  • MVC 3, View Model for user registration process. Password validation not working properly

    - by sec_goat
    I am trying to create a user registration page using MVC 3, so that I can better understand the process of how it works, what's going on behind the scenes etc. I am running into some issues when trying to use [Compare] to check to see that the user entered the same password twice. I tried adding the ComparePassword field to my user model first, and found that would not work the way I wanted as I did not have the field in the database, so the obvious answer was to create a View Model using the same information including the ComparePassword field. So I now have created a User model and a RegistrationViewModel, however it appears that the [Compare] on the password is not returning anything, for instance no matter what I put in the two boxes, when I click create it gives no error, which seems to me to mean it was successfully validated. I am not sure what I am doing or not doing to make this work properly. I have tried updating the jQuery.Validate to the newest version as there were some bugs reported in older version, this has not helped my efforts. Below is a wall of code, that is what I am working with. } public class RegistrationViewModel { [Required] [StringLength(15, MinimumLength = 3)] [Display(Name = "User Name")] [RegularExpression(@"(\S)+", ErrorMessage = " White Space is not allowed in User Names")] [ScaffoldColumn(false)] public String Username { get; set; } [Required] [StringLength(15, MinimumLength = 3)] [Display(Name = "First Name")] public String firstName { get; set; } [Required] [StringLength(15, MinimumLength = 3)] [Display(Name = "Last Name")] public String lastName { get; set; } [Required] [Display(Name = "Email")] public String email { get; set; } [Required] [Display(Name = "Password")] [DataType(DataType.Password)] public String password { get; set; } [Required] [DataType(DataType.Password)] [Display(Name = "Re-enter Password")] [Compare("Password", ErrorMessage = "Passwords do not match.")] public String comparePassword { get; set; } }

  • Create bullet physics rigid body along the vertices of a blender model

    - by Krishnabhadra
    I am working on my first 3D game, for iphone, and I am using Blender to create models, Cocos3D game engine and Bullet for physics simulation. I am trying to learn the use of physics engine. What I have done I have created a small model in blender which contains a Cube (default blender cube) at the origin and a UVSphere hovering exactly on top of this cube (without touching the cube) I saved the file to get MyModel.blend. Then I used File -> Export -> PVRGeoPOD (.pod/.h/.cpp) in Blender to export the model to .pod format to use along with Cocos3D. In the coding side, I added necessary bullet files to my Cocos3D template project in XCode. I am also using a bullet objective C wrapper. -(void) initializeScene { _physicsWorld = [[CC3PhysicsWorld alloc] init]; [_physicsWorld setGravity:0 y:-9.8 z:0]; /*Setup camera, lamp etc.*/ .......... ........... /*Add models created in blender to scene*/ [self addContentFromPODFile: @"MyModel.pod"]; /*Create OpenGL ES buffers*/ [self createGLBuffers]; /*get models*/ CC3MeshNode* cubeNode = (CC3MeshNode*)[self getNodeNamed:@"Cube"]; CC3MeshNode* sphereNode = (CC3MeshNode*)[self getNodeNamed:@"Sphere"]; /*Those boring grey colors..*/ [cubeNode setColor:ccc3(255, 255, 0)]; [sphereNode setColor:ccc3(255, 0, 0)]; float *cVertexData = (float*)((CC3VertexArrayMesh*)cubeNode.mesh).vertexLocations.vertices; int cVertexCount = (CC3VertexArrayMesh*)cubeNode.mesh).vertexLocations.vertexCount; btTriangleMesh* cTriangleMesh = new btTriangleMesh(); // for (int i = 0; i < cVertexCount * 3; i+=3) { // printf("\n%f", cVertexData[i]); // printf("\n%f", cVertexData[i+1]); // printf("\n%f", cVertexData[i+2]); // } /*Trying to create a triangle mesh that curresponds the cube in 3D space.*/ int offset = 0; for (int i = 0; i < (cVertexCount / 3); i++){ unsigned int index1 = offset; unsigned int index2 = offset+6; unsigned int index3 = offset+12; cTriangleMesh->addTriangle( btVector3(cVertexData[index1], cVertexData[index1+1], cVertexData[index1+2] ), btVector3(cVertexData[index2], cVertexData[index2+1], cVertexData[index2+2] ), btVector3(cVertexData[index3], cVertexData[index3+1], cVertexData[index3+2] )); offset += 18; } [self releaseRedundantData]; /*Create a collision shape from triangle mesh*/ btBvhTriangleMeshShape* cTriMeshShape = new btBvhTriangleMeshShape(cTriangleMesh,true); btCollisionShape *sphereShape = new btSphereShape(1); /*Create physics objects*/ gTriMeshObject = [_physicsWorld createPhysicsObjectTrimesh:cubeNode shape:cTriMeshShape mass:0 restitution:1.0 position:cubeNode.location]; sphereObject = [_physicsWorld createPhysicsObject:sphereNode shape:sphereShape mass:1 restitution:0.1 position:sphereNode.location]; sphereObject.rigidBody->setDamping(0.1,0.8); } When I run the sphere and cube shows up fine. I expect the sphere object to fall directly on top of the cube, since I have given it a mass of 1 and the physics world gravity is given as -9.8 in y direction. But What is happening the spere rotates around cube three or times and then just jumps out of the scene. Then I know I have some basic misunderstanding about the whole process. So my question is, how can I create a physics collision shape which corresponds to the shape of a particular mesh model. I may need complex shapes than cube and sphere, but before going into them I want to understand the concepts.

