  • How can I stop rails validating xml?

    - by Andrei T. Ursan
    I'm submitting to a rails webservice the following message: xmlPostData = "<message> <message-text>" + MESSAGE_WITH_XML + "</message-text> <name>" + subject + "</name> <f1>" + toPhone + "</f1> <f2>" + fromPhone + "</f2> </message>"; The problem is the the field with contain a text with XML data, is a workaround but I need to be able to submit that xml to the db and get it from there. Can I stop rails validating and replacing my xml in json format? this is how it looks: --- !map:HashWithIndifferentAccess smil: !map:HashWithIndifferentAccess head: !map:HashWithIndifferentAccess layout: !map:HashWithIndifferentAccess root_layout: !map:HashWithIndifferentAccess height: &quot;600&quot; background_color: white width: &quot;800&quot; type: text/smil-basic-layout body: !map:HashWithIndifferentAccess par: !map:HashWithIndifferentAccess text: !map:HashWithIndifferentAccess left: &quot;33&quot; begin: &quot;33&quot; dur: &quot;33&quot; val: 34343434343434343aaaaaaa height: &quot;33&quot; width: &quot;33&quot; top: &quot;33&quot; And this is the ruby method from the rails webservice: # POST /messages # POST /messages.xml def create @message = Message.new(params[:message]) respond_to do |format| if @message.save flash[:notice] = 'Message was successfully created.' format.html { redirect_to(@message) } format.xml { render :xml => @message, :status => :created, :location => @message } else format.html { render :action => "new" } format.xml { render :xml => @message.errors, :status => :unprocessable_entity } end end end Is a workaround but for the moment this has to work ...

  • My AJAX is only firing once,

    - by sea_1987
    Hi There, I ahave some ajax that is fired when a checkbox is clicked, it essentially sends a query string to a PHP script and then returns the relevant HTML, however, if I select a select it works fine if I then slect another checkbox as well as the previous I get no activity what so ever, not even any errors in firebug, it is very curious, does anyone have any ideas? //Location AJAX //var dataObject = new Object(); var selected = new Array(); //alert(selected); $('#areas input.radio').change(function(){ // will trigger when the checked status changes var checked = $(this).attr("checked"); // will return "checked" or false I think. // Do whatever request you like with the checked status if(checked == true) { //selected.join('&'); selected = $('input:checked').map(function() { return $(this).attr('name')+"="+$(this).val(); }).get(); getQuery = selected.join('&')+"&location_submit=Next"; alert(getQuery); $.ajax({ type:"POST", url:"/search/location", data: getQuery, success:function(data){ //alert(getQuery); //console.log(data); $('body.secEmp').html(data); } }); } else { //do something to remove the content here alert($(this).attr('name')); } });

  • ASP.Net GridView UpdatePanel Paging Gives Error On Second Click

    - by joe
    I'm trying to implement a GridView with paging inside a UpdatePanel. Everything works great when I do my first click. The paging kicks in and the next set of data is loaded quickly. However, when I then try to click a link for another page of data, I get the following error: Sys.WebForms.PageRequestManagerServerErrorException: An unknown error occurred while processing the request on the server. The status code returned from the server was: 12030 aspx code <asp:UpdatePanel ID="UpdatePanel1" runat="server"> <contenttemplate> <asp:GridView ID="GridView1" runat="server" CellPadding="2" AllowPaging="true" AllowSorting="true" PageSize="20" OnPageIndexChanging="GridView1_PageIndexChanging" OnSorting="GridView1_PageSorting" AutoGenerateColumns="False"> <Columns> <asp:BoundField DataField="ActivityLogID" HeaderText="Activity Log ID" SortExpression="ActivityLogID" /> <asp:BoundField DataField="ActivityDate" HeaderText="Activity Date" SortExpression="ActivityDate" /> <asp:BoundField DataField="ntUserID" HeaderText="NTUserID" SortExpression="ntUserID" /> <asp:BoundField DataField="ActivityStatus" HeaderText="Activity Status" SortExpression="ActivityStatus" /> </Columns> </asp:GridView> </contenttemplate> </asp:UpdatePanel> code behind private void bindGridView(string sortExp, string sortDir) { SqlCommand mySqlCommand = new SqlCommand(sSQL, mySQLconnection); SqlDataAdapter mySqlAdapter = new SqlDataAdapter(mySqlCommand); mySqlAdapter.Fill(dtDataTable); DataView myDataView = new DataView(); myDataView = dt.DefaultView; if (sortExp != string.Empty) { myDataView.Sort = string.Format("{0} {1}", sortExp, sortDir); } GridView1.DataSource = myDataView; GridView1.DataBind(); if (mySQLconnection.State == ConnectionState.Open) { mySQLconnection.Close(); } } protected void GridView1_PageIndexChanging(object sender, GridViewPageEventArgs e) { GridView1.PageIndex = e.NewPageIndex; bindGridView(); } protected void GridView1_PageSorting(object sender, GridViewSortEventArgs e) { bindGridView(e.SortExpression, sortOrder); } any clues on what is causing the error on the second click?

  • Making an AJAX WCF Web Service request during an Async Postback

    - by nekno
    I want to provide status updates during a long-running task on an ASP.NET WebForms page with AJAX. Is there a way to get the ScriptManager to execute and process a script for a web service request during an async postback? I have a script on the page that makes a web service request. It runs on page load and periodically using setInterval(). It's running correctly before the async postback is initiated, but it stops running during the async postback, and doesn't run again until after the async postback completes. I have an UpdatePanel with a button to trigger an async postback, which executes the long-running task. I also have an instance of an AJAX WCF Web service that is working correctly to fetch data and present it on the page but, like I said, it doesn't fetch and present the data until after the async postback completes. During the async postback, the long-running task sends updates from the page to the web service. The problem is that I can debug and step through the web service and see that the status updates are correctly set, but the updates aren't retrieved by the client script until the async postback completes. It seems the Script Manager is busy executing the async postback, so it doesn't run my other JavaScript via setInterval() until the postback completes. Is there a way to get the Script Manager, or otherwise, to run the script to fetch data from the WCF web service during the async postback? I've tried various methods of using the PageRequestManager to run the script on the client-side BeginRequest event for the async postback, but it runs the script, then stops processing the code that should be running via setInterval() while the page request executes.

  • Detect if any USB drive is detected or if not using WinForm Application in Visual C#

    - by Pavan Kumar
    I want to do the following things in my application 1) I want to display whether any USB drive is inserted or not in my application to prompt the user to insert a USB drive. I just want to notify the user if any USB dirve is inserted else prompt him to insert one using a label or something (i want to avoid messagebox as it will keep appearing whenever a device is inserted or removed. It will be irritating for the end user) in my Visual C# WinForm Application. If any USB drive is present display "USB drive detected" in the label. The user may add one or more USB sticks but the status will remain same. When there is none then the status of the label will change to "No USB drives found.Please insert a USB drive". 2) When one or more USB drive is added the volume name with the drive letter for example "James(F:)" is added to the Combobox list. The combobox list also needs to remove the entry for the USB drive added in the list automatically when it is removed . So when there is no USB the list should be empty and the label will again prompt user to insert a USB stick or drive.

  • dojo.io.iframe erroring when uploading a file

    - by Grant Collins
    Hi, Hit an interesting problem today when trying to upload an image file < 2MB using dojo.io.iframe. My function to process the form is called, but before the form is posted to the server I am getting the following error: TypeError: ifd.getElementsByTagName("textarea")[0] is undefined My function that is used to action the post of the form is : function uploadnewlogo(){ var logoDiv = dojo.byId('userlogo'); var logoMsg = dojo.byId('uploadmesg'); //prep the io frame to send logo data. dojo.io.iframe.send({ url: "/users/profile/changelogo/", method: "post", handleAs: "text", form: dojo.byId('logoUploadFrm'), handle: function(data,ioArgs){ var response = dojo.fromJson(data); if(response.status == 'success'){ //first clear the image //dojo.style(logoDiv, "display", "none"); logoDiv.innerHTML = ""; //then we update the image logoDiv.innerHTML = response.image; }else if(response.status == 'error'){ logoMsg.innerHTML = data.mesg; }else{ logoMsg.innerHTML = '<div class="error">Whoops! We can not process your image.</div>'; } }, error: function(data, ioArgs){ logoMsg.innerHTML = '<div class="error">' + data + '</div>'; } }); } The form is very basic with just a File input component and a simple button that calls this bit of javascript and dojo. I've got very similar code in my application that uploads word/pdf documents and that doesn't error, but for some reason this does. Any ideas or pointers on what I should try to get this to work without errors? Oh I'm using php and Zend framework for the backend if that has anything to do with it, but I doubt it as it's not even hitting the server before it fails. Many thanks, Grant

