• Detecting which MCUs to connect on an incoming conference

  - by Fábio Batista

  Hello, SO. I'm working with the OCS UCCAPI, developing a custom OCS client. I'm currently having a hard time detecting what "kind" of Conference my client is being invited to. Using the Office Communicator client, I can start "IM conferences" (by inviting more than 1 person and selecting "start a IM conversation") or "video conferences" (by selecting more than 1 person and selecting "start a video call"). The Office Communicator client, on the invitees' end, starts correctly the appropriate session (just IM, just Video or IM+Video). However, when receiving the conference invite on my custom client, there's no data about the kind of session I'm being invited. I need this information, in order to make a decision whether or not to connect to the AV MCU and capture/show video. I've tried already: When handling _IUccSessionManagerEvents.OnIncomingSession, parse the RemoteSessionDescription property on the UccIncomingInvitationEvent object: no luck, the only data about the conference modality is an element on the XML about the IM being enabled or not (<im available="true"> or <im available="false">), but nothing about the session having video available or not. When handling _IUccConferenceSessionEvents.OnEnter, check the Media property on the UccConferenceSession. Don't work, all media types are present (MESSAGE, AUDIO, VIDEO, DATA e TELEPHONY), regardless of the type of conference I'm being invited. Also when handling _IUccConferenceSessionEvents.OnEnter, check the Entities collection on the UccConferenceView object, to check which MCUs are enabled for this conference. Don't work either, all MUCs are listed as available (IM, AV, DATA and CONTROL), regardless of the type of conference I'm being invited. I'm running out of ideas. Some references I'm using: http://msdn.microsoft.com/en-us/library/bb664307.aspx http://msdn.microsoft.com/en-us/library/dd170830.aspx Thanks a lot.

• Factory pattern vs ease-of-use?

  - by Curtis White

  Background, I am extending the ASP.NET Membership with custom classes and extra tables. The ASP.NET MembershipUser has a protected constructor and a public method to read the data from the database. I have extended the database structure with custom tables and associated classes. Instead of using a static method to create a new member, as in the original API: I allow the code to instantiate a simple object and fill the data because there are several entities. Original Pattern #1 Protected constructor > static CreateUser(string mydata, string, mydata, ...) > User.Data = mydata; > User.Update() My Preferred Pattern #2 Public constructor > newUser = new MembershipUser(); > newUser.data = ... > newUser.ComplextObject.Data = ... > newUser.Insert() > newUser.Load(string key) I find pattern #2 to be easier and more natural to use. But method #1 is more atomic and ensured to contain proper data. I'd like to hear any opinions on pros/cons. The problem in my mind is that I prefer a simple CRUD/object but I am, also, trying to utilize the underlying API. These methods do not match completely. For example, the API has methods, like UnlockUser() and a readonly property for the IsLockedOut

• How to handle EntityExistsException properly?

  - by Ivan Yatskevich

  I have two entities: Question and FavoritesCounter. FavoritesCounter should be created when the question is added to favorites for the first time. Consider a use case when two users tries to add a question to favorites simultaneously - this will cause EntityExistsException when entityManager.persist(counter) is called for the second user. But the code below doesn't work, because when EntityExistsException is thrown, container marks transaction as rollback only and attempt to return getFavoritesCounter(question) fails with javax.resource.ResourceException: Transaction is not active @Stateless public class FavoritesServiceBean implements FavoritesService { ... public void addToFavorites(Question question) { FavoritesCounter counter = getCounter(question); if (counter == null) { counter = createCounter(question); } //increase counter } private FavoritesCounter createCounter(Question question) { try { FavoritesCounter counter = new FavoritesCounter(); counter.setQuestion(question); entityManager.persist(counter); entityManager.flush(); return counter; } catch (EntityExistsException e) { return getFavoritesCounter(question); } } private FavoritesCounter getFavoritesCounter(Question question) { Query counterQuery = entityManager.createQery("SELECT counter FROM FavoritesCounter counter WHERE counter.question = :question"); counterQuery.setParameter("question", question); List<FavoritesCounter> result = counterQuery.getResultList(); if (result.isEmpty()) return null; return result.get(0); } } Question @Entity public class Question implements Serializable { @Id @GeneratedValue(strategy = GenerationType.AUTO) private Long id; //getter and setter for id } FavoritesCounter @Entity public class FavoritesCounter implements Serializable { @Id @GeneratedValue(strategy = GenerationType.AUTO) private Long id; @OneToOne @Column(unique = true) private Question question; //getter and setter } What is the best way to handle such a situation - return already created entity after EntityExistsException?

