Instance Method Details

#t(key, options = {}) ⇒ Object

Extended translate function

Parameters

key<Symbol,String>

the key (same as parameter to translate function)

options<Hash>

options(same as parameter to translate function)

this function supports a Class in the options[:scope], ie:
     tx(:ueber, :scope => [Skyline::Page, :flashes])
  will try to translate this for Skyline::Page and all its parent classes (all descendants from AR)
  first try:                  translate(:ueber, :scope => [:page, :flashes])
  if that fails, it'll try:   translate(:ueber, :scope => [:article, :flashes])
  (note that the Skyline module is stripped)
if no Class is found, we'll fallback on the super function

Returns

<String>

the translation
