Inherited Resources



Why?

• Makes writing boilerplate controllers easier

• Easy internationalization of flash text with the Responders gem

• Easy API generation for JSON and XML



Why Not?

• Another DSL/Library to Learn

• Can sometimes get in your way for nonstandard controller actions

• Not good for beginners - feel the pain of repetition in your controllers, first



class AccountsController < ApplicationController respond_to :json inherit_resources #gives you all RESTful actions for Accountend



Kaminari



Why?• Easily customizable/themed

• great configuration options

• awesome generators

• Scope-Based

• Doesn’t hack core objects

• I18n ready for localization



Why Not?

• Other engines might express alternative decisions (refinery, ie)

• Can be painful to paginate non-scope/AREL collections



#in your controller@users = User. page(params[:page]). per(50)

#in your view<%= paginate @users %>



guard



Why?

• Don’t constantly have to run tests manually

• Invokes tests for files that change

• Extensible plugin architecture

• Extensible notification architecture



Why Not?

• Minor issue where guard plugins can lag behind on dependencies



Configatron



Why?

• Easy, dynamic configuration for gems and applications

• Configure via manual code, hash or YAML

• Plays nicely with Rails Application configuration



Why Not?

• nulls vs. blanks can be confusing



module Facebook def self.secret_key=(key) configatron.facebook.secret_key = key end

def self.secret_key configatron.facebook.secret_key endend



Bourbon



Why?

• Handy shortcuts for common CSS idioms

• Beautiful documentation

• Exposes you to lots of great/creative CSS uses



Why Not?

• Can be difficult to install/configure as part of the asset pipeline

• You still need to be an informed consumer of experimental CSS features