• problem in displaying a slug with dash

  - by Mac Taylor

  hey guys i made a slug with dash for my stories urls such as : http://stackoverflow.com/questions/482636/fetching-records-with-slug-instead-of-id this is my code to create slug : function Slugit($title) { $title = strip_tags($title); // Preserve escaped octets. $title = preg_replace('|%([a-fA-F0-9][a-fA-F0-9])|', '---$1---', $title); // Remove percent signs that are not part of an octet. $title = str_replace('%', '', $title); // Restore octets. $title = preg_replace('|---([a-fA-F0-9][a-fA-F0-9])---|', '%$1', $title); $title = remove_accents($title); if (seems_utf8($title)) { if (function_exists('mb_strtolower')) { $title = mb_strtolower($title, 'UTF-8'); } $title = utf8_uri_encode($title, 500); } $title = strtolower($title); $title = preg_replace('/&.+?;/', '', $title); // kill entities $title = str_replace('.', '-', $title); $title = preg_replace('/[^%a-z0-9 _-]/', '', $title); $title = preg_replace('/\s+/', '-', $title); $title = preg_replace('|-+|', '-', $title); $title = trim($title, '-'); return $title; } as you can see dashes , up to here , everything is fine but when i click on the link , it can not open and find it my database as it's saved in normal and with no dashes so i wrote something to remove dashes $string = str_replace('-', '&nbsp;', $string); but when there is ? or . in url , then it can not dispaly ! any help to retrieve back the original url ?!

• Fluent Nhibernate causes System.IndexOutOfRangeException on Commit()

  - by Moss

  Hey there. I have been trying to figure out how to configure the mapping with both NH and FluentNH for days, and I think I'm almost there, but not quite. I have the following problem. What I need to do is basically map these two entities, which are simplified versions of the actual ones. Airlines varchar2(3) airlineCode //PK varchar2(50) Aircraft varchar2(3) aircraftCode //composite PK varchar2(3) airlineCode //composite PK, FK referencing PK in Airlines varchar2(50) aircraftName My classes look like class Airline { string AirlineCode; string AirlineName; IList<Aircraft> Fleet; } class Aircraft { Airline Airline; string AircraftCode; string AircraftName; } Using FluentNH, I mapped it like so AirlineMap Table("Airlines"); Id(x => x.AirlineCode); Map(x => x.AirlineName); HasMany<Aircraft>(x => x.Fleet) .KeyColumn("Airline"); AircraftMap Table("Aircraft"); CompositeId() .KeyProperty(x => x.AircraftCode) .KeyReference(x => x.Airline); Map(x => x.AircraftName); References(x => x.Airline) .Column("Airline"); Using Nunit, I'm testing the addition of another aircraft, but upon calling transaction.Commit after session.Save(aircraft), I get an exception: "System.IndexOutOfRangeException : Invalid index 22 for this OracleParameterCollection with Count=22." The Aircraft class (and the table) has 22 properties. Anyone have any ideas?

• How do you cast a LinqToSql Table<TEntity> as a Table<IEntity> where TEntity : IEntity?

  - by DanM

  I'm trying to use DbLinq with a SQLite database, but I'm running into a problem when I try to cast an ITable as a Queryable<TEntity>. There is a known bug in DbLinq (Issue 211), which might be the source of my problem, but I wanted to make sure my code is sound and, if it is, find out if there might be something I can do to work around the bug. Here is the generic repository method that attempts to do the cast: public IQueryable<TEntity> GetAll() { return Table.Cast<TEntity>(); // Table is an ITable } This compiles, but if I pass in the interface IPerson for TEntity and the type of the entities in the table is Person (where Person : IPerson), I'm getting this error from DbLinq: S0133: Implement QueryMethod Queryable.Cast. Why am I trying to do this? I have a library project that doesn't know the type of the entity until runtime, but it does know the interface for the entity. So, I'm trying to cast to the interface type so that my library project can consume the data. Questions: Am I attempting an impossible cast or is this definitely a bug in DbLinq? How else could I go about solving my problem?

• Binding DataGridComboBoxColumn to a one to many entity framework relation

  - by Cristian

  I have two tables in the model, one table contains entries related to the other table in a one to many relations, for example: Table User ID Name Table Comments ID UserID Title Text I want to show a datagrid in a WPF window with two columns, one text column with the User name and another column with a combobox showing all the comments made by the user. The datagrid definition is like this: <DataGrid AutoGenerateColumns="False" [layout options...] Name="dataGrid1" ItemsSource="{Binding}"> <DataGrid.Columns> <DataGridTextColumn Header="Name" Binding="{Binding Path=Name}"/> <DataGridComboBoxColumn Header="Comments" SelectedValueBinding="{Binding Path=UserID}" SelectedValuePath="ID" DisplayMemberPath="Title" ItemsSource="{Binding Path=Comments}" /> </DataGrid.Columns> </DataGrid> in the code I assign the DataContext like this: dataGrid1.DataContext = entities.Users; The entity User has a property named Comments that leads to all the comments made by the user. The queries are returning data and the user names are shown but the combobox is not being filled. May be the approach is totally wrong or I'm just missing a very simple point here, I'm opened to learn better methods to do this. Thanks

• Backend raising (INotify)PropertyChanged events to all connected clients?

  - by Jörg Battermann

  One of our 'frontend' developers keeps requesting from us backend developers that the backend notifies all connected clients (it's a client/server environment) of changes to objects. As in: whenever one user makes a change, all other connected clients must be notified immediately of the change. At the moment our architecture does not have a notification system of that kind and we don't have a sort of pub/sub model for explicitly chosen objects (e.g. the one the frontend is currently implementing).. which would make sense in such a usecase imho, but obviously requires extra implementation. However, I thought frontends typically check for locks for concurrently existing user changes on the same object and rather pull for changes / load on demand and in the background rather than the backend pushing all changes to all clients for all objects constantly.. which seems rather excessive to me. However, it's being argumented that e.g. the MS Entity Framework does in fact publish (INotify)PropertyChanged not only for local changes, but for all such changes including other client connections, but I have found no proof or details regarding this. Can anyone shed some light into this? Do other e.g. ORMs etc provide broadcasted (INotify)PropertyChanged events on entities?

• Entity Framework lazy loading doesn't work from other thread

  - by Thomas Levesque

  Hi, I just found out that lazy loading in Entity Framework only works from the thread that created the ObjectContext. To illustrate the problem, I did a simple test, with a simple model containing just 2 entities : Person and Address. Here's the code : private static void TestSingleThread() { using (var context = new TestDBContext()) { foreach (var p in context.Person) { Console.WriteLine("{0} lives in {1}.", p.Name, p.Address.City); } } } private static void TestMultiThread() { using (var context = new TestDBContext()) { foreach (var p in context.Person) { Person p2 = p; // to avoid capturing the loop variable ThreadPool.QueueUserWorkItem( arg => { Console.WriteLine("{0} lives in {1}.", p2.Name, p2.Address.City); }); } } } The TestSingleThread method works fine, the Address property is lazily loaded. But in TestMultiThread, I get a NullReferenceException on p2.Address.City, because p2.Address is null. It that a bug ? Is this the way it's supposed to work ? If so, is there any documentation mentioning it ? I couldn't find anything on the subject on MSDN or Google... And more importantly, is there a workaround ? (other than explicitly calling LoadProperty from the worker thread...) Any help would be very appreciated PS: I'm using VS2010, so it's EF 4.0. I don't know if it was the same in the previous version of EF...

• Can this be considered Clean Code / Best Practice?

  - by MRFerocius

  Guys, How are you doing today? I have the following question because I will follow this strategy for all my helpers (to deal with the DB entities) Is this considered a good practice or is it going to be unmaintainable later? public class HelperArea : AbstractHelper { event OperationPerformed<Area> OnAreaInserting; event OperationPerformed<Area> OnAreaInserted; event OperationPerformed<Area> OnExceptionOccured; public void Insert(Area element) { try { if (OnAreaInserting != null) OnAreaInserting(element); DBase.Context.Areas.InsertOnSubmit(new AtlasWFM_Mapping.Mapping.Area { areaDescripcion = element.Description, areaNegocioID = element.BusinessID, areaGUID = Guid.NewGuid(), areaEstado = element.Status, }); DBase.Context.SubmitChanges(); if (OnAreaInserted != null) OnAreaInserted(element); } catch (Exception ex) { LogManager.ChangeStrategy(LogginStrategies.EVENT_VIEWER); LogManager.LogError(new LogInformation { logErrorType = ErrorType.CRITICAL, logException = ex, logMensaje = "Error inserting Area" }); if (OnExceptionOccured != null) OnExceptionOccured(elemento); } } I want to know if it is a good way to handle the event on the Exception to let subscribers know that there has been an exception inserting that Area. And the way to log the Exception, is is OK to do it this way? Any suggestion to make it better?

• Jackson object mapping - map incoming JSON field to protected property in base class

  - by Pete

  We use Jersey/Jackson for our REST application. Incoming JSON strings get mapped to the @Entity objects in the backend by Jackson to be persisted. The problem arises from the base class that we use for all entities. It has a protected id property, which we want to exchange via REST as well so that when we send an object that has dependencies, hibernate will automatically fetch these dependencies by their ids. Howevery, Jackson does not access the setter, even if we override it in the subclass to be public. We also tried using @JsonSetter but to no avail. Probably Jackson just looks at the base class and sees ID is not accessible so it skips setting it... @MappedSuperclass public abstract class AbstractPersistable<PK extends Serializable> implements Persistable<PK> { @Id @GeneratedValue(strategy = GenerationType.AUTO) private PK id; public PK getId() { return id; } protected void setId(final PK id) { this.id = id; } Subclasses: public class A extends AbstractPersistable<Long> { private String name; } public class B extends AbstractPersistable<Long> { private A a; private int value; // getter, setter // make base class setter accessible @Override @JsonSetter("id") public void setId(Long id) { super.setId(id); } } Now if there are some As in our database and we want to create a new B via the REST resource: @POST @Consumes(MediaType.APPLICATION_JSON) @Produces(MediaType.APPLICATION_JSON) @Transactional public Response create(B b) { if (b.getA().getId() == null) cry(); } with a JSON String like this {"a":{"id":"1","name":"foo"},"value":"123"}. The incoming B will have the A reference but without an ID. Is there any way to tell Jackson to either ignore the base class setter or tell it to use the subclass setter instead? I've just found out about @JsonTypeInfo but I'm not sure this is what I need or how to use it. Thanks for any help!

• IoC and dataContext disposing in asp.net mvc 2 application

  - by zerkms

  I have the Global.asax like the code below: public class MvcApplication : System.Web.HttpApplication { public static void RegisterRoutes(RouteCollection routes) { // .... } protected void Application_Start() { AreaRegistration.RegisterAllAreas(); RegisterRoutes(RouteTable.Routes); ControllerBuilder.Current.SetControllerFactory(typeof(IOCControllerFactory)); } } public class IOCControllerFactory : DefaultControllerFactory { private readonly IKernel kernel; public IOCControllerFactory() { kernel = new StandardKernel(new NanocrmContainer()); } protected override IController GetControllerInstance(RequestContext requestContext, Type controllerType) { if (controllerType == null) return base.GetControllerInstance(requestContext, controllerType); var controller = kernel.TryGet(controllerType) as IController; if (controller == null) return base.GetControllerInstance(requestContext, controllerType); var standartController = controller as Controller; if (standartController is IIoCController) ((IIoCController)standartController).SetIoc(kernel); return standartController; } class NanocrmContainer : Ninject.Modules.NinjectModule { public override void Load() { // ... Bind<DomainModel.Entities.db>().ToSelf().InRequestScope().WithConstructorArgument("connection", "Data Source=lims;Initial Catalog=nanocrm;Persist Security Info=True;User ID=***;Password=***"); } } } In this case if somewhere it is the class, defined like: public class UserRepository : IUserRepository { private db dataContext; private IUserGroupRepository userGroupRepository; public UserRepository(db dataContext, IUserGroupRepository userGroupRepository) { this.dataContext = dataContext; this.userGroupRepository = userGroupRepository; } } then the dataContext instance is created (if no one was created in this request scope) by Ninject. So the trouble now is - where to invoke dataContext method .Dispose()?

• Entity Framework - Merging 2 physical tables into one "virtual" table problems...

  - by Keith Barrows

  I have been reading up on porting ASP.NET Membership Provider into .NET 3.5 using LINQ & Entities. However, the DB model that every single sample shows is the newer model while I've inherited a rather old model. Differences: The User Table is split into a pair of User & Membership Tables. All of the tables in the DB are prepended with aspnet_ I have Lowered versions of some columns (UserName, Email, etc) To work with this I have copied the properties from the Membership table into the User table (in the DB this is a 1<-1 relationship, not a 1<-0,1), renamed aspnet_Applications to Application, aspnet_Profiles to Profile, aspnet_Users to User and aspnet_Roles to Role. (See image) Link to full size image of model Now, I am running into one of 2 problems when I try to compile. Using the model in the image I get this error: Problem in Mapping Fragment starting at line 464: EntitySets 'UserSet' and 'aspnet_Membership' are both mapped to table 'aspnet_Membership'. Their Primary Keys may collide. If I delete the aspnet_Membership table from my model (to handle the above error) I then get: Problem in Mapping Fragment starting at line 384: Column aspnet_Membership.ApplicationId in table aspnet_Membership must be mapped: It has no default value and is not nullable. My ability to hand edit the backing stores is not the best and I don't want to just hack something in that may break other things. I am looking for suggestions, best practices, etc to handle this. Note: Moving the data tables themselves is not an option as I cannot replace all the logic in the existing apps. I am building this EF Provider for a new App. Over the next 6 months the old app(s) will migrate bit-by-bit to the new structures. Note: I added a link just under the image to the full size image for better viewing.

• Fluent config not generating mapping files

  - by rboarman

  Hello, I am trying to get Fluent nHibernate to generate mappings so I can take a look at the files and the sql. My code is based on this post and on what I can glean from the documentation. http://stackoverflow.com/questions/1375146/fluent-mapping-entities-and-classmaps-in-different-assemblies I am using the latest code from git. Here’s my config code: Configuration cfg = new Configuration(); var ft = Fluently.Configure(cfg); //DbConnection by fluent ft.Database ( MsSqlConfiguration .MsSql2008 .ConnectionString("……") .ShowSql() .UseReflectionOptimizer() ); //get mapping files. ft.Mappings(m => { //set up the mapping locations m.FluentMappings.AddFromAssemblyOf<Entity>() .ExportTo(@"C:\temp"); m.Apply(cfg); }); I also tried: var sessionFactory = Fluently.Configure() .Database(MsSqlConfiguration .MsSql2008 .ShowSql() .ConnectionString(“……")) .Mappings(p => p.FluentMappings .AddFromAssemblyOf<Entity>() .ExportTo(@"c:\temp\")) .BuildSessionFactory(); I have verified that the connection string is correct. The issue is that no mapping files show up in the ExportTo folder and no sql code shows up in the output window or in the log file. No errors or exceptions are generated either. I have no idea where to go from here. Thank you in advance. Rick

• Spell checker software

  - by Naren

  Hello Guys, I have been assigned a task to find a decent spell checker (UK English) preferably the free one for a project that we are doing. I have looked at Google AJAX API for this. The project contains some young person's (kids less than 18 years old) data which shouldn't allow exposing or storing outside the application boundaries. Google logs the data for research purpose that means Google owns the data whatever we send over the wire through Google API. Is this right? I fired an email to Google regarding the privacy of data and storage but they haven't come back. If you have some knowledge regarding this please share with me. At this point our servers might not have access to external entities that means we might not be able to use Web API for this over the wire. But it may change in the future. That means I have to find out some spell checker alternatives that can sit in our environment and do the job or an external APIs. Would you mind share your findings and knowledge in this regard. I would prefer free services but never know if you have some cracking spell checker for a few quid’s then I don't mind recommending to the project board. Technology using ASP.NET 3.5/4.0, MVC, jQuery, SQL Sever 2008 etc Cheers, Naren

