• EF4 CTP5 - Map foreign key without object references?

  - by anon

  I feel like this should have a simple answer, but I can't find it. I have 2 POCOs: public class Category { public int Id { get; set; } public string Name { get; set; } } public class Product { public int Id { get; set; } public int CategoryId { get; set; } } Notice that there are no object references on either POCO. With Code-First, how do I make EF4 CTP5 define a relationship between the two database tables? (I know this is an unusual scenario, but I am exploring what's possible and what's not with Code-First)

• Entity Framework 4 mapping fragment error when adding new entity scalar

  - by Jason Morse

  I have an Entity Framework 4 model-first design. I create a first draft of my model in the designer and all was well. I compiled, generated database, etc. Later on I tried to add a string scalar (Nullable = true) to one of my existing entities and I keep getting this type of error when I compile: Error 3004: Problem in mapping fragments starting at line 569: No mapping specified for properties MyEntity.MyValue in Set MyEntities. An Entity with Key (PK) will not round-trip when: Entity is type [MyEntities.MyEntity] I keep having to manually open the EDMX file and correct the XML whenever I add scalars. Ideas on what's going on?

• System.AccessViolationException when using TPT inheritance in Entity Framework CTP5

  - by Ben

  Hi, I'm using TPT inheritance in EF CTP5 with SQL CE 4. I have an abstract base class "Widget" with common properties like "Title". I can successfully save concrete Widget implementations e.g. "TwitterWidget". However, I have a problem retrieving all widgets (or rather ALL widget implementations). My repository exposes the following: public IQueryable<Widget> GetAll(); This effectively returns the IDbSet from the DbContext. The following queries work fine: repo.GetAll().ToList(); repo.GetAll().Where(w => w.Title == "Test").ToList(); repo.GetAll().SingleOrDefault(w => w.Title == "Test"); repo.GetAll().Where(w => w.Title == "Test").OrderBy(x => x.Title).ToList(); However, if I write the following query: repo.GetAll().OrderBy(w => w.Title); I get the following error: Test 'PlanetCloud.Portfolio.Tests.Data.PersistenceTestFixture.Can_get_widgets' failed: System.AccessViolationException : Attempted to read or write protected memory. This is often an indication that other memory is corrupt. at System.Data.SqlServerCe.NativeMethodsHelper.GetValues(IntPtr pSeCursor, Int32 seGetColumn, IntPtr prgBinding, Int32 cDbBinding, IntPtr pData, IntPtr pError) at System.Data.SqlServerCe.NativeMethods.GetValues(IntPtr pSeCursor, Int32 seGetColumn, IntPtr prgBinding, Int32 cDbBinding, IntPtr pData, IntPtr pError) at System.Data.SqlServerCe.SqlCeDataReader.FetchValue(Int32 index) at System.Data.SqlServerCe.SqlCeDataReader.IsDBNull(Int32 ordinal) at lambda_method(Closure , Shaper ) at System.Data.Common.Internal.Materialization.Shaper.HandleEntityAppendOnly[TEntity](Func`2 constructEntityDelegate, EntityKey entityKey, EntitySet entitySet) at lambda_method(Closure , Shaper ) at System.Data.Common.Internal.Materialization.Coordinator`1.ReadNextElement(Shaper shaper) at System.Data.Common.Internal.Materialization.Shaper`1.SimpleEnumerator.MoveNext() at System.Collections.Generic.List`1..ctor(IEnumerable`1 collection) at System.Linq.Enumerable.ToList[TSource](IEnumerable`1 source) However, I can execute the following query without problems: var widgets = repo.GetAll().OfType<Widget>().OrderBy(w => w.Title).ToList(); So if I specify the type as the base class prior to my orderby clause it works. The question is why?

• Add Or Condition to Entity in Entity Framework

  - by Blakewell

  Can you add an "Or" condition to an entity in the entity framework? For example something like: Property1 == (1 or 2 or 3) The message I get when putting the value of "1 || 2 || 3" or "1,2,3" or "1 or 2 or 3" returns this message: condition is not compatible with the type of the member

• Databinding to an Entity Framework in WPF

  - by King Chan

  Is it good to use databinding to Entity Framework's Entity in WPF? I created a singleton entity framework context: To have only one connection and it won't open and close all the time. So I can pass the Entity around to any class, and can modify the Entity and make changes to the database. All ViewModels getting the entity out from the same Context and databinding to the View saves me time from mapping new object, but now I imagine there is problem in not using the newest Context: A ViewModel databinding to a Entity, then someone else updated the data. The ViewModel will still display the old data, because the Context is never being dispose to refresh. I always create new Context and then dispose of it. If I want to pass the Entity around, then there will be conflicts between Context and Entity. What is the suggested way of doing this ?

