  • How to stop Django from adding extra html elements to rendered widgets.

    - by stinkypyper
    I have a Django radio button group that renders to HTML as follows: <ul> <li><label for="id_package_id_0"><input type="radio" id="id_package_id_0" value="1" name="package_id" /> Test 256</label></li> <li><label for="id_package_id_1"><input type="radio" id="id_package_id_1" value="2" name="package_id" /> Test 384</label></li> <li><label for="id_package_id_2"><input type="radio" id="id_package_id_2" value="3" name="package_id" /> Test 512</label></li> <li><label for="id_package_id_3"><input type="radio" id="id_package_id_3" value="4" name="package_id" /> Test 768</label></li> <li><label for="id_package_id_4"><input type="radio" id="id_package_id_4" value="5" name="package_id" /> Test 1024</label></li> </ul> I need it to render without being a list. I am a aware of form.as_p, form.as_table, and form.as_ul. They will not help me as they continue to add extra HTML tags. As well, I am not using the form object in it's absolute entirety, just for validation. I am doing a custom template for the form already, but wish to continue to the radio widget.

  • Can I create an xml that specifies element from 2 nested xsd's without using a prefixes?

    - by TweeZz
    I have 2 xsd's which are nested: DefaultSchema.xsd: <?xml version="1.0" encoding="utf-8"?> <xs:schema id="DefaultSchema" targetNamespace="http://myNamespace.com/DefaultSchema.xsd" elementFormDefault="qualified" xmlns="http://myNamespace.com/DefaultSchema.xsd" xmlns:xs="http://www.w3.org/2001/XMLSchema" > <xs:complexType name="ZForm"> <xs:sequence minOccurs="0" maxOccurs="unbounded"> <xs:element name="Part" minOccurs="0" maxOccurs="unbounded" type="Part"/> </xs:sequence> <xs:attribute name="Title" use="required" type="xs:string"/> <xs:attribute name="Version" type="xs:int"/> </xs:complexType> <xs:complexType name="Part"> <xs:sequence minOccurs="0" maxOccurs="unbounded"> <xs:element name="Label" type="Label" minOccurs="0"></xs:element> </xs:sequence> <xs:attribute name="Title" use="required" type="xs:string"/> </xs:complexType> <xs:complexType name="Label"> <xs:simpleContent> <xs:extension base="xs:string"> <xs:attribute name="Title" type="xs:string"/> </xs:extension> </xs:simpleContent> </xs:complexType> </xs:schema> ExportSchema.xsd: (this one kinda wraps 1 more element (ZForms) around the main element (ZForm) of the DefaultSchema) <?xml version="1.0" encoding="utf-8"?> <xs:schema id="ExportSchema" targetNamespace="http://myNamespace.com/ExportSchema.xsd" elementFormDefault="qualified" xmlns="http://myNamespace.com/DefaultSchema.xsd" xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:es="http://myNamespace.com/ExportSchema.xsd" > <xs:import namespace="http://myNamespace.com/DefaultSchema.xsd" schemaLocation="DefaultSchema.xsd"/> <xs:element name="ZForms" type="es:ZFormType"></xs:element> <xs:complexType name="ZFormType"> <xs:sequence> <xs:element name="ZForm" type="ZForm" maxOccurs="unbounded" /> </xs:sequence> </xs:complexType> </xs:schema> And then finally I have a generated xml: <?xml version="1.0" encoding="utf-8"?> <ZForms xmlns="http://myNamespace.com/ExportSchema.xsd"> <ZForm Version="1" Title="FormTitle"> <Part Title="PartTitle" > <Label Title="LabelTitle" /> </Part> </ZForm> </ZForms> Visual studio complains it doesn't know what 'Part' is. I was hoping I do not need to use xml namespace prefixes (..) to make this xml validate, since ExportSchema.xsd has a reference to the DefaultSChema.xsd. Is there any way to make that xml structure valid without explicitly specifying the DefaultSchema.xsd? Or is this a no go?

