Updating object properties in twig

Question

Is there a way to update an object\'s property in twig?

An object like the following is passed to twig:

object
   property1
   property2

Answer 1

If your property is array (object->property['key']) you can do something like this:

{% set arr = object.property|merge({"key":['some value']}) %}
{{ set(object, 'property', arr) }}

That equivalent to:

this->property['key'][] = 'some value';