• Apps crashing with EXC_BAD_ACCESS when changing to a custom keyboard layout

  - by Adam Lindberg

  I have a custom layout installed (svdvorak_mac6.keylayout). After a reboot another keyboard layout was selected, so I selected my usual one instead. This lead to a lot of apps suddenly starting to crash (Chrome, Skype, Adium etc). I can change to any other built in layout for OS X, but as soon as I choose one custom installed one (either form ~/Library/Keyboard Layouts/ or from /Library/Keyboard Layouts/) the apps crash. The only thing I can remember that I did before the reboot was to install Google's video chat plugin for the browser. Here's the crash report from Adium: Process: Adium [372] Path: /Applications/Adium.app/Contents/MacOS/Adium Identifier: com.adiumX.adiumX Version: 1.4.1 (1.4.1) Code Type: X86 (Native) Parent Process: launchd [182] Date/Time: 2010-12-22 22:39:47.833 +0100 OS Version: Mac OS X 10.6.5 (10H574) Report Version: 6 Interval Since Last Report: 257401 sec Crashes Since Last Report: 39 Per-App Interval Since Last Report: 1178959 sec Per-App Crashes Since Last Report: 8 Anonymous UUID: 7CBACDEB-FBAF-4CD5-9C15-7AEA8AC4B5EF Exception Type: EXC_BAD_ACCESS (SIGBUS) Exception Codes: KERN_PROTECTION_FAILURE at 0x0000000000000000 Crashed Thread: 0 Dispatch queue: com.apple.main-thread Thread 0 Crashed: Dispatch queue: com.apple.main-thread 0 com.apple.HIToolbox 0x99722b6d islGetInputSourceProperty + 1107 1 com.apple.HIToolbox 0x9972262c TSMGetInputSourceProperty + 526 2 com.apple.HIToolbox 0x9972787a _ISSendWindowServerKeyboardLayoutUpdate + 412 3 com.apple.HIToolbox 0x9972622b _TSMSetInputSourceSelected + 1429 4 com.apple.HIToolbox 0x99980209 TSMMessagePortCallBack + 574 5 com.apple.CoreFoundation 0x9226840c __CFMessagePortPerform + 540 6 com.apple.CoreFoundation 0x921d34db __CFRunLoopRun + 6523 7 com.apple.CoreFoundation 0x921d1464 CFRunLoopRunSpecific + 452 8 com.apple.CoreFoundation 0x921d1291 CFRunLoopRunInMode + 97 9 com.apple.HIToolbox 0x99717f58 RunCurrentEventLoopInMode + 392 10 com.apple.HIToolbox 0x99717d0f ReceiveNextEventCommon + 354 11 com.apple.HIToolbox 0x99717b94 BlockUntilNextEventMatchingListInMode + 81 12 com.apple.AppKit 0x9189478d _DPSNextEvent + 847 13 com.apple.AppKit 0x91893fce -[NSApplication nextEventMatchingMask:untilDate:inMode:dequeue:] + 156 14 com.apple.AppKit 0x91856247 -[NSApplication run] + 821 15 com.apple.AppKit 0x9184e2d9 NSApplicationMain + 574 16 com.adiumX.adiumX 0x0000322e 0x1000 + 8750 Thread 1: Dispatch queue: com.apple.libdispatch-manager 0 libSystem.B.dylib 0x968f5982 kevent + 10 1 libSystem.B.dylib 0x968f609c _dispatch_mgr_invoke + 215 2 libSystem.B.dylib 0x968f5559 _dispatch_queue_invoke + 163 3 libSystem.B.dylib 0x968f52fe _dispatch_worker_thread2 + 240 4 libSystem.B.dylib 0x968f4d81 _pthread_wqthread + 390 5 libSystem.B.dylib 0x968f4bc6 start_wqthread + 30 Thread 2: 0 libSystem.B.dylib 0x968f4a12 __workq_kernreturn + 10 1 libSystem.B.dylib 0x968f4fa8 _pthread_wqthread + 941 2 libSystem.B.dylib 0x968f4bc6 start_wqthread + 30 Thread 3: com.apple.CFSocket.private 0 libSystem.B.dylib 0x968ee0c6 select$DARWIN_EXTSN + 10 1 com.apple.CoreFoundation 0x92211c83 __CFSocketManager + 1091 2 libSystem.B.dylib 0x968fc85d _pthread_start + 345 3 libSystem.B.dylib 0x968fc6e2 thread_start + 34 Thread 4: 0 libSystem.B.dylib 0x968f4a12 __workq_kernreturn + 10 1 libSystem.B.dylib 0x968f4fa8 _pthread_wqthread + 941 2 libSystem.B.dylib 0x968f4bc6 start_wqthread + 30 Thread 5: 0 libSystem.B.dylib 0x968cf15a semaphore_timedwait_signal_trap + 10 1 libSystem.B.dylib 0x968fcce5 _pthread_cond_wait + 1066 2 libSystem.B.dylib 0x9692bac8 pthread_cond_timedwait_relative_np + 47 3 ...apple.AddressBook.framework 0x9310043f -[ABRemoteImageLoader workLoop] + 283 4 com.apple.Foundation 0x97822bf0 -[NSThread main] + 45 5 com.apple.Foundation 0x97822ba0 __NSThread__main__ + 1499 6 libSystem.B.dylib 0x968fc85d _pthread_start + 345 7 libSystem.B.dylib 0x968fc6e2 thread_start + 34 Thread 6: 0 libSystem.B.dylib 0x968cf0fa mach_msg_trap + 10 1 libSystem.B.dylib 0x968cf867 mach_msg + 68 2 com.apple.CoreFoundation 0x921d237f __CFRunLoopRun + 2079 3 com.apple.CoreFoundation 0x921d1464 CFRunLoopRunSpecific + 452 4 com.apple.CoreFoundation 0x921d1291 CFRunLoopRunInMode + 97 5 com.apple.Foundation 0x9785b7d0 +[NSURLConnection(NSURLConnectionReallyInternal) _resourceLoadLoop:] + 329 6 com.apple.Foundation 0x97822bf0 -[NSThread main] + 45 7 com.apple.Foundation 0x97822ba0 __NSThread__main__ + 1499 8 libSystem.B.dylib 0x968fc85d _pthread_start + 345 9 libSystem.B.dylib 0x968fc6e2 thread_start + 34 Thread 0 crashed with X86 Thread State (32-bit): eax: 0x00000670 ebx: 0x9972272e ecx: 0x00000000 edx: 0x00000002 edi: 0xa0c3b214 esi: 0x00000004 ebp: 0xbfffe6c8 esp: 0xbfffe660 ss: 0x0000001f efl: 0x00010202 eip: 0x99722b6d cs: 0x00000017 ds: 0x0000001f es: 0x0000001f fs: 0x00000000 gs: 0x00000037 cr2: 0x00000000 Binary Images: 0x1000 - 0x1a0ff7 +com.adiumX.adiumX 1.4.1 (1.4.1) <136586E8-F3F5-99ED-DB1F-48C0027686CB> /Applications/Adium.app/Contents/MacOS/Adium 0x1f9000 - 0x23efe7 +AIUtilities ???

