Simple check if form field has errors in Twig template

Question

In Twig template I check if a field has an error like this:

{% if form.points.get(\'errors\') is not empty %}

Is there any method like:

Answer 1

I had a similar problem, but form.points doesn't exist in my twig templates.

I had to get the number of errors in the controller, then pass it into my templates as a variable. $form->getErrors() does not behave as you might expect in your controller though. See this SO question for a function that will get the form errors correctly.
