  • Help dealing with data dependency between two registration forms

    - by franko75
    I have a tricky issue here with a registration of both a user and his/her pet. Both the user and the pet are treated as separate entities and both require separate registration forms. However, the user's pet has to be linked to the user via a foreign key in the database. The process is basically that when a new user joins the site, firstly they register their pet, then they register themselves. The reason for this order is to check their pet's eligibility for the site (there are some criteria to be met) first, instead of getting the user to sign up only to then find out their pet is ineligible. It is this ordering of the form submissions which is causing me a bit of a headache, as follows... The site is being developed with an MVC framework, and the User registration process is managed via a method in a User_form controller, while the pet registration process is managed via a method in the Pet_form controller. The pet registration form happens first, and the pet data can be saved without the owner_id at this stage, with the user id possibly being added (e.g by retrieving pet's id from session) following user registration. However, doing it this way could potentially result in redundant data, where pet records would be created in the database, but if the user doesn't actually register themselves too, then the pets will be ownerless records in the DB. Other option is to serialize the new pet's data at the pet registration stage, don't save it to the DB until the user fills out their registration form. Once the user is created, i can pass serialised data AND the owner_id to a method in the Pet Model which can update the DB. However, I also need to set the newly created $pet to $this-pet which I then access for a sequence of other related forms. Should I just set the session variable in the model method? Then in the Pet controller constructor, do a check for pet stored in session, if yes, assign to $this-pet... If this makes any sense to anybody and you have some advice, i'd be grateful to hear it!

  • Can Spring understand @Inject replacing Weld as a JSR-299 implementation?

    - by Thorbjørn Ravn Andersen
    I have noticed from several web pages that apparently Spring 3.0 supports @Inject from JSR-330. As we would really like to use JSR-299 syntax for dependency injection in our libraries for both web apps and stand-alone applications, and have alternatives to Weld, it would be nice if Spring could do this. Being a novice to Spring, I tried downloading the Spring Framework distribution and put all jars on the Eclipse build path. No Inject annotation so my existing test project using Weld did not compile. Can this be done with Spring? What do I need to do to get it running? (I am aware that Guice eventually will support this too. It is only in SVN for now, and if there is an official Spring release which can, that would be better.)

  • C++/CLI Missing MSVCR90.DLL

    - by Mitch
    I have a c++/cli dll that I load at runtime and which works great in debug mode. If I try and load the dll in release mode it fails to load stating that one or more dependencies are missing. If I run depends against it I am missing MSVCR90.DLL from MSVCM90.DLL. If I check the debug version of the dll it also has the missing dependency, but against the debug (D) version. I have made sure debug/release embed the manifest file. I read something about there being issues with the app loading the dll being build as Any CPU and the dll being built as x86, but I don't see how to set them both to x86. I am using VS2010. Anyway, I've been messing around for a while now and have no idea what is wrong. I'm sure someone out there knows what is going on. Let me know if I need to include additional info.

  • Unit Testing: hard dependency MessageBox.Show()

    - by Sean B
    What ways can the SampleConfirmationDialog be unit tested? The SampleConfirmationDialog would be exercised via acceptance tests, however how could we unit test it, seeing as MessageBox is not abstract and no matching interface? public interface IConfirmationDialog { /// <summary> /// Confirms the dialog with the user /// </summary> /// <returns>True if confirmed, false if not, null if cancelled</returns> bool? Confirm(); } /// <summary> /// Implementation of a confirmation dialog /// </summary> public class SampleConfirmationDialog : IConfirmationDialog { /// <summary> /// Confirms the dialog with the user /// </summary> /// <returns>True if confirmed, false if not, null if cancelled</returns> public bool? Confirm() { return MessageBox.Show("do operation x?", "title", MessageBoxButton.YesNo, MessageBoxImage.Question) == MessageBoxResult.Yes; } }

  • Hidden Features of Google Guice

    - by Jon
    Google Guice provides some great dependency injection features. I came across the @Nullable feature recently which allows you to mark constructor arguments as optional (permitting null) since Guice does not permit these by default: e.g. public Person(String firstName, String lastName, @Nullable Phone phone) { this.firstName = checkNotNull(firstName, "firstName"); this.lastName = checkNotNull(lastName, "lastName"); this.phone = phone; } http://code.google.com/p/google-guice/wiki/UseNullable What are the other useful features of Guice (particularly the less obvious ones) that people use?

