Count the length (number of lines) of a CSV file?

Question

I have a form (Rails) which allows me to load a .csv file using the file_field. In the view:

    <% form_for(:upcsv, :html => {:multipa         


        

Answer 1

CSV.foreach(file_path, headers: true).count

CSV.read(file_path).count
