Ruby on Rails 입니다

간단한 것인데 초보자가 개념없이 접근하다보니 막혔습니다..

샘플로 하나 만든것인데,
http://crud-vxade.run.goorm.io/board
입력칸에 가장 최근에 입력된 값이 불러들여지도록 하고 싶은데 방법을 못 찾고 있네요...

board_controller.rb

class BoardController < ApplicationController
  def index
	  @posts = Post.all
  end
	
	def create
		@post = Post.includes(:comments).order("created_at desc").limit(1).offset(0)
		title = params[:title]
		content = params[:content]
		updated_at = params[:updated_at]
		lee = params[:lee]
	
		Post.create(title: title, content: content, updated_at: updated_at, lee: lee)
		redirect_to '/board'
	end 
	
	def edit
		@post = Post.find(params[:id])
	end
		
	def update
		@post = Post.find(params[:id])
		@post.title = params[:title]
		@post.content = params[:content]
		
		@post.lee = params[:lee]
		@post.save
		redirect_to '/board'
	end
	
	def delete
		@post = Post.find(params[:id])
		@post.destroy
		redirect_to '/board'

	end
end

routes.rb

Rails.application.routes.draw do 
	
	get '/board', to: 'board#index' 
	post '/create', to: 'board#create' 
	get '/edit', to: 'board#edit' 
	post '/update', to: 'board#update' 
	get '/delete', to: 'board#delete'