  • How do I set up Array/List dependencies in code with Castle Windsor?

    - by SharePoint Newbie
    Hi, I have the following classes: class Repository : IRepository class ReadOnlyRepository : Repository abstract class Command abstract CommandImpl : Command { public CommandImpl(Repository repository){} } class Service { public Service (Command[] commands){} } I register them in code as follows: var container = new Container("WindsorCOntainer.config"); var container = new WindsorContainer(new XmlInterpreter("WindsorConfig.xml")); container.Kernel.Resolver.AddSubResolver(new ArrayResolver(container.Kernel)); container.AddComponent("repository", typeof(RentServiceRepository)); container.Resolve<RentServiceRepository>(); container.AddComponent("command", typeof(COmmandImpl)); container.AddComponent("rentService", typeof (RentService)); container.Resolve<RentService>(); // Fails here I get the message that "RentService is waiting for dependency commands" What am I doing wrong? Thanks,

  • Grails script dependency error

    - by Don
    Hi, I have a Grails (GAnt) script with the following target: includeTargets << grailsScript("_GrailsInit") includeTargets << grailsScript("_GrailsPlugins" target('default': "Does something awesome!") { depends(updatePluginsList) // Implementation omitted } Since upgrading to Grails 1.3.1, when I run this I get the error groovy.lang.MissingPropertyException: No such property: updatePluginsList for class: So it appears that the target updatePluginsList has disappeared. This target used to be provided by Grails, so I guess it's either been removed or renamed in a recent release? Thanks, Don

  • Mysterious HttpSession and session-config dependency

    - by OneMoreVladimir
    Good day. I'm developing a Java web app with Servlets\JSP using Tomcat 7.0. During request from client I put and object into the session and use forward. After the forward processing the same request the object can be retreived if the secure parameter is false otherwise it is not stored in session. <session-config> <session-timeout>15</session-timeout> <cookie-config> <http-only>true</http-only> <secure>true</secure> </cookie-config> <tracking-mode>COOKIE</tracking-mode> </session-config> I've figured out that "...cookies can be created with the 'secure' flag, which ensures that the browser will never transmit the specified cookie over non-SSL...". I've configured Tomcat to use SSL, but that haven't helped. Changing the tracking mode to SSL haven't helped as well. How do session-config and HttpSession object correlate in this case? What could be the problem?

  • Should we avoid to use Object as the input parameter/ output value of a method?

    - by developer.cyrus
    Take Java syntax as an example, though the question itself is language independent. If the following snippet takes an object MyAbstractEmailTemplate as input argument in the method setTemplate, the class MyGateway will then become tightly-coupled with the object MyAbstractEmailTemplate, which lessens the re-usability of the class MyGateway. A compromise is to use dependency-injection to ease the instantiation of MyAbstractEmailTemplate. This might solve the coupling problem to some extent, but the interface is still rigid, hardly providing enough ?exibility to other developers/ applications. So if we only use primitive data type (or even plain XML in web service) as the input/ output of a method, it seems the coupling problem no longer exists. So what do you think? public class MyGateway { protected MyAbstractEmailTemplate template; publoc void setTemplate(MyAbstractEmailTemplate template) { this.template = template; } }

  • How to create DataSource dependency property on a wpf User Control

    - by Michael Hedgpeth
    I have a user control that wraps a grid. I want to be able to set the underlying grid's data source, but through the user control, like this: <my:CustomGrid DataSource="{Binding Path=CollectionView}" /> I have set this up in the grid like this: private static readonly DependencyProperty DataSourceProperty = DependencyProperty.Register("DataSource", typeof(IEnumerable), typeof(CustomGrid)); public IEnumerable DataSource { get { return (IEnumerable)GetValue(DataSourceProperty); } set { SetValue(DataSourceProperty, value); underlyingGrid.DataSource = value; } } But this doesn't work (it doesn't give me an error either). The data source is never set. What am I missing?

  • Detected Dependencies - Where is each dependency coming from?

    - by hawbsl
    I have two detected dependencies with the same name (different paths) showing up in my setup project's detected dependencies. One's the "old" one, at an old path. How can i determine which portion of my primary project is causing the "old" one to show up? I can probably do it by trial and error, but is there a quick/direct way?

