Java Jinput: rescan / reload controllers

不羁的心 提交于 2019-12-06 09:03:41
问题 I am using java jinput library to read data from joypad, and I have trouble reloading Controllers , I use this to load them: public Controller[] findStickControllers() { ControllerEnvironment ce = ControllerEnvironment.getDefaultEnvironment(); Controller[] cs = ce.getControllers(); System.out.println(cs.length); //test ArrayList<Controller> sel = new ArrayList<>(); for (Controller c: cs) { if(c.getType() == Type.STICK) { sel.add(c); } } return sel.toArray(new Controller[]{}); } This works

Rails 5: Displaying form from Joined table

最后都变了- 提交于 2019-12-06 08:57:52
This is my first foray into joined tables and Many-to-Many relationships and I am relatively new to Ruby/Rails as well. This is a direct follow up to a previous question where I built out the appropriate related tables/Models. But for sake of clarify, I'll redefine the layout here... My Models: order.rb class Order < ApplicationRecord belongs_to :user has_many :quantities has_many :meals, through: :quantities end meal.rb class Meal < ApplicationRecord has_many :quantities has_many :orders, through: :quantities end quantity.rb class Quantity < ApplicationRecord belongs_to :order belongs_to

Python: Unable to solve a differential equation using odeint with signum function

二次信任 提交于 2019-12-06 08:51:19
I am trying to solve this problem: where U is here: s=c*e(t)+e_dot(t) and e(t)=theta(t)-thetad(t) and e_dot(t)=theta_dot(t)-thetad_dot(t) where thetad(theta desired)=sin(t)-- i.e signal to be tracked! and thetad_dot=cos(t),J=10,c=0.5,eta=0.5 I tried first with odeint- it gave error after t=0.4 that is theta(solution of above differential equation) fell flat to 0 and stayed thereafter. However when I tried to increase mxstep to 5000000 I could get somewhat correct graph till t=4.3s. I want to get a pure sinusoidal graph. That is I want theta(solution of the above differential equation) to track

Rails: Dividing up a single database between multiple subdomains

天涯浪子 提交于 2019-12-06 07:56:59
问题 I'm relatively new to Rails, and here is my situation: I'm building an inventory management app with rails to help three separate branches of a company manage their own product inventory. Each of these three branches are keeping track of the same products, use the same data models, but are managed separately. My plan is to build a single app using a single database, but one that keeps track of the inventory in all three branches. My plan is to have something like this: branch1.inventoryapp

PHP Slim Framework Create Controller

十年热恋 提交于 2019-12-06 07:28:07
问题 I am creating an API using the Slim framework. Currently I use a single file to create the route and pass a closure to it: $app->get('/', function($req, $resp){ //Code... }) But I realise that my file has grown rapidly. What I want to do is use controllers instead, so I will have a controller class and just pass the instance/static methods to the route, like below class HomeController { public static function index($req, $resp){} } and then pass the function to the route $app->get('/',

rails - redirect back unless previous page was artist page

丶灬走出姿态 提交于 2019-12-06 07:11:48
I'd like to redirect back to the previous page, UNLESS the previous page was my 'artist' controller's 'show' action. So I guess it would look something like: if *previous page was artist show* redirect_to [track.artist, track] else redirect_to :back end My question is - how do I test if the previous page was my artist controller's show action..? Perhaps request.referer is what you're looking for? Then you can say something like: if request.referer == artist_url(track.artist) redirect_to [track.artist, track] else redirect_to :back end 来源: https://stackoverflow.com/questions/4877093/rails

Categories of controllers in MVC Routing? (Duplicate Controller names in separate Namespaces)

自闭症网瘾萝莉.ら 提交于 2019-12-06 06:50:19
问题 I'm looking for some examples or samples of routing for the following sort of scenario: The general example of doing things is: {controller}/{action}/{id} So in the scenario of doing a product search for a store you'd have: public class ProductsController: Controller { public ActionResult Search(string id) // id being the search string { ... } } Say you had a few stores to do this and you wanted that consistently, is there any way to then have: {category}/{controller}/{action}/{id} So that

asp.net mvc controller post best practices

喜夏-厌秋 提交于 2019-12-06 06:38:10
I am bit confused about "best practice" controller using question. My typically code look public ActionResult Edit(int reportId,FormCollection formCollection) { try { var report = _dbContext.EmployeeReports.Find(reportId); if (TryUpdateModel(report)) { _employeeReportService.Update(report); return RedirectToAction("List"); } return View("Edit", report); } catch (Exception) { // some logging etc return RedirectToAction("List"); } Well, is better using "TryUpdateModel" or only "UpdateModel" or simple call Model.IsValid and is good idea to catch exception in controller? Thanks This depends if you

Symfony 2 sharing data between controllers

强颜欢笑 提交于 2019-12-06 06:15:15
I have started to create a project using Symfony 2. I need to share data between all controllers. I have added a base controller which extends symfony\controller and each of my controllers extends this base controller class BaseController extends Controller class HomeController extends BaseController This base controller will be used for things like assigning global twig variables ( I know I can do this in the config but some of the variables will be gotten from other config files and database ). So I thought I could reference container since Controller is container aware, however it isn't at
