问题 I am going to develop a winform project of considerable size. I am planning to use Entity Framework as ORM tool. Now I am searching for an architecture(MVC/MVP/MVVM etc..) to implement all these. Firstly there are few choices for n-layered architecture for windows forms and most those I get are written prior to EF came into market. I got a framework called Rocket Framework from codeplex(http://rocketframework.codeplex.com) I have looked around it but am skeptical that it will accommodate a

问题 I'm going to start a project using a Zend Framework MVC implementation. How do I work with ajax? I mean, should I place all ajax code into controller? Or into view? For example, I want to get posts from author 'ivan' to show on a page. Normally, I create a link to '/posts/author/ivan' or smth like it, create a new Action like 'byAuthorAction()' in the Posts controller (or maybe Users controller, wherever), view for it (and all code what gets posts from model goes there) and create a new Route

问题 I have rails app with the following structure: user has_many posts post has_many post_comments post_comment has_many comment_replies I'm planning to use the following routes to avoid deep nesting. resources :posts do resources :post_comments, module: :posts end resources :comments do resources :comment_replies, module: :post_comments #is this module a good choice? end This gives the following controller structure post_comments GET /posts/:post_id/comments(.:format) posts/comments#index POST

问题 Reloading the page or manually type URL like "localhost/mysite.com/contact" gives wrong "Not Found"(404 error) on the server. This is because MVC does not know about angular routing and by MVC pattern it will look for an MVC page for 'contact' which does not exist in MVC routing path. I think there is a solution by .haccess file by redirect all links to the index page, but it, not a good idea. I already add a baseURL constant to the application in head. and the js part is below: app.config

问题 I have a following POCO class. I don not want the parameterless constructor to be public. public class FileDownloadRequest { //public FileDownloadRequest() { } public FileDownloadRequest(int fileId, RepositoryFolderTypes fileType) //RepositoryFolderTypes is an enum, not a class { this.FileId = fileId; this.FileType = fileType; } public int FileId { get; set; } public RepositoryFolderTypes FileType { get; set; } //an enum } When I am trying a https://10.27.8.6/Files/DownloadFile?fileId=1

问题 I'm using the Play Framework for a web app in Java. I'd like to put an Account controller in an "account" subpackage, for example: |- controllers |- account |- Account.java While my views are organized like: |- views |- Account |- index.html The Account.java file contains: package controllers.account; import play.mvc.Controller; public class Account extends Controller { public static void index() { render(); } } I'd like to have the following behavior: when a request is made to http:/

问题 I've got a model that does some validation checking and adds the errors to ModelState: ViewData.ModelState.AddModelError("mycontrol", "message") They display fine on the view side, but is there a way to set the focus to the control that corresponds to the validation message? Right now, the page refreshes and stays at the top of the page, so if the error is towards the end of the page, it's not obvious to the user what happened. Note: Another solution would be for ValidationSummary to show the