  • Models, collections...and then what? Processes?

    - by Dan
    I'm a LAMP-stack dev who's been more on the JavaScript side the last few years and really enjoying the Model + Collection approach to data entities that BackboneJS, etc. uses. It's helped me organize my code in such a way that it is extremely portable, keeping all my properties and methods in the scope (model, collection, etc.) in which they apply. One thing that keeps bugging me though is how to organize the next level up, the 'process layer' as you might call it, that can potentially operate on instances of either models or collections or whatever else. Where should methods like find() (which returns a collection) and create() (which returns a model) reside? I know some people would put a create() in the Collection prototype, but while a collection operates on models I don't think it's exactly right to create them. And while a find() would return a collection I don't think it correct to have that action within the collection prototype itself (it should be a layer up). Can anyone offer some examples of any patterns that employ some kind of OOP-friendly 'process' layer? I'm sorry if this is a fairly well-known discussion but I'm afraid I can't seem to find the terminology to search for.

  • Using separate model methods to manage transactions

    - by DCrystal
    If i’ve got 2(or more) model methods which do (for example, in billing system) enrolling/withdrawing, and one controller’s method that calls 2(or more) of these model methods. Is it a good way(maybe, any suggestions how to do it better) to write/use 2model methods like these: public function start_transaction(){ $this->db->trans_start(); } public function end_transaction(){ $this->db->trans_complete(); } And call in controller’s method: public function smth(){ //something $this->model->start_transaction(); $this->model->enroll(); //something else $this->model->withdraw(); $this->model->end_transaction(); } Will transaction be reversed, if model's withdraw() method fails? Thanks.

  • ASP.Net MVC 2: How to keep values in the model between posts

    - by Andreas
    I have an edit view that is displaying some model properties as plain text and other model properties as input fields. My problem is that the model properties displayed as plain text are null when the model is returned to the view after a validation error. How do I retain the model values when I don't have input fields for all properties? What is best practice? My first thought is to keep the values of these properties in hidden input elements. <%= Html.HiddenFor(model => model.CustomerName) %> Is this considered a correct solution? Thanks Andreas

  • Entity Framework 4 Hiding Underlying Resolver Tables when model is generated from database

    - by grrrrrrrrrrrrr
    When creating an entity framework model from scratch it is possible to specify a Many to Many relationship in the model. e.g Entity1 * ----- * Entity2 When a database is then generated from this, a resolver table is then created automatically between the two entities, this is hidden in the code model, allowing direct access to each of the entities via properties. e.g. Entity1 ----* ResolverEntity *----- Entity2 My question is, when a model is generated from an existing database, which contains resolver tables, is it possible to create the same effect so the resolver tables do not appear in the generated object model? When I have attempted this, the entity framework appears to create entities in the model for the resolver tables with no obvious way of hiding them in the object model. Thanks.

  • Is passing the Model around in this way considered bad practice?

