I would like to give visitors the option to download some pdf. I have tried:
<%= link_to "abc", "/data/abc.pdf"%>
<%= link_to "abc", "/data/abc.pdf", :format => 'pdf' %>
and some variations but they don't seem to work. I keep getting No route matches [GET] "/data/abc.pdf"
I have the pdf files in a folder called data, located in the assets folder. Any help would be appreciated.
Rails 4:
in routes:
get "home/download_pdf"
in controller (already have pdf):
def download_pdf
send_file(
"#{Rails.root}/public/your_file.pdf",
filename: "your_custom_file_name.pdf",
type: "application/pdf"
)
end
in controller (need to generate pdf):
require "prawn"
class ClientsController < ApplicationController
def download_pdf
client = Client.find(params[:id])
send_data generate_pdf(client),
filename: "#{client.name}.pdf",
type: "application/pdf"
end
private
def generate_pdf(client)
Prawn::Document.new do
text client.name, align: :center
text "Address: #{client.address}"
text "Email: #{client.email}"
end.render
end
end
in view:
<%= link_to 'Download PDF', home_download_pdf_url %>
Rails 3
The way to do it:
def download
send_data pdf,
:filename => "abc.pdf",
:type => "application/pdf"
end

File in public folder
This may the the answer to you: How to download a file from rails application
You should place your file in public folder, that is the trick.
Should work when the file is placed correctly.
Let me know if you can't move your file to public folder.
Download via controller
Create a controller with a downlaod action and link_to
it
def download
send_file '/assets/data/abc.pdf', :type=>"application/pdf", :x_sendfile=>true
end