  • How to show errors using JSON when an update fails in Rails 2.3.5 with jQuery

    - by Fortuity
    I've got in-place editing on a page in my app (using Rails 2.3.5 and jQuery). I want to know how to display an error on the page when the update fails. I'm using ajax (an XMLHttpRequest) to save an update to a Comment object. The controller has an update method like this: def update @comment = Comment.find(params[:id]) respond_to do |format| # if @comment.update_attributes!(params[:comment]) if false #deliberately forcing a fail here to see what happens format.json { render :nothing => true } else format.json { render :json => @comment.errors, :status => :unprocessable_entity } end end end In Firebug, I can see the server returns a "422" (an appropriate validation error status code). But it's a response to an XMLHttpRequest so there is no redirect to an error page. I think I actually want to do this: format.json { render :json => @comment.errors} and trigger some Javascript function that iterates through (and displays) any errors. I'm using a rails plugin http://github.com/janv/rest_in_place/ to implement the in-place editing. It doesn't appear to have any callback function to handle a failure. What are my options? Can I write some Javascript to respond to a failure condition without hacking the plugin? Do I have to hack the rest_in_place plugin to handle a failure condition? Is there a better plugin (for Rails or jQuery) that handles in-place editing, including failure conditions?

  • Android SMS API

    - by Schildmeijer
    I know that the SMS content provider is not part of the public API (at least not documented), but if I understand correctly it's still possible to use many of the SMS features as long as you know how to use the API(?). E.g it's pretty straightforward to insert an SMS into your inbox: ContentValues values = new ContentValues(); values.put("address", "+457014921911"); contentResolver.insert(Uri.parse("content://sms"), values); Unfortunately this does not trigger the standard "new-SMS-in-your-inbox" notification. Is it possible to trigger this manually? Edit: AFAIK the "standard mail application (Messaging)" in Android is listening for incoming SMSes using the android.permission.RECEIVE_SMS permission. And then, when a new SMS has arrived, a status bar notification is inserted with a "special" notification id. So one solution to my problem (stated above) could be to find, and send the correct broadcast intent; something like "NEW SMS HAS ARRIVED"-intent. Edit: Downloaded a third party messaging application (chompsms) from Android market. This application satisfies my needs better. When i execute the code above the chompsms notice the new sms and shows the "standard status bar notification". So I would say that the standard Android Messaging application is not detecting sms properly? Or am I wrong?

  • How can I transform XML to invalid XML using XSLT?

    - by Damovisa
    I need to transform a valid XML document to the OFX v1.0.2 format. This format is more or less XML, but it's technically invalid and therefore cannot be parsed as XML. I'm having trouble getting my Xml transformation working because the .Net XslCompiledTransform object insists on interpreting the XSL as an XML document (which is fair enough). If I escape the xml-ish tags using &lt; and &gt, they get removed when I download the file. Here's the start of my XSLT: <xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0"> <xsl:output method="text"></xsl:output> <xsl:param name="currentdate"></xsl:param> <xsl:template match="Transactions"> OFXHEADER:100 DATA:OFXSGML VERSION:102 SECURITY:NONE ENCODING:USASCII CHARSET:1252 COMPRESSION:NONE OLDFILEUID:NONE NEWFILEUID:NONE <OFX> <SIGNONMSGSRSV1> <SONRS> <STATUS> <CODE>0 <SEVERITY>INFO </STATUS> <DTSERVER><xsl:value-of select="$currentdate" /> <LANGUAGE>ENG Any suggestions?