• What is an Entity? Why is it called Entity?

  - by rkrauter

  What is the deal with Entities (when talking about the Entity Framework)? From what I understand, it is pretty much an in memory representation of a data store like sql tables. Entities are smart enough to track changes and apply those changes to the data store. Is there anything more to it? Thanks in advance.

• Entity Framework self referencing entity deletion.

  - by Viktor

  Hello. I have a structure of folders like this: Folder1 Folder1.1 Folder1.2 Folder2 Folder2.1 Folder2.1.1 and so on.. The question is how to cascade delete them(i.e. when remove folder2 all children are also deleted). I can't set an ON DELETE action because MSSQL does not allow it. Can you give some suggesions? UPDATE: I wrote this stored proc, can I just leave it or it needs some modifications? SET ANSI_NULLS ON GO SET QUOTED_IDENTIFIER ON GO CREATE PROCEDURE sp_DeleteFoldersRecursive @parent_folder_id int AS BEGIN SET NOCOUNT ON; IF @parent_folder_id = 0 RETURN; CREATE TABLE #temp(fid INT ); DECLARE @Count INT; INSERT INTO #temp(fid) SELECT FolderId FROM Folders WHERE FolderId = @parent_folder_id; SET @Count = @@ROWCOUNT; WHILE @Count > 0 BEGIN INSERT INTO #temp(fid) SELECT FolderId FROM Folders WHERE EXISTS (SELECT FolderId FROM #temp WHERE Folders.ParentId = #temp.fid) AND NOT EXISTS (SELECT FolderId FROM #temp WHERE Folders.FolderId = #temp.fid); SET @Count = @@ROWCOUNT; END DELETE Folders FROM Folders INNER JOIN #temp ON Folders.FolderId = #temp.fid; DROP TABLE #temp; END GO