  • Why does the Ternary\Conditional operator seem significantly faster

    - by Jodrell
    Following on from this question, which I have partially answered. I compile this console app in x64 Release Mode, with optimizations on, and run it from the command line without a debugger attached. using System; using System.Diagnostics; class Program { static void Main() { var stopwatch = new Stopwatch(); var ternary = Looper(10, Ternary); var normal = Looper(10, Normal); if (ternary != normal) { throw new Exception(); } stopwatch.Start(); ternary = Looper(10000000, Ternary); stopWatch.Stop(); Console.WriteLine( "Ternary took {0}ms", stopwatch.ElapsedMilliseconds); stopwatch.Start(); normal = Looper(10000000, Normal); stopWatch.Stop(); Console.WriteLine( "Normal took {0}ms", stopwatch.ElapsedMilliseconds); if (ternary != normal) { throw new Exception(); } Console.ReadKey(); } static int Looper(int iterations, Func<bool, int, int> operation) { var result = 0; for (int i = 0; i < iterations; i++) { var condition = result % 11 == 4; var value = ((i * 11) / 3) % 5; result = operation(condition, value); } return result; } static int Ternary(bool condition, in value) { return value + (condition ? 2 : 1); } static int Normal(int iterations) { if (condition) { return = 2 + value; } return = 1 + value; } } I don't get any exceptions and the output to the console is somthing close to, Ternary took 107ms Normal took 230ms When I break down the CIL for the two logical functions I get this, ... Ternary ... { : ldarg.1 // push second arg : ldarg.0 // push first arg : brtrue.s T // if first arg is true jump to T : ldc.i4.1 // push int32(1) : br.s F // jump to F T: ldc.i4.2 // push int32(2) F: add // add either 1 or 2 to second arg : ret // return result } ... Normal ... { : ldarg.0 // push first arg : brfalse.s F // if first arg is false jump to F : ldc.i4.2 // push int32(2) : ldarg.1 // push second arg : add // add second arg to 2 : ret // return result F: ldc.i4.1 // push int32(1) : ldarg.1 // push second arg : add // add second arg to 1 : ret // return result } Whilst the Ternary CIL is a little shorter, it seems to me that the execution path through the CIL for either function takes 3 loads and 1 or 2 jumps and a return. Why does the Ternary function appear to be twice as fast. I underdtand that, in practice, they are both very quick and indeed, quich enough but, I would like to understand the discrepancy.

  • SQL Server 2008 Stored Proc suddenly returns -1

    - by aaginor
    I use the following stored procedure from my SQL Server 2008 database to return a value to my C#-Program ALTER PROCEDURE [dbo].[getArticleBelongsToCatsCount] @id int AS BEGIN SET NOCOUNT ON; DECLARE @result int; set @result = (SELECT COUNT(*) FROM art_in_cat WHERE child_id = @id); return @result; END I use a SQLCommand-Object to call this Stored Procedure public int ExecuteNonQuery() { try { return _command.ExecuteNonQuery(); } catch (Exception e) { Logger.instance.ErrorRoutine(e, "Text: " + _command.CommandText); return -1; } } Till recently, everything works fine. All of a sudden, the stored procedure returned -1. At first, I suspected, that the ExecuteNonQuery-Command would have caused and Exception, but when stepping through the function, it shows that no Exception is thrown and the return value comes directly from return _command.ExecuteNonQuery(); I checked following parameters and they were as expected: - Connection object was set to the correct database with correct access values - the parameter for the SP was there and contained the right type, direction and value Then I checked the SP via SQLManager, I used the same value for the parameter like the one for which my C# brings -1 as result (btw. I checked some more parameter values in my C' program and they ALL returned -1) but in the manager, the SP returns the correct value. It looks like the call from my C# prog is somehow bugged, but as I don't get any error (it's just the -1 from the SP), I have no idea, where to look for a solution.

