Question

I’m using the omniauth gem with rails and it works great with loging in users, but everytime it takes you to the fb login page then redirects you back. I was wondering if there is a way to do what most pages do and show the fb login in a popup and then reload the parent div once that is complete. Any ideas?

Thanks!

Sure, you can easily.

In your view:

=link_to "Log in with Facebook", omniauth_authorize_path(:user, :facebook), :class => "popup", :"data-width" => 600, :"data-height" => 400

In your application.js:

function popupCenter(url, width, height, name) {
  var left = (screen.width/2)-(width/2);
  var top = (screen.height/2)-(height/2);
  return window.open(url, name, "menubar=no,toolbar=no,status=no,width="+width+",height="+height+",toolbar=no,left="+left+",top="+top);
}

$("a.popup").click(function(e) {
  popupCenter($(this).attr("href"), $(this).attr("data-width"), $(this).attr("data-height"), "authPopup");
  e.stopPropagation(); return false;
});

And then in your callback view:

:javascript
  if(window.opener) {
    window.opener.location.reload(true);
    window.close()
  }

This’ll pop up your Facebook auth in a centered 600×400 popup, then when the user returns from authentication, the view will close the popup and refresh the parent page. It degrades gracefully if a user ctrl-clicks the link, or doesn’t have Javascript enabled, too.
