How to download a CSV file in Ruby on Rails?

Question

In my InvoicesController I have this:

def index
  @invoices = current_user.invoices
  respond_to do |format|
    format.html
    format.xls
    form         


        

Answer 1

Try specifying the appropriate content headers and explicitly rendering your index.csv.erb template in your format.csv handler block.

# app/controllers/invoices_controller.rb
format.csv do
    response.headers['Content-Type'] = 'text/csv'
    response.headers['Content-Disposition'] = 'attachment; filename=invoice.csv'    
    render :template => "path/to/index.csv.erb"
end
