  • More strict query yields more results?

    - by Mark
    I've got a query that looks like this affiliates = User.objects.annotate(referral_count=Count('referrals')).filter(referral_count__gt=0) But when I restrict it more by adding referrals__user__date_joined__gt=start_date to the filter, I get even higher referral counts. I'm trying to count the number of people a user has referred within a time period. The relevant model looks like this: class Profile(models.Model): user = models.ForeignKey(User, unique=True, related_name='profile') referred_by = models.ForeignKey(User, null=True, blank=True, related_name='referrals') In contrast, when I try it like this: affiliates = User.objects \ .exclude(referrals__user__date_joined__lte=sd, referrals__user__date_joined__gt=ed) \ .annotate(referral_count=Count('referrals')) \ .filter(referral_count__gt=0) The exclude statement seems to do nothing... the counts don't change (should be 0 if no referred users have joined within that time period, but it isn't).

  • is my function correct?

    - by sbsp
    This is part of an assignment so please dont post solutions, just point me in the right direction if possible? I am passing a pointer to a char array to my method, as well as a value for the actual height of the char array. I am looping through to see if all values are 0, if they are then return 0, esle return one The method is used as a test to see if i should free memory or not and set the pointer to null if it is full of 0's. The issue i am having is that the programme should have "some unfree" memory at the end, so i have no idea whether or not its doing it correctly - and gdb i struggle with immensley. Thanks for reading int shouldBeNull(char *charPointer, int sizeOfCharArray) { int isIn = 0; int i = 0; while(i < sizeOfCharArray){ if(*charPointer != '0'){ isIn = 1; break; } i++; charPointer++; } return isIn; }

  • How to turn this linq query to lazy loading

    - by Luke101
    I would like to make a certain select item to lazy load latter in my linq query. Here is my query var posts = from p in context.post where p.post_isdeleted == false && p.post_parentid == null select new { p.post_date, p.post_id, p.post_titleslug, p.post_votecount, FavoriteCount = context.PostVotes.Where(x => x.PostVote_postid == p.post_id).Count() //this should load latter }; I have deleted the FavoriteCount item in the select query and would like it to ba added later based on certain conditions. Here is the way I have it lazy loaded if (GetFavoriteInfo) { posts = posts.Select(x => new { FavoriteCount = context.PostVotes.Where(y => y.PostVote_postid == x.post_id).Count() }); } I am getting a syntax error with this the above query. How do I fix this

  • DataGrid: How to style or disable the default ContextMenu of a Cell

    - by Nike
    I use DataGrid with DataGridTextColumns. How can I style or disable the default ContextMenu of a Cell? I tried to add a style for DataGridCell: <DataGrid.CellStyle> <Style TargetType="{x:Type DataGridCell}"> <Setter Property="ContextMenu" Value="{x:Null}"/> </Style> </DataGrid.CellStyle> but it doesn't work. As I understand, it is a TextBox inside a Cell when the Cell in edit mode. I tried also to add a style for TextBox, but it have an effect only on TextBoxes in XAML, but not on the DataGrid cells.

    - by Helpme
    Hi! I'm purposely targeting Java OS 1.4.2 I'm trying to use an iterator combined with apache's POI to read an excel spreadsheet. The code runs perfectly in java 1.5, but in the 1.4.2 version I get the error listed in the question subject. the code is: Iterator myIter = null; it breaks on that line of code, which is clearly at the beginning of the application. I dont understand what needs to be done to correct this issue. Please let me know if you have any insight!

  • IDispatchMessageInspector to log plain-text soap messages?

    - by Dan Thomas
    I've written a WCF IDispatchMessageInspector, so I can log incomming and outgoing messages. But I'm not sure how to get a nicely-formatted XML string to log. My code looks something like this: public object AfterReceiveRequest(ref Message request, IClientChannel channel, InstanceContext instanceContext) { MessageBuffer buffer = request.CreateBufferedCopy(Int32.MaxValue); request = buffer.CreateMessage(); Log("Received", request.ToString(); return null; } The result of this logging includes things like "ampersand lt;" and some sort of binary-encoded data. How do I get something that looks like a standard soap XML document? I know this should be obvious, but I'm just too dense to figure it out. Thanks. Dan

