no, my error
is relative to the dir where you start rails
if you use
ruby script/server
and
csv_data_dir = "public/data/csv"

Errata corrige
protected
def reload
logger.info "==> Reload in cvs_items_controller.rb -- RLM "
end
def get_csv_filenames_attributes
csv_data_dir = File.expand_path(File.dirname(__FILE__) +
"/../../public/data/csv/")
values = []
logger.info "==> csv_data_dir: #{csv_data_dir}"
Find.find(csv_data_dir) do |item|
next unless File.file?(item)
logger.info "==> file in csv_data_dir: #{item}"
values << item
end
values
end
I hope this is correct ;)
