controller

问题 I want to store items in the application cache so it's lazy loaded from the main layout view. I also want to be able to invalidate the cache, so if it's invalid, next time when the items-collection is requested, it's reloaded to that cache location. Here's what I've implemented: In the controller: protected IEnumerable<Slide> CachedSlides { get { return HttpContext.Application[SlidesCacheKey] as IEnumerable<Slide>; } set { HttpContext.Application[SlidesCacheKey] = value; } } private void

问题 I was updating my Laravel 3 app to Laravel 4 when I hit this problem... Routes I have tried: Route::get('backend/login', 'backend/UserController@login'); Route::get('backend/login', 'backend.UserController@login'); 回答1: I had a similar issue just a few hours ago and had to play a little bit with it to have it working.

问题 This is my controller: def addcar @car = Car.new(params[:car]) render :action => "list" end this is my view: <%(@allcars).each do |cell|%> <p><%= link_to cell.to_s, :controller => "car", :action => "addcar", :car => cell.to_s %></p> <%end %> In the link_to statement I want to pass cell.to_s to the controller.

问题 I'm currently working on a project with Codeigniter. I have one controller called Cat class Cat extends CI_Controller { function __construct(){ parent::__construct(); } function index($action){ // code here } } and a route (in routes.php) $route['cats/:any'] = 'cat/index/$1'; And that works if I use this URL for example: http://www.mywebsite.com/cats/display Nevertheless, if the user changes the URL to http://www.mywebsite.com/cats/ it doesn't work anymore. Codeigniter writes: 404 Page Not

问题 Very frustrating for the last few days. I have a rails app with Devise installed where I generated a new User model and I generated Devise views as well. This happens when I try to sign in as an existing user right when I click "Log in" after filling out the email and password fields: AbstractController::ActionNotFound - Could not find devise mapping for path "/sessions/user". This may happen for two reasons: 1) You forgot to wrap your route inside the scope block. For example: devise_scope

问题 Scenario I am creating a GUI where multiple views reference the same model object. What I am Accustom to In Swing, if i want all the views to reference the same model i would pass the model into the constructor. What I am Currently Doing In JavaFX, I am passing the model around by having a setter method in the views/controllers (menubars, split panes, tabs, ...), after each view/controller has been loaded.
