  • Multiple queries using same datacontext throws SqlException

    - by Raj
    I've search control with which I'm trying to implement search as user types something. I'm using Linq to SQL to fire queries against the database. Though it works fine usually, when user types the queries really fast some random SqlException is thrown. These are the two different error message I stumbled across recently: A severe error occurred on the current command. The results, if any, should be discarded. Invalid attempt to call Read when reader is closed. Edit: Included code DataContextFactory class: public DataContextFactory(IConnectionStringFactory connectionStringFactory) { this.dataContext = new RegionDataContext(connectionStringFactory.ConnectionString); } public DataContext Context { get { return this.dataContext; } } public void SaveAll() { this.dataContext.SubmitChanges(); } Registering IDataContextFactory with Unity // Get connection string from Application.Current settings ConnectionInfo connectionInfo = Application.Current.Properties["ConnectionInfo"] as ConnectionInfo; // Register ConnectionStringFactory with Unity container as a Singleton this.container.RegisterType<IConnectionStringFactory, ConnectionStringFactory>(new ContainerControlledLifetimeManager(), new InjectionConstructor(connectionInfo.ConnectionString)); // Register DataContextFactory with Unity container this.container.RegisterType<IDataContextFactory, DataContextFactory>(); Connection string: Data Source=.\SQLEXPRESS2008;User Instance=true;Integrated Security=true;AttachDbFilename=C:\client.mdf;MultipleActiveResultSets=true; Using datacontext from a repository class: // IDataContextFactory dependency is injected by Unity public CompanyRepository(IDataContextFactory dataContextFactory) { this.dataContextFactory = dataContextFactory; } // return List<T> of companies var results = this.dataContextFactory.Context.GetTable<CompanyEntity>() .Join(this.dataContextFactory.Context.GetTable<RegionEntity>(), c => c.regioncode, r => r.regioncode, (c, r) => new { c = c, r = r }) .Where(t => t.c.summary_region != null) .Select(t => new { Id = t.c.compcode, Company = t.c.compname, Region = t.r.regionname }).ToList(); What is the work around?

  • Rails - eager load the number of associated records, but not the record themselves.

    - by Max Williams
    I have a page that's taking ages to render out. Half of the time (3 seconds) is spent on a .find call which has a bunch of eager-loaded associations. All i actually need is the number of associated records in each case, to display in a table: i don't need the actual records themselves. Is there a way to just eager load the count? Here's a simplified example: @subjects = Subject.find(:all, :include => [:questions]) In my table, for each row (ie each subject) i just show the values of the subject fields and the number of associated questions for each subject. Can i optimise the above find call to suit these requirements? I thought about using a group field but my full call has a few different associations included, with some second-order associations, so i don't think group by will work. @subjects = Subject.find(:all, :include => [{:questions => :tags}, {:quizzes => :tags}], :order => "subjects.name") :tags in this case is a second-order association, via taggings. Here's my associations in case it's not clear what's going on. Subject has_many :questions has_many :quizzes Question belongs_to :subject has_many :taggings has_many :tags, :through => :taggings Quiz belongs_to :subject has_many :taggings has_many :tags, :through => :taggings Grateful for any advice - max

