Controller 'ngModel', required by directive '…', can't be found

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 in use:

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

Here is the actual error text:

Error: [$compile:ctreq] Controller 'ngModel', required by directive 'submitRequired', can't be found!

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

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

One possible solution to this issue is ng-model attribute is required to use that directive.

Hence adding in the 'ng-model' attribute can resolve the issue.

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

You can also remove the line

  require: 'ngModel',

if you don't need ngModel in this directive. Removing ngModel will allow you to make a directive without thatngModel error.

I faced the same error, in my case I miss-spelled ng-model directive something like "ng-moel"

Wrong one: ng-moel="user.name" Right one: ng-model="user.name"
