Instance Method Details

#translate(key, options = {}) ⇒ Object Also known as: t

Note changing offset from 2 to 1 causes errors in validates_timeliness gem in #format_error_value where it tries to lookup I18n.t(:date) It is actually trying to find the key :date in the scope “validates_timeliness.error_value_formats” but this does not exist so, becuase of the cascade, it settles on returning the root :date key which is actually a hash, and fails. Using offset: 2 prevents us from ever picking up the root :date key when using t(:date) or t(“.date_”). It does mean we cannot put any translations under eg :en-GB directly, they must be under a sub key eg :thead, :btn etc. offset: 2 means we will be looking back up the tree for e.g. “list.type” if the key is :type and the partial is called ‘list’, so we would never find eg the translation renalware.type; offset: 1 and using skip_root: false seems to do the trick. See the loop in lib/i18n/backend/cascade.rb in the i18n gem. Another issue here is that if offset is 1 then any input called eg f.input :date could resolve to the root :date tranlsation which is a hash of options and not a real translation, leading to errors. Its not possible rename/reloacte these keys as they are hard-coded eg in actionview/lib/action_view/helpers/date_helper.rb