  • Javascript Detect Control Key Held on Mouseup

    - by Michael Mikowski
    I've searched a good deal, and can't seem to find a satisfactory solution. I hope someone can help. While I am using jQuery, I am also writing many thousands of lines of Javascript. So a "pure" javascript solution is just fine. I'm trying to determine if the control key is physically held down on a mouseup event. That's it; there are no other preconditions. Does anyone know how to do this reliably, cross-browser? I've tried storing this in a state variable by noting when the key is pressed and released: // BEGIN store control key status in hash_state $().bind('keydown','ctrl',function( arg_obj_e ){ hash_state.sw_ctrldn = true; console.debug( hash_state.sw_ctrldn ); }); $().bind('keyup','ctrl',function( arg_obj_e ){ hash_state.sw_ctrldn = false; console.debug( hash_state.sw_ctrldn ); }); // END store control key status in hash_state However, this really doesn't work. If you test this using firebug and watch the console, you will see that auto-repeat seems to happen, and the value toggles. I inspected the mouseup event to see if there is anything useful there, but to no avail: var debugEvent = function( arg_obj_e ){ var str = ''; for ( var attr in arg_obj_e ){ str += attr + ': ' + arg_obj_e[attr] + '\n'; } console.debug(str); } Any help would be appreciated.

  • LINQ to SQL - Tracking New / Dirty Objects

    - by Joseph Sturtevant
    Is there a way to determine if a LINQ object has not yet been inserted in the database (new) or has been changed since the last update (dirty)? I plan on binding my UI to LINQ objects (using WPF) and need it to behave differently depending whether or not the object is already in the database. MyDataContext context = new MyDataContext(); MyObject obj; if (new Random().NextDouble() > .5) obj = new MyObject(); else obj = context.MyObjects.First(); // How can I distinguish these two cases? The only simple solution I can think of is to set the primary key of new records to a negative value (my PKs are an identity field and will therefore be set to a positive integer on INSERT). This will only work for detecting new records. It also requires identity PKs, and requires control of the code creating the new object. Is there a better way to do this? It seems like LINQ must be internally tracking the status of these objects so that it can know what to do on context.SubmitChanges(). Is there some way to access that "object status"? Clarification Apparently my initial question was confusing. I'm not looking for a way to insert or update records. I'm looking for a way, given any LINQ object, to determine if that object has not been inserted (new) or has been changed since its last update (dirty).

  • Why Does the iPad Main View Refuse to go FullScreen?

    - by dugla
    I am doing an imaging app for iPad and it requires use of the entire screen. The approach I have used on iPhone does not appear to work on iPad. In Interface Builder I have set the UIToolbar to translucent.This code echos the dimensions of the main view before and after requesting fullscreen. (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { [self.window addSubview:self.viewController.view]; NSLog(@"Hello Popover AD - application did Finish Launching With Options - viewSize: %f %f BEFORE", self.viewController.view.bounds.size.width, self.viewController.view.bounds.size.height); [self.viewController setWantsFullScreenLayout:YES]; [self.viewController.view layoutIfNeeded]; NSLog(@"Hello Popover AD - application did Finish Launching With Options - viewSize: %f %f AFTER", self.viewController.view.bounds.size.width, self.viewController.view.bounds.size.height); [self.window makeKeyAndVisible]; return YES; } This is what NSlog has to say: Hello Popover AD - application did Finish Launching With Options - viewSize: 768 1004 BEFORE Hello Popover AD - application did Finish Launching With Options - viewSize: 768 1004 AFTER Can someone please tell me what I am doing incorrectly here? Note, on iPhone I set fullscreen within the init method of the relevant ViewController. Can view resizing only be done in a ViewController? My ultimate goal is a fullscreen view nicely tucked underneath a translucent status bar and tool bar. I will retract the status/tool bars when user interaction begins in the main view. Thanks, Doug

  • PJSIP Custom Registration Header (iOS)

