FYI - .instance_methods is different in Ruby 1.9 vs 1.8

While working on PR https://github.com/theforeman/foreman/pull/1040, I was getting test failures with Ruby 1.8.7

It turns out that the method .instance returns an array of strings in Ruby 1.8.7 and an array of symbols in Ruby 1.9.3.

1.9.3 > Domain.instance_methods => [… , :hosts, :host_ids, :hosts=, :host_ids=, :hostgroups, :hostgroup_ids, :hostgroups=, :hostgroup_ids=,…]

1.8.7 > Domain.instance_methods => [… , "hosts", "host_ids", "hosts=", "host_ids=", "hostgroups", "hostgroup_ids", "hostgroups=", "hostgroup_ids=",…]

Just an FYI if you use this method in the future.

Regards,

Joseph

This distinction between 1.8.7 and 1.9.3 holds for any method that
return methods, including (from the top of my head): methods,
public_methods, etc
