  • MVC EditorFor bind to type in array

    - by BradBrening
    I have a ViewModel that, among other properties, contains an array of 'EmailAddress' objects. EmailAddress itself has properties such as "Address", and "IsPrimary". My view model breakdown is: public class UserDetailsViewModel { public BUser User { get; set; } public string[] Roles { get; set; } public EmailAddress[] EmailAddresses { get; set; } } I am showing a "User Details" page that is pretty standard. For example, I'm displaying data using @Html.DisplayFor(model => model.User.UserName) and @Html.DisplayFor(model => model.User.Comment) I also have a section on the page that lists all of the EmailAddress objects associated with the user: @if(Model.EmailAddresses.Length > 0) { foreach (var address in Model.EmailAddresses) { <div> @Html.DisplayFor(model => address.Address) </div> } } else { <div class="center">User does not have any email addresses.</div> } My problem is that I would like to show an "Add Email Address" form above the list of email addresses. I thought I would take the "normal" approach thusly: @using(Html.BeginForm(new { id=Model.User.UserName, action="AddUserEmailAddress" })) { <text>Address:</text> @Html.EditorFor(model => ** HERE I AM STUCK **) <input type="submit" value="Add Email" class="button" /> } As you may be able to tell, I am stuck here. I've tried model => Model.EmailAddresses[0] and model => Model.EmailAddresses.FirstOrDefault(). Both of these have failed horribly. I am sure that I am going about this all wrong. I've even thought of adding a "dummy" property to my ViewModel of type EmailAddress just so that I can bind to that in my EditorFor - but that seems to be a really bad hack. There has to be something simple that I'm overlooking! I would appreciate any help anyone can offer with this matter. Thank you in advance!

  • MetadataType and client validation in ASP.NET MVC 2

    - by Kristoffer Ahl
    Inherited properties and MetadataType does not seem to work with client side validation in ASP.NET MVC 2. The validation of our MetadataTypes work as expected on the server but for some reason it does not generate the appropriate client scripts for it. Client side validation kicks in as expected for properties with the DataAnnotations attributes set on the PersonView so I know that client side validation is active and that it works. Does anyone know if or how it can be fixed? Here's what we have: public abstract class PersonView { public string FirstName { get; set; } public string LastName { get; set; } public string Email { get; set; } [Required] public string PhoneNumber { get; set; } public string AddressLine1 { get; set; } public string AddressLine2 { get; set; } public string AddressZipCode { get; set; } public string AddressCity { get; set; } public string AddressCountry { get; set; } } [MetadataType(typeof(CustomerViewMetaData))] public class CustomerView : PersonView {} [MetadataType(typeof(GuestViewMetaData))] public class GuestView : PersonView {} public class GuestViewMetaData { [Required(ErrorMessage = "The guests firstname is required")] public string FirstName { get; set; } [Required(ErrorMessage = "The guests lastname is required")] public string LastName { get; set; } } public class CustomerViewMetaData { [Required(ErrorMessage = "The customers firstname is required")] public string FirstName { get; set; } [Required(ErrorMessage = "The customers lastname is required")] public string LastName { get; set; } [Required(ErrorMessage = "The customers emails is required")] public string Email { get; set; } } As you can see, it's nothing fancy or strange in there... Can it be fixed? Is it a bug in ASP.NET MVC 2?

  • How to manage maintenance/bug-fix branches in Subversion when third-party installers are involved?

