I'm not sure exactly what you the problem is with the code= method you
have, and how it related to Locale.all.
If you want something similar to the initialize method:
def Locale.call(h)
locale = super
locale.instance_variable_set(:@i18n, I18n.storage.find { |obj|
obj.iso_code == locale.code })
end
or use the after_initialize plugin:
class Locale
plugin :after_initialize
def after_initialize
super
@i18n = I18n.storage.find { |obj| obj.iso_code == code }
end
end
If that still doesn't get you what you want, I'm probably not understanding
the problem correctly, so please put together a minimal self-contained
reproducible example showing the problem in that case.
Thanks,
Jeremy