  • jQuery - Form input return confirm to delete

    - by bruno
    hello guys. I struggled a lot before posting here :) now, I want to replace my default javascript confirmation for deleting a file. I saw a lot of examples here, but no example with form input. Now I have his form: <form action="delete.php" method="post"> <input type="hidden" name="id" value="<{$pid}>" /> <input type="hidden" name="picture" value="<{$lang_del_pic}>" /> <input type="image" src="<{xoImgUrl}>img/del-icon.gif" width="16" height="16" align="bottom" border="0" alt="Delete media" name="pictured" value="<{$lang_del_pic}>" onclick="javascript: return confirm('<{$lang_confirm_del}>');" /> </form> Now, I did everything, I have this div: <div id="dialog-confirm" title="Empty the recycle bin?"> <p><span class="ui-icon ui-icon-alert" style="float:left; margin:0 7px 20px 0;"></span>These items will be permanently deleted and cannot be recovered. Are you sure?</p> </div> this javascript: <script type="text/javascript"> $(document).ready(function() { $("#dialog").dialog({ autoOpen: false, modal: true }); }); $(".confirmLink").click(function(e) { e.preventDefault(); var targetUrl = $(this).attr("href"); $("#dialog").dialog({ buttons : { "Confirm" : function() { window.location.href = targetUrl; }, "Cancel" : function() { $(this).dialog("close"); } } }); $("#dialog").dialog("open"); }); </script> and this new form: <form name="dialog-confirm" id="dialog-confirm" method="post"> <input type="hidden" name="id" value="<{$pid}>" /> <input type="hidden" name="picture" value="<{$lang_del_pic}>" /> <input type="image" src="<{xoImgUrl}>img/del-icon.gif" width="16" height="16" align="bottom" border="0" alt="Delete media" name="pictured" value="" id="opener" /> </form> On press, I call successfuly the jQuery modal diolog, and everything works, but somehow, when I press 'delete all' the script tells me - "the script is called without the necessary parameters" Now I guess I am failig to send the pic ID to be deleted with the jQuery, .. but do not know how to fix it. Any ideas ?

  • Python finding substring between certain characters using regex and replace()

    - by jCuga
    Suppose I have a string with lots of random stuff in it like the following: strJunk ="asdf2adsf29Value=five&lakl23ljk43asdldl" And I'm interested in obtaining the substring sitting between 'Value=' and '&', which in this example would be 'five'. I can use a regex like the following: match = re.search(r'Value=?([^&>]+)', strJunk) >>> print match.group(0) Value=five >>> print match.group(1) five How come match.group(0) is the whole thing 'Value=five' and group(1) is just 'five'? And is there a way for me to just get 'five' as the only result? (This question stems from me only having a tenuous grasp of regex) I am also going to have to make a substitution in this string such such as the following: val1 = match.group(1) strJunk.replace(val1, "six", 1) Which yields: 'asdf2adsf29Value=six&lakl23ljk43asdldl' Considering that I plan on performing the above two tasks (finding the string between 'Value=' and '&', as well as replacing that value) over and over, I was wondering if there are any other more efficient ways of looking for the substring and replacing it in the original string. I'm fine sticking with what I've got but I just want to make sure that I'm not taking up more time than I have to be if better methods are out there.

  • Why wouldn't an embedded silverlight control work in a page?

    - by rsteckly
    Hi, I have a silverlight application project in my solution. The other project is a web application project that has a .xap file in ClientBin. When I created the silverlight project, it asked if I wanted the asp.net application to host it (and I said yes). In the root directory, there is a test page for the silverlight control. That loads the control. In another directory, I insert the SAME asp markup to get the silverlight control to launch again. Nothing happens. Why would the silverlight launch on one page and not on the other? Can people help point me to documentation about dependencies that I might not know about? I've put a reference to Silverlight.js on the page as well. Here's the markup: <div id="silverlightControlHost"> <object data="data:application/x-silverlight-2," type="application/x-silverlight-2" width="100%" height="100%"> <param name="source" value="../ClientBin/Editor.xap"/> <param name="onError" value="onSilverlightError" /> <param name="background" value="white" /> <param name="minRuntimeVersion" value="3.0.40818.0" /> <param name="autoUpgrade" value="true" /> <a href="http://go.microsoft.com/fwlink/?LinkID=149156&v=3.0.40818.0" style="text-decoration:none"> <img src="http://go.microsoft.com/fwlink/?LinkId=108181" alt="Get Microsoft Silverlight" style="border-style:none"/> </a> </object><iframe id="_sl_historyFrame" style="visibility:hidden;height:0px;width:0px;border:0px"></iframe></div> </div>

  • What is the best way to set default values in ActiveRecord?

