Create a unique file path using Polymorphic Paperclip

Question

I am having a problem with different users uploading files with the same name that are being overwritten by the Polymorphic Paperclip plugin. What I would like to do is enter the current user id in the URL / path. Is it possible? Would I be better off generating a random name?

Here are my current values: url and: path in asset.rb:

:url => "/assets/:id/:style/:basename.:extension",
:path => ":rails_root/public/assets/:id/:style/:basename.:extension"

What I would like to do is the following:

:url => "/assets/#{current_users_id}/:id/:style/:basename.:extension",
:path => ":rails_root/public/assets/#{current_users_id}/:id/:style/:basename.:extension"

Answer 1

Use bond interpolation:

config / initializers / paperclip.rb file:

module Paperclip
  module Interpolations
    def user_id(attachment, style)
      current_user.id
    end
  end
end

has_ attach_file:

:url => "/assets/:user_id/:id/:style/:filename"

( Paperclip 2.x 2.3;: ; , .)

bypaperclip.rb, :

:

  Paperclip.interpolates :user_id do |attachment, style|
    attachment.instance.user_id
  end

    :url => "/Microposts/:user_id/:style/:basename.:extension"
