How can I support ngMessage in a directive if the form element is not an input?

Question

Angular

I have a form element. This is such a file loader. It's a whole little component. But as a directive.

<div s3 options="options" ng-model="form.files"></div>

Everything works, and I require ngModel in the directive. I can appoint
ngModel.$setValidity('upload', false);
But that's just no use. How will I catch it in ngMessage? because there is something like
<div ng-messages="testForm.upload.$error">
Where upload is the name of the element. But it must be either an input or a select. And I have neither. So I appointed this validation, but how can I catch it now?

Answer 1

ngMessages stupidly takes the expression that you feed it.
form registers controls and takes their name from the $name property, which by default is taken from the name attribute .
Conclusion, you can:
- add the name or data-name attribute
- set the name of the control yourself using ngModelController