• Service Oriented Architecture & Domain-Driven Design

  - by Michael

  I've always developed code in a SOA type of way. This year I've been trying to do more DDD but I keep getting the feeling that I'm not getting it. At work our systems are load balanced and designed not to have state. The architecture is: Website ===Physical Layer== Main Service ==Physical Layer== Server 1/Service 2/Service 3/Service 4 Only Server 1,Service 2,Service 3 and Service 4 can talk to the database and the Main Service calls the correct service based on products ordered. Every physical layer is load balanced too. Now when I develop a new service, I try to think DDD in that service even though it doesn't really feel like it fits. I use good DDD principles like entities, value types, repositories, aggregates, factories and etc. I've even tried using ORM's but they just don't seem like they fit in a stateless architecture. I know there are ways around it, for example use IStatelessSession instead of ISession with NHibernate. However, ORM just feel like they don't fit in a stateless architecture. I've noticed I really only use some of the concepts and patterns DDD has taught me but the overall architecture is still SOA. I am starting to think DDD doesn't fit in large systems but I do think some of the patterns and concepts do fit in large systems. Like I said, maybe I'm just not grasping DDD or maybe I'm over analyzing my designs? Maybe by using the patterns and concepts DDD has taught me I am using DDD? Not sure if there is really a question to this post but more of thoughts I've had when trying to figure out where DDD fits in overall systems and how scalable it truly is. The truth is, I don't think I really even know what DDD is?

• noSQL/SQL/RoR: Trying to build scalable ratings table for the game

  - by alexeypro

  I am trying to solve complex thing (as it looks to me). I have next entities: PLAYER (few of them, with names like "John", "Peter", etc.). Each has unique ID. For simplicity let's think it's their name. GAME (few of them, say named "Hide and Seek", "Jump and Run", etc.). Same - each has unique ID. For simplicity of the case let it be it's name for now. SCORE (it's numeric). So, how it works. Each PLAYER can play in multiple GAMES. He gets some SCORE in every GAME. I need to build rating table -- and not one! Table #1: most played GAMES Table #2: best PLAYERS in all games (say the total SCORE in every GAME). Table #3: best PLAYERS per GAME (by SCORE in particularly that GAME). I could be build something straight right away, but that will not work. I will have more than 10,000 players; and 15 games, which will grow for sure. Score can be as low as 0, and as high as 1,000,000 (not sure if higher is possible at this moment) for player in the game. So I really need some relative data. Any suggestions? I am planning to do it with SQL, but may be just using it for key-value storage; anything -- any ideas are welcome. Thank you!

• Dynamic where clause using Linq to SQL in a join query in a MVC application

  - by jhoefnagels

  Dear .Net Linq experts, I am looking for a way to query for products in a catalog using filters on properties which have been assigned to the product based on the category to which the product belongs. So I have the following entities involved: Products -Id -CategoryId Categories [Id] Properties [Id, CategoryId] PropertyValues [Id, PropertyId] ProductProperties [ProductId, PropertyValueId] When I ad a product to the catalog, multiple ProductProperties will be added based on the category and I would like to be able to filter all products from a category by selecting values for one or more properties. I will gather all filters, which I will hold in a list, by reading the URL. Now it is time to actually get the products based on multiple properties and I have been trying to find the right strategy but untill now it does not really work. Is there a way to make this work without writing SQL? I was trying something like this: productsInCategory = ProductRepository.Where(p => p.Category.Name == category); foreach (PropertyFilter pf in filterList) { productsInCategory = (from product in productsInCategory join pp in ProductPropertyRepository on product.Id equals pp.ProductId where pp.PropertyValueId == pf.ValueId select product); }

• maven dependencies and jetty - avoiding deploy

  - by James Cooper

  Hi, I have a project with 3 artifacts: common - entities, business logic. no UI code webapp-a - a public web app webapp-b - an admin web app webapp-a and webapp-b depend on common. common is configured to deploy to a local maven repo. so far so good. I have IntelliJ configured so that each artifact is a separate module. Module dependencies are configured properly. I can add a new method to a class in common and immediately use that method in a class in a webapp. However, when I run mvn jetty:run it uses the currently deployed common snapshot in my repository. It does not use my local classes. If I add a method to a class in common, it compiles fine, but blows up at runtime. So is it possible to either: a) Convince jetty:run to use my local common build output or b) Deploy my common output to my local ~/.m2/repo while I'm testing locally before I want to commit/deploy or c) some other solution? thank you! -- James

