Get absolute URL for paperclip attachment

Question

Is it possible to get the absolute URI for a Paperclip attachment? Right now, the problem is that the production environment is deployed in a sub-URI (on Passenger: RackBa

Answer 1

You can do this:

<%= image_tag "#{request.protocol}#{request.host_with_port}#{@model.attachment_name.url(:attachment_style)}" %>

Or make a helper method to wrap it.

def absolute_attachment_url(attachment_name, attachment_style = :original)
  "#{request.protocol}#{request.host_with_port}#{attachment_name.url(attachment_style)}"
end

And use it like this:

<%= image_tag absolute_attachment_url(attachment_name, :attachment_style)}" %>

Ex: Model = Person (@person), attachment_name = avatar, style = :thumb

<%= image_tag absolute_attachment_url(@person.avatar, :thumb)}" %>
