Subject: Re: Beginners question about Array#assoc

Actually, I am still having trouble.  My code is:

res = dbh.query("SELECT tag ...blah blah")
masters = Array.new
res.each_hash do |row|
  p row["tag"]

  if masters.assoc(row["tag"])
    newMaster = { "subtags" => Array.new, "master" => 'a' }
    masters.push [row["tag"], newMaster]
  end
  .....

And here is my output:


"852"
./prep_tags_yaml_02.rb:65: undefined method `[]' for nil:NilClass 
(NoMethodError)
        from ./prep_tags_yaml_02.rb:8


I tried populating the "masters" array with an init line like:

masters = [["asdf", "agf"], ["bb", "behe"]]

and it works, but this doesn't help as the array has top be empty to 
begin with.  Puzzling...
