How to set raise_on_missing_translations for I18n

Question

In rails 6.1.6.1 I have the following deprecation warning

DEPRECATION WARNING: action_view.raise_on_missing_translations is deprecated and will be removed in Rails 7.0. Set i18n.raise_on_missing_translations instead. Note that this new setting also affects how missing translations are handled in controllers.

How do I set the raise_on_missing_translations option, and where do I set it (e.g. in an initializer)?

Answer 1

Set config like this in application.rb or in specific environments:

config.i18n.raise_on_missing_translations = true
