I've been playing a lot with MVC lately in the forms of ASP.NET MVC and Django (MTV actually) and I must say that I love it. Are there

问题 I have a piece of code that is needed in 2 of my controllers, but not all of them. Where does this method belong? I have read about helpers, but those seem to be for view-related code. Someone proposed the lib-folder, but that seems 'too far away' from the controller logic, i don't need it in views or models. Has someone experience with that sort of problem? 回答1: There are three options, the easiest (though, the most unclean) is the application controller. The other two options are a shared

问题 In many leading DDD projects, especially MVC style, I see the UI using display objects that mirror domain entities, rather than using those domain objects directly. This style is obviously for decoupling and separation of concerns, and I personally prefer this style. But what I'm not sure of, is whether this a strict tenet of DDD, or whether this is more just different developers' interpretation of it. Can you use your domain objects directly in the UI, and still be following the DDD

问题 I'm trying to use resources mapping feature of Spring 3 and it does not seem to be working. Here is what I have: <servlet> <servlet-name>aaa</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>aaa</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping> in my web.xml then in my aaa-servlet.xml I have the following: <resources mapping="/resources/**" location="

问题 From my understanding, helpers are mainly used to clean up views from some view-specific logic. But on my currently new project (legacy application), I've stumbled upon a lot of helpers that look like this def itemprepare render :partial => 'items/itemlist_summary' end Is this correct? Rendering a partial to me seems like something you would want to do in the view, as it doesn't include any logic that needs to be abstracted. Should I just inline all of these helpers? 回答1: Rendering a partial

问题 Being new to Backbone.js, just wanted to clarify the correct way to go about this simple task. Developing a web app, almost always, you'll have user accounts, where users can login to your app, and view their personalized data. Generally, their page might show some widgets, their user information (name, avatar, etc). Now creating a Model per widget and grouping these in a Collection is an easy concept. However, would their user info be stored in a singular Model, which would not be apart of a

问题 I'm creating a web application with desktop and mobile versions using ExtJS and Sencha Touch. ExtJS 4 and Sencha Touch 2 use an MVC approach, and Sencha Touch 2 incorporates "profiles" for different devices (iPhone, tablet, etc.). ExtJs 4, however, has no notion of profiles. Is it realistically feasible to for dependencies for desktop, iPhone, and iPad versions of the app to live under one vhost, in the same app directory hierarchy? Or, is it generally more acceptable to use different vhosts
