Ruby on Rails

Hi all, 

from last 1 hour i am facing one problem.

I have written a code for creating  user and show them in index page after save.

Code is working perfectly but on index page i am getting all record till second last record saved, but i am not getting current  record which is saved.

But in database my last record is saved successful.

But when i restart the server , than on index page all record come with the last record .

I dont know why this all is happening ?

Code below

######## controller code

class AdminUsersController < ApplicationController

  def new

    @admin = AdminUser.new

  end

  def index

    @admins = AdminUser.all

  end

  def create

    @admin = AdminUser.new(params[:admin_user])

    if @admin.save

      redirect_to admin_users_path

    else

      render "new"

    end

  end

end

######## new view############

<%= form_for @admin do|f|%>

First Name

<%= f.text_field :first_name%>

<%= submit_tag"Create"%>

<% end %>

######## index view############

<%= @admins%>

##############model

nothing in model

Hope you all understand the problem .

Thanks
