I have a controller with an attribute directive inside it, that directive needs the ngModel of it's controller parent.
See this Plunkr .
Problem
Although the form loads correctly, the log inside the directive displays this:
a.$…t.aa {$attr: Object, $$element: R[1], fieldValidator: "", boundModel: "person", ngModel: undefined}
Any idea why ngModel is undefined and why boundModel contains the string 'person'? I've been staring too long at this ...
try this
app.directive('fieldValidator', [function(){
return {
restrict: 'A',
scope: {
boundModel: '='
},
controller: function($scope){
},
link: function ($scope, $elem, $attrs) {
console.log($scope.boundModel);
}
}
}]);
like other said, there was no ng-model where you use this directive. boundModel: '='
is short for boundModel: '=boundModel'
And if you want to access boundModel then just use $scope.boundModel ignore what show in $attr guess that not what you need.
{ boundModel: '=ngModel' }
means that you pass boundModel
property through ng-model
attribute. But in a template you don't use ng-model
attribute. You have bound-model
instead.
scope: {
boundModel: '=ngModel'
},
You incorrectly use the scope variables. When you say '=ngModel', you say that there is an attribute on the directive with the name 'ng-model', which you want to use inside your directive as scope.boundModel.
It seems that you want to use ng-model controller, why do you not just use ng-model on your directive instead of boundModel?
You could rename the bound-model in you html to ng-model, and remove the scope from the directive. If you want to use the ngModelController you will need to inject this in the directive link function like this:
return {
restrict: 'A',
required: '^ngModel',
scope: {},
controller: function($scope){
},
link: function ($scope, $elem, $attrs, ngModel) {
console.log($attrs);
}
}
With the ngModelController you can then set validity etc. of the person you bind to the ng-model in the html as documented here .
