Instance Method Details

#cache!(key = nil, options = {}, &block) ⇒ Object

Caches the json constructed within the block passed. Has the same signature as the cache helper method in ActionView::Helpers::CacheHelper and so can be used in the same way.

Example:

json.cache! ['v1', @person], :expires_in => 10.minutes do
  json.extract! @person, :name, :age
end