  • activemessaging with stomp and activemq.prefetchSize=1

    - by Clint Miller
    I have a situation where I have a single activemq broker with 2 queues, Q1 and Q2. I have two ruby-based consumers using activemessaging. Let's call them C1 and C2. Both consumers subscribe to each queue. I'm setting activemq.prefetchSize=1 when subscribing to each queue. I'm also setting ack=client. Consider the following sequence of events: 1) A message that triggers a long-running job is published to queue Q1. Call this M1. 2) M1 is dispatched to consumer C1, kicking off a long operation. 3) Two messages that trigger short jobs are published to queue Q2. Call these M2 and M3. 4) M2 is dispatched to C2 which quickly runs the short job. 5) M3 is dispatched to C1, even though C1 is still running M1. It's able to dispatch to C1 because prefetchSize=1 is set on the queue subscription, not on the connection. So the fact that a Q1 message has already been dispatched doesn't stop one Q2 message from being dispatched. Since activemessaging consumers are single-threaded, the net result is that M3 sits and waits on C1 for a long time until C1 finishes processing M1. So, M3 is not processed for a long time, despite the fact that consumer C2 is sitting idle (since it quickly finishes with message M2). Essentially, whenever a long Q1 job is run and then a whole bunch of short Q2 jobs are created, exactly one of the short Q2 jobs gets stuck on a consumer waiting for the long Q1 job to finish. Is there a way to set prefetchSize at the connection level rather than at the subscription level? I really don't want any messages dispatched to C1 while it is processing M1. The other alternative is that I could create a consumer dedicated to processing Q1 and then have other consumers dedicated to processing Q2. But, I'd rather not do that since Q1 messages are infrequent--Q1's dedicated consumers would sit idle most of the day tying up memory.

  • What VC++ compiler/linker does when building a C++ project with Managed Extension

    - by ???
    The initial problem is that I tried to rebuild a C++ project with debug symbols and copied it to test machine, The output of the project is external COM server(.exe file). When calling the COM interface function, there's a RPC call failre: COMException(0x800706BE): The remote procedure call failed. According to the COM HRESULT design, if the FACILITY code is 7, it's actually a WIN32 error, and the win32 error code is 0x6BE, which is the above mentioned "remote procedure call failed". All I do is replace the COM server .exe file, the origin file works well. When I checked into the project, I found it's a C++ project with Managed Extension. When I checking the DLL with reflector, it shows there's 2 additional .NET assembly reference. Then I checked the project setting and found nothing about the extra 2 assembly reference. I turned on the show includes option of compiler and verbose library of linker, and try to analyze whether the assembly is indirectly referenced via .h file. I've collect all the .h file and grep all the files with '#using' '#import' and the assembly file itself. There really is a '#using ' in one of the .h file but not-relevant to the referenced assembly. And about the linked .lib library files, only one of the .lib file is a side-product of another managed-extension-enabled C++ project, all others are produced by a pure, traditional C++ project. For the managed-extension-enabled C++ project, I checked the output DLL assembly, it did NOT reference to the 2 assembly. I even try to capture the access of the additional assembly file via sysinternal's filemon and procmon, but the rebuild process does NOT access these file. I'm very confused about the compile and linking process model of a VC++/CLI project, where the additional assembly reference slipped into the final assembly? Thanks in advance for any of your help.

  • PHPExcel reading columns

    - by user1270150
    I am new to using the PHPExcel and am struggling to implement a basic reader that can be used to read only specified columns, with all rows from a spreadsheet into an array, which I would like to present in a webpage. After reading the supplied documentation and examples, I am struggling to wrap my head round the implementation of a number of examples, so any help would be much appreciated. I am using the following code to get the contents of the default worksheet into an array: for ($row = 2; $row <= $highestRow; $row++) { $dataRow = $objWorksheet->rangeToArray('A'.$row.':'.$highestColumn.$row,null, true, true, true); if ((isset($dataRow[$row]['A'])) && ($dataRow[$row]['A'] > '')) { ++$r; foreach($headingsArray as $columnKey => $columnHeading) { $columnHeading = rtrim($columnHeading); $columnHeading = preg_replace('/\s+/', ' ',$columnHeading); $columnHeading = preg_replace('/\ /', '_',$columnHeading); $columnHeading = strtolower($columnHeading); $namedDataArray[$r][$columnHeading] = $dataRow[$row][$columnKey]; } } } Above code reads through all the columns and rows and builds and array, but I would like to be able to add a configuration array that will declare columns that should be read...sure this is possible, so any help would be much appreciated. Thanks

