Ruby on Rails

hi guys:

I'm scratching my head on this one: I have a twitter app where I'm
trying to open a modalpopup with a twitter sign in, get them to sign in,
then close the popup and refresh the main window. My code however
refreshes the main window with the popup window result, which I thought
was really strange:

application.html.erb

function OpenModalPopUP()
{
window.showModalDialog('/sessions/create');
}

main page

<%= link_to "login via twitter", {:controller => "sessions/create"},
:onclick => "OpenModalPopUP()" %>

sessions/create

def create

oauth.set_callback_url(finalize_session_url)

session['rtoken'] = oauth.request_token.token
session['rsecret'] = oauth.request_token.secret

redirect_to oauth.request_token.authorize_url
end

sessions/finalize

def finalize
oauth.authorize_from_request(session['rtoken'], session['rsecret'],
params[:oauth_verifier])

session['rtoken'] = nil
session['rsecret'] = nil

profile = Twitter::Base.new(oauth).verify_credentials
user = User.find_or_create_by_screen_name(profile.screen_name)

user.update_attributes({
:atoken => oauth.access_token.token,
:asecret => oauth.access_token.secret,
})

sign_in(user)
# page << "window.close()"
redirect_to session[:return_to] rescue redirect_to :controller =>
"home"
# redirect_to :controller => "sessions/autoclose"
end

As you can see, by the commented out code, I attempted to push
"window.close()" but it gave me an error message. i then tried to
redirect to another window which autoclosed, but when I did that, it
redirected the main window to autoclose as well. I'm a rails noob, so
I'm guessing that i have to do something after the redirect to shut
down the process after closing the window, otherwise it will run the
refresh on the main window? Please advise.

also, while i'm at it, do you know how I can resize the modalpopup?

Thanks...chris
