The controller 'ngModel' required by the '...' directive cannot be found

Question

What's going on here?

Here is my directive:

app.directive('submitRequired', function (objSvc) { return { require: 'ngModel', link: function (scope, elm, attrs, ctrl) { // do something } }; }); 

Here is an example of the directive used:

 <input submit-required="true"></input> 

Here is the text of the actual error:

 Error: [$compile:ctreq] Controller 'ngModel', required by directive 'submitRequired', can't be found! http://errors.angularjs.org/1.2.2/$compile/ctreq?p0=ngModel&p1=submitRequired at http://www.domain.ca/Scripts/angular/angular.js:78:12 at getControllers (http://www.domain.ca/Scripts/angular/angular.js:5972:19) at nodeLinkFn (http://www.domain.ca/Scripts/angular/angular.js:6139:35) at compositeLinkFn (http://www.domain.ca/Scripts/angular/angular.js:5550:15) at nodeLinkFn (http://www.domain.ca/Scripts/angular/angular.js:6132:24) at compositeLinkFn (http://www.domain.ca/Scripts/angular/angular.js:5550:15) at publicLinkFn (http://www.domain.ca/Scripts/angular/angular.js:5458:30) at http://www.domain.ca/Scripts/angular/angular.js:1299:27 at Scope.$get.Scope.$eval (http://www.domain.ca/Scripts/angular/angular.js:11634:28) at Scope.$get.Scope.$apply (http://www.domain.ca/Scripts/angular/angular.js:11734:23) <input submit-required="true"> angular.js:9159 (anonymous function) angular.js:9159 $get angular.js:6751 nodeLinkFn angular.js:6141 compositeLinkFn angular.js:5550 nodeLinkFn angular.js:6132 compositeLinkFn angular.js:5550 publicLinkFn angular.js:5458 (anonymous function) angular.js:1299 $get.Scope.$eval angular.js:11634 $get.Scope.$apply angular.js:11734 (anonymous function) angular.js:1297 invoke angular.js:3633 doBootstrap angular.js:1295 bootstrap angular.js:1309 angularInit angular.js:1258 (anonymous function) angular.js:20210 trigger angular.js:2315 (anonymous function) angular.js:2579 forEach angular.js:300 eventHandler angular.js:2578ar.js:7874 

Answer 1

As described here: Angular NgModelController , you must provide the <input required ngModel controller

 <input submit-required="true" ng-model="user.Name"></input> 

Answer 2

One possible solution to this problem is the ng-model attribute to use this directive.

Therefore, adding to the attribute 'ng-model' may solve the problem.

 <input submit-required="true" ng-model="user.Name"></input>
