My facebook application has a tab the user can install. On this tab, there is links that are suppose to link to application canvas (ex.: apps.facebook.com/my-app).
It seems that when I'm on my user profile tab and click on a link, Facebook loads the page inside the tab. How do I force it to navigate out of the tab and into the canvas page?
You need to use full urls instead of relative urls.
For example:
<a href="/apppage/content.php">Link</a> -> Renders on tab
<a href="http://apps.facebook.com/yourapp/apppage/content.php">Link</a> -> Renders application page
Good luck!
You can also use the regular rails 'link_to' function and pass :only_path => false. This will add the host to your URL which will be your app's canvas page. When you click it within a Facebook tab, you will go to the app's canvas page instead of staying in the tab.
<%= link_to "Leave the tab", :controller => 'home', :only_path => false %>