    - by Daniel Redington
    I am attempting to setup SIP communication with an internal server (using the PJSIP library), however, this server requires a custom header field with a specified header value for the REGISTRATION call. For example's sake we'll call this required header "MyHeader". From what I've found, the pjsua_acc_add() function will add an account and register it to the server using a config struct. The parameter "reg_hdr_list" of the config struct has the description "The optional custom SIP headers to be put in the registration request." Which sounds like exactly what I need, however doesn't seem to have any effect on the call itself. Here's what I have so far: pjsua_acc_config cfg; pjsua_acc_config_default(&cfg); //...Some other config stuff related to the server... pjsip_hdr test; test.name = pj_str("MyHeader"); test.sname = pj_str("MyHdr"); test.type = PJSIP_H_OTHER; test.prev = cfg.reg_hdr_list.prev; test.next = cfg.reg_hdr_list.next; cfg.reg_hdr_list = test; pj_status_t status; status = pjsua_acc_add(&cfg, PJ_TRUE, &acc_id); From the server side, there are no extra header fields or anything. And the struct that is used to define the header (pjsua_hdr) has no "value" or equivalent field, so even if it did create the header, how does it set the value? Here's the refrence for the header list definition: Link And the reference for the header struct: Link Any help would be greatly appreciated!

  • How can I make TextToSpeech to speak a text with max volume and restore original volume after speak end?

    - by HelloCW
    I save the current volume both STREAM_RING and STREAM_MUSIC before sTts.get().speak(s, TextToSpeech.QUEUE_ADD, null), I hope the TextToSpeech can speak a text with max volume, but in fact I find the TextToSpeech speak the text with current volume, it seems that sTts.get().speak is asynchronous. How can I make TextToSpeech to speak a text with max volume and restore original volume after speak end? Thanks! public class SpeechTxt { private static SoftReference<TextToSpeech> sTts; public static void SpeakOut(final Context context, final String s) { final Context appContext = context.getApplicationContext(); if (sTts == null) { sTts = new SoftReference<TextToSpeech>(new TextToSpeech(appContext, new TextToSpeech.OnInitListener() { @Override public void onInit(int status) { if (status == TextToSpeech.SUCCESS) { speak(appContext, s); } else { } } })); } else { speak(appContext, s); } } private static void speak(Context context, String s) { if (sTts != null) { switch (sTts.get().setLanguage(Locale.getDefault())) { case TextToSpeech.LANG_COUNTRY_AVAILABLE: case TextToSpeech.LANG_COUNTRY_VAR_AVAILABLE: case TextToSpeech.LANG_AVAILABLE: { sTts.get().setPitch((float) 0.6); sTts.get().setSpeechRate((float) 0.8); int currentRing=PublicParFun.GetCurrentVol(context, AudioManager.STREAM_RING); int currentPlay=PublicParFun.GetCurrentVol(context, AudioManager.STREAM_MUSIC); PublicParFun.SetRingVol(context, 0); PublicParFun.SetPlayVol(context,1000000); sTts.get().speak(s, TextToSpeech.QUEUE_ADD, null); PublicParFun.SetRingVol(context, currentRing); PublicParFun.SetPlayVol(context,currentPlay); break; } case TextToSpeech.LANG_MISSING_DATA: { break; } case TextToSpeech.LANG_NOT_SUPPORTED: // not much to do here } } } public static int GetCurrentVol(Context myContext,int streamType){ AudioManager mAudioManager = (AudioManager)myContext.getSystemService(Context.AUDIO_SERVICE); int current = mAudioManager.getStreamVolume( streamType); return current; } public static void SetRingVol(Context myContext,int vol){ SetVol(myContext,AudioManager.STREAM_RING, vol); } public static void SetPlayVol(Context myContext,int vol){ SetVol(myContext,AudioManager.STREAM_MUSIC, vol); } private static void SetVol(Context myContext,int streamType,int vol){ AudioManager mAudioManager = (AudioManager)myContext.getSystemService(Context.AUDIO_SERVICE); int max = mAudioManager.getStreamMaxVolume(streamType); if (vol>max){ vol=max; } mAudioManager.setStreamVolume(streamType,vol, 0); } }

  • boost::binding that which is already bound

    - by PaulH
    I have a Visual Studio 2008 C++ application that does something like this: template< typename Fcn > inline void Bar( Fcn fcn ) // line 84 { fcn(); }; template< typename Fcn > inline void Foo( Fcn fcn ) { // this works fine Bar( fcn ); // this fails to compile boost::bind( Bar, fcn )(); }; void main() { SYSTEM_POWER_STATUS_EX status = { 0 }; Foo( boost::bind( ::GetSystemPowerStatusEx, &status, true ) ); // line 160 } *The call to GetSystemPowerStatusEx() is just for demonstration. Insert your favorite call there and the behavior is the same. When I go to compile this, I get 84 errors. I won't post them all unless asked, but they start with this: 1>.\MyApp.cpp(99) : error C2896: 'boost::_bi::bind_t<_bi::dm_result<MT::* ,A1>::type,boost::_mfi::dm<M,T>,_bi::list_av_1<A1>::type> boost::bind(M T::* ,A1)' : cannot use function template 'void Bar(Fcn)' as a function argument 1> .\MyApp.cpp(84) : see declaration of 'Bar' 1> .\MyApp.cpp(160) : see reference to function template instantiation 'void Foo<boost::_bi::bind_t<R,F,L>>(Fcn)' being compiled 1> with 1> [ 1> R=BOOL, 1> F=BOOL (__cdecl *)(PSYSTEM_POWER_STATUS_EX,BOOL), 1> L=boost::_bi::list2<boost::_bi::value<_SYSTEM_POWER_STATUS_EX *>,boost::_bi::value<bool>>, 1> Fcn=boost::_bi::bind_t<BOOL,BOOL (__cdecl *)(PSYSTEM_POWER_STATUS_EX,BOOL),boost::_bi::list2<boost::_bi::value<_SYSTEM_POWER_STATUS_EX *>,boost::_bi::value<bool>>> 1> ] If anybody can point out what I may be doing wrong, I would appreciate it.

  • jQuery ajax success chaining Internet Explorer Issues

    - by Nickd
    I have a jQuery ajax function that retrieves JSON data. In the success block I call another function to parse the data and update the page. At the end of this parsing/updating function a different ajax call is made. This works perfectly in all browsers except Internet Explorer (7 and 8). The problem is Internet explorer thinks the script is taking too long to process because the success block from the first ajax call doesn't complete until the 2nd ajax call finishes. I get the message: "Stop running this script? A script on this page is causing your web browser to run slowly. If it continues to run, your computer might become unresponsive." My jQuery code: $("#id_select").bind("change", function(e){ $.ajax({ url: "/retrieve_data.js", data: {id:$(e.target).children(":selected").attr("value")}, type: "get", dataType:"json", success: function(data, status, form){ processData(data); }, error: function(response, status){ alert(response.responseText); } }); }) Any suggestions on how to get IE to stop timing out or to accomplish this task without rewriting all my jQuery functions would be appreciated.

  • drupal ajax create node

    - by Mark
    I need to create a drupal node via ajax. I'm looking for some instructions as in: http://stackoverflow.com/questions/960343/creating-a-drupal-node-with-javascript But with more detail, and including the js steps. The JS will probably look something like this: var title = 'Demo Node Title' $('button').click(function () { $.post('demo/js', {"title" : title}, function(data) { var json = eval("(" + data + ")"); if (json['status'] == "error") { alert(json['message']); } else if (json['status'] == "success") { alert(json['message']); // Need to return the nid of the new node here. Anyone know how to do this? } }); }); The PHP (copied from the other question, but I don't understand it much, how do I set the title of the node? also as the comments says, how do I set an input filter?): <?php /** * Implementation of hook_menu(). */ function demo_menu() { $items = array(); $items['demo/js'] = array( 'title' => 'Demo page', 'page callback' => 'demo_js_page', 'access callback' => TRUE, 'type' => MENU_CALLBACK, ); return $items; } /** * Page callback that saves a node. */ function demo_js_page() { if (isset($_REQUEST['title'])) { $node = new stdClass; $node->type = 'blog'; $node->title = check_plain($_REQUEST['title']); node_save($node); drupal_set_message(t('Created node %title', array('%title' => $_REQUEST['title']))); } return t('Thanks for visiting'); } Thanks in advance.