    - by Theomax
    If I have a view called, for example, ViewDetails that displays user information in labels and has a Model called ViewDetailsModel and if I want to allow the user to click a button to edit some of these details, is it considered bad practice is I pass the entire Model in the markup to a controller method which then assigns the values for another model, using the values stored in the Model that was passed in as a parameter to that action method? If so, should there instead be a service method that gets the data required for the edit view? For example: In the ViewDetails view, the user clicks the edit button which calls an action method in the controller (and passes in the Model object). The action method then uses the data in the Model object to populate another model which will be used for the EditDetails view that will be returned.

  • Gui problem after rewriting to MVC

    - by trevor_nise
    I'm practicing MVC style programming. I have a Mastermind game in a single file, working with no problems (maybe apart of the fact that "Check" button is invisible at start). http://paste.pocoo.org/show/226726/ But when I've rewritten it to model, view, controller files - when I click on empty Pin (that should be updated, and repainted with new color) - noting happens.

  • DirectX9 / HLSL Shader Model 3 - Passing Doubles between Shaders

    - by P. Avery
    I need higher precision on a few values within my vertex and pixel shaders...I'm currently using floats, so I would like to use doubles...I've read that HLSL Model 4 has two functions to convert a double into two unsigned integers and back again( asuint() and asdouble() ). These functions are only supported on HLSL 4 and I am using DirectX 9 which will only compile HLSL Model 3 and below... How can I pass a double between shaders? here is implementation for HLSL 4: struct VS_INPUT { float2 v; }; struct PS_INPUT { uint a; uint b; uint c; uint d; }; PS_INPUT VertexShader( VS_INPUT Input ) { PS_INPUT Output = ( PS_INPUT )0; double2 vPos = mul( Input.v, mWorld ).xy; asuint( vPos.x, Output.a, Output.b ); asuint( vPos.y, Output.c, Output.d ); return Output; } float4 PixelShader( PS_INPUT Input ) { double2 vPos; vPos.x = asdouble( Input.a, Input.b ); vPos.y = asdouble( Input.c, Input.d ); ... return 1; }

  • Oracle Introduces Oracle Communications Data Model to Provide Actionable Insight for Communications

    - by kimberly.billings
    To help communications service providers (CSPs) manage and analyze rapidly growing data volumes cost effectively, Oracle recently introduced the Oracle Communications Data Model (OCDM). With the OCDM, CSPs can achieve rapid time to value by quickly implementing a standards-based enterprise data warehouse that features communications industry-specific reporting, analytics and data mining. The combination of the OCDM, Oracle Exadata and the Oracle Business Intelligence (BI) Foundation represents the most comprehensive data warehouse and BI solution for the communications industry. Hong Kong Broadband Network, the fastest growing and second largest broadband service provider in Hong Kong, enhanced its data warehouse using Oracle Communications Data Model. It went live with OCDM within three months, and has increased its subscriber base by 37 percent in six months and reduced customer churn to less than one percent. Read more about HKBN's use of OCDM.

  • A Model for Planning Your Oracle BPM 10g Migration by Kris Nelson

    - by JuergenKress
    As the Oracle SOA Suite and BPM Suite 12c products enter beta, many of our clients are starting to discuss migrating from the Oracle 10g or prior platforms. With the BPM Suite 11g, Oracle introduced a major change in architecture with a strong focus on integration with SOA and an entirely new technology stack. In addition, there were fresh new UIs and a renewed business focus with an improved Process Composer and features like Adaptive Case Management. While very beneficial to both technology and the business, the fundamental change in architecture does pose clear migration challenges for clients who have made investments in the 10g platform. Some of the key challenges facing 10g customers include: Managing in-process instance migration and running multiple process engines Migration of User Interfaces and other code within the environment that may not be automated Growing or finding technical staff with both 10g and 12c experience Managing migration projects while continuing to move the business forward and meet day-to-day responsibilities As a former practitioner in a mixed 10g/11g shop, I wrestled with many of these challenges as we tried to plan ahead for the migration. Luckily, there is migration tooling on the way from Oracle and several approaches you can use in planning your migration efforts. In addition, you already have a defined and visible process on the current platform, which will be invaluable as you migrate.  A Migration ModelThis model presents several options across a value and investment spectrum. The goal of the AVIO Migration Model is to kick-start discussions within your company and assist in creating a plan of action to take advantage of the new platform. As with all models, this is a framework for discussion and certain processes or situations may not fit. Please contact us if you have specific questions or want to discuss migrations efforts in your situation. Read the complete article here.