    - by ryw
    What is the best way to set default value in ActiveRecord? I see a post from Pratik that describes an ugly, complicated chunk of code: http://m.onkey.org/2007/7/24/how-to-set-default-values-in-your-model class Item < ActiveRecord::Base def initialize_with_defaults(attrs = nil, &block) initialize_without_defaults(attrs) do setter = lambda { |key, value| self.send("#{key.to_s}=", value) unless !attrs.nil? && attrs.keys.map(&:to_s).include?(key.to_s) } setter.call('scheduler_type', 'hotseat') yield self if block_given? end end alias_method_chain :initialize, :defaults end YUCK! I have seen the following examples googling around: def initialize super self.status = ACTIVE unless self.status end and def after_initialize return unless new_record? self.status = ACTIVE end I've also seen people put it in their migration, but I'd rather see it defined in the model code. What's the best way to set default value for fields in ActiveRecord model?

  • Accommodating null values in a list?

    - by h259bws
    Hi, I'm new to Java and Groovy and am running into trouble with the following Groovy script. I created this whittled down version of a larger script to facilitate debugging. The script is iterating through a list trying to calc a running total of the values of all objects in the list. Some or all of these objects' values may be null. Script import org.apache.commons.lang.math.NumberUtils class Field { def name def value } def fields = [ new Field(name:'Annuities %', value:75), new Field(name:'Other %', value:null), ] //def totalFunding = fields.inject(0) {int total, Field myField - // total + NumberUtils.toInt(myField.value,0) as Integer def totalFunding = fields.inject(0) {int total, Field myField - total + myField?.value as Integer } It gets this error: Exception thrown: java.lang.NullPointerException java.lang.NullPointerException at Script3$_run_closure1.doCall(Script3:15) at Script3.run(Script3:14) What is the correct way to accomodate null values?

    I'm learning PHP right now and I'm trying to insert data into a MySQL database called "pumpl2" The table is set up like this. create table product ( productid int unsigned not null auto_increment primary key, price int(9) not null, value int(9) not null, description text ); I have a form and want to insert the fields from the form in the database. Here is what the php file looks like. <?php // create short variable names $price = $_POST['price']; $value = $_POST['value']; $description = $_POST['description']; if (!$price || !$value || !$description) { echo "You have not entered all the required details.<br />" ."Please go back and try again."; exit; } @ $db = new mysqli('localhost', 'pumpl', '********', 'pumpl2'); if (mysqli_connect_errno()) { echo "Error: Could not connect to database. Please try again later."; exit; } $query = "insert into pumpl2 values ('".$price."', '".$value."', '".$description."')"; $result = $db->query($query); if ($result) { echo $db->affected_rows." product inserted into database."; } else { echo "An error has occurred. The item was not added."; } $db->close(); ?> When I submit the form, I get an error message "An error has occurred. The item was not added." Does anyone know what the problem is? Thank you!

  • jQuery Ajax loads URL multiple times, how do I unbind/rebind properly?

    - by gmoz22
    I load a SELECT element via Ajax (list of brands), get its selected value (brand id) and load another SELECT via another Ajax URL (list of templates for currently selected brand). Here's my code: $(document).ready( function() { // DO NOT cache Ajax calls $.ajaxSetup ({ cache: false }); // loader var ajax_load = "Loading..."; // Brands List URL var loadBrandUrl = "getBrandsList.php"; // Templates List URL var loadTemplateUrl = "getTemplatesList.php"; $("#brandslistSelect").html(ajax_load).load(loadBrandUrl) .ajaxComplete(function(){ // Brands select loaded /* Load Templates SELECT the first time since no .change() has happened */ var selectedBrand = $("#brandslistSelect option:selected").attr("value"); // get the value console.log(selectedBrand); // Log selected brand to console // get Templates select, commented for now since it does an infinite loop // $("#templateslistSelect").html(ajax_load).load(loadTemplateUrl, { BrandId: selectedBrand } ); /* End initial load template */ /* On interaction with the Brands SELECT */ $("#brandslistSelect").change(function () { // on interaction with select selectedBrand = $("#brandslistSelect option:selected").attr("value"); // get the value // get Templates SELECT $("#templateslistSelect").html(ajax_load).load(loadTemplateUrl, { BrandId: selectedBrand } ) }); /* End interaction with the Brands SELECT */ }); }); It returns selectedBrand in the console 3 times : selectedBrand = undefined selectedBrand = undefined selectedBrand = 101 Now, if I uncomment the following line, same output as above but it also loads the templates URL indefinitely : // $("#templateslistSelect").html(ajax_load).load(loadTemplateUrl, { BrandId: selectedBrand } ); Any idea how I could modify this code to make it work as intended? Thanks for your help stackOverflow community!

