In Rails i18n, how to get all values for a certain key using the following:

I need to be able to get a certain section for example only return everything under "home"

The return value of I18n.backend.send(:translations) is just a hash, so you can access a subset just by passing in the appropriate keys.

e.g. if you have:

en:
  foo:
    bar:
      some_term: "a translation"
      some_other_term: "another translation"   

Then you can get the the subset of the hash under bar with:

I18n.backend.send(:translations)[:en][:foo][:bar]
#=> { :some_term=>"a translation", :some_other_term => "another translation"}