• Entity Framework version 1- Brief Synopsis and Tips &ndash; Part 1

  - by Rohit Gupta

  To Do Eager loading use Projections (for e.g. from c in context.Contacts select c, c.Addresses)  or use Include Query Builder Methods (Include(“Addresses”)) If there is multi-level hierarchical Data then to eager load all the relationships use Include Query Builder methods like customers.Include("Order.OrderDetail") to include Order and OrderDetail collections or use customers.Include("Order.OrderDetail.Location") to include all Order, OrderDetail and location collections with a single include statement =========================================================================== If the query uses Joins then Include() Query Builder method will be ignored, use Nested Queries instead If the query does projections then Include() Query Builder method will be ignored Use Address.ContactReference.Load() OR Contact.Addresses.Load() if you need to Deferred Load Specific Entity – This will result in extra round trips to the database ObjectQuery<> cannot return anonymous types... it will return a ObjectQuery<DBDataRecord> Only Include method can be added to Linq Query Methods Any Linq Query method can be added to Query Builder methods. If you need to append a Query Builder Method (other than Include) after a LINQ method  then cast the IQueryable<Contact> to ObjectQuery<Contact> and then append the Query Builder method to it =========================================================================== Query Builder methods are Select, Where, Include Methods which use Entity SQL as parameters e.g. "it.StartDate, it.EndDate" When Query Builder methods do projection then they return ObjectQuery<DBDataRecord>, thus to iterate over this collection use contact.Item[“Name”].ToString() When Linq To Entities methods do projection, they return collection of anonymous types --- thus the collection is strongly typed and supports Intellisense EF Object Context can track changes only on Entities, not on Anonymous types. If you use a Defining Query for a EntitySet then the EntitySet becomes readonly since a Defining Query is the same as a View (which is treated as a ReadOnly by default). However if you want to use this EntitySet for insert/update/deletes then we need to map stored procs (as created in the DB) to the insert/update/delete functions of the Entity in the Designer You can use either Execute method or ToList() method to bind data to datasources/bindingsources If you use the Execute Method then remember that you can traverse through the ObjectResult<> collection (returned by Execute) only ONCE. In WPF use ObservableCollection to bind to data sources , for keeping track of changes and letting EF send updates to the DB automatically. Use Extension Methods to add logic to Entities. For e.g. create extension methods for the EntityObject class. Create a method in ObjectContext Partial class and pass the entity as a parameter, then call this method as desired from within each entity. ================================================================ DefiningQueries and Stored Procedures: For Custom Entities, one can use DefiningQuery or Stored Procedures. Thus the Custom Entity Collection will be populated using the DefiningQuery (of the EntitySet) or the Sproc. If you use Sproc to populate the EntityCollection then the query execution is immediate and this execution happens on the Server side and any filters applied will be applied in the Client App. If we use a DefiningQuery then these queries are composable, meaning the filters (if applied to the entityset) will all be sent together as a single query to the DB, returning only filtered results. If the sproc returns results that cannot be mapped to existing entity, then we first create the Entity/EntitySet in the CSDL using Designer, then create a dummy Entity/EntitySet using XML in the SSDL. When creating a EntitySet in the SSDL for this dummy entity, use a TSQL that does not return any results, but does return the relevant columns e.g. select ContactID, FirstName, LastName from dbo.Contact where 1=2 Also insure that the Entity created in the SSDL uses the SQL DataTypes and not .NET DataTypes. If you are unable to open the EDMX file in the designer then note the Errors ... they will give precise info on what is wrong. The Thrid option is to simply create a Native Query in the SSDL using <Function Name="PaymentsforContact" IsComposable="false">   <CommandText>SELECT ActivityId, Activity AS ActivityName, ImagePath, Category FROM dbo.Activities </CommandText></FuncTion> Then map this Function to a existing Entity. This is a quick way to get a custom Entity which is regular Entity with renamed columns or additional columns (which are computed columns). The disadvantage to using this is that It will return all the rows from the Defining query and any filter (if defined) will be applied only at the Client side (after getting all the rows from DB). If you you DefiningQuery instead then we can use that as a Composable Query. The Fourth option (for mapping a READ stored proc results to a non-existent Entity) is to create a View in the Database which returns all the fields that the sproc also returns, then update the Model so that the model contains this View as a Entity. Then map the Read Sproc to this View Entity. The other option would be to simply create the View and remove the sproc altogether. ================================================================ To Execute a SProc that does not return a entity, use a EntityCommand to execute that proc. You cannot call a sproc FunctionImport that does not return Entities From Code, the only way is to use SSDL function calls using EntityCommand.  This changes with EntityFramework Version 4 where you can return Scalar Types, Complex Types, Entities or NonQuery ================================================================ UDF when created as a Function in SSDL, we need to set the Name & IsComposable properties for the Function element. IsComposable is always false for Sprocs, for UDF's set this to true. You cannot call UDF "Function" from within code since you cannot import a UDF Function into the CSDL Model (with Version 1 of EF). only stored procedures can be imported and then mapped to a entity ================================================================ Entity Framework requires properties that are involved in association mappings to be mapped in all of the function mappings for the entity (Insert, Update and Delete). Because Payment has an association to Reservation... hence we need to pass both the paymentId and reservationId to the Delete sproc even though just the paymentId is the PK on the Payment Table. ================================================================ When mapping insert, update and delete procs to a Entity, insure that all the three or none are mapped. Further if you have a base class and derived class in the CSDL, then you must map (ins, upd, del) sprocs to all parent and child entities in the inheritance relationship. Note that this limitation that base and derived entity methods must all must be mapped does not apply when you are mapping Read Stored Procedures.... ================================================================ You can write stored procedures SQL directly into the SSDL by creating a Function element in the SSDL and then once created, you can map this Function to a CSDL Entity directly in the designer during Function Import ================================================================ You can do Entity Splitting such that One Entity maps to multiple tables in the DB. For e.g. the Customer Entity currently derives from Contact Entity...in addition it also references the ContactPersonalInfo Entity. One can copy all properties from the ContactPersonalInfo Entity into the Customer Entity and then Delete the CustomerPersonalInfo entity, finall one needs to map the copied properties to the ContactPersonalInfo Table in Table Mapping (by adding another table (ContactPersonalInfo) to the Table Mapping... this is called Entity Splitting. Thus now when you insert a Customer record, it will automatically create SQL to insert records into the Contact, Customers and ContactPersonalInfo tables even though you have a Single Entity called Customer in the CSDL =================================================================== There is Table by Type Inheritance where another EDM Entity can derive from another EDM entity and absorb the inherted entities properties, for example in the Break Away Geek Adventures EDM, the Customer entity derives (inherits) from the Contact Entity and absorbs all the properties of Contact entity. Thus when you create a Customer Entity in Code and then call context.SaveChanges the Object Context will first create the TSQL to insert into the Contact Table followed by a TSQL to insert into the Customer table =================================================================== Then there is the Table per Hierarchy Inheritance..... where different types are created based on a condition (similar applying a condition to filter a Entity to contain filtered records)... the diference being that the filter condition populates a new Entity Type (derived from the base Entity). In the BreakAway sample the example is Lodging Entity which is a Abstract Entity and Then Resort and NonResort Entities which derive from Lodging Entity and records are filtered based on the value of the Resort Boolean field =================================================================== Then there is Table per Concrete Type Hierarchy where we create a concrete Entity for each table in the database. In the BreakAway sample there is a entity for the Reservation table and another Entity for the OldReservation table even though both the table contain the same number of fields. The OldReservation Entity can then inherit from the Reservation Entity and configure the OldReservation Entity to remove all Scalar Properties from the Entity (since it inherits the properties from Reservation and filters based on ReservationDate field) =================================================================== Complex Types (Complex Properties) Entities in EF can also contain Complex Properties (in addition to Scalar Properties) and these Complex Properties reference a ComplexType (not a EntityType) DropdownList, ListBox, RadioButtonList, CheckboxList, Bulletedlist are examples of List server controls (not data bound controls) these controls cannot use Complex properties during databinding, they need Scalar Properties. So if a Entity contains Complex properties and you need to bind those to list server controls then use projections to return Scalar properties and bind them to the control (the disadvantage is that projected collections are not tracked by the Object Context and hence cannot persist changes to the projected collections bound to controls) ObjectDataSource and EntityDataSource do account for Complex properties and one can bind entities with Complex Properties to Data Source controls and they will be tracked for changes... with no additional plumbing needed to persist changes to these collections bound to controls So DataBound controls like GridView, FormView need to use EntityDataSource or ObjectDataSource as a datasource for entities that contain Complex properties so that changes to the datasource done using the GridView can be persisted to the DB (enabling the controls for updates)....if you cannot use the EntityDataSource you need to flatten the ComplexType Properties using projections With EF Version 4 ComplexTypes are supported by the Designer and can add/remove/compose Complex Types directly using the Designer =================================================================== Conditional Mapping ... is like Table per Hierarchy Inheritance where Entities inherit from a base class and then used conditions to populate the EntitySet (called conditional Mapping). Conditional Mapping has limitations since you can only use =, is null and IS NOT NULL Conditions to do conditional mapping. If you need more operators for filtering/mapping conditionally then use QueryView(or possibly Defining Query) to create a readonly entity. QueryView are readonly by default... the EntitySet created by the QueryView is enabled for change tracking by the ObjectContext, however the ObjectContext cannot create insert/update/delete TSQL statements for these Entities when SaveChanges is called since it is QueryView. One way to get around this limitation is to map stored procedures for the insert/update/delete operations in the Designer. =================================================================== Difference between QueryView and Defining Query : QueryView is defined in the (MSL) Mapping File/section of the EDM XML, whereas the DefiningQuery is defined in the store schema (SSDL). QueryView is written using Entity SQL and is this database agnostic and can be used against any database/Data Layer. DefiningQuery is written using Database Lanaguage i.e. TSQL or PSQL thus you have more control =================================================================== Performance: Lazy loading is deferred loading done automatically. lazy loading is supported with EF version4 and is on by default. If you need to turn it off then use context.ContextOptions.lazyLoadingEnabled = false To improve Performance consider PreCompiling the ObjectQuery using the CompiledQuery.Compile method