  • Is a Model Driven Architecture in Language Oriented Programming (MPS) feasible at this time

    - by Steven Jeuris
    As a side project I am developing some sort of DSL where I describe a data model, and generate desired code files from it. I believe this is called Model Driven Architecture. My partial existing implementation uses C#, CodeDOM, XML and XSLT to do this manually. I discovered there already exist better environments to do this in. The one which fascinated me the most is called MPS, which follows the Language Oriented Programming paradigm. This article, written by a cofounder of JetBrains was a real eye opener for me. I truly believe LOP has a very good chance of becoming the next big programming paradigm once it has broader support. From my short experience with MPS, I noticed it is still mainly Java-oriented. My question is, how feasible is it to generate code files for other (multiple) languages instead of just Java. I don't need full language support from the start, so preferably, I need to be able to implement a language in a agile way. E.g. first support only one type, add access modifiers, ... Perhaps some other (free) environment already provides this out of the box. P.S.: I find it important to have a lot of control over the naming conventions and such of the generated code. This is one of the reasons why I started my own implementation.

  • Camera Collision inside the room model

    - by sanddy
    I am having a problem in Calculating the camera collision for my Room model which consists of sofa, tables and other models. The users shall be moving the camera front, back, rotating so i need to make sure that the camera does not collide with any of the models with in the room. I have treated all my models inside the room by BoundingBox[] and the camera by BoundingSphere. So, far i have implemented collision by looking into the tutorial from http://www.toymaker.info/Games/XNA/html/xna_model_collisions.html which was great. But, I guess the problem lies in the Transformation part. I debugged and found some points to be at Vector(-XXX,-XXX,-XXX) where X is digit. Also i found my radius of some models where too large(in thousand, i just looked into its radius value before converting to BoundingBox). Do I need to scale the model for collision??? Below are my code:- On My LoadContent(): Matrix[] transforms = new Matrix[myModel.Bones.Count]; myModel.CopyAbsoluteBoneTransformsTo(transforms); int index = 0; box = new List<BoundingBox>(); BoundingBox worldModel = Utility.CalculateBoundingBox(myModel); foreach (ModelMesh mesh in myModel.Meshes) { Vector3[] obb = new Vector3[8]; worldModel.GetCorners(obb); Vector3[] asdf = (Vector3[])obb.Clone(); Vector3.Transform(obb, ref transforms[mesh.ParentBone.Index], obb); BoundingBox worldBox = BoundingBox.CreateFromPoints(obb); box.Add(worldBox); index++; } On CameraPosition Update: BoundingSphere bs = new BoundingSphere(this.cameraPos, 5.0f); if (RoomWalkthrough.Utility.CheckCollision(bs, bb)) { // Do Something } Please Help.

  • Dynamic model interactions

    - by Richard
    I am just curious as to how in many games (namely games like arkham asylum/city, manhunt, hitman) do they make it so that your character can "grab" a character in front of you and do stuff to them. I know this may sound very confusing but for an example go to youtube and search "hitman executions", and the first video is an example of what i'm asking. Basically I'm wondering how they make your model dynamically interact with whatever other model you come across, so in hitman when you come up behind some one with the fibre wire you strangle the other character or if you have the anesthetic you come up behind some person and put your hand over there mouth while they struggle and slowly go to the floor where you lay them down. I am confused as to whether it was animated to use two models using specific bone/skeletal identifiers, if it is just two completely separate animations that are played at the correct time to make it look like they are actually interacting or something else all together. I am not an animator so i assume most of what i just said is not right but i hope that some one can understand what i mean and provide an answer. PS) I am a programmer and I am in the process of building a hitmanesque game, just because i love that style of game and I want to increase my skills on something fun, so if you do know what i'm talking about have some examples with involving both models and programming (i use c++ and mainly Ogre3D at the moment but i am getting into unity and XNA) i would greatly appreciate it. Thanks.

