Rails - Oct 2010 - [Newbie] Require old password when changing it (Rails 3).

Hello!

I''m trying to create a user update action, and I want to check so that
the user has entered his correct old password before changing it. I''ve
been googeling for a while but I can''t find any good tips.

I''m thinking of adding a ''old password'' column to my
User model but I
don''t know if thats necessary.

My current update action locks like this:

def update
    @user = User.find(params[:id])

    if @user.update_attributes(params[:user])
      flash[:success] = "Din profil har uppdaterats."
      redirect_to @user
    else
      @title = "Redigera profil"
      render ''edit''
    end
end

I''ve tried a couple of things whiteout good result.

Any general tips would be greatly appreciated.

Thanks
// Anders
