阅读更多关于 Laravel 5: The difference between Auth::guard($this->getGuard())->login($user); and auth()->login($user);

问题 What is the difference between: Auth::guard($this->getGuard())->login($user); and auth()->login($user); ? For example, in PasswordController.php we can have: protected function resetPassword($user, $password) { $user->password = $password; $user->save(); Auth::guard($this->getGuard())->login($user); } or protected function resetPassword($user, $password) { $user->password = $password; $user->save(); auth()->login($user); } (in this case, we create a mutator in Users.php to bcrypt password AND

Java Swing GUI design techniques for user actions validations (MVC-FSM)

阅读更多关于 Java Swing GUI design techniques for user actions validations (MVC-FSM)

问题 I have implemented GUIs using Swing and always tried to follow the MVC pattern as much as I could. I was wondering though, if MVC is not the only part of the puzzle. Are FSMs used in GUI's design as well? I have never used an FSM in a GUI and my approach was: on action, the corresponding method of the controller was called, to endup updating the model, finishing with updating the view. Usually upon a request triggered by a user's action I used some simple checks to make sure that the user

Let me start by explaining that in Backbone, your Views are a mix of traditional Views and Controllers, and your HTML Templates are the traditional MVC Views Been racking my head about this for a while and I'm not sure what the right/pragmatic approach should be.

Hard-coded @RequestMapping URL in Spring MVC Controller

阅读更多关于 Hard-coded @RequestMapping URL in Spring MVC Controller

问题 I'm studying Spring 3 and I'm using it in a simple web-application. Now I'm implementing a Spring MVC Controller using annotations, and I'm wondering: Is there any best practice using @RequestMapping annotation? I mean: I've seen that usually the URL mapped in this annotation is hardcoded in the class... Is there a way to pass the URL in a 'loosely coupled way' (to obtain a more reusable class)? I know that there are some wild cards that can be used, but I think that isn't the solution... Am

PHP MVC - How can Controller and View access same instance of Model?

阅读更多关于 PHP MVC - How can Controller and View access same instance of Model?

问题 I'm developing my own PHP MVC for a database application, which I'd already completed but using monolithic classes that do everything - MySQL processing, input processing and display. It works great but it's a nightmare to debug and to make alterations! I've recently discovered MVC's and in the process of rewriting the app - it's all on the drawing board at the moment so I haven't actually got any code to share with you. There's one thing I'm stumbling on: I've got it that the Controller