• Using unordered_multimap as entity and component storage

  - by natebot13

  The Setup I've made a few games (more like animations) using the Object Oriented method with base classes for objects that extend them, and objects that extend those, and found I couldn't wrap my head around expanding that system to larger game ideas. So I did some research and discovered the Entity-Component system of designing games. I really like the idea, and thoroughly understood the usefulness of it after reading Byte54's perfect answer here: Role of systems in entity systems architecture. With that said, I have decided to create my current game idea using the described Entity-Component system. Having basic knowledge of C++, and SFML, I would like to implement the backbone of this entity component system using an unordered_multimap without classes for the entities themselves. Here's the idea: An unordered_mulitmap stores entity IDs as the lookup term, while the value is an inherited Component object. Examlpe: ____________________________ |ID |Component | ---------------------------- |0 |Movable | |0 |Accelable | |0 |Renderable | |1 |Movable | |1 |Renderable | |2 |Renderable | ---------------------------- So, according to this map of objects, the entity with ID 0 has three components: Movable, Accelable, and Renderable. These component objects store the entity specific data, such as the location, the acceleration, and render flags. The entity is simply and ID, with the components attached to that ID describing its attributes. Problem I want to store the component objects within the map, allowing the map have full ownership of the components. The problem I'm having, is I don't quite understand enough about pointers, shared pointers, and references in order to get that set up. How can I go about initializing these components, with their various member variables, within the unordered_multimap? Can the base component class take on the member variables of its child classes, when defining the map as unordered_multimap<int, component>? Requirements I need a system to be able to grab an entity, with all of its' attached components, and access members from the components in order to do the necessary calculations and reassignments for position, velocity, etc. Need a clarification? Post a comment with your concerns and I will gladly edit or comment back! Thanks in advance! natebot13

• Entity Framework won't SaveChanges on new entity with two-level relationship

  - by Tim Rourke

  I'm building an ASP.NET MVC site using the ADO.NET Entity Framework. I have an entity model that includes these entities, associated by foreign keys: Report(ID, Date, Heading, Report_Type_ID, etc.) SubReport(ID, ReportText, etc.) - one-to-one relationship with Report. ReportSource(ID, Name, Description) - one-to-many relationship with Sub_Report. ReportSourceType(ID, Name, Description) - one-to-many relationship with ReportSource. Contact (ID, Name, Address, etc.) - one-to-one relationship with Report_Source. There is a Create.aspx page for each type of SubReport. The post event method returns a new Sub_Report entity. Before, in my post method, I followed this process: Set the properties for a new Report entity from the page's fields. Set the SubReport entity's specific properties from the page's fields. Set the SubReport entity's Report to the new Report entity created in 1. Given an ID provided by the page, look up the ReportSource and set the Sub_Report entity's ReportSource to the found entity. SaveChanges. This workflow succeeded just fine for a couple of weeks. Then last week something changed and it doesn't work any more. Now instead of the save operation, I get this Exception: UpdateException: "Entities in 'DIR2_5Entities.ReportSourceSet' participate in the 'FK_ReportSources_ReportSourceTypes' relationship. 0 related 'ReportSourceTypes' were found. 1 'Report_Source_Types' is expected." The debug visualizer shows the following: The SubReport's ReportSource is set and loaded, and all of its properties are correct. The Report_Source has a valid ReportSourceType entity attached. In SQL Profiler the prepared SQL statement looks OK. Can anybody point me to what obvious thing I'm missing? TIA Notes: The Report and SubReport are always new entities in this case. The Report entity contains properties common to many types of reports and is used for generic queries. SubReports are specific reports with extra parameters varying by type. There is actually a different entity set for each type of SubReport, but this question applies to all of them, so I use SubReport as a simplified example.

• State / Screen management in Entity Component Systems

  - by David Lively

  My entity/component system is happily humming along and, despite some performance concerns I initially had, everything is working fine. However, I've realized that I missed a crucial point when starting this thing: how do you handle different screens? At the moment, I have a GameManager class which owns a component manager and entity manager. When I create an entity, the entity manager assigns it an ID and makes sure it's tracked. When I modify the components that are assigned to an entity. an UpdateEntity method is called, which alerts each of the systems that they may need to add or remove the entity from their respective entity lists. A problem with this is that the collection of entities operated on by each system is determined solely by the individual Systems, typically based on a "required component" filter. (An entity has to have a Renderable component to be rendered, for instance.) In this situation, I can't just keep collections of entities per screen and only Update/Draw those collections. They'd have to either be added and removed depending on their applicability to the current screen, which would cause their associated components to be removed, or enable/disable entities in a group per screen to hide what's not supposed to be visible. These approaches seem like really, really crappy kludges. What's a good way to handle this? A pretty straightforward way that comes to mind is to create a separate GameManager (which in my implementation owns all of the systems, entities, etc.) per screen, which means that everything outside of the device context would be duplicated. That's bothersome because some things are always visible, or I might want to continue to display the game under a translucent menu window. Another option would be to add a "layer" key to the GameManager class, which could be checked against a displayable layer stack held by the game manager. *System.Draw() would be called for each active layer, in the required order as determined by the stack. When the systems request an iterator for their respective entity collections, it would be pre-filtered to a (cached) set of those entities that participate in the active layer. Those collections could be updated from the same UpdateEntity event that's already used to maintain each system's entity collections. Still, kinda feels like a hack. If I've coded myself into a corner, feel free to throw tomatoes as long as they're labeled with a helpful suggestion. Hooray for learning curves.

• Many sources of movement in an entity system

  - by Sticky

  I'm fairly new to the idea of entity systems, having read a bunch of stuff (most usefully, this great blog and this answer). Though I'm having a little trouble understanding how something as simple as being able to manipualate the position of an object by an undefined number of sources. That is, I have my entity, which has a position component. I then have some event in the game which tells this entity to move a given distance, in a given time. These events can happen at any time, and will have different values for position and time. The result is that they'd be compounded together. In a traditional OO solution, I'd have some sort of MoveBy class, that contains the distance/time, and an array of those inside my game object class. Each frame, I'd iterate through all the MoveBy, and apply it to the position. If a MoveBy has reached its finish time, remove it from the array. With the entity system, I'm a little confused as how I should replicate this sort of behavior. If there were just one of these at a time, instead of being able to compound them together, it'd be fairly straightforward (I believe) and look something like this: PositionComponent containing x, y MoveByComponent containing x, y, time Entity which has both a PositionComponent and a MoveByComponent MoveBySystem that looks for an entity with both these components, and adds the value of MoveByComponent to the PositionComponent. When the time is reached, it removes the component from that entity. I'm a bit confused as to how I'd do the same thing with many move by's. My initial thoughts are that I would have: PositionComponent, MoveByComponent the same as above MoveByCollectionComponent which contains an array of MoveByComponents MoveByCollectionSystem that looks for an entity with a PositionComponent and a MoveByCollectionComponent, iterating through the MoveByComponents inside it, applying/removing as necessary. I guess this is a more general problem, of having many of the same component, and wanting a corresponding system to act on each one. My entities contain their components inside a hash of component type - component, so strictly have only 1 component of a particular type per entity. Is this the right way to be looking at this? Should an entity only ever have one component of a given type at all times?

• What does Symfony Framework offer that Zend Framework does not?

  - by Fatmuemoo

  I have professionally working with Zend Framework for about a year. No major complaints. With some modifications, it has done a good job. I'm beginning to work on a side project where I want to heavily rely on MongoDb and Doctrine. I thought it might be a good idea to broaden my horizons and learn another enterprise level framework. There seems to be a lot a buzz about Symfony. After quickly looking over the site and documentation, I must say I came away pretty underwhelmed. I'm woundering what, if anything, Symfony has to offer that Zend doesn't? What would the advantage be in choosing Symfony?

• Organizing an entity system with external component managers?

  - by Gustav

  I'm designing a game engine for a top-down multiplayer 2D shooter game, which I want to be reasonably reuseable for other top-down shooter games. At the moment I'm thinking about how something like an entity system in it should be designed. First I thought about this: I have a class called EntityManager. It should implement a method called Update and another one called Draw. The reason for me separating Logic and Rendering is because then I can omit the Draw method if running a standalone server. EntityManager owns a list of objects of type BaseEntity. Each entity owns a list of components such as EntityModel (the drawable representation of an entity), EntityNetworkInterface, and EntityPhysicalBody. EntityManager also owns a list of component managers like EntityRenderManager, EntityNetworkManager and EntityPhysicsManager. Each component manager keeps references to the entity components. There are various reasons for moving this code out of the entity's own class and do it collectively instead. For example, I'm using an external physics library, Box2D, for the game. In Box2D, you first add the bodies and shapes to a world (owned by the EntityPhysicsManager in this case) and add collision callbacks (which would be dispatched to the entity object itself in my system). Then you run a function which simulates everything in the system. I find it hard to find a better solution to do this than doing it in an external component manager like this. Entity creation is done like this: EntityManager implements the method RegisterEntity(entityClass, factory) which registers how to create an entity if that class. It also implements the method CreateEntity(entityClass) which would return an object of type BaseEntity. Well now comes my problem: How would the reference to a component be registered to the component managers? I have no idea how I would reference the component managers from a factory/closure.

