• Don't Understand Sql Server Error

  - by Jonathan Wood

  I have a table of users (User), and need to create a new table to track which users have referred other users. So, basically, I'm creating a many-to-many relation between rows in the same table. So I'm trying to create table UserReferrals with the columns UserId and UserReferredId. I made both columns a compound primary key. And both columns are foreign keys that link to User.UserID. Since deleting a user should also delete the relationship, I set both foreign keys to cascade deletes. When the user is deleted, any related rows in UserReferrals should also delete. But this gives me the message: 'User' table saved successfully 'UserReferrals' table Unable to create relationship 'FK_UserReferrals_User'. Introducing FOREIGN KEY constraint 'FK_UserReferrals_User' on table 'UserReferrals' may cause cycles or multiple cascade paths. Specify ON DELETE NO ACTION or ON UPDATE NO ACTION, or modify other FOREIGN KEY constraints. Could not create constraint. See previous errors. I don't get this error. A cascading delete only deletes the row with the foreign key, right? So how can it cause "cycling cascade paths"? Thanks for any tips.

• RJS error: TypeError: element is null

• Custom IIdentity and passing data from an attribute to a controller

  - by DM

  Here's my scenario: I've successfully created a custom IIdentity that I pass to a GenericPrincipal. When I access that IIdentity in my controller I have to cast the IIdentity in order to use the custom properties. example: public ActionResult Test() { MyCustomIdentity identity = (MyCustomIdentity)User.Identity; int userID = identity.UserID; ...etc... } Since I need to do this casting for nearly every action I would like to wrap this functionality in an ActionFilterAttribute. I can't do it in the controller's constructor because the context isn't initialized yet. My thought would be to have the ActionFilterAttribute populate a private property on the controller that I can use in each action method. example: public class TestController : Controller { private MyCustomIdentity identity; [CastCustomIdentity] public ActionResult() { int userID = identity.UserID; ...etc... } } Question: Is this possible and how? Is there a better solution? I've racked my brain trying to figure out how to pass public properties that are populated in an attribute to the controller and I can't get it.

• Relative Uri works for BitmapImage, but not for MediaPlayer?

  - by Thomas Stock

  This will be simple for you guys: var uri = new Uri("pack://application:,,,/LiftExperiment;component/pics/outside/elevator.jpg"); imageBitmap = new BitmapImage(); imageBitmap.BeginInit(); imageBitmap.UriSource = uri; imageBitmap.EndInit(); image.Source = imageBitmap; = Works perfectly on a .jpg with Build Action: Content Copy to Output Directory: Copy always MediaPlayer mp = new MediaPlayer(); var uri = new Uri("pack://application:,,,/LiftExperiment;component/sounds/DialingTone.wav"); mp.Open(uri); mp.Play(); = Does not work on a .wav with the same build action and copy to output. I see the file in my /debug/ folder.. MediaPlayer mp = new MediaPlayer(); var uri = new Uri(@"E:\projects\LiftExp\_solution\LiftExperiment\bin\Debug\sounds\DialingTone.wav"); mp.Open(uri); mp.Play(); = Works perfectly.. So, how do I get the sound to work with a relative path? Why is it not working this way? Let me know if you want more code or screenshots. Thanks.

• Clear form field after select for jQuery UI Autocomplete

  - by jonfhancock

  I'm developing a form, and using jQuery UI Autocomplete. When the user selects an option, I want the selection to pop into a span appended to the parent <p> tag. Then I want the field to clear rather than be populated with the selection. I have the span appearing just fine, but I can't get the field to clear. How do you cancel jQuery UI Autocomplete's default select action? Here is my code: var availableTags = ["cheese", "milk", "dairy", "meat", "vegetables", "fruit", "grains"]; $("[id^=item-tag-]").autocomplete({ source: availableTags, select: function(){ var newTag = $(this).val(); $(this).val(""); $(this).parent().append("<span>" + newTag + "<a href=\"#\">[x]</a> </span>"); } }); Simply doing $(this).val(""); doesn't work. What is maddening is that almost the exact function works fine if I ignore autocomplete, and just take action when the user types a comma as such: $('[id^=item-tag-]').keyup(function(e) { if(e.keyCode == 188) { var newTag = $(this).val().slice(0,-1); $(this).val(''); $(this).parent().append("<span>" + newTag + "<a href=\"#\">[x]</a> </span>"); } }); The real end result is to get autocomplete to work with multiple selections. If anybody has any suggestions for that, they would be welcome.