    - by Mike Spross
    We have a suite of related products written in VB6, with some C# and VB.NET projects, and all the source is kept in a single Subversion repository. We haven't been using branches in Subversion (although we do tag releases now), and simply do all development in trunk, creating new releases when the trunk is stable enough. This causes no end of grief when we release a new version, issues are found with it, and we have already begun working on new features or major changes to the trunk. In the past, we would address this in one of two ways, depending on the severity of the issues and how stable we thought the trunk was: Hurry to stabilize the trunk, fix the issues, and then release a maintenance update based on the HEAD revision, but this had the side effect of releases that fixed the bugs but introduced new issues because of half-finished features or bugfixes that were in trunk. Make customers wait until the next official release, which is usually a few months. We want to change our policies to better deal with this situation. I was considering creating a "maintenance branch" in Subversion whenever I tag an official release. Then, new development would continue in trunk, and I can periodically merge specific fixes from trunk into the maintenance branch, and create a maintenance release when enough fixes are accumulated, while we continue to work on the next major update in parallel. I know we could also have a more stable trunk and create a branch for new updates instead, but keeping current development in trunk seems simpler to me. The major problem is that while we can easily branch the source code from a release tag and recompile it to get the binaries for that release, I'm not sure how to handle the setup and installer projects. We use QSetup to create all of our setup programs, and right now when we need to modify a setup project, we just edit the project file in-place (all the setup projects and any dependencies that we don't compile ourselves are stored on a separate server, and we make sure to always compile the setup projects on that machine only). However, since we may add or remove files to the setup as our code changes, there is no guarantee that today's setup projects will work with yesterday's source code. I was going to put all the QSetup projects in Subversion to deal with this, but I see some problems with this approach. I want the creation of setup programs to be as automated as possible, and at the very least, I want a separate build machine where I can build the release that I want (grabbing the code from Subversion first), grab the setup project for that release from Subversion, recompile the setup, and then copy the setup to another place on the network for QA testing and eventual release to customers. However, when someone needs to change a setup project (to add a new dependency that trunk now requires or to make other changes), there is a problem. If they treat it like a source file and check it out on their own machine to edit it, they won't be able to add files to the project unless they first copy the files they need to add to the build machine (so they are available to other developers), then copy all the other dependencies from the build machine to their machine, making sure to match the folder structure exactly. The issue here is that QSetup uses absolute paths for any files added to a setup project. However, this means installing a bunch of setup dependencies onto development machines, which seems messy (and which could destabilize the development environment if someone accidentally runs the setup project on their machine). Also, how do we manage third-party dependencies? For example, if the current maintenance branch used MSXML 3.0 and the trunk now requires MSXML 4.0, we can't go back and create a maintenance release if we have already replaced the MSXML library on the build machine with the latest version (assuming both versions have the same filename). The only solution I can think is to either put all the third-party dependencies in Subversion along with the source code, or to make sure we put different library versions in separate folders (i.e. C:\Setup\Dependencies\MSXML\v3.0 and C:\Setup\Dependencies\MSXML\v4.0). Is one way "better" or more common than the other? Are there any best practices for dealing with this situation? Basically, if we release v2.0 of our software, we want to be able to release v2.0.1, v2.0.2, and v.2.0.3 while we work on v2.1, but the whole setup/installation project and setup dependency issue is making this more complicated than the the typical "just create a branch in Subversion and recompile as needed" answer.

  • Makefile option/rule to handle missing/removed source files

    - by b3nj1
    http://stackoverflow.com/questions/239004/need-a-makefile-dependency-rule-that-can-handle-missing-files gives some pointers on how to handle removed source files for generating .o files. I'm using gcc/g++, so adding the -MP option when generating dependencies works great for me, until I get to the link stage with my .a file... What about updating archives/libraries when input sources go away? This works OK for me, but is there a cleaner way (ie, something as straightforward as the g++ -MP option)? #BUILD_DIR is my target directory (includes Debug/Release and target arch) #SRC_OUTS are my .o files LIBATLS_HAS = $(shell nm ${BUILD_DIR}/libatls.a | grep ${BUILD_DIR} | sed -e 's/.*(//' -e 's/).*://') LIBATLS_REMOVE = $(filter-out $(notdir ${SRC_OUTS}), ${LIBATLS_HAS}) ${BUILD_DIR}/libatls.a: ${BUILD_DIR}/libatls.a(${SRC_OUTS}) ifneq ($(strip ${LIBATLS_REMOVE}),) $(AR) -d $@ ${LIBATLS_REMOVE} endif

    I am trying for the first time to install some Ruby gems on Mac OS X Leopard. Please see the command and the output below. My question is how do I install a gem with dependencies? I tried installing individual dependency gems first from a locally downloaded files but I soon found out that there is no end to the rabbit hole :-) I also found out that there are circular dependencies that break even this tedious method. There must be a better way! I would really appreciate your help. sudo gem install oauth Updating metadata for 1 gems from http://gems.rubyforge.org . complete ERROR: Error installing oauth: oauth requires actionpack (>= 2.2.0, < 2.3.0)

  • Id property not populated

    - by fingers
    I have an identity mapping like so: Id(x => x.GuidId).Column("GuidId") .GeneratedBy.GuidComb().UnsavedValue(Guid.Empty); When I retrieve an object from the database, the GuidId property of my object is Guid.Empty, not the actual Guid (the property in the class is of type System.Guid). However, all of the other properties in the object are populated just fine. The database field's data type (SQL Server 2005) is uniqueidentifier, and marked as RowGuid. The application that is connecting to the database is a VB.NET Web Site project (not a "Web Application" or "MVC Web Application" - just a regular "Web Site" project). I open the NHibernate session through a custom HttpModule. Here is the HttpModule: public class NHibernateModule : System.Web.IHttpModule { public static ISessionFactory SessionFactory; public static ISession Session; private static FluentConfiguration Configuration; static NHibernateModule() { if (Configuration == null) { string connectionString = cfg.ConfigurationManager.ConnectionStrings["myDatabase"].ConnectionString; Configuration = Fluently.Configure() .Database(MsSqlConfiguration.MsSql2005.ConnectionString(cs => cs.Is(connectionString))) .ExposeConfiguration(c => c.Properties.Add("current_session_context_class", "web")) .Mappings(x => x.FluentMappings.AddFromAssemblyOf<LeadMap>().ExportTo("C:\\Mappings")); } SessionFactory = Configuration.BuildSessionFactory(); } public void Init(HttpApplication context) { context.BeginRequest += delegate { Session = SessionFactory.OpenSession(); CurrentSessionContext.Bind(Session); }; context.EndRequest += delegate { CurrentSessionContext.Unbind(SessionFactory); }; } public void Dispose() { Session.Dispose(); } } The strangest part of all, is that from my unit test project, the GuidId property is returned as I would expect. I even rigged it to go for the exact row in the exact database as the web site was hitting. The only differences I can think of between the two projects are The unit test project is in C# Something with the way the session is managed between the HttpModule and my unit tests The configuration for the unit tests is as follows: Fluently.Configure() .Database(MsSqlConfiguration.MsSql2005.ConnectionString(cs => cs.Is(connectionString))) .Mappings(x => x.FluentMappings.AddFromAssemblyOf<LeadDetailMap>()); I am fresh out of ideas. Any help would be greatly appreciated. Thanks