• sync Framework for Compact Framework

  - by CF_Maintainer

  Has anyone got sync framework to work on a mobile device as a sync mechanism in place of RDA or Merge replication? If yes, could you point me to any resources available. If one was to start a green field compact framework based application, what would one use as the sync mechanism (sync framework/RDA/Merge replication/any other...)? Thanks

• What is .Net Framework 4 extended?

  - by Click Ok

  For testing purposes, I installed .Net Framework 4 Client Profile. My tests ended and I was to uninstall it, in order to install .Net Framework 4 full. The uninstaller told me to uninstall .Net Framework 4 extended first. I've already found it and uninstalled, but the question remains: What is .Net Framework 4 extended?

• Entity Relationship Multiple 1:1's

  - by Evan

  I have an application where I have a generic object (table) called Hull. Each hull in the table is unique. I have another object that has three hulls, but they are specifically the Port_Hull, Center_Hull and Starboard_Hull. Rather than create a One to Many relationship, I was trying to create a one to one relationship for each one, but this results in numerous errors unless I make the relationship from Hull to Vessel one to many (which it is not). Any idea how I go about this, or should I abandon the concept and make the vessel to hull relationship one to many and deal with lists that always have three entries? p.s. Using uniqueidentifiers as many users can be adding records while disconnected. Hull Table HullID uniqueidentifier (primary key) plus bunch of hull data fields Vessel Table VesselID uniqueidentifier (primary key) MainHullID uniqueidentifier (tried as key and non-key) PortHullID uniqueidentifier StarboardHullID uniqueidentifier plus bunch of Vessel data fields

• Prevent Custom Entity being deleted from Entity Framework during Update Model Wizard

  - by rbg

  In Entity Framework v1 If you create a Custom Entity to map it to a Stored Procedure during FunctionImport and then Select "Update Model from Database" the Update Model Wizard removes the Custom Entity (as added Manually in the SSDL XML prior to functionImport) from the SSDL. Does anyone know if this limitation has been dealt with Entity Framework v4? I mean is there a way to prevent the Wizard from removing the Custom Entity from the Storage Schema (SSDL) during Model Update from Database????

• Hibernate is persisting entity during flush when the entity has not changed

  - by Preston

  I'm having a problem where the entity manger is persisting an entity that I don't think has changed during the flush. I know the following code is the problem because if I comment it out the entity doesn't persist. In this code all I'm doing is loading the entity and calling some getters. Query qry = em.createNamedQuery("Clients.findByClientID"); qry.setParameter("clientID", clientID); Clients client = (Clients) qry.getSingleResult(); results.setFname(client.getFirstName()); results.setLname(client.getLastName()); ... return results; Later in a different method I do another namedQuery which causes the entity manger to flush. For some reason the client loaded above is persisted. The reason this is a problem is because in the middle of all this, there is some old code that is making some straight JDBC changes to the client. When the entity manger persists the changes made by the straight JDBC are lost. The theory we have at moment is that the entity manger is comparing the entity to the underlying record, sees that it's different, then persists it. Can someone explain or confirm the behavior we're seeing?

• Entity System with C++

  - by Dono

  I'm working on a game engine using the Entity System and I have some questions. How I see Entity System : Components : A class with attributs, set and get. Sprite Physicbody SpaceShip ... System : A class with a list of components. (Component logic) EntityManager Renderer Input Camera ... Entity : Just a empty class with a list of components. What I've done : Currently, I've got a program who allow me to do that : // Create a new entity/ Entity* entity = game.createEntity(); // Add some components. entity->addComponent( new TransformableComponent() ) ->setPosition( 15, 50 ) ->setRotation( 90 ) ->addComponent( new PhysicComponent() ) ->setMass( 70 ) ->addComponent( new SpriteComponent() ) ->setTexture( "name.png" ) ->addToSystem( new RendererSystem() ); My questions Did the system stock a list of components or a list of entities ? In the case where I stock a list of entities, I need to get the component of this entities on each frame, that's probably heavy isn't it ?

• Entity framework, adding custom entity to diagram

  - by molgan

  Hello I'm using the entity framework that comes with 3.5sp1, and I'm trying to add a custom entity that I will propulate with searchresults from a stored procedure. But I have problems with the designer....... when I pick "Add + Entity" and give it a name, and hit save, the whole diagram stops working...... blah entities namespace could not be found..... all the other entities have lost its reference or summet. Works when I add a "table" to it that exists in database. But when custom it screws everything up. How should I fix this? I've imported the function, I just need to add an entity for it... I've read http://blogs.microsoft.co.il/blogs/gilf/archive/2009/03/13/mapping-stored-procedure-results-to-a-custom-entity-in-entity-framework.aspx but I cant get to step 3 since of all the errors when saving on step 2. /M