• Javascript/CSS rollover menus are patented and subject to licensing?

  - by Scott B

  Very interesting finding that a client brought to my attention today regarding javascript style rollover menus. They got a call from their legal dept that they need to change the manner in which their rollover menu is activated (at the risk of having to pay license to continue using the navigation technique). Its no April fools joke, apparently this is really happening. Apparently a company named Webvention LLC has obtained enforcement rights to a patent, U.S. Patent No. 5,251,294 - "Accessing, assembling, and using bodies of Information." A menu link, that when rolled over, expands to show a list of categorized, related links. Dropdown menus and slide-out menus are examples of this patented navigational methodology. A key component of this patent is that the dropdown/slide-out action must be initiated by a rollover or mouseover event. If the dropdown/slide-out action is initiated by any other event, such as a mouse-click event, then this behavior is not in violation of the patent. Anyone ever heard of this or know of the validity of its claims? Website is here: http://www.webventionllc.com/

  Hi, I am using JBoss4.2.2 and java6.

EJB3 in action sample code comes with ant building. I want to use Maven so I have rearranged the code some. However, I don't understan what I am doing wrong here. I have some thoughts about the jboss-app.xml file. I am not sure of how its content should look like. Grateful for any help. Best wishes Lasse

• Need assistance with Kohana 3 and catch all route turning into a 404 error

  - by alex

  Based on this documentation, I've implemented a catch all route which routes to an error page. Here is the last route in my bootstrap.php Route::set('default', '<path>', array('path' => '.+')) ->defaults(array( 'controller' => 'errors', 'action' => '404', )); However I keep getting this exception thrown when I try and go to a non existent page Kohana_Exception [ 0 ]: Required route parameter not passed: path If I make the <path> segment optional (i.e. wrap it in parenthesis) then it just seems to load the home route, which is... Route::set('home', '') ->defaults(array( 'controller' => 'home', 'action' => 'index', )); The home route is defined first. I execute my main request like so $request = Request::instance(); try { // Attempt to execute the response $request->execute(); } catch (Exception $e) { if (Kohana::$environment === Kohana::DEVELOPMENT) throw $e; // Log the error Kohana::$log->add(Kohana::ERROR, Kohana::exception_text($e)); // Create a 404 response $request->status = 404; $request->response = Request::factory(Route::get('default')->uri())->execute(); } $request->send_headers(); echo $request->response; This means that the 404 header is sent to the browser, but I assumed by sending the request to the capture all route then it should show the 404 error set up in my errors controller. <?php defined('SYSPATH') or die('No direct script access.'); class Controller_Errors extends Controller_Base { public function before() { parent::before(); } public function action_404() { $this->bodyClass[] = '404'; $this->internalView = View::factory('internal/not_found'); $longTitle = 'Page Not Found'; $this->titlePrefix = $longTitle; } } Why won't it show my 404 error page?

• How to I get the value of a custom soap header in WCF

  - by Jason Coyne

  I have created a custom soap header, and added it into my message via IClientMessageInspector public object BeforeSendRequest(ref System.ServiceModel.Channels.Message request, System.ServiceModel.IClientChannel channel) { var header = new MessageHeader<AuthHeader>(); header.Content = new AuthHeader(Key); header.Actor = "Anyone"; var header2 = header.GetUntypedHeader("Auth", "xWow"); request.Headers.Add(header2); return null; } [DataContract(Name="Auth")] public class AuthHeader { public AuthHeader(string key) { this.Key = key; } [DataMember] public string Key { get; set; } } I also have an IDispatchMessageInspector, and I can find the correct header in the list. However, there is no value. I know that the value went across the wire correctly, because the message string is correct <s:Envelope xmlns:s=\"http://schemas.xmlsoap.org/soap/envelope/\">\r\n <s:Header>\r\n <Auth s:actor=\"Anyone\" xmlns=\"xWow\" xmlns:i=\"http://www.w3.org/2001/XMLSchema-instance\">\r\n <Key xmlns=\"http://schemas.datacontract.org/2004/07/xWow.Lib\">HERE IS MY KEY VALUE!!!!</Key>\r\n </Auth>\r\n <To s:mustUnderstand=\"1\" xmlns=\"http://schemas.microsoft.com/ws/2005/05/addressing/none\">http://localhost:26443/AuthService.svc</To>\r\n <Action s:mustUnderstand=\"1\" xmlns=\"http://schemas.microsoft.com/ws/2005/05/addressing/none\">http://tempuri.org/IAuthService/GetPayload</Action>\r\n </s:Header>\r\n <s:Body>\r\n <GetPayload xmlns=\"http://tempuri.org/\" />\r\n </s:Body>\r\n</s:Envelope>" But there does not seem to be any property to retrieve this value. The MessageHeaderInfo class has Actor, etc, but nothing else useful I can find. On the client side I had to convert between Header and Untyped header, is there an equivalent operation on the server?

