How to “count” user inputs from a Controller

由 旧城冷巷雨未停 提交于 2019-12-13 02:38:28
问题 I have a @shows Controller where every user can create a Show ( Singular ). On the Show Creation View ( shows/new ) i want to display a counter of how many shows there are already. i tried: def count @shows.all.count end # in my Shows Controller and then called <%= @count %> on my view. But i guess this isn't the right way. I tried calling it directly on my View: <%= @shows.count %> but neither this worked. Can someone help me out ? 回答1: @show_count = Show.count will do your job. In your view

Changes not reflected across view when using binding in cocoa

由 ぐ巨炮叔叔 提交于 2019-12-13 02:23:27
问题 I am creating some sample applications to understand the concepts of view navigation, binding etc in cocoa. Here is the scenario: I have a window that has a tab view(2 tabs) in MainMenu.Xib. I have a text field in the first tab and label in the second tab. I want both of them to reflect the same value and I want to do this using binding. Also, I don't want to use the views provided to me along with the tab view. These are the steps I have done. The view of each tab view item is set separately

Which is the preferred way of defining an AngularJS controller?

由 北慕城南 提交于 2019-12-13 02:16:18
问题 As an example, we have this index.html code: <!DOCTYPE html> <html ng-app="sample"> <head> ... </head> <body> <div ng-controller="myController"> ... <script src="js/modules/app.js"></script> </div> </body> </html> and in app.js we have a module and a controller: var app = angular.module('sample', []); // controller here So my question is that, I have seen controllers defined in two types, as a controller, and as a plain function: app.controller('myController', function(args){ ... }); or var

问题 In my Find controller I have a method like: public Result findLatest(String repoStr) { ............ } Which is linked through a route: GET /latest controllers.Find.findLatest(repo: String) Then, I have a form in a view like: <form action="@routes.Find.findLatest()" method="get"> .... <select name="repo">....</select> </form> But obviously that is failing, because it is expecting some parameters that I do not fulfill in the action. What is the correct way to do this without having to end up

Spring @Controller lifecycle

由 会有一股神秘感。 提交于 2019-12-13 02:02:48
问题 I am new to Spring MVC and would like to know how it handles requests, more specifically: I would like to know how a Spring @Controller's life cycle relates to that of a Servlet? I would also like to better understand what are the best practices for multi-threaded enviornments (e.g. like in Servlets, are class attributes visible to multiple HTTP requests as objects are reused from the pool)? 回答1: A controller (as any spring bean) has a scope. At best your controllers should be of scope

PHP export array to json for an angular app

问题 I exported data from MySql db to Json object. What I want to achieve is actually to see the front end data manipulations by angular. I think that the problem is in my controller. I placed the Json object inline in ng-init and it works great. I tried to lean on this question but with not much success This is my HTML file <html ng-app="myApp"> <head> <title></title> </head> <body> <div style="direction: ltr"> </div> <h1>תוצאות שאלון</h1> <div class="table-responsive" ng-controller="ContentCtrl"
