I've build a community using rails 3.2, ruby 1.9.3, mongoid and it's all hosted on heroku on a cedar stack - www.Meer.li.
The problem I have now, is that facebook doesn't register my opengraph meta tags at all! I've tried to run it through - http://developers.facebook.com/tools/debug/og/object?q=http%3A%2F%2Fmeer.li%2F - and it doesn't even see them. I'm at a total loss here and can't find any answers.
Hope you can help.
On your page, you have your Open Graph object type set to activity as shown below:
<meta property="og:type" content="activity" />
No Open Graph object schema exists for this type, which is likely the source of your problem. You can verify that here: http://graph.facebook.com/schema/og/activity.
Some common Open Graph object types have been pre-defined, and are documented at http://ogp.me/#types. Alternatively, you may define custom objects with custom attributes by creating a new object type of your choosing, and these should be namespaced in the form my_namespace:my_type.
I would recommend trying one of the predefined object types, such as website. Assuming that that fixes your problem, but you require more custom behavior, then move on to defining a custom, namespaced object type with custom fields of your choosing.
