How to encode media in base64 given URL in Ruby

Question

I\'m trying to upload an image to PingFM. Their documentation says:

media – base64 encoded media data.

I can access this image via the URL.

Answer 1

Here's my solution:

1: Put this custom image_tag method into ApplicationHelper, and include ActiveSupport module

module ApplicationHelper
  include ActiveSupport
  def image_tag_base64(file_path, mime_type = 'image/jpeg', options = {})
    image_tag("data:#{mime_type};base64,#{Base64.encode64(open(file_path) { |io| io.read })}", options)
  end
end

2: Then, inside the view you want to use base64 encoded image use the method like this:

<%= image_tag_base64 @model.paperclip_attribute.path(:size), @model.paperclip_attribute.content_type, {class: 'responsive-img etc etc'} %>
