Ruby Patterns
# Metaprogramming
class BaseService
def self.inherited(subclass)
define_method(subclass.name.underscore) do |**args|
klass = Object.const_get(subclass.name)
klass.new(**args).execute
end
end
end
# Blocks and yield
def with_transaction
ActiveRecord::Base.transaction do
yield
rescue => e
rollback!
raise e
end
end
# Rails patterns
class UsersController < ApplicationController
before_action :set_user, only: [:show, :update]
def index
@users = User.all.page(params[:page])
render json: @users
end
private
def set_user
@user = User.find(params[:id])
end
end