  • Rendering of graphics different depending on DisplayObject position

    - by jedierikb
    When drawing vertical lines with a non-integer x-value (e.g., 1.75) to a sprite, the lines are drawn differently based on the non-integer x-value of the sprite. In the picture below are two pairs of very close together vertical lines. As you can see, they look very different. This is frustrating, especially when animating the sprite. Any ideas how ensure that sprites-with-non-integer-positions' graphics will visually display the same way regardless of the sprite position? package { import flash.display.Sprite; import flash.display.StageAlign; import flash.display.StageScaleMode; import flash.events.Event; public class tmp extends Sprite { private var _sp1:Sprite; private var _sp2:Sprite; public function tmp( ):void { stage.align = StageAlign.TOP_LEFT; stage.scaleMode = StageScaleMode.NO_SCALE; _sp1 = new Sprite( ); drawButt( _sp1 ); _sp1.x = 100; _sp1.y = 100; _sp2 = new Sprite( ); drawButt( _sp2 ); _sp2.x = 100; _sp2.y = 200; addChild( _sp1 ); addChild( _sp2 ); addEventListener( Event.ENTER_FRAME, efCb, false, 0, true ); } private function efCb( evt:Event ):void { var nx:Number = _sp2.x + .1; if (nx > 400) { nx = 100; } _sp2.x = nx; } private function drawButt( sp:Sprite ):void { sp.graphics.clear( ); sp.graphics.lineStyle( 1, 0, 1, true ); sp.graphics.moveTo( 1, 1 ); sp.graphics.lineTo( 1, 100 ); sp.graphics.lineStyle( 1, 0, 1, true ); sp.graphics.moveTo( 1.75, 1 ); sp.graphics.lineTo( 1.75, 100 ); } } }

  • Function parameters evaluation order: is undefined behaviour if we pass reference?

    - by bolov
    This is undefined behaviour: void feedMeValue(int x, int a) { cout << x << " " << a << endl; } int main() { int a = 2; int &ra = a; feedMeValue(ra = 3, a); return 0; } because depending on what parameter gets evaluated first we could call (3, 2) or (3, 3). However this: void feedMeReference(int x, int const &ref) { cout << x << " " << ref << endl; } int main() { int a = 2; int &ra = a; feedMeReference(ra = 3, a); return 0; } will always output 3 3 since the second parameter is a reference and all parameters have been evaluated before the function call, so even if the second parameter is evaluated before of after ra = 3, the function received a reference to a wich will have a value of 2 or 3 at the time of the evaluation, but will always have the value 3 at the time of the function call. Is the second example UB? It is important to know because the compiler is free to do anything if he detects undefined behaviour, even if I know it would always yield the same results. *Note: I think that feedMeReference(a = 3, a) is the exact same situation as feedMeReference(ra = 3, a). However it seems not everybody agrees, in the addition to having 2 completely different answers.

  • How to suppress jqgrid from initially loading data?

    - by Steve Johnston
    I have a page that has a couple of jqGrids on it, along with a few other fields. I want to make one AJAX call myself that pulls back a JSON object that has the data that should be used to fill the entire page. So, I would like to make the call myself, populate the "other fields" and then pull a couple of collections off of the main JSON object that was returned and populate each of the jqGrids with those collections "manually". I have this much working, but I can't get jqGrid to stop attempting to make an AJAX request itself. Shouldn't there be a way to tell jqGrid to NOT attempt an AJAX call when it is initialized? I found a similar question asked here: http://stackoverflow.com/questions/1850159/how-to-suppress-jqgrid-from-initially-loading-data But I don't have the option that solved it for the poster. It seems pretty logical to me that some people may want to use this plugin without having the table attempt to get its own data upon initialization. Am I missing an option somewhere in the documentation (wiki - options)? Thanks.

