Setelah seharian googling, akhirnya aku dapat sedikit pencerahan mengenai sript login pake rails versi 1.2.3 meskipun masih tanpa enkripsi. Secara umum seperti berikut :

Pertama adalah Login Controller

class LoginController < ApplicationController

def index
end

def login
end

def cek_login

if request.post?
if @session[”user”] = User.authenticate(params[:login][:name],params[:login][:password])
flash[:notice] = “Login Sukses!”
redirect_to :action => “index”
else
if params[:login][:name] == “”
flash[:notice] = “Username belum diisi.”
elsif params[:login][:password] == “”
flash[:notice] = “Password belum diisi”
else
flash[:notice] = “Username atau password salah”
end
redirect_to :action => “login”
end
end
end

end
