in rails, how to return records as a csv file

Question

I have a simple database table called \"Entries\":

class CreateEntries < ActiveRecord::Migration
  def self.up
    create_table :entries do |t|
      t.st         


        

Answer 1

The following approached worked well for my case and causes the browser to open the appropriate application for the CSV type after downloading.

def index
  respond_to do |format|
    format.csv { return index_csv }
  end
end

def index_csv
  send_data(
    method_that_returns_csv_data(...),
    :type => 'text/csv',
    :filename => 'export.csv',
    :disposition => 'attachment'
  )
end