  • Model a chain with different elements in Unity 3D

    - by Alex
    I have to model, in unity 3D, a chain that is composed of various elements. some flexible, some rigid. The idea is to realize a human-chain where each person is linked to the other by their hands. I've not tried to implement it yet as i've no idea on what could be a good way to do it. In the game i've to manage a lot of chains of people... maybe also 100 chains composed of 11-15 people. The chain will be pretty simple and there won't be much interaction... Probabily some animation of the people one at time for each chain and some physic reaction (for example pushing a people in a chain should slightle flex the chain) the very problem of this work is that in the chain each object is composed by flexible parts (arms) and rigid parts (the body) and that the connection should remain firm... just like when people handshake... hands are firm and are the wrists to move. i can use C4D to model the meshes. i know this number may cause performance problems, but it's also true i will use low-poly versions of human. (for the real it won't be human, but very simple toonish characters that have harms and legs). So actually i'm trying to find a way to manage this in a way it can work, the performance will be a later problem that i can solve. If there is not a fast 'best-practiced' solution and you have any link/guide/doc that could help me in finding a way to realize this is, it would be very appreciated anyway if you post it. thanks

  • CSOM (Client Side Object Model) - What's new with SharePoint 2013

    - by KunaalKapoor
    SharePoint CSOMThe Client-Side Object Model or CSOM came out with SharePoint 2010. CSOM is accessible through client.svc but all client.svc calls must go through supported WFC entry points (supported entry points are .NET, Silverlight and JavaScript). So a developer would need to use client side proxy objects exposed by either a .NET assembly or a JavaScript library. Changes with SharePoint 2013REST Capabilities - Direct access to client.svcNew APIs - App ModelREST CapabilitiesOne of the most important changes to the CSOM with SharePoint 2013 is that the web service entry point of client.svc has been extended to allow direct access  via REST-Based web service calls. This is a really critical change since its going to make the SharePoint platform accessible to any other platform, opening the horizons of integration and collaboration with other REST based platforms and devices. OData (a really popular standard data access API for HTTP-based clients) is supported similar to 2010 but will be a more important aspect of SharePoint 2013 development.New API'sCSOM for SharePoint 2013 has been buffed up with several new APIs for not only SharePoint server functionality but also an API for Windows Phone applications. For a SharePoint 2010 farm most of the new APIs mentioned below are available only via server side APIs:SearchTaxonomyPublishingWorkflowUser ProfilesE-DiscoveryAnalyticsBusiness DataIRMFeedsSharePoint 2013 remote APIs being accessible through both CSOM and REST is very important to the new app model where developers can no longer run code in a SharePoint environment nor can they access the server-side APIs. So CSOM plays the savior here.Also, you can now substitute the alias '_api' in order to reference '_vti_bin/client.svc'.

  • Light on every model and not in the whole scene

    - by alecnash
    I am using a custom shader and try to pass the effect on my Models like that: foreach (ModelMesh mesh in Model.Meshes) { foreach (ModelMeshPart part in mesh.MeshParts) { part.Effect = effect; } mesh.Draw(); } My only issue is that every Model now has its own light source in it. Why is this happening and is this a problem of my shader? Edit: These are the parameters passed to the shader: private void Get_lambertEffect() { if (_lambertEffect == null) _lambertEffect = Engine.LambertEffect; //Lambert technique (LambertWithShadows, LambertWithShadows2x2PCF, LambertWithShadows3x3PCF) _lambertEffect.CurrentTechnique = _lambertEffect.Techniques["LambertWithShadows3x3PCF"]; _lambertEffect.Parameters["texelSize"].SetValue(Engine.ShadowMap.TexelSize); //ShadowMap parameters _lambertEffect.Parameters["lightViewProjection"].SetValue(Engine.ShadowMap.LightViewProjectionMatrix); _lambertEffect.Parameters["textureScaleBias"].SetValue(Engine.ShadowMap.TextureScaleBiasMatrix); _lambertEffect.Parameters["depthBias"].SetValue(Engine.ShadowMap.DepthBias); _lambertEffect.Parameters["shadowMap"].SetValue(Engine.ShadowMap.ShadowMapTexture); //Camera view and projection parameters _lambertEffect.Parameters["view"].SetValue(Engine._camera.ViewMatrix); _lambertEffect.Parameters["projection"].SetValue(Engine._camera.ProjectionMatrix); _lambertEffect.Parameters["world"].SetValue( Matrix.CreateScale(Size) * world ); //Light and color _lambertEffect.Parameters["lightDir"].SetValue(Engine._sourceLight.Direction); _lambertEffect.Parameters["lightColor"].SetValue(Engine._sourceLight.Color); _lambertEffect.Parameters["materialAmbient"].SetValue(Engine.Material.Ambient); _lambertEffect.Parameters["materialDiffuse"].SetValue(Engine.Material.Diffuse); _lambertEffect.Parameters["colorMap"].SetValue(ColorTexture.Create(Engine.GraphicsDevice, Color.Red)); }

  • Separate collision mesh model?

