method_caching

method_caching is a simple Ruby library for caching instance method of a class (using Rails.cache as cache store)

  gem install method_caching

or add to Gemfile

  gem "method_caching"

class User < ActiveRecord::Base
  method_caching

  def full_name
    "#{first_name} #{last_name}"
  end
  cache_method :full_name, clear_on: :save # Clear cache for method full_name whenever method 'save' is called
end

class User
  include MethodCaching::Generic
  method_caching

  def full_name
    "#{first_name} #{last_name}"
  end
  cache_method :full_name, clear_on: :save # Clear cache for method full_name whenever method 'save' is called
end

By default, method_caching will use the record's id as the default identifier to generate the cache key. You can change the default identifier by passing custom identifier

class User < ActiveRecord::Base
  method_caching :custom_identifier
end

• Check out the latest master to make sure the feature hasn't been implemented or the bug hasn't been fixed yet.
• Check out the issue tracker to make sure someone already hasn't requested it and/or contributed it.
• Fork the project.
• Start a feature/bugfix branch.
• Commit and push until you are happy with your contribution.
• Make sure to add tests for it. This is important so I don't break it in a future version unintentionally.
• Please try not to mess with the Rakefile, version, or history. If you want to have your own version, or is otherwise necessary, that is fine, but please isolate to its own commit so I can cherry-pick around it.