  • Multiple SessionFactories in Windows Service with NHibernate

    - by Rob Taylor
    Hi all, I have a Webapp which connects to 2 DBs (one core, the other is a logging DB). I must now create a Windows service which will use the same business logic/Data access DLLs. However when I try to reference 2 session factories in the Service App and call the factory.GetCurrentSession() method, I get the error message "No session bound to current context". Does anyone have a suggestion about how this can be done? public class StaticSessionManager { public static readonly ISessionFactory SessionFactory; public static readonly ISessionFactory LoggingSessionFactory; static StaticSessionManager() { string fileName = System.Configuration.ConfigurationSettings.AppSettings["DefaultNHihbernateConfigFile"]; string executingPath = System.IO.Path.GetDirectoryName(System.Reflection.Assembly.GetExecutingAssembly().GetName().CodeBase); fileName = executingPath + "\\" + fileName; SessionFactory = cfg.Configure(fileName).BuildSessionFactory(); cfg = new Configuration(); fileName = System.Configuration.ConfigurationSettings.AppSettings["LoggingNHihbernateConfigFile"]; fileName = executingPath + "\\" + fileName; LoggingSessionFactory = cfg.Configure(fileName).BuildSessionFactory(); } } The configuration file has the setting: <property name="current_session_context_class">call</property> The service sets up the factories: private ISession _session = null; private ISession _loggingSession = null; private ISessionFactory _sessionFactory = StaticSessionManager.SessionFactory; private ISessionFactory _loggingSessionFactory = StaticSessionManager.LoggingSessionFactory; ... _sessionFactory = StaticSessionManager.SessionFactory; _loggingSessionFactory = StaticSessionManager.LoggingSessionFactory; _session = _sessionFactory.OpenSession(); NHibernate.Context.CurrentSessionContext.Bind(_session); _loggingSession = _loggingSessionFactory.OpenSession(); NHibernate.Context.CurrentSessionContext.Bind(_loggingSession); So finally, I try to call the correct factory by: ISession session = StaticSessionManager.SessionFactory.GetCurrentSession(); Can anyone suggest a better way to handle this? Thanks in advance! Rob

  • python can't start a new thread

    - by Giorgos Komnino
    I am building a multi threading application. I have setup a threadPool. [ A Queue of size N and N Workers that get data from the queue] When all tasks are done I use tasks.join() where tasks is the queue . The application seems to run smoothly until suddently at some point (after 20 minutes in example) it terminates with the error thread.error: can't start new thread Any ideas? Edit: The threads are daemon Threads and the code is like: while True: t0 = time.time() keyword_statuses = DBSession.query(KeywordStatus).filter(KeywordStatus.status==0).options(joinedload(KeywordStatus.keyword)).with_lockmode("update").limit(100) if keyword_statuses.count() == 0: DBSession.commit() break for kw_status in keyword_statuses: kw_status.status = 1 DBSession.commit() t0 = time.time() w = SWorker(threads_no=32, network_server='http://192.168.1.242:8180/', keywords=keyword_statuses, cities=cities, saver=MySqlRawSave(DBSession), loglevel='debug') w.work() print 'finished' When the daemon threads are killed?

  • Default boolean value in a array of record - Delphi

    - by James
    Hi, I am helping out my company with some old delphi 7 code. There is a record declared at the start that is used throughout to store all the data we want outputted. type TOutput_Type = record result: String; resultoffset: String; selected: boolean; resultcategory: integer; end; and then an array of this is declared Output: array of TOutput_Type; The length is set at the start to a large value, as actual length is unknown. This array is used all over the place, but unfortunately the value selected is not always set when used. My problem is I am adding in a summary of the data, but because selected is not set, delphi seems to give it a random true or false status. Is there a way of setting all instances of selected as true at the start? Seems like a simple enough thing to do, but I'm not a delphi programmer so am unsure if its possible? I know I can go through and add in selected := true every time a new record is made, but I'd like to do it cleanly at the start if possible.... Thanks in advance

  • Why is Delphi unable to infer the type for a parameter TEnumerable<T>?