• MonoRail: Testing, Route Extensions, Folder Structures

  - by Kezzer

  I've got a few questions related to the use of MonoRail Testing Does everyone tend to use NUnit for their testing? I haven't worked enough with testing to know if this is a good testing framework to use. I'm just looking to get more into testing my applications a lot more than before and wanted to know if there's any general guidelines. Are you supposed to copy the controller over to a test area and just rename it with test in the name and re-run it? How do you ensure your test project and main project coincide with one another? Is it just a case of copying everything over again or are there tools available to do it for you? Route Extensions MonoRail tends to use <action>.rails, can you omit the .rails part if you configure your routing correctly? Why does this seem to be the standard? Folder Structures I haven't found anywhere which really points out your standard folder structure. Sure, you have Controllers, Models, and Views. But your Models folder should contain your data access objects as well. I've seen some have something like -> Models -> DaoClasses -> Entities But what about custom structures used to get data out of views? And if you're using NHibernate, where's a good place to stick the mappings? I know it's entirely dependent on the developer, but I haven't really seen any standard approach. Cheers

• ASP.NET MVC 2: Mechanics behind an Order / Order Line in a edit form

  - by Dr. Zim

  In this question I am looking for links/code to handle an IList<OrderLine> in an MVC 2 edit form. Specifically I am interested in sending a complete order to the client, then posting the edited order back to an object (to persist) using: Html.EditorFor(m = m.orderlines[i]) (where orderlines is an enumerable object) Editing an Order that has multiple order lines (two tables, Order and OrderLine, one to many) is apparently difficult. Is there any links/examples/patterns out there to advise how to create this form that edits an entity and related entities in a single form (in C# MVC 2)? The IList is really throwing me for a loop. Should I have it there (while still having one form to edit one order)? How could you use the server side factory to create a blank OrderLine in the form while not posting the entire form back to the server? I am hoping we don't treat the individual order lines with individual save buttons, deletes, etc. (for example, they may open an order, delete all the lines, then click cancel, which shouldn't have altered the order itself in either the repository nor the database. Example classes: public class ViewModel { public Order order {get;set;} // Only one order } public class Order { public int ID {get;set;} // Order Identity public string name {get;set;} public IList<OrderLine> orderlines {get;set;} // Order has multiple lines } public class OrderLine { public int orderID {get;set;} // references Order ID above public int orderLineID {get;set;} // Order Line identity (need?) public Product refProduct {get;set;} // Product value object public int quantity {get;set;} // How many we want public double price {get;set;} // Current sale price }

Technologies: Entity framework 4.0 .Net 4.0 namespace Sample.Data.Store.Entities { public partial class StoreDB { public override int SaveChanges(System.Data.Objects.SaveOptions options) { for (Int32 attempt = 1; ; ) { try { return base.SaveChanges(options); } catch (SqlException sqlException) { // Increment Trys attempt++; // Find Maximum Trys Int32 maxRetryCount = 5; // Throw Error if we have reach the maximum number of retries if (attempt == maxRetryCount) throw; // Determine if we should retry or abort. if (!RetryLitmus(sqlException)) throw; else Thread.Sleep(ConnectionRetryWaitSeconds(attempt)); } } } static Int32 ConnectionRetryWaitSeconds(Int32 attempt) { Int32 connectionRetryWaitSeconds = 2000; // Backoff Throttling connectionRetryWaitSeconds = connectionRetryWaitSeconds * (Int32)Math.Pow(2, attempt); return (connectionRetryWaitSeconds); } /// <summary> /// Determine from the exception if the execution /// of the connection should Be attempted again /// </summary> /// <param name="exception">Generic Exception</param> /// <returns>True if a a retry is needed, false if not</returns> static Boolean RetryLitmus(SqlException sqlException) { switch (sqlException.Number) { // The service has encountered an error // processing your request. Please try again. // Error code %d. case 40197: // The service is currently busy. Retry // the request after 10 seconds. Code: %d. case 40501: //A transport-level error has occurred when // receiving results from the server. (provider: // TCP Provider, error: 0 - An established connection // was aborted by the software in your host machine.) case 10053: return (true); } return (false); } } } The problem: How can I run the StoreDB.SaveChanges to retry on a new DB context after an error occured? Something simular to Detach/Attach might come in handy. Thanks in advance! Bart

