I am trying to supplement and ultimately provide a patch for 'foreman' which is
an adjunct to puppet.
Essentially, there is a Hosts class which belongs_to Hostgroup and Hostgroup
class has a column called 'ancestry' which is actually a Hostgroup (probably
what is referred to as STI but I am not sure) and thus within Foreman, nesting
Hostgroups is not uncommon.
Thus I could have a Host that is called "ServerA", that belongs to "WebServer"
Hostgroup which has an ancestry (Hostgroup) called "Base" and for me to find
out all of the puppetclasses that host "ServerA" belongs to, I would have to
get a listing of all of the puppetclasses within the chain of Hostgroups to
which ServerA belongs.
So this is my code...
@hosts.each do |host|
@ancestors = Hostgroup.find(host.hostgroup.ancestry) unless
host.hostgroup.ancestry == nil
@ancestors.puppetclasses.each do |anc|
@my_classes[anc.name] += 1
end
end
And this works for me because I am only nesting 1 level but it's conceivable
that other users would nest many more levels and if my patch is to be accepted,
I undoubtedly have to account for an infinite level of nesting.
How would I accomplish that?
