ruby on rails - Finding an Album's Artist with the Spotify API -

i'm trying use rails gem spotify api find artist(s) of particular album. start retrieving name of album such:

album_results = rspotify::album.search("the eminem show") 

to find artist of album issued following method variable above:

album_results.artists 

this returns ton of data don't need. want name of artist. able accomplish partially doing:

album_results.first.artists.first.name => "eminem" 

what i'd return name of available artists album results. tried using select method once again got data wanted:

album_results.select {|album| album.artists} 

what best approach accomplish this?

using select here return records artists.

you need use either collect or map

my_artists = album_results.flat_map{ |album|    album.artists.collect{|artist| artist.name} } 

edit

use flat_map returns flattened array default.

more efficient using collect , flatten!