    - by deepc
    Consider the following declaration of a generic utility class in Delphi 2010: TEnumerableUtils = class public class function InferenceTest<T>(Param: T): T; class function Count<T>(Enumerable: TEnumerable<T>): Integer; overload; class function Count<T>(Enumerable: TEnumerable<T>; Filter: TPredicate<T>): Integer; overload; end; Somehow the compiler type inference seems to have problems here: var I: Integer; L: TList<Integer>; begin TEnumerableUtils.InferenceTest(I); // no problem here TEnumerableUtils.Count(L); // does not compile: E2250 There is no overloaded version of 'Count' that can be called with these arguments TEnumerableUtils.Count<Integer>(L); // compiles fine end; The first call works as expected and T is correctly inferred as Integer. The second call does not work, unless I also add <Integer -- then it works, as can be seen in the third call. Am I doing something wrong or is the type inference in Delphi just not supporting this (I don't think it is a problem in Java which is why expected it to work in Delphi, too).

  • How to benchmark on multi-core processors

    - by Pascal Cuoq
    I am looking for ways to perform micro-benchmarks on multi-core processors. Context: At about the same time desktop processors introduced out-of-order execution that made performance hard to predict, they, perhaps not coincidentally, also introduced special instructions to get very precise timings. Example of these instructions are rdtsc on x86 and rftb on PowerPC. These instructions gave timings that were more precise than could ever be allowed by a system call, allowed programmers to micro-benchmark their hearts out, for better or for worse. On a yet more modern processor with several cores, some of which sleep some of the time, the counters are not synchronized between cores. We are told that rdtsc is no longer safe to use for benchmarking, but I must have been dozing off when we were explained the alternative solutions. Question: Some systems may save and restore the performance counter and provide an API call to read the proper sum. If you know what this call is for any operating system, please let us know in an answer. Some systems may allow to turn off cores, leaving only one running. I know Mac OS X Leopard does when the right Preference Pane is installed from the Developers Tools. Do you think that this make rdtsc safe to use again? More context: Please assume I know what I am doing when trying to do a micro-benchmark. If you are of the opinion that if an optimization's gains cannot be measured by timing the whole application, it's not worth optimizing, I agree with you, but I cannot time the whole application until the alternative data structure is finished, which will take a long time. In fact, if the micro-benchmark were not promising, I could decide to give up on the implementation now; I need figures to provide in a publication whose deadline I have no control over.

  • loading google maps drawing manager object

    So i am using Google Maps Drawing Manager to draw some polygons and i am saving the lat e long coordinates to my database. Now my question is, after i load that to my array, how can i rebuild the saved polygon back into my map? I can't seem to find a code to understand that. this is what i have now : window.initialize_2 = function () { var mapOptions = { center: new google.maps.LatLng(-34.397, 150.644), zoom: 8, mapTypeId: google.maps.MapTypeId.ROADMAP }; var map = maplimits; var drawingManager = new google.maps.drawing.DrawingManager({ drawingMode: google.maps.drawing.OverlayType.MARKER, drawingControl: true, drawingControlOptions: { position: google.maps.ControlPosition.TOP_CENTER, drawingModes: [ google.maps.drawing.OverlayType.POLYGON] }, markerOptions: { icon: 'images/beachflag.png' }, polygonOptions: { fillColor: '#ffff00', fillOpacity: 10, strokeWeight: 5, clickable: true, editable: true, zIndex: 1 } }); var coord_listener = google.maps.event.addListener(drawingManager, 'polygoncomplete', function (polygon) { var coordinates = (polygon.getPath().getArray()); console.log(coordinates); window.poly = polygon; }); //delete shape google.maps.event.addListener(drawingManager, 'overlaycomplete', function (e) { if (e.type != google.maps.drawing.OverlayType.MARKER) { // Switch back to non-drawing mode after drawing a shape. drawingManager.setDrawingMode(null); // Add an event listener that selects the newly-drawn shape when the user // mouses down on it. var newShape = e.overlay; newShape.type = e.type; google.maps.event.addListener(newShape, 'click', function () { setSelection(newShape); }); setSelection(newShape); } }); // Clear the current selection when the drawing mode is changed, or when the // map is clicked. google.maps.event.addListener(drawingManager, 'drawingmode_changed', clearSelection); google.maps.event.addListener(map, 'click', clearSelection); drawingManager.setMap(map); }

  • Force sending a user to custom QuerySet.

