  • 0

I’m working with the Koala gem and the Facebook Graph API, and I want to break down the results I get for a users feed into separate variables for inserting into a mySQL database, probably using Active Record. Here is the code I have so far:

@token = Service.where(:provider => 'facebook', :user_id => session[:user_id]).first.token
@graph = Koala::Facebook::GraphAPI.new(@token) 
@feeds = params[:page] ? @graph.get_page(params[:page]) : @graph.get_connections("me", "home")

And here is what @feeds looks like:

    [{"id"=>"1519989351_1799856285747", "from"=>{"name"=>"April Daggett Swayne", "id"=>"1519989351"},

I have looked around for clues on this, and haven’t found it yet (but I’m still working on my stackoverflow-foo). Any help would be greatly appreciated.

    That isn’t a Ruby Hash, that’s a fragment of a JSON string. First you need to decode into a Ruby data structure:

    # If your JSON string is in json...
h = ActiveSupport::JSON.decode(json) # Or your favorite JSON decoder.

    Now you’ll have a Hash in h so you can access it like any other Hash:

    array = h['data']
puts array[0]['id']
# prints out 1111111111_0000000000000
puts array[0]['from']['name']
# prints Jane Done