  • Setting Session/Cookie via ajax request made on other website

    - by user596805
    Hi, That's my problem: I have an website, example.com, in which index.html file a introduced a <script src="website.net/js.js"></script> You can see, that this is on other web server. In the js.js I have some data that I want to send to php. For that, I am using Ajax. So, I made a request to "website.net/data.php" using method get. In data.php file everything is ok,I received the value, but I want to set a cookie which value is what I received through ajax. Here is the problem. The setcookie function says that the cookie was set, but when I check in the browser, there's no cookie! It works fine if the index.html file where I use <script src="website.net/js.js"></script> is hosted on the same domain where I am making the request. If it is on another domain, it doesn't work anymore. I have read something about Ajax cross site, but I don't want to send something back to example.com. All I want is to send some data from example.com to website.net and then setting a cookie based on that value. Thank you very much, and sorry for my English! Later edit: I am not used with this website. From the example.net I take a single value. On website.net I receive that value, I check if it's not already a cookie set, if it's not, I set it. On the same page, website.net, I use this cookie too.

  • Creating a custom module for Orchard

    - by Moran Monovich
    I created a custom module using this guide from Orchard documentation, but for some reason I can't see the fields in the content type when I want to create a new one. this is my model: public class CustomerPartRecord : ContentPartRecord { public virtual string FirstName { get; set; } public virtual string LastName { get; set; } public virtual int PhoneNumber { get; set; } public virtual string Address { get; set; } public virtual string Profession { get; set; } public virtual string ProDescription { get; set; } public virtual int Hours { get; set; } } public class CustomerPart : ContentPart<CustomerPartRecord> { [Required(ErrorMessage="you must enter your first name")] [StringLength(200)] public string FirstName { get { return Record.FirstName; } set { Record.FirstName = value; } } [Required(ErrorMessage = "you must enter your last name")] [StringLength(200)] public string LastName { get { return Record.LastName; } set { Record.LastName = value; } } [Required(ErrorMessage = "you must enter your phone number")] [DataType(DataType.PhoneNumber)] public int PhoneNumber { get { return Record.PhoneNumber; } set { Record.PhoneNumber = value; } } [StringLength(200)] public string Address { get { return Record.Address; } set { Record.Address = value; } } [Required(ErrorMessage = "you must enter your profession")] [StringLength(200)] public string Profession { get { return Record.Profession; } set { Record.Profession = value; } } [StringLength(500)] public string ProDescription { get { return Record.ProDescription; } set { Record.ProDescription = value; } } [Required(ErrorMessage = "you must enter your hours")] public int Hours { get { return Record.Hours; } set { Record.Hours = value; } } } this is the Handler: class CustomerHandler : ContentHandler { public CustomerHandler(IRepository<CustomerPartRecord> repository) { Filters.Add(StorageFilter.For(repository)); } } the Driver: class CustomerDriver : ContentPartDriver<CustomerPart> { protected override DriverResult Display(CustomerPart part, string displayType, dynamic shapeHelper) { return ContentShape("Parts_Customer", () => shapeHelper.Parts_BankCustomer( FirstName: part.FirstName, LastName: part.LastName, PhoneNumber: part.PhoneNumber, Address: part.Address, Profession: part.Profession, ProDescription: part.ProDescription, Hours: part.Hours)); } //GET protected override DriverResult Editor(CustomerPart part, dynamic shapeHelper) { return ContentShape("Parts_Customer", () => shapeHelper.EditorTemplate( TemplateName:"Parts/Customer", Model: part, Prefix: Prefix)); } //POST protected override DriverResult Editor(CustomerPart part, IUpdateModel updater, dynamic shapeHelper) { updater.TryUpdateModel(part, Prefix, null, null); return Editor(part, shapeHelper); } the migration: public class Migrations : DataMigrationImpl { public int Create() { // Creating table CustomerPartRecord SchemaBuilder.CreateTable("CustomerPartRecord", table => table .ContentPartRecord() .Column("FirstName", DbType.String) .Column("LastName", DbType.String) .Column("PhoneNumber", DbType.Int32) .Column("Address", DbType.String) .Column("Profession", DbType.String) .Column("ProDescription", DbType.String) .Column("Hours", DbType.Int32) ); return 1; } public int UpdateFrom1() { ContentDefinitionManager.AlterPartDefinition("CustomerPart", builder => builder.Attachable()); return 2; } public int UpdateFrom2() { ContentDefinitionManager.AlterTypeDefinition("Customer", cfg => cfg .WithPart("CommonPart") .WithPart("RoutePart") .WithPart("BodyPart") .WithPart("CustomerPart") .WithPart("CommentsPart") .WithPart("TagsPart") .WithPart("LocalizationPart") .Creatable() .Indexed()); return 3; } } Can someone please tell me if I am missing something?

