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
# File lib/jbuilder/jbuilder_template.rb, line 51 def cache!(key=nil, options={}, &block) if @context.controller.perform_caching value = ::Rails.cache.fetch(_cache_key(key, options), options) do _scope { yield self } end merge! value else yield end end
cache_if!(condition, *args) { || ... }

Conditionally catches 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
# File lib/jbuilder/jbuilder_template.rb, line 72 def cache_if!(condition, *args, &block) condition ? cache!(*args, &block) : yield end