    - by Menno Gouw
    I want to have another go at 3D within XNA. What I have seen from some other games that they just have a separate very low poly model "cage" around the environment model. However I can not find any reference to this. I have not that much experience with XNA 3D either. Is it possible to have this cage within each of my environmental models already? Lets just say I call the mesh within the .FBX wall and col_wall. How would I call to these different meshes within XNA? The player would just have a tight collision cube around. To make it a bit more efficient I will be making divide the map up by cubes and only calculate collision if the player is in it. Question two: I can't find anywhere to do cube vs mesh collision. Is there a method for this? Or perhaps it is possible to build my collision cage out of cubes in the 3D app and on loading of the models in XNA replace them directly by cubes? So I could just do box to box collision which should be very cheap and still give the player the ability to move over ledges on the static models.

  • Common way to store model transformations

    - by redreggae
    I ask myself what's the best way to store the transformations in a model class. What I came up with is to store the translation and scaling in a Vector3 and the rotation in a Matrix4. On each update (frame) I multiply the 3 matrices (first build a Translation and Scaling Matrix) to get the world matrix. In this way I have no accumulated error. world = translation * scaling * rotation Another way would be to store the rotation in a quaternion but then I would have a high cost to convert to a matrix every time step. If I lerp the model I convert the rotation matrix to quaternion and then back to matrix. For speed optimization I have a dirty flag for each transformation so that I only do a matrix multiplication if necessary. world = translation if (isScaled) { world *= scaling } if (isRotated) { world *= rotation } Is this a common way or is it more common to have only one Matrix4 for all transformations? And is it better to store the rotation only as quaternion? For info: Currently I'm building a CSS3D engine in Javascript but these questions are relevant for every 3D engine.

  • Can't load model using ContentTypeReader

    - by Xaosthetic
    I'm writing a game where I want to use ContentTypeReader. While loading my model like this: terrain = Content.Load<Model>("Text/terrain"); I get following error: Error loading "Text\terrain". Cannot find ContentTypeReader AdventureGame.World.HeightMapInfoReader,AdventureGame,Version=1.0.0.0,Culture=neutral. I've read that this kind of error can be caused by space's in assembly name so i've already removed them all but exception still occurs. This is my content class: [ContentTypeWriter] public class HeightMapInfoWriter : ContentTypeWriter<HeightmapInfo> { protected override void Write(ContentWriter output, HeightmapInfo value) { output.Write(value.getTerrainScale); output.Write(value.getHeight.GetLength(0)); output.Write(value.getHeight.GetLength(1)); foreach (float height in value.getHeight) { output.Write(height); } } public override string GetRuntimeType(TargetPlatform targetPlatform) { return "AdventureGame.World.Heightmap,AdventureGame,Version=1.0.0.0,Culture=neutral"; } public override string GetRuntimeReader(TargetPlatform targetPlatform) { return "AdventureGame.World.HeightMapInfoReader,AdventureGame,Version=1.0.0.0,Culture=neutral"; } } Does anyone meed that kind of error before?

  • Internationalization messages based in views or in model entities

    - by SJuan76
    I have a small webapp in java and I am adding the internationalization support, replacing texts with labels that are defined in dictionary files. While some texts are obviously unique to each view (v.g. the html title), other refer to concepts from the model (v.g. a ticket, the location or status of such ticket, etc.) As usual, some terms will appear many times in different locations (vg, in both the edition page and in the search page and in the listings I have a "ticketLocation" label). My question is: can I organize the labels around the model concepts (so I have a ticket.location label and I use it everywhere such field is labeled) or should I make a different label for each (so form.ticketLocation and filter.ticketLocation and list.ticketLocation). I would go for the first option; I have searched for tips and the only thing that I see that could hinder me is due to the length of the string disrupting the design, and even for that I would prefer having to add a ticket.locationShort for places where there is not much space. What is your opinion/tips/experience?