• FluentNHibernate Overrides: UseOverridesFromAssemblyOf non-generic version

  - by ThiagoAlves

  Hi, I have a repository class that inherits from a generic implementation: public namespace RepositoryImplementation { public class PersonRepository : Web.Generics.GenericNHibernateRepository<Person> } The generic repository implementation uses Fluent NHibernate conventions. They're working fine. One of those conventions is that all properties are not nullable. Now I need to define that specific properties may be nullable outside the conventions. Fluent NHibernate has an interesting override mechanism: public namespace RepositoryImplementation { public class PersonMappingOverride : IAutoMappingOverride<Person> { public void Override(FluentNHibernate.Automapping.AutoMapping<Funcionario> mapping) { mapping.Map(x => x.PhoneNumber).Nullable(); } } } Now I need to register the override class into Fluent NHibernate. I have the following code in the Web.Generics.GenericNHibernateRepository generic class: AutoMap.AssemblyOf<Person>() .Where(type => type.Namespace == "Entities") .UseOverridesFromAssemblyOf<PersonMappingOverride>(); The problem is: UseOverridesFromAssemblyOf is a generic method, and I can't do something like that: .UseOverridesFromAssemblyOf<PersonMappingOverride>(); Because that would cause a circular reference. I don't want the generic repository to know the either repository or the mapping override class, because they vary from project to project. I see another solution: in the GenericNHibernateRepository class I can do this.GetType() and get the repository implementation type (e.g.: PersonRepository). However I can't call UseOverridesFromAssemblyOf() passing a type. Is there another way to configure overrides in FluentNHibernate? If not, how could I call UseOverridesFromAssemblyOf<T> without making the generic repository depend upon the repository implementation or the mapping override class?

• Deriving an HTMLElement Object from jQuery Object

  - by Jasconius

  I'm doing a fairly exhaustive series of DOM manipulations where a few elements (specifically form elements) have some events. I am dynamically creating (actually cloning from a source element) several boxes and assigning a change() event to them. The change event executes, and within the context of the event, "this" is the HTML Element Object. What I need to do at this point however is determine a contact for this HTML Element Object. I have these objects stored already as jQuery entities in assorted arrays, but obviously [HTMLElement Object] != [Object Object] And the trick is that I cannot cast $(this) and make a valid comparison since that would create a new object and the pointer would be different. So... I've been banging my head against this for a while. In the past I've been able to circumvent this problem by doing an innerHTML comparison, but in this case the objects I am comparing are 100% identical, just there's lots of them. Therefore I need a solid comparison. This would be easy if I could somehow derive the HTMLElement object from my originating jQuery object. Thoughts, other ideas? Help. :(

• Serious Application Error

  - by Garry

  I have a TableView controller class that uses a fetched results controller to display a list of 'patient' entities taken from a Core Data model. The sections of this table are taken from a patient attribute called 'location'. Here is the sort descriptor for the fetch request: NSSortDescriptor *locationDescriptor = [[NSSortDescriptor alloc] initWithKey:@"location" ascending:YES]; NSSortDescriptor *lastNameDescriptor = [[NSSortDescriptor alloc] initWithKey:@"lastName" ascending:YES]; NSArray *sortDescriptors = [[NSArray alloc] initWithObjects:locationDescriptor, lastNameDescriptor, nil]; Here is the initialisation code for the FRC: NSFetchedResultsController *aFetchedResultsController = [[NSFetchedResultsController alloc] initWithFetchRequest:fetchRequest managedObjectContext:managedObjectContext sectionNameKeyPath:@"location" cacheName:@"List"]; When I want to add a new 'patient' entity - I click an add button which then pushes an 'add new patient' view controller to the navigation stack. The first patient I add works fine. If I add a second patient - the app will sometimes crash with the following error: 2010-03-22 14:42:05.270 Patients[1126:207] Serious application error. Exception was caught during Core Data change processing: * -[NSCFArray insertObject:atIndex:]: index (1) beyond bounds (1) with userInfo (null) 2010-03-22 14:42:05.272 Patients[1126:207] Terminating app due to uncaught exception 'NSRangeException', reason: '** -[NSCFArray insertObject:atIndex:]: index (1) beyond bounds (1)' This only seems to happen if the patient's have a location added (if none is added then the location defaults to 'unknown'). It seems to have something to do with the sorting of the location too. For instance, if the first patient location = ward 14 and the second = ward 9 then it crashes without fail. I'm wondering if this is something to do with how I am asking the fetched results controller to sort the section names?? This bug is driving me nuts and I just can't figure it out. Any help would be greatly appreciated!