• ASP.NET MVC - Javascript array always passed to controller as null

  - by Xuan Vu

  I'm having some problem with passing a javascript array to the controller. I have several checkboxes on my View, when a checkbox is checked, its ID will be saved to an array and then I need to use that array in the controller. Here are the code: VIEW: var selectedSearchUsers = new Array(); $(document).ready(function () { $("#userSearch").click(function () { selectedSearchUsers.length = 0; ShowLoading(); $.ajax({ type: "POST", url: '/manage/searchusers', dataType: "json", data: $("#userSearchForm").serialize(), success: function (result) { UserSearchSuccess(result); }, cache: false, complete: function () { HideLoading(); } }); }); $(".userSearchOption").live("change", function () { var box = $(this); var id = box.attr("dataId"); var checked = box.attr("checked"); if (checked) { selectedSearchUsers.push(id); } else { selectedSearchUsers.splice(selectedSearchUsers.indexOf(id), 1); } }); $("#Send").click(function () { var postUserIDs = { values: selectedSearchUsers }; ShowLoading(); $.post("/Manage/ComposeMessage", postUserIDs, function (data) { }, "json"); }); }); When the "Send" button is clicked, I want to pass the selectedSearchUsers to the "ComposeMessage" action. Here is the Action code: public JsonResult ComposeMessage(List values) { //int count = selectedSearchUsers.Length; string count = values.Count.ToString(); return Json(count); } However, the List values is always null. Any idea why? Thank you very much.

• How to set up Hierarchical Zend Rest Routes?

  - by Kenji Baheux

  With the Zend Framework, I am trying to build routes for a REST api on resources organized in the following pattern: http://example.org/users/ http://example.org/users/234 http://example.org/users/234/items http://example.org/users/234/items/34 How do I set up this with Zend_Rest_Route? Here is how I have setup the route for the users resource (users/:id) in my bootstrap.php file: $this->bootstrap('frontController'); $frontController = Zend_Controller_Front::getInstance(); $restRoute = new Zend_Rest_Route($frontController); $frontController->getRouter()->addRoute('default', $restRoute); [As far as I understand, this is a catch all route so users/324/items/34 would results in parameters set as id=324 and items=34 and everything would be mapped to the Users (front module) Model. From there I guess I could just test for the items parameter and retrieve the item #34 for user #324 on a get request.]<=== I just checked it and it doesn't seems to work like that: Acessing /users/234/items/43 and var_dump($this->_getAllParams()); in the get action of the rest controller results in the following output: array(4) { ["controller"]=> string(5) "users" ["action"]=> string(3) "get" [2]=> string(5) "items" ["module"]=> string(7) "default"] } Somehow both ids got lost... Anyone?

• Configuring ASP.NET MVC ActionLink format with GoDaddy shared hosting

  - by Maxim Z.

  Background I have a GoDaddy shared Windows hosting plan and I'm running into a small issue with multiple domains. Many people have previously reported such an issue, but I am not interested in trying to resolve that problem altogether; all I want to accomplish is to change the format of my ActionLinks. Issue Let's say the domain that is mapped to my root hosting directory is example.com. GoDaddy forces mapping of other domains to subdirectories of the root. For example, my second domain, example1.com, is mapped to example.com/example1. I uploaded my ASP.NET MVC site to such a subdirectory, only to find that ActionLinks that are for navigation have the following format: http://example1.com/example1/Controller/Action In other words, even when I use the domain that is mapped to the subdirectory, the subdirectory is still used in the URL. However, I noticed that I can also access the same path by going to: http://example1.com/Controller/Action (leaving out the subdirectory) What I want to achieve I want to have my ActionLinks automatically drop the subdirectory, as it is not required. Is this possible without changing the ActionLinks into plain-old URLs?