  • Why is the Objective-C Boolean data type defined as a signed char?

    - by EddieCatflap
    Something that has piqued my interest is Objective-C's BOOL type definition. Why is it defined as a signed char (which could cause unexpected behaviour if a value greater than 1 byte in length is assigned to it) rather than as an int, as C does (much less margin for error: a zero value is false, a non-zero value is true)? The only reason I can think of is the Objective-C designers micro-optimising storage because the char will use less memory than the int. Please can someone enlighten me?

  • DefaultTableCellRenderer getTableCellRendererComponent never gets called

    - by Dean Schulze
    I need to render a java.util.Date in a JTable. I've implemented a custom renderer that extends DefaultTableCellRenderer (below). I've set it as the renderer for the column, but the method getTableCellRendererComponent() never gets called. This is a pretty common problem, but none of the solutions I've seen work. public class DateCellRenderer extends DefaultTableCellRenderer { String sdfStr = "yyyy-MM-dd HH:mm:ss.SSS"; SimpleDateFormat sdf = new SimpleDateFormat(sdfStr); public Component getTableCellRendererComponent(JTable table, Object value, boolean isSelected, boolean hasFocus, int row, int column) { super.getTableCellRendererComponent(table, value, isSelected, hasFocus, row, column); if (value instanceof Date) { this.setText(sdf.format((Date) value)); } else logger.info("class: " + value.getClass().getCanonicalName()); return this; } } I've installed the custom renderer (and verified that it has been installed) like this: DateCellRenderer dcr = new DateCellRenderer(); table.getColumnModel().getColumn(2).setCellRenderer(dcr); I've also tried table.setDefaultRenderer( java.util.Date.class, dcr ); Any idea why the renderer gets installed, but never called?

  • XSLT Similar functionality to SQL "WHERE LIKE"

    - by Fishcake
    I have the following XML <Answer> <Label>FCVCMileage</Label> <Value>3258</Value> <Iteration>0</Iteration> <DataType>NUMBER</DataType> </Answer> And need to get the Value underneath the Mileage label. However the 4 letter prefix to Mileage could be any 1 of 8 different prefixes. I know I could find the value by testing for every combination using xsl:if or xsl:choose but is there a more elegant way that would work similar to the following SQL and also wouldn't need changes to code being made if other prefixes were added. WHERE label LIKE '%Mileage' NB. There will only ever be 1 label element containing the word Mileage Cheers!

  • Lookup function not working (RS SP2)

    - by Al Reyes
    Hi, I made the upgrade to SP2. I'm trying to use the Lookup function to link data from two different servers. I'm trying first a simple exercise linking data from two datasets from the same server, having one dataset with journals and the other with the account description. My Expression looks like this at a field on the table I have: =Lookup(Fields!ACTINDX.Value,Fields!ACTINDX.Value,Fields!ACTDESCR.Value,"ACCTINFO") I made sure of the names and using only uppercases for datasets and fields but I'm receiving the following message when I try to preview: "An error occurred during local report processing. The definition of the report '/DETAIL' is invalid. The Value expression for the text box 'ACTINDX' refers to the field 'ACTDESCR'. Report item expressions can only refer to fields within the current dataset scope or, if inside an aggregate, the specified dataset scope". I'll appreciate any suggestions. Regards, Al
