I am not sure if I should be answering since I seem to be
even denser than usual but to me it looks like you are
trying to assign the contents of a file to a variable
named after the file, is that right? This might work:

files = {}
Find.find("#{ENV[DOCUMENT_ROOT]}/data") do |path|
  if path =~ /.yml$/
    File.open path do |file|
      # #eval or #instance_variable_set should work here, too
      files[file.basename[0...-4]] = YAML.load file
    end
  end
end