• nested attributes with polymorphic has_one model

  - by Millisami

  I am using accepts_nested_attributes_for with the has_one polymorphic model in rails 2.3.5 Following are the models and its associations: class Address < ActiveRecord::Base attr_accessible :city, :address1, :address2 belongs_to :addressable, :polymorphic => true validates_presence_of :address1, :address2, :city end class Vendor < ActiveRecord::Base attr_accessible :name, :address_attributes has_one :address, :as => :addressable, :dependent => :destroy accepts_nested_attributes_for :address end This is the view: - form_for @vendor do |f| = f.error_messages %p = f.label :name %br = f.text_field :name - f.fields_for :address_attributes do |address| = render "shared/address_fields", :f => address %p = f.submit "Create" This is the partial shared/address_fields.html.haml %p = f.label :city %br= f.text_field :city %span City/Town name like Dharan, Butwal, Kathmandu, .. %p = f.label :address1 %br= f.text_field :address1 %span City Street name like Lazimpat, New Road, .. %p = f.label :address2 %br= f.text_field :address2 %span Tole, Marg, Chowk name like Pokhrel Tole, Shanti Marg, Pako, .. And this is the controller: class VendorsController < ApplicationController def new @vendor = Vendor.new end def create @vendor = Vendor.new(params[:vendor]) if @vendor.save flash[:notice] = "Vendor created successfully!" redirect_to @vendor else render :action => 'new' end end end The problem is when I fill in all the fileds, the record gets save on both tables as expected. But when I just the name and city or address1 filed, the validation works, error message shown, but the value I put in the city or address1, is not persisted or not displayed inside the address form fields? This is the same case with edit action too. Though the record is saved, the address doesn't show up on the edit form. Only the name of the Client model is shown. Actually, when I look at the log, the address model SQL is not queried even at all.

• Using complex data types from Java in Axis webservice

  - by Manuel Ferreria

  I am currently developing a Java app which handles a SOAP webservice. The problem lies after I parse the WSDL [the Parser object from Apache Axis does it for me], and I create the call. When I try to invoke it, I have to pass a Object[] to assign the parameters [taken from the Action of the WSDL]. A normal action is easy, but when I have custom datatypes, I can't get it to fill it out for me. I try to pass Object[]{ new Object { }}, but it assigns the first field instead. I can't pass it already processed, because it changes the '< ' to '--lt --gt', and the server doesn't recognize it'. This is a fragment of the WSDL. <s:element name="FERecuperaQTYRequest"> <s:complexType> <s:sequence> <s:element minOccurs="0" maxOccurs="1" name="argAuth" type="tns:FEAuthRequest" /> </s:sequence> </s:complexType> </s:element> <s:complexType name="FEAuthRequest"> <s:sequence> <s:element minOccurs="0" maxOccurs="1" name="Token" type="s:string" /> <s:element minOccurs="0" maxOccurs="1" name="Sign" type="s:string" /> <s:element minOccurs="1" maxOccurs="1" name="cuit" type="s:long" /> </s:sequence> </s:complexType> And this is the troublesome Java Fragment QTY = (String) call.invoke ( new Object[]{ new Object[]{ tokenConexion.getToken (), tokenConexion.getSign (), tokenConexion.getCUIT () } });

• Best Practice for Shell Layout and Switching Views - Prism, SL4, On Demand Load Modules

  - by kmacmahon

  I am learning Prism, and I have a question on the best approach for the main Shell. Assuming the Shell has 2 regions: Toolbar, Main. The toolbar has 3 main buttons that each represent a different On Demand Load Module. Each of these modules currently register themselves as fitting in the Main Region. When I click one of the buttons I want to do the following: Notify any active view that its switching, with an option to cancel if there is a pending action still required. This might cascade to child views. If the action isn't cancelled then load the on demand module if it has not yet been loaded, else activate it within the region. Should these three modules all fit in the same Region or should my shell have 3 regions defined within content presenters? One of the areas I got stuck on was that when you register a view from the Module Initialize, it doesn't get added with a strongly typed name, so when I tried to determine if my view was already added to the region with GetView(viewname) it always returns null, so I end up adding another view to the region.

