ActiveCacher

Add this line to your application's Gemfile:

gem 'active_cacher'

And then execute:

$ bundle

Or install it yourself as:

$ gem install active_cacher

Module for caching results of method invocations. It's used as follows:

class A
  prepend ActiveCacher.instance
  instance_cache :foo_a, :foo_b
  rails_cache :foo_c

   def foo_a
     # some code
   end
   def foo_b
     # some code
   end
   def foo_c
     # some code
   end
end

Here return values of method calls foo_a and foo_b will be cached into instance variables @_foo_a and @__foo_b while result of method call foo_c will be both cached into instance variable @_foo_c and written to Rails cache.

Calling instance_cache :foo_a is roughly equivalent to the following code:

def foo_a
  @__foo_a ||= begin
    # some code
  end
end

And calling rails_cache :foo_c is roughly equivalent to the following code:

def foo_c
  @__foo_c ||= Rails.cache.fetch [self, :foo_c] do
    # some code
  end
end
