use send_data for downloadable not working in Rails 5.0.0?

[Liz Huang]

Hi, 

Recently I just upgrade rails from 4.2.0 to 5.0.0, wonder what I need to do to

make send_data downloadable file working again? Now the data displayed in

page instead of downloadable file as before?

Thanks!

You need to post the bit of code that is failing so we can see what
you are doing. We are not telepathic. Not large chunks of code just
the bit that is failing. Tell us what you expect that bit of code to
do and what it actually does.

THe part of code is:

  def downloadCSV

    require 'csv'

    @ary = session[:ary]

    csv_string= CSV.generate do |csv|

        @ary.each do |t|

        csv << [t]

        end             

    end           

    send_data csv_string,

    type: 'text/csv; charset=iso-8859-1; header=present',

    disposition: 'attachment', filename: 'rannumgenerator.csv'

  end

The web applet link is:

You can enter 1000 for N and 13 for C, click compute, get a result page,

which has 

Download: CSV | Excel

the code above is used for downloading CSV file after click CSV, which works

in rails 4.2.0, now instead of showing the download dialog, all numbers displayed 

in the page.

Thanks!

Issue got fixed after I recreate the project after upgrading rails.
