#cache!(key = nil, options = {}) ⇒ 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

    end

    merge! value
  else
    yield
  end
end

#cache_if!(condition, *args) ⇒ Object

Conditionally caches the json depending in the condition given as first parameter. 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_if! !admin?, @person, expires_in: 10.minutes do
  json.extract! @person, :name, :age
end
