问题
I want to pass my ng-model from the 'outer-directive' to an 'inner-diretive' (which is contained in the outer-directive template).
What is the correct way for doing it?
HTML code:
<body>
<outer-directive ng-model="prop" />
</body>
and directive code:
angular.module('app', []).directive('outerDirective', function(){
return {
template: '<inner-directive ng-model="prop" />',
link: function() { ... }
}
});

You can set up a bi-directional binding (see the documentation, section "Directive Definition Object") with the variable in ngModel attribute, as with any other directives:
<my-directive ng-model="foo"></my-directive>
myApp.directive('myDirective', function () {
return {
template: '<div><input type="text" ng-model="ngModel" /></div>',
replace: true,
scope: {
ngModel : '=',
},
};
});
Fiddle

i think you need to pass the form in the directive and set the form dirty manually
<directive directive-form="editForm" ></directive>
scope: {
directiveForm:"="
},
link: function (scope, $elem, $attrs)
{
scope.directiveForm.$setDirty();
}
