controller

问题 i have the following base controller... public class BaseController : Controller { protected override void Initialize(System.Web.Routing.RequestContext requestContext) { if (something == true) RedirectToAction("DoSomething", "Section"); base.Initialize(requestContext); } } Basically, all my controllers will derive from BaseController, and it will redirect them if a certain value is true. However, this code does not work!!! The call to RedirectToAction is made, but after the Initialize method

问题 While reading cocoa tutorials i've noticed that some of the tutorials use AppDelegate and some AppController for defining IBActions that open various windows that use subclasses of NSWindowController . Is there some sort of rule of thumb for this? 回答1: It's just a class name. AppDelegate implies that the class's main duty is as NSApplication's delegate, whereas AppController seems to imply a broader range of responsibility. 回答2: I create one class that is solely my app delegate, and

问题 Is there any way in Spring 3 MVC to gain access to the request header information (like source IP address etc.), when parsing a request in a @Controller? 回答1: You can retrieve it from HttpServletRequest , using getRemoteAddr() to get access to user IP address and getHeader() to get header value. For example @Controller public class MyController { @RequestMapping(value="/do-something") public void doSomething(HttpServletRequest request) { final String userIpAddress = request.getRemoteAddr();

问题 I'm new to .Net development, and now are following NerdDinner tutorial. Just wondering if any of you would be able to tell me What is the differences between ViewData and ViewModel (all I know is they are used to pass some form of data from controller to view) and perhaps tell me on what situation should I use ViewData instead of ViewModel and vice versa Thanks in advance! Sally 回答1: ViewData: In short, use ViewData as support data, such as a datasource to a SelectList. ViewModel: ASP.NET MVC

问题 I have seen a few exmaples on stack overflow about this ng-init issue, although I cant seem to find one which references it with the use of a controller. I have called the function in the controller by having the following in the html file <div class="tab-container" ng-controller = "ExampleController" ng-init = "init()" > In the controller: $scope.init = function(){ alert("do something"); }; It does run, but it runs before the components have loaded on the screen. Am i missing something?

问题 I'm loving JavaFX and SceneBuilder, but I just can't figure out how to make SceneBuilder link my FXML views with their Java controllers when they are not in the same folder. I'd just like to have this folder structure: package |-- model |-- view | |--someElementView.fxml | \--anotherElementView.fxml \-- control |--someElementController.java \--anotherElementController.java Instead I can only make SceneBuilder recognise my controllers if I have this folder structure which I'd like to avoid:
