms • Include a list of commercial properties for sale that include details of: address, description, selling price, and area in square metres • Enable the properties that are for sale to be viewed on the screen • Allow the customer to select one or more properties to be placed on a ‘viewing list’ so that the properties can be visited in person • Display on the screen the viewing list that shows the details of the properties chosen • Provide a basic search facility to find properties that are for sale in a particular price band and display the results • Enable a property to be marked as sold

  • Java Daemon Threading with JNI

    - by gwin003
    I have a Java applet that creates a new non-daemon thread like so: Thread childThread = new Thread(new MyRunnable(_this)); childThread.setDaemon(false); childThread.start(); Then my MyRunnable object calls a native method that is implemented in C++: @Override public void run() { while (true) { if (!ran) { System.out.println("isDaemon: " + Thread.currentThread().isDaemon()); _applet.invokePrintManager(_applet.fFormType, _applet.fFormName, _applet.fPrintImmediately, _applet.fDataSet); ran = true; } } } This C++ method calls into a C# DLL that shows a form. My problem is, whenever the user navigates away from the page with a Java applet on it, JVM (and my C# form) is killed. I need the form and JVM to remain open until it is closed by the user. I tried setting my thread to be a non-daemon thread, which is working because System.out.println("isDaemon: " + Thread.currentThread().isDaemon() prints isDaemon: false. Is there something related to the way that the C# form is created (is there another thread I'm not accounting for) or something I am overlooking?? My thread is not a daemon thread, but the JVM is being killed anyways.

  • CakePHP "down for maintenance" page

    - by user1852176
    I found this post about how to create a "down for maintenance" page but I'm having some trouble getting it to work properly. define('MAINTENANCE', 1); if(MAINTENANCE > 0){ require('maintenance.php'); die(); } When I place this code in /webroot.index.php it works. However, the answer suggests adding an IP address check so that if it's down, I would still be able to view it and make sure any updates went through smoothly. So, it would look something like this define('MAINTENANCE', 0); if(MAINTENANCE > 0 && $_SERVER['REMOTE_ADDR'] !='188.YOUR.IP.HERE'){ require('maintenance.php'); die(); } The issue is, my IP address will NOT be detected by cake. I've typed echo $_SERVER['REMOTE_ADDR'] and it just shows ::1. I also tried using my user_id but I got the following error Class 'AuthComponent' not found in.... I tried /index.php and /App/index.php but the maintenance page wasn't triggered and the page loads normally.

  • Cannot get list of elements using Linq to XML

    - by Blackator
    Sample XML: <CONFIGURATION> <Files> <File>D:\Test\TestFolder\TestFolder1\TestFile.txt</File> <File>D:\Test\TestFolder\TestFolder1\TestFile01.txt</File> <File>D:\Test\TestFolder\TestFolder1\TestFile02.txt</File> <File>D:\Test\TestFolder\TestFolder1\TestFile03.txt</File> <File>D:\Test\TestFolder\TestFolder1\TestFile04.txt</File> </Files> <SizeMB>3</SizeMB> <BackupLocation>D:\Log backups\File backups</BackupLocation> </CONFIGURATION> I've been doing some tutorials but I am unable to get all the list of file inside the files element. It only shows the first element and doesn't display the rest. This is my code: var fileFolders = from file in XDocument.Load(@"D:\Hello\backupconfig1.xml").Descendants("Files") select new { File = file.Element("File").Value }; foreach (var fileFolder in fileFolders) { Console.WriteLine("File = " + fileFolder.File); } How do I display all the File in the Files element, the SizeMB and BackupLocation? Thanks
