I18n "format" for errors won't change

Question

Here is my en.yml config (Rails 7)

en:
  hello: "Hello world"
  activerecord:
    models:
      user:
        one: "User"
        other: "Users"
    attributes:
      user:
        first_name: "First Name"
        last_name: "Last Name"
        email: "Email"
        role: "Role"
    errors:
      format: "%{message} for %{attribute}"
      messages:
        blank: "can't be blank"
        too_short: "is too short (minimum is %{count} characters)"

I try to change the format for errors. I step in console and do I18n.t('errors.format') -> "%{attribute} %{message}" Other change properly, but format dont.

format change from "%{attribute} %{message}" to "%{message} for %{attribute}"

You're checking for I18n.t('errors.format'), but you have it scoped under activerecord. Move it outside of activerecord scope:

en:
  errors:
    format: "%{message} for %{attribute}"
  activerecord:
