Post Redirect Get pattern in Rails

Question

How can I implement PRG in Rails?

I used PRG in Rails, but I am not totally convinced it\'s right. I was wondering is there any better way to handle it in Rails?

Answer 1

use below code

class UsersController < ApplicationController

  def new
    @user = User.new(session[:user_param])
   session[:user_param]=nil
  end

  def create

    @user = User.new(params[:user])

    if @user.save
      # clears previously stored user if there is any
      flash.discard(:user)
      redirect_to '/'
    else
      session[:user_param] = @user
      redirect_to :action => :new
    end

  end

end
