Results from "comments" request are sometimes Arrays instead of Hashes

[bradical]

Hi, I've run into a strange issue that could be related to Facebook's Graph API or could be related to this gem.

Basically, when I make a request for a post's comments, sometimes I get a Hash and other times I seem to get an array. The code that makes the request and processes the comment is below.

The reason I know this is what's happening is that I'm getting an error on this line: from = comment["from"] about how I can't convert String to Fixnum so I'm assuming that the comment object is an indexed Array at that point.

You can see that I've added some code that will skip comments that aren't Hashes to avoid this problem but I'm curious about why it might be happening.

Thanks!

def read_feed
  client.object("#{self.facebook_page_id}/feed").each do |item|
    next unless item.is_a?(Hash)
    message = do_something_with_feed_item_hash(item)

    client.object("#{item["id"]}/comments").each do |comment|
      next unless comment.is_a?(Hash)
      do_something_with_comment_hash(comment)
    end
  end
end

def do_something_with_comment_hash(comment)
  from = comment["from"]
end
