# I18n translation metadata is useful when you want to access information
|
|
# about how a translation was looked up, pluralized or interpolated in
|
|
# your application.
|
|
#
|
|
# msg = I18n.t(:message, :default => 'Hi!', :scope => :foo)
|
|
# msg.translation_metadata
|
|
# # => { :key => :message, :scope => :foo, :default => 'Hi!' }
|
|
#
|
|
# If a :count option was passed to #translate it will be set to the metadata.
|
|
# Likewise, if any interpolation variables were passed they will also be set.
|
|
#
|
|
# To enable translation metadata you can simply include the Metadata module
|
|
# into the Simple backend class - or whatever other backend you are using:
|
|
#
|
|
# I18n::Backend::Simple.include(I18n::Backend::Metadata)
|
|
#