    - by Jack M.
    I'm trying to secure an application so that users can only see objects which are assigned to them. I've got a custom QuerySet which works for this, but I'm trying to find a way to force the use of this additional functionality. Here is my Model: class Inquiry(models.Model): ts = models.DateTimeField(auto_now_add=True) assigned_to_user = models.ForeignKey(User, blank=True, null=True, related_name="assigned_inquiries") objects = CustomQuerySetManager() class QuerySet(QuerySet): def for_user(self, user): return self.filter(assigned_to_user=user) (The CustomQuerySetManager is documented over here, if it is important.) I'm trying to force everything to use this filtering, so that other methods will raise an exception. For example: Inquiry.objects.all() ## Should raise an exception. Inquiry.objects.filter(pk=69) ## Should raise an exception. Inquiry.objects.for_user(request.user).filter(pk=69) ## Should work. inqs = Inquiry.objects.for_user(request.user) ## Should work. inqs.filter(pk=69) ## Should work. It seems to me that there should be a way to force the security of these objects by allowing only certain users to access them. I am not concerned with how this might impact the admin interface.

  • Is Stream.Write thread-safe?

    - by Mike Spross
    I'm working on a client/server library for a legacy RPC implementation and was running into issues where the client would sometimes hang when waiting to a receive a response message to an RPC request message. It turns out the real problem was in my message framing code (I wasn't handling message boundaries correctly when reading data off the underlying NetworkStream), but it also made me suspicious of the code I was using to send data across the network, specifically in the case where the RPC server sends a large amount of data to a client as the result of a client RPC request. My send code uses a BinaryWriter to write a complete "message" to the underlying NetworkStream. The RPC protocol also implements a heartbeat algorithm, where the RPC server sends out PING messages every 15 seconds. The pings are sent out by a separate thread, so, at least in theory, a ping can be sent while the server is in the middle of streaming a large response back to a client. Suppose I have a Send method as follows, where stream is a NetworkStream: public void Send(Message message) { //Write the message to a temporary stream so we can send it all-at-once MemoryStream tempStream = new MemoryStream(); message.WriteToStream(tempStream); //Write the serialized message to the stream. //The BinaryWriter is a little redundant in this //simplified example, but here because //the production code uses it. byte[] data = tempStream.ToArray(); BinaryWriter bw = new BinaryWriter(stream); bw.Write(data, 0, data.Length); bw.Flush(); } So the question I have is, is the call to bw.Write (and by implication the call to the underlying Stream's Write method) atomic? That is, if a lengthy Write is still in progress on the sending thread, and the heartbeat thread kicks in and sends a PING message, will that thread block until the original Write call finishes, or do I have to add explicit synchronization to the Send method to prevent the two Send calls from clobbering the stream?

  • Incorrect logic flow? function that gets coordinates for a sudoku game

    - by igor
    This function of mine keeps on failing an autograder, I am trying to figure out if there is a problem with its logic flow? Any thoughts? Basically, if the row is wrong, "invalid row" should be printed, and clearInput(); called, and return false. When y is wrong, "invalid column" printed, and clearInput(); called and return false. When both are wrong, only "invalid row" is to be printed (and still clearInput and return false. Obviously when row and y are correct, print no error and return true. My function gets through most of the test cases, but fails towards the end, I'm a little lost as to why. bool getCoords(int & x, int & y) { char row; bool noError=true; cin>>row>>y; row=toupper(row); if(row>='A' && row<='I' && isalpha(row) && y>=1 && y<=9) { x=row-'A'; y=y-1; return true; } else if(!(row>='A' && row<='I')) { cout<<"Invalid row"<<endl; noError=false; clearInput(); return false; } else { if(noError) { cout<<"Invalid column"<<endl; } clearInput(); return false; } }

  • Using Ant how can I dex a directory of jars?

