Ruby Newbie - array/hash help

William Carpin

9/6/2006 2:47:00 PM

Given the following code...


my $ds = new DataSources($dbh);
my $data_sources = $ds->getTableNames();

foreach my $table_name (keys %{$data_sources}){
...some code...
}


Is there any effective way to reproduce the above foreach loop in Ruby?
I've been doing research, but I can't make heads or tails of it. Any
assistance would be greatly appreciated.

Wouldn't that just be:

data_sources.each_key do |table_name|
puts table_name
end

(I'm not real sure how the whole datasource/tablename thing works in
ruby, but I was assuming datasources was a Hash once you got it.)

Heh yeah, but he wanted '...some code...'... I just put something in
there that worked. I assumed he wanted something quite a bit more
complex than that and that he could figure out that's where it went ;)