  • Data model for unlockable card collection

    - by Karlos Zafra
    My game has a collection of cards (about 64) that are unlocked (one by one) provided that 4 items are collected/gained in the game. Right now the deck of cards is modeled with a plist file, like this: <plist> <dict> <key>card1</key> <dict> <key>available</key> <true/> <key>series</key> <integer>1</integer> <key>model</key> <integer>1</integer> <key>color</key> <integer>1</integer> </dict> <key>card2</key> <dict> <key>available</key> <false/> <key>series</key> <integer>1</integer> <key>model</key> <integer>1</integer> <key>color</key> <integer>2</integer> </dict> The value for the key named "available" marks if the item is locked or not. Right now I have to include the data for the items collected by the user, but including that inside the plist looks like too much hassle. What kind of structure should be more suitable for this? How do you manage a collection of unlockable items like this?

  • ViewModel with SelectList binding in ASP.NET MVC2

    - by Junto
    I am trying to implement an Edit ViewModel for my Linq2SQL entity called Product. It has a foreign key linked to a list of brands. Currently I am populating the brand list via ViewData and using DropDownListFor, thus: <div class="editor-field"> <%= Html.DropDownListFor(model => model.BrandId, (SelectList)ViewData["Brands"])%> <%= Html.ValidationMessageFor(model => model.BrandId) %> </div> Now I want to refactor the view to use a strongly typed ViewModel and Html.EditorForModel(): <% using (Html.BeginForm()) {%> <%= Html.ValidationSummary(true) %> <fieldset> <legend>Fields</legend> <%=Html.EditorForModel() %> <p> <input type="submit" value="Save" /> </p> </fieldset> <% } %> In my Edit ViewModel, I have the following: public class EditProductViewModel { [HiddenInput] public int ProductId { get; set; } [Required()] [StringLength(200)] public string Name { get; set; } [Required()] [DataType(DataType.Html)] public string Description { get; set; } public IEnumerable<SelectListItem> Brands { get; set; } public int BrandId { get; set; } public EditProductViewModel(Product product, IEnumerable<SelectListItem> brands) { this.ProductId = product.ProductId; this.Name = product.Name; this.Description = product.Description; this.Brands = brands; this.BrandId = product.BrandId; } } The controller is setup like so: public ActionResult Edit(int id) { BrandRepository br = new BrandRepository(); Product p = _ProductRepository.Get(id); IEnumerable<SelectListItem> brands = br.GetAll().ToList().ToSelectListItems(p.BrandId); EditProductViewModel model = new EditProductViewModel(p, brands); return View("Edit", model); } The ProductId, Name and Description display correctly in the generated view, but the select list does not. The brand list definitely contains data. If I do the following in my view, the SelectList is visible: <% using (Html.BeginForm()) {%> <%= Html.ValidationSummary(true) %> <fieldset> <legend>Fields</legend> <%=Html.EditorForModel() %> <div class="editor-label"> <%= Html.LabelFor(model => model.BrandId) %> </div> <div class="editor-field"> <%= Html.DropDownListFor(model => model.BrandId, Model.Brands)%> <%= Html.ValidationMessageFor(model => model.BrandId) %> </div> <p> <input type="submit" value="Save" /> </p> </fieldset> <% } %> What am I doing wrong? Does EditorForModel() not generically support the SelectList? Am I missing some kind of DataAnnotation? I can't seem to find any examples of SelectList usage in ViewModels that help. I'm truly stumped. This answer seems to be close, but hasn't helped.

  • MVC model flow?

    - by fuzzygoat
    I am setting up an application using the MVC model and I have a query regrading the flow of information from the UI to the data model. What I need to do is place data from the UI in the model, what I have done is write a method in the view which collects the required data in an object and then passes it to the model. The model then takes ownership of the data so that the view can release its ownership. Does this sound sensible?

  • Table Disobeys W3C Box Model, Ie8 Ignores Fixed Table Width !

    - by Axel Myers
    Hi, I'm having hard time with tables and column widths. Update: I'm using XHTML Strict 1.0. The page is: http://www.pro-turk.net/try The first problem I have is, I have a column with a fixed width of 100px and 4px padding, but it disobeys my padding depending on the value. The column width (as the distance between two borders according to W3C Box Model) is 156 px even if padding is 0 or 4. Only the position of the text changes. According to W3C Box Model ( available at www.pro-turk.net/box_model.png ), borders and paddings aren't included in WIDTH attribute, so why does it render wrongly ? The second problem is, when you look the page I gave with IE8, the first cell in the second row has 150px fixed width, but ie shows it about 50% of the total table width regardless of what i say.
