I'm tying to show active user names using this code:
<%= User.count(:activeuser, :distinct => true, :group => 'name') %> currently it showing this ugly result:
{"Webster"=>0, "Wilfrid"=>0, "Winifred"=>0, "Nicolas"=>1, "Cage"=>1} how can i make this pretty? like showing only true users Nicolas and Cage
If you want to filter a Hash to include only items that meet particular criteria, use Hash#select:
hsh = {"Webster"=>0, "Wilfrid"=>0, "Winifred"=>0, "Nicolas"=>1, "Cage"=>1} hsh.select {|key, val| val > 0 } # => {"Nicolas"=>1, "Cage"=>1} ...or, to exclude items, Hash#reject:
hsh.reject {|key, val| val.zero? } # => {"Nicolas"=>1, "Cage"=>1}