• This 404 seems unavoidable - what am I doing wrong? [Ninject 2.0 with ASP.NET MVC 2 on .NET 4]

  I downloaded the fairly new Ninject 2.0 and Ninject.Web.Mvc (targeting mvc2) sources today, and successfully built them against .NET 4 (release configuration). When trying to run an application using Ninject 2.0, i keep getting 404 errors and I can't figure out why. This is my global.asax.cs (slightly shortified, for brevity): using ... using Ninject; using Ninject.Web.Mvc; using Ninject.Modules; namespace Booking.Web { public class MvcApplication : NinjectHttpApplication { protected override void OnApplicationStarted() { Booking.Models.AutoMapperBootstrapper.Initialize(); RegisterAllControllersIn(Assembly.GetExecutingAssembly()); base.OnApplicationStarted(); } protected void RegisterRoutes(RouteCollection routes) { ... routes.MapRoute( "Default", "{controller}/{action}/{id}", new { controller = "Entry", action = "Index", id = "" } ); } protected override IKernel CreateKernel() { INinjectModule[] mods = new INinjectModule[] {...}; return new StandardKernel(mods); } } } The EntryController exists, and has an Index method that simply does a return View(). I have debugged, and verified that the call to RegisterAllControllersIn() is executed. I have also tried to use Phil Haacks Routing debugger but I still get a 404. What do I do to find the cause of this?

• Asp.net MVC 2, MvcContrib, and a base controller with redirect actions

  - by jeriley

  I've got a base controller that takes a couple generics, nothing overly fancy. public class SystemBaseController<TForm, TFormViewModel> : Controller where TForm : class, IForm where TFormViewModel : class, IViewModel ok, no big deal. I have a method "CompleteForm" that takes in the viewModel, looks kinda like this ... public ActionResult CompleteForm(TFormViewModel viewModel) { //does some stuff return this.RedirectToAction(c => c.FormInfo(viewModel)); } Problem is, the controller that inherits this, like so public class SalesFormController : SystemBaseController<SalesForm, SalesViewModel> { } I end up getting a error from MvcContrib - Controller name must end in 'Controller' at this point ... public RedirectToRouteResult(Expression<Action<T>> expression) : this(expression, expr => Microsoft.Web.Mvc.Internal.ExpressionHelper.GetRouteValuesFromExpression(expr)) {} The expression that's passed in is correct (SystemBaseController blahblah) but I'm not sure why its 1.) saying there's no controller at the end, and 2.) if I pull out everything into the controller (out of the base), works just fine. Do I need to write or setup some kind of action filter of my own or what am I missing?

• Grails - Simple hasMany Problem - How does 'save' work?

  - by gav

  My problem is this: I want to create a grails domain instance, defining the 'Many' instances of another domain that it has. I have the actual source in a Google Code Project but the following should illustrate the problem. class Person { String name static hasMany[skills:Skill] static constraints = { id (visible:false) skills (nullable:false, blank:false) } } class Skill { String name String description static constraints = { id (visible:false) name (nullable:false, blank:false) description (nullable:false, blank:false) } } If you use this model and def scaffold for the two Controllers then you end up with a form like this that doesn't work; My own attempt to get this to work enumerates the Skills as checkboxes and looks like this; But when I save the Volunteer the skills are null! This is the code for my save method; def save = { log.info "Saving: " + params.toString() def skills = params.skills log.info "Skills: " + skills def volunteerInstance = new Volunteer(params) log.info volunteerInstance if (volunteerInstance.save(flush: true)) { flash.message = "${message(code: 'default.created.message', args: [message(code: 'volunteer.label', default: 'Volunteer'), volunteerInstance.id])}" redirect(action: "show", id: volunteerInstance.id) log.info volunteerInstance } else { render(view: "create", model: [volunteerInstance: volunteerInstance]) } } This is my log output (I have custom toString() methods); 2010-05-10 21:06:41,494 [http-8080-3] INFO bumbumtrain.VolunteerController - Saving: ["skills":["1", "2"], "name":"Ian", "_skills":["", ""], "create":"Create", "action":"save", "controller":"volunteer"] 2010-05-10 21:06:41,495 [http-8080-3] INFO bumbumtrain.VolunteerController - Skills: [1, 2] 2010-05-10 21:06:41,508 [http-8080-3] INFO bumbumtrain.VolunteerController - Volunteer[ id: null | Name: Ian | Skills [Skill[ id: 1 | Name: Carpenter ] , Skill[ id: 2 | Name: Sound Engineer ] ]] Note that in the final log line the right Skills have been picked up and are part of the object instance. When the volunteer is saved the 'Skills' are ignored and not commited to the database despite the in memory version created clearly does have the items. Is it not possible to pass the Skills at construction time? There must be a way round this? I need a single form to allow a person to register but I want to normalise the data so that I can add more skills at a later time. If you think this should 'just work' then a link to a working example would be great. Hope this makes sense, thanks in advance! Gav