  • database table in Magento does not exist: sales_flat_shipment_grid

    - by dene
    We're using Magento 1.4.0.1 and want to use an extension from a 3rd party developer. The extension does not work, because of a join to the table "sales_flat_shipment_grid": $collection = $model->getCollection()->join('sales/shipment_grid', 'increment_id=shipment', array('order_increment_id'=>'order_increment_id', 'shipping_name' =>'shipping_name'), null,'left'); Unfortunately this table does not exist n our database. So the error "Can't retrieve entity config: sales/shipment_grid" appears. If I comment this part out, the extension is working, but I guess, it does not proper work. Does anybody know something about this table? There are a backend-option for the catalog to use the "flat table" option, but this is only for the catalog. And the tables already exists, no matter which option is checked. Thank you a lot! :-)

  • java: relationship of the Runnable and Thread interfaces

    - by Karl Patrick
    I realize that the method run() must be declared because its declared in the Runnable interface. But my question comes when this class runs how is the Thread object allowed if there is no import call to a particular package? how does runnable know anything about Thread or its methods? does the Runnable interface extend the Thread class? Obviously I don't understand interfaces very well. thanks in advance. class PrimeFinder implements Runnable{ public long target; public long prime; public boolean finished = false; public Thread runner; PrimeFinder(long inTarget){ target = inTarget; if(runner == null){ runner = new Thread(this); runner.start() } } public void run(){ } }

  • Is it possible to use flashvars with JBoss?

    - by Aikanaro
    Hi, I'm part of a team developing a product using JSF 2.0 and I was asked to investigate the possibility of including FusionCharts free in the app. I have tried different ways of inserting a simple chart in a JSF page but with no luck. On of the methods involves using the elements OBJECT and EMBED but hhen I try to use them I get a "null source" error from JBoss. From what I could find online (through Google), I am under the impression that 'flashvars' isn't quite compatible with JBoss. Is anyone here able to confirm this? If this is the case, what workaround would you suggest me? Other ways I also found online didn't show the chart not even an error message. Thanks in advance.

  • Newbie PHP coding problem: header function (maybe, I need someone to check my code)

    - by Haskella
    Hi, consider the following PHP code: <?php $searchsport = $_REQUEST['sport']; $sportarray = array( "Football" => "Fb01", "Cricket" => "ck32", "Tennis" => "Tn43", ); header("Location: ".$sportarray[$searchsport].".html"); //directs user to the corresponding page they searched if ($searchsport == NULL) { header("Location: youtypednothing.html"); //directs user to a page I've set up to warn them if they've entered nothing } else { header("Location: sportdoesnotexist.html"); //if sport isn't in my root, a warning will appear } ?> I think the code comments are self-explanatory, basically when I type Tennis on my form.html it will send data to this php file and process and direct me to Tn43.html which is my tennis page. Unfortunately, it doesn't work and I really want to know why... (I know I've made some huge silly mistake). PS: Is header the right function to use when doing some redirecting?

  • Hidden Input Elements in Firefox

    - by splatto
    I'm having troubles with fckeditor in Firefox. When the user goes to a page, the html (encoded) is stored in a hidden input element. I call the predefined fckeditor javascript event to populate my editor with the html from the hidden ContentBody element. function FCKeditor_OnComplete( editorInstance ) { editorInstance.InsertHtml(""); var sample = document.getElementById("ContentBody").value; editorInstance.InsertHtml(sample); } This automatically populates the editor with the desired text in IE, but in Firefox it doesn't. Firebug gives me the error : A is null [Break on this error] var FCKW3CRange=function(A){this._Docume...eateFromRange(this._Document,this);}};\r\n Using Firebug I can determine that the event method FCKeditor_OnComplete() just isn't fired when using Firefox. It is, however, in IE. Any ideas on how to get this to work in both browsers? The HTML for ContentBody is: <input type="hidden" name="ContentBody" id="ContentBody" value="<%=Model.Article%>" />

  • Expression.Call() to String.Equals() throws error

    - by Sam
    The following code: var constant = Expression.Constant("find me", typeof(string)); // memberExpression evaluates to a string var predicate = Expression.Call(memberExpression, "Equals", null, constant); is throwing the error More than one method 'Equals' on type 'System.String' is compatible with the supplied arguments. I'm guessing that's because there's Equals(Object) and Equals(String) - is there any way for me to specify which method I mean to use via the overload of Expression.Call() that takes an instance method name as a string? Or do I have to make a special case for calls to Equals() to take a MethodInfo instead?