    - by cbeaudin
    I have a directory full of jars (felix bundles). I want to iterate through all of these jars and create dex'd versions. My intent is to deploy each of these dex'd jars as standalone apk's since they are bundles. Feel free to straighten me out if I am approaching this from the wrong direction. This first part is just to try and create a corresponding .dex file for each jar. However when I run this I am getting a "no resources specified" error coming out of Ant. Is this the right approach, or is there a simpler approach to just input a jar and output a dex'd version of that jar? The ${file} is valid as it is spitting out the name of the file in the echo command. <target name="dexBundles" description="Run dex on all the bundles"> <taskdef resource="net/sf/antcontrib/antlib.xml" classpath="${basedir}/libs/ant-contrib.jar" /> <echo>Starting</echo> <for param="file"> <path> <fileset dir="${pre.dex.dir}"> <include name="**/*.jar" /> </fileset> </path> <sequential> <echo message="@{file}" /> <echo>Converting jar file @{file} into ${post.dex.dir}/@{file}.class...</echo> <apply executable="${dx}" failonerror="true" parallel="true" verbose="true"> <arg value="--dex" /> <arg value="--output=${post.dex.dir}/${file}.dex" /> <arg path="@{file}" /> </apply> </sequential> </for> <echo>Finished</echo> </target>

I have been using a queue based solution which worked fine: import datetime from models import * DELETABLE_MODELS = [Alpha, Beta, AlphaBeta] def initiate_purge(): for e in config.DELETABLE_MODELS: deferred.defer(delete_entities, e, 'purging', _queue = 'purging') class NotEmptyException(Exception): pass def delete_entities(e, queue): try: q = e.all(keys_only=True) db.delete(q.fetch(200)) ct = q.count(1) if ct > 0: raise NotEmptyException('there are still entities to be deleted') else: logging.info('processing %s completed' % queue) except Exception, err: deferred.defer(delete_entities, e, then, queue, _queue = queue) logging.info('processing %s deferred: %s' % (queue, err)) All this does is queue a request to delete some data (once for each class) and then if the queued process either fails or knows there is still some stuff to delete, it re-queues itself. This beats the heck out of hitting the refresh on a browser for 10 minutes. However, I'm having trouble deleting AlphaBeta entities, there are always a few left at the end. I think because it contains Reference Properties: class AlphaBeta(db.Model): alpha = db.ReferenceProperty(Alpha, required=True, collection_name='betas') beta = db.ReferenceProperty(Beta, required=True, collection_name='alphas') I have tried deleting the indexes relating to these entity types, but that did not make any difference. Any advice would be appreciated please.

  • UIAlertView choice causing resignFirstResponder to fail

    - by Chazbot
    Hi everyone. I'm having a similar issue to Anthony Chan's question, and after trying every suggested solution, I'm still stuck. Somehow, only after interacting with my UIAlertView, I'm unable to dismiss the keyboard in another view of my app. It's as though the Alert is breaking my UITextField's ability to resignFirstResponder. Below I instantiate my UIAlertView, which then calls its didDismissWIthButtonIndex method. Then, I call the showInfo method, which loads another UIViewController. UIAlertView *emailFailAlert = [[UIAlertView alloc] initWithTitle:@"Error" message:@"error message text." delegate:self cancelButtonTitle:@"Not now" otherButtonTitles:@"Settings", nil]; [emailFailAlert setTag:2]; [emailFailAlert show]; [emailFailAlert release]; Once the 'Settings' option is pressed, I'm calling this method: - (void)alertView:(UIAlertView *)alertView didDismissWithButtonIndex:(NSInteger)buttonIndex { if ([alertView tag] == 2) { if (buttonIndex == 1){ [self showInfo:nil]; } } } My showInfo method loads the other ViewController, via the code below: - (IBAction)showInfo:(id)sender { FlipsideViewController *fscontroller = [[FlipsideViewController alloc] initWithNibName:@"FlipsideView" bundle:nil]; fscontroller.delegate = self; fscontroller.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal; [self presentModalViewController:fscontroller animated:YES]; [fscontroller release]; } Upon clicking any textField in this Flipside VC, I'm unable to dismiss the keyboard as I normally can with - (BOOL)textFieldShouldReturn:(UITextField *)textField, and [textField resignFirstResponder]. I've omitted this code bc this question is getting long, but I'm happy to post if necessary. The interesting part is that if I comment out the [self showInfo:nil] call made when the button is clicked and call it by clicking a test button (outside the alertView didDismissWithButtonIndex: method), everything works fine. Any idea what's happening here? Thanks in advance!

  • Dynamic Hierarchical Javascript Object Loop

    - by user1684586
    var treeData = {"name" : "A", "children" : [ {"name" : "B", "children": [ {"name" : "C", "children" :[]} ]} ]}; THE ARRAY BEFORE SHOULD BE EMPTY. THE ARRAY AFTER SHOULD BE POPULATED DEPENDING ON THE NUMBER OF NODES NEEDED THAT WILL BE DEFINED FROM A DYNAMIC VALUE THAT IS PASSED. I would like to build the hierarchy dynamically with each node created as a layer/level in the hierarchy having its own array of nodes. THIS SHOULD FORM A TREE STRUCTURE. This is hierarchy structure is described in the above code. This code has tree level simple for demonstrating the layout of the hierarchy of values. There should be a root node, and an undefined number of nodes and levels to make up the hierarchy size. Nothing should be fixed besides the root node. I do not need to read the hierarchy, I need to construct it. The array should start {"name" : "A", "children" : []} and every new node as levels would be created {"name" : "A", "children" : [HERE-{"name" : "A", "children" : []}]}. In the child array, going deeper and deeper. Basically the array should have no values before the call, except maybe the root node. After the function call, the array should comprise of the required nodes of a number that may vary with every call. Every child array will contain one or more node values. There should be a minimum of 2 node levels, including the root. It should initially be a Blank canvas, that is no predefined array values.

  • Keeping dates in order when using date_select and discarding year in Rails?

    - by MikeH
    My app has users who have seasonal products. When a user selects a product, we allow him to also select the product's season. We accomplish this by letting him select a start date and an end date for each product. We're using date_select to generate two sets of drop-downs: one for the start date and one for the end date. Including years doesn't make sense for our model. So we're using the option: discard_year => true To explain our problem, consider that our products are apples. Vendor X carries apples every year from September to January. Years are irrelevant here, and that's why we're using discard_year => true. However, while the specific years are irrelevant, the relative point in time from the start date to the end date is relevant. This is where our problem arises. When you use discard_year => true, Rails does set a year in the database, it just doesn't appear in the views. Rails sets all the years to 0001 in our app. Going back to our apple example, this means that the database now thinks the user has selected September 0001 to January 0001. This is a problem for us for a number of reasons. To solve this, the logic that I need to implement is the following: - If season_start month/date is before season_end month/date, then standard Rails approach is fine. - But, if season_start month/date is AFTER season_end month/date, then I need to dynamically update the database field such that the year for season_end is equal to the year for season_start + 1. My best guess is that I would create a custom method that runs as an after_save or after_update in my products model. But I'm not really sure how to do this. Ideas? Anybody ever had this issue? Thanks!
