使用变量设置Twig对象属性名称

Question

I need to set an object property name dynamically in Twig:

{% set featureId = feature.id %}
{% set gridEnabled = gridEnabled|merge({featureId: true}) %}

But that sets "featureId" as a property of gridEnabled . Is there a way to tell Twig that featureId is a variable? I'm surprised it interprets that as a string without quotes.

Follow-up question: Here is the full set--I was able to further reduce to "feature.id". Can these lines be combined?

{% set gridEnabled = grid.enabled %}
{% set gridEnabled = gridEnabled|merge({(feature.id): true}) %}
{% set grid = grid|merge({'enabled':gridEnabled}) %}

Answer 1

Very easy actually,

{% set gridEnabled = gridEnabled|merge({(featureId): true}) %}

---

(edit) follow-up

{% set grid = grid | merge({'enabled' : (grid.enabled | merge({(featureId):1,}))}) %}