  • asp.net disappearing data from Dropdownlist inside listview when loading from DataTable

    - by piotrmichal
    Hello I have a problem with dropdowllist ddl1 that is inside of insertitem of listview. I populate it from table on page load. In Page_load I have: if (!Page.IsPostBack) { ListView1.DataBind(); InsDropDownList3.DataSource = GetAllPlayersName(); InsDropDownList3.DataBind(); } DropDownList ddl1 = (DropDownList)ListView1.InsertItem.FindControl("InsDropDownList1"); if (ddl1 != null) { DataTable t = GetAllPlayersName(); ddl1.DataSource = t; ddl1.DataBind(); } When I select a row in listview or edit it data from dropdownlist in insertitem row disappears - list became empty until I close page and open again. There is another InsDropDownList3 outside of listview and there is no problem with this one. Why one is loosing data and the other one not? As I understand ddl1 should even get data every time page loads.

  • MySQL Trigger with dynamic table name

    - by Thomas
    I've look around a bit and can't quite find an answer to my problem: I want a trigger to execute after an insert on a table and to take that data that is being inserted and do two things Create a new table from the client id and partner id Insert the 'data' that just was inserted into the new table I am fairly new to the Stored procedures and triggers so I came up with this but am having difficulty debugging it: delimiter $$ CREATE TRIGGER trg_creas_insert BEFORE INSERT ON tracking.creas for each row BEGIN DECLARE @tableName varchar(40); DECLARE @createStmnt mediumtext; SET @tableName = concat('crea_','_', NEW.idClient_crea,'_',NEW.idPartenaire_crea); SET @createStmnt = concat('CREATE TABLE IF NOT EXISTS', @tableName, '( `data_crea` mediumtext NOT NULL ) ENGINE=MyISAM AUTO_INCREMENT=29483330 DEFAULT CHARSET=utf8 PACK_KEYS=0'); PREPARE stmt FROM @createStmnt; EXECUTE stmt; INSERT INTO @tableName (data_crea) values (NEW.data_crea); END$$ delimiter ; Thoughts?

  • Application_End() cannot access cache through HttpContext.Current.Cache[key]

    - by Carl J.
    I want to be able to maintain certain objects between application restarts. To do that, I want to write specific cached items out to disk in Global.asax Application_End() function and re-load them back on Application_Start(). I currently have a cache helper class, which uses the following method to return the cached value: return HttpContext.Current.Cache[key]; Problem: during Application_End(), HttpContext.Current is null since there is no web request (it's an automated cleanup procedure) - therefore, I cannot access .Cache[] to retrieve any of the items to save to disk. Question: how can I access the cache items during Application_End()?

  • Upgrading website from VS2005(2.0 Framework) to VS2008(2.0 Framework)

    - by Sravan
    We have a website that is created in VS2005 Recently we upgraded the website to VS2008 with 2.0 framework. While compiling the website Compilation errors are occuring i.e Licenses.licx file is not compiling, if it compile than it will reproduces an AppLicenses.dll. In the licensing.licx file containing one class and a namespace(i.e. OSADirectLicensing.OSADirectLicensedClass, OSADirectLicensing). The compilation error is as follows: Error 1 C:\Program Files\Sharp\Sharp Developer Tools\OSA SDK\Samples\DirectOSA\ExternalAuthority\licenses.licx: Could not transform licenses file into a binary resource. (1) : error LC0004 : Exception occurred creating type 'OSADirectLicensing.OSADirectLicensedClass, OSADirectLicensing, Version=1.0.4006.31768, Culture=neutral, PublicKeyToken=null System.ComponentModel.LicenseException: Invalid License at System.ComponentModel.LicenseManager.CreateWithContext(Type type, LicenseContext creationContext, Object[] args) at System.ComponentModel.LicenseManager.CreateWithContext(Type type, LicenseContext creationContext) at System.Tools.LicenseCompiler.GenerateLicenses(String fileContents, String targetPE, ITypeResolutionService resolver, DesigntimeLicenseContext ctx)' . Does VS2008 support licenses.licx or not? We should not remove this file from website. How can we solve this issue?

  • Is there a standard .NET exception to throw when a class doesn't implement a required attribute?

    - by a typing monkey
    Suppose I want to throw a new exception when invoking a generic method with a type that doesn't have a required attribute. Is there a .NET exception that's appropriate for this situation, or, more likely, one that would be a suitable ancestor for a custom exception? For example: public static class ClassA { public static T DoSomething<T>(string p) { Type returnType = typeof(T); object[] typeAttributes = returnType.GetCustomAttributes(typeof(SerializableAttribute), true); if ((typeAttributes == null) || (typeAttributes.Length == 0)) { // Is there an exception type in the framework that I should use/inherit from here? throw new Exception("This class doesn't support blah blah blah"); // Maybe ArgumentException? That doesn't seem to fit right. } } } Thanks.

