问题 If you create CRUD-code for an entity in Symfony2 using the console, you will end up with a very basic delete function. This function is lean and efficient, but does not provide an "are you sure?"-confirmation. If the entity to be deleted exists, it will be deleted immediately. Does anyone have suggestions for the easiest way to add user confirmation? Up until now I have been using: An extra controller function jQuery It seems a bit weird though that Symfony2 would have no built-in option for

问题 I'm rendering a js.erb partial which enables ajax functionality to like/dislike a restaurant dish. I recently came across the around_action callback and figured yield would help perform the controller action first and render the template second. Unfortunately I'm getting a 500 (Internal Server Error) due to the respond_to never getting called. The respond_to method works if I place it inside the controller action but not inside the callback. What am I doing wrong? class DishesController <

问题 I need to use a function in multiple controllers. So I though about using a custom helper, but it seems I can't get it to work. (It works in the view, but I need it in the controller) It gives me following Fatal Error: Fatal error: Call to undefined method Developers::checkIfLoggedIn() in /application/controllers/developers.php on line 12 Is it a smart move to use a helper to use a function in multiple controllers, or should I do it otherwise. Thanks in Advance, Mark EDIT: Controller file: if

问题 I have some CodeIgniter controllers which should only be accessed by users who have logged in (i.e. where $this->session->userdata('username') is not null). If a non-authenticated person attempts to access said controllers they should receive: header('location: /auth/login'); There has got to be a better way to do this than to put a if (!$this->session->userdata('username')) header('location: /auth/login'); else { [rest of function] } in front of every function in the controller... I know DX

问题 I have a website built using ASP.NET MVC3 which is layered as follows: ProjectName.Shared (model + service contracts) ProjectName.Infrastructure ProjectName.Data ProjectName.Data.Sql ProjectName.Managers (Business layer) ProjectName.Services (WCF services) ProjectName.UI.Main (ASP.NET MVC3 application) This is actually the structure I recently came up with after some refactoring.

问题 Have a question about the design/usage of asp.net mvc here. In the html helper class, you can get to the current controller by Html.ViewContext.Controller. Moreover, you can get to the request, route collection and much more from the html helper class. Doesn't this go against the rule of MVC? Doesn't this opens up a ways for developer to do heavy controller dependent code in views? If not, what's the best practice use case for current viewcontext and controller from the html helper class?

问题 I'd greatly appreciate some help regarding a Laravel 4 issue I'm experiencing. I'm testing controller routes, specifically a controller that is responsible for routing responses for a questionnaire. I'm testing scenarios such as: the user attempting to skip a question, the user requesting a question that doesn't exist... etc. The tests that I've written for all scenarios up until now work as expected using PHPunit. The test I'm currently writing involves several $this->call() or $this->client
