Suppose we have a SharePoint list and it has four fields viz. Title, Full Name, Email, Mobile Number etc. Now if you want to apply custom validation in New/Edit Item form, you can easily do it with CSR code. The below mentioned can validate following conditions in forms: Blank values in fields ...

Tracking your app in git Before you can push an app to Heroku, you’ll need to initialize a local Git repository and commit your files to it. For example, if you have an app in a directory, myapp, then create a new repository for it: $ cd myapp $ git init Initialized empty Git repository in .git/...

app\Exceptions\Handler.php public function render($request, Exception $exception) { if ($exception instanceof ModelNotFoundException) { abort(404); } return parent::render($request, $exception); } You can catch / handle any exception that is thrown in Laravel.

One example of machine learning algorithms is the Random Forest alogrithm (Breiman, L. (2001). Random Forests. Machine Learning 45(5), p. 5-32). This algorithm is implemented in R according to Breiman's original Fortran implementation in the randomForest package. Random Forest classifier objects ca...

Heroku aggregates three categories of logs for your app: App logs - Output from your application. This will include logs generated from within your application, application server and libraries. (Filter: --source app) System logs - Messages about actions taken by the Heroku platform infras...

Each log line is formatted as follows: timestamp source[dyno]: message Timestamp - The date and time recorded at the time the log line was produced by the dyno or component. The timestamp is in the format specified by RFC5424, and includes microsecond precision. Source - All of your app...

If you only want to fetch logs with a certain source, a certain dyno, or both, you can use the --source (or -s) and --dyno (or -d) filtering arguments: $ heroku logs --dyno router 2012-02-07T09:43:06.123456+00:00 heroku[router]: at=info method=GET path="/stylesheets/dev-center/library.css&quo...

Lets say continue with User example (you may have controller with store method and update method). To use FormRequests you use type-hinting the specific request. ... public function store(App\Http\Requests\StoreRequest $request, App\User $user) { //by type-hinting the request class, Larave...

Lets have a look at the native app lifecycle methods for different platforms. Android. //Xamarin.Forms.Platform.Android.FormsApplicationActivity lifecycle methods: protected override void OnCreate(Bundle savedInstanceState); protected override void OnDestroy(); protected override void OnPause()...

If the engine is able to correctly predict you're using a specific small type for your values, it will be able to optimize the executed code. In this example, we'll use this trivial function summing the elements of an array and outputting the time it took: // summing properties var sum = (functio...

If you have a ActiveRecord User class with name and email attributes, you could create a factory for it by making the FactoryGirl guess it: FactoryGirl.define do factory :user do # it will guess the User class name "John" email "[email protected]" end end ...

Here is a simple proof by induction. Require Import Coq.Setoids.Setoid. Require Import Coq.Arith.Lt. (* A number is less than or equal to itself *) Theorem aLTEa : forall a, a <= a. auto with arith. (* This follows by simple arithmetic *) Qed. Theorem simplALTE : forall a ...

Consider the following code: public async Task MethodA() { await MethodB(); // Do other work } public async Task MethodB() { await MethodC(); // Do other work } public async Task MethodC() { // Or await some other async work await Task.Delay(100); } ...

It parses the data from the %%GLOBAL_ConversionCode%% template variable, and as such this script should be inserted in order.html immediately after the %%GLOBAL_ConversionCode%% variable. This was originally intended for the Blueprint theme framework and, as such, may not work on Stencil. <scrip...

This was added to assets/js/theme/category.js in loaded(). You will also need to add {{inject "categoryProducts" category.products}} to templates/pages/category.html var mainImages = []; var rollOvers = []; this.context.categoryProducts.forEach(function(e, i) { if (e.images[0])...

The following example shows how to apply custom fonts to a Navigation Bar and includes fixes for some quirky behaviors found in Xcode. One also may apply the custom fonts to any other UIControls such as UILabels, UIButtons, and more by using the attributes inspector after the custom font is added to...

In Coq, destruct more or less corresponds to a case analysis. It is similar to induction except that there's no induction hypothesis. Here is a (admittedly rather trivial) example of this tactic: Require Import Coq.Arith.Lt. Theorem atLeastZero : forall a, 0 <= a. Proof. intros. destr...

By default, floating point operations on float and double do not strictly adhere to the rules of the IEEE 754 specification. An expression is allowed to use implementation-specific extensions to the range of these values; essentially allowing them to be more accurate than required. strictfp disable...