  • Order of calls to set functions when invoking a flex component

    - by Jason
    I have a component called a TableDataViewer that contains the following pieces of data and their associated set functions: [Bindable] private var _dataSetLoader:DataSetLoader; public function get dataSetLoader():DataSetLoader {return _dataSetLoader;} public function set dataSetLoader(dataSetLoader:DataSetLoader):void { trace("setting dSL"); _dataSetLoader = dataSetLoader; } [Bindable] private var _table:Table = null; public function set table(table:Table):void { trace("setting table"); _table = table; _dataSetLoader.load(_table.definition.id, "viewData", _table.definition.id); } This component is nested in another component as follows: <ve:TableDataViewer width="100%" height="100%" paddingTop="10" dataSetLoader="{_openTable.dataSetLoader}" table="{_openTable.table}"/> Looking at the trace in the logs, the call to set table is coming before the call to set dataSetLoader. Which is a real shame because set table() needs dataSetLoader to already be set in order to call its load() function. So my question is, is there a way to enforce an order on the calls to the set functions when declaring a component?

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

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

  • WPF Image Button formatting

    - by Sonic Soul
    If I create a button with an image inside, it gets blown up to much larger size than the image. If i try to constrain the size of image, and container button, the image gets cut off: <Button Background="Transparent" Width="18" Height="18" Margin="0,0,0,0" Padding="0,0,0,0" BorderBrush="{x:Null}"> <Image Width="16" Height="16" /> </Button> Native image size is 16x16. Here the button is 18x18 with 0 padding, yet the image still gets cut-off on right/bottom. how can i make the entire button be exactly the size of the image w/out any cut off?

  • IE error with jquery counter plugin

    - by Mankey
    I've implemented a jquery counter script (count up from say 50 to 100 with different increments) that I found from this question: jQuery counter to count up to a target number The scripts works great except for in Internet Explorer 8 (and possibly other IE versions?). Here's an error message from IE with the URL to the creator of the script's demo. Message: 'undefined' is null or not an object Line: 32 Char: 17 Code: 0 URI: http://www.ulmanen.fi/stuff/counter.php I'm just wondering if anyone know how this can be fixed. I'm guessing it has to do with el.html() not finding any data but I can't really figure this out. Thanks for any help ^^ I would reply to that post if I could but I can't seem to find any way of doing so (I'm new to stackoverflow, I think I lack privileges).

  • How can i supply an AntiForgeryToken when posting JSON data using $.ajax ?

    - by HerbalMart
    I am using the code as below of this post: First i will an fill array variable with the correct values for the controller action. Using the code below i think it should be very straigtforward by just adding the following line to the javascript: data["__RequestVerificationToken"] = $('[name=__RequestVerificationToken]').val(); The <%= Html.AntiForgeryToken() %> is at his right place and the action has a [ValidateAntiForgeryToken] But my controller action keeps saying: "Invalid forgery token" What am i doing wrong here? Code data["fiscalyear"] = fiscalyear; data["subgeography"] = $(list).parent().find('input[name=subGeography]').val(); data["territories"] = new Array(); $(items).each(function() { data["territories"].push($(this).find('input[name=territory]').val()); }); if (url != null) { $.ajax( { dataType: 'JSON', contentType: 'application/json; charset=utf-8', url: url, type: 'POST', context: document.body, data: JSON.stringify(data), success: function() { refresh(); } }); }

  • CodeIgniter: json_decode array issues

    - by thedp
    On my client side I'm sending an ajax request with jQuery in the following matter: $.post(script.php, { "var1":"something", "var2":"[1,2,3]" }, function(data) { }, "json"); On the server side, in the CodeIgniter's controller I'm receiving the values like so: $var1 = trim($this->input->post('var1')); $var2 = trim($this->input->post('var2')); My question is how do I convert the string in $var2 into a PHP array. I tried using json_decode($var2, true) but it returns a null since "[1,2,3]" is not a legal JSON string by itself. Also, if you believe there is a better way for me to read the values on the server-side please show me how. Thank you.

  • Get enum by it's inner field

    Hi! Have enum with inner fields, kind of map. Now I need to get enum by it's inner field. Wrote this: package test; /** * Test enum to test enum =) */ public enum TestEnum { ONE(1), TWO(2), THREE(3); private int number; TestEnum(int number) { this.number = number; } public TestEnum findByKey(int i) { TestEnum[] testEnums = TestEnum.values(); for (TestEnum testEnum : testEnums) { if (testEnum.number == i) { return testEnum; } } return null; } } But it's not very efficient to look up through all enums each time I need to find appropriate instance. Is there any other way to do the same?
