Getting friends list with koala and fb api

I am trying to return a friends list with an uid of an authenticated user. however, I get only a partial return value, some friends are simply missing:

graph = Koala::Facebook::API.new(fb_token) friends = graph.get_connections("me", "friends") #some friend action

when i type

 friends.paging["next"]

in the browser it also returns an empty json array

  "data": [ ]

How am I doing this wrong and what is the right practice?

You need to get permission "user_friends" to get a list of friends, otherwise you will get empty data:

The friends field is available only for the User object after the user grants user_friends permission.

Try it for yourself: https://developers.facebook.com/tools/explorer?method=GET&path=me%2Ffriends&version=v2.5

So, with the right resolution, you can do:

 graph = Koala::Facebook::API.new(fb_token) result = graph.get_connections('me', 'friends')

for pagination:

 next_page = result.next_page

LAST, BUT NOT LESS:

Only users who install this application will return to API version 2.0 and higher. The total_count in the summary represents the total number of friends, including those who did not install the application. More details ...

You just try it.

It is very simple, you can get all your friends accounts in one line :)

 @graph = Koala::Facebook::API.new(facebook_token) @friends = @graph.get_connection("me", "friends",api_version:"v2.0").raw_response["summary"]["total_count"]