  • Why attached property Set and Get static methods are not called in XAML?

    - by JD
    Hi, I have set break points on my attached properties SetXXX and GetXXX static methods. In Xaml, I have assigned values to the attached property. However, I was expecting the Set or Get static methods to be called but they are not. The attached property works as expected and if I call SetXXX and GetXXX methods in code, then it works are expected. Why are the methods not called when set from Xaml? JD.

  • EJB-like plug-in to VS2008?

    - by Phil
    I'd like to be able to just write a class and get a table generated in my DB along with all the properties of that class. In EJB it's possible to let the container handle the data and "sync" with the DB. I'd like something like this in VS2008 with C# .NET and ASP.NET. Is there anything remotely like this on the market?

  • Tomcat servlet-api.jar problem

    - by CitadelCSCadet
    I am running a web application using Tomcat and Java Servlets, JSP's, etc. I am aware that in order to use Servlets, it is dependent on the Servlet-api.jar file. Initially I placed this jar file in the WEB-INF/lib/ directory. This has worked fine for me for months during the developmental phase. When we put the application onto the server space we are using, we started seeing wierd problems showing up in the Catalina.out file telling us that there was dependency problems with the servlet-api.jar file. I am aware that tomcat has this jar file in its container, and that I should remove it from the WEB-INF/lib/ directory. I have tried this and it does not work. What do I have to do when I remove this jar file from the local files and allow it to depend on tomcats servlet-api.jar file.

  • Lotus view column compare to string/integer

    - by Kris.Mitchell
    I have a lotus view that stores a number. I need to perform some math against the value, but I am having a lot of problems getting the types to match up. doc.numOfGold = numGold and CInt(doc.numOfGold) = numGold and CInt(doc.numOfGold) = CInt(numGold) and doc.numOfGold = CInt(numGold) all return type mismatch. I've tried changing the column properties to treat it as a decimal, with no better luck. Any thoughts? Thanks!

  • Minutia on Objective-C Categories and Extensions.

    - by Matt Wilding
    I learned something new while trying to figure out why my readwrite property declared in a private Category wasn't generating a setter. It was because my Category was named: // .m @interface MyClass (private) @property (readwrite, copy) NSArray* myProperty; @end Changing it to: // .m @interface MyClass () @property (readwrite, copy) NSArray* myProperty; @end and my setter is synthesized. I now know that Class Extension is not just another name for an anonymous Category. Leaving a Category unnamed causes it to morph into a different beast: one that now gives compile-time method implementation enforcement and allows you to add ivars. I now understand the general philosophies underlying each of these: Categories are generally used to add methods to any class at runtime, and Class Extensions are generally used to enforce private API implementation and add ivars. I accept this. But there are trifles that confuse me. First, at a hight level: Why differentiate like this? These concepts seem like similar ideas that can't decide if they are the same, or different concepts. If they are the same, I would expect the exact same things to be possible using a Category with no name as is with a named Category (which they are not). If they are different, (which they are) I would expect a greater syntactical disparity between the two. It seems odd to say, "Oh, by the way, to implement a Class Extension, just write a Category, but leave out the name. It magically changes." Second, on the topic of compile time enforcement: If you can't add properties in a named Category, why does doing so convince the compiler that you did just that? To clarify, I'll illustrate with my example. I can declare a readonly property in the header file: // .h @interface MyClass : NSObject @property (readonly, copy) NSString* myString; @end Now, I want to head over to the implementation file and give myself private readwrite access to the property. If I do it correctly: // .m @interface MyClass () @property (readonly, copy) NSString* myString; @end I get a warning when I don't synthesize, and when I do, I can set the property and everything is peachy. But, frustratingly, if I happen to be slightly misguided about the difference between Category and Class Extension and I try: // .m @interface MyClass (private) @property (readonly, copy) NSString* myString; @end The compiler is completely pacified into thinking that the property is readwrite. I get no warning, and not even the nice compile error "Object cannot be set - either readonly property or no setter found" upon setting myString that I would had I not declared the readwrite property in the Category. I just get the "Does not respond to selector" exception at runtime. If adding ivars and properties is not supported by (named) Categories, is it too much to ask that the compiler play by the same rules? Am I missing some grand design philosophy?