  • hunting maven dependencies

    - by Tom
    I want to start using maven in code I distribute but I can't find an efficient way to work with dependencies. Every new dependency takes me far too long to add. As a simple example, I need to add Tomcat for compilation. Do I really have to manually trawl the repo in my browser to find the group-id, artifact-id and version number? In every case it seems easier to find the non-maven downloads. I hope I've missed something obvious.

  • Dependency Injection and Moqing

    - by rkrauter
    The way I understand it, DI allows you to use an IoC container to do something like If a constructor needs an IFoo, use a concrete class Foo : IFoo. But how is a Mock object using Moq different? Doesn't it also use DI to create a fake Foo? Thanks.

  • Replace Spring.Net IoC with another Container (e.g. Ninject)

    - by Jeffrey Cameron
    Hey all, I'm curious to know if it's possible to replace Spring.Net's built-in IoC container with Ninject. We use Ninject on my team for IoC in our other projects so I would like to continue using that container if possible. Is this possible? Has anyone written a Ninject-Spring.Net Adapter?? Edit I like many parts of the Spring.Net package (the data access, transactions, etc.) but I don't really like the dependency injection container. I would like to replace that with Ninject Thanks

  • Constructors + Dependency Injection

    - by Sunny
    If I am writing up a class with more than 1 constructor parameter like: class A{ public A(Dependency1 d1, Dependency2 d2, ...){} } I usually create a "argument holder"-type of class like: class AArgs{ public Dependency1 d1 { get; private set; } public Dependency2 d2 { get; private set; } ... } and then: class A{ public A(AArgs args){} } Typically, using a DI-container I can configure the constructor for dependencies & resolve them & so there is minimum impact when the constructors need to change. Is this considered an anti-pattern and/or any arguments against doing this?

  • C++ circular dependency - namespace vs struct

    - by Dead or Alive
    Please educate me. Why does this compile: struct compiles { struct A; struct B { B(const A &a) : member(a.member) { } int member; }; struct A { A(const B &b) : member(b.member) { } int member; }; }; while this does not: namespace doesnt { struct A; struct B { B(const A &a) : member(a.member) { } int member; }; struct A { A(const B &b) : member(b.member) { } int member; }; } (in MSVC 9.0)

  • StructureMap DI on Model Assembly

    - by Dan dot net
    I’m new to Dependency Injection and had a question/need guidance. I had an application that used the repository pattern for data access. I used StructureMap to get the correct repository and all worked well. I have since broken out my model (including the repository logic) into its own assembly and added a service layer. In the interest of DI the service layer class takes an IRepository in its constructor. This seems wrong to me as now all consumers of my model need to know about the repository (at least configure their DI to know which one to use). I feel like that is getting into the guts of the model. What sounds wrong with this?

  • wp7 and dependency property : onChanged and onRead?

    - by user233150
    hi here's my question : well I want build a wp7 control,so I write it and all go well, but the problem is that I can intercept on write(see onItemsSourcePropertyChanged)but not on read I would like explain better: public static readonly DependencyProperty ItemsSourceProperty= DependencyProperty.Register( "ItemsSource", typeof(ObservableCollection<ObjWithDesc>), typeof(HorizontalListBox), new PropertyMetadata(OnItemsSourcePropertyChanged) ); static void OnItemsSourcePropertyChanged(DependencyObject obj,DependencyPropertyChangedEventArgs e) { ((HorizontalListBox) obj).OnItemsSourcePropertyChanged(e); } OnItemsSourcePropertyChanged is called when I use SetValue(dp,..) but there isn't onItemsSourcePropertyRead ? that is called when I Use GetValue()? thanks

  • Tied up with injection implemented with setter functions

    - by puudeli
    Hi, I'm trying to use Scala as part of an existing Java application and now I run into an issue with dependencies injected with a setter method (no DI frameworks in this part of code). How is this handled in a Scala way? In Scala both val and var require to be initialized when declared but I can't do that, since the Java setters inject objects that implement a certain interface and interfaces are abstract and can not be instantiated. class ScalaLogic { var service // How to initialize? def setService (srv: OutputService) = { service = srv } Is there a way to initialize the var service so that I can later assign a dependency into it? It should be lexically scoped to be visible in the whole class.
