AttributeImagifiable

Using paperclip to generate images from sensible attributes like e-mails and telephone numbers, in order to reduce crawler's success

Installation

Add this line to your application's Gemfile:

gem 'attribute_imagifiable'

And then execute:

$ bundle

Or install it yourself as:

$ gem install attribute_imagifiable

Usage

include and use in your Models:

class Person < ActiveRecord::Base
...

  has_attached_file :telephone_image,
                    styles: {small: "150x105>"},
                    url: '/system/:class/:attachment/:id/:style/:filename'
  has_attached_file :mail_image,
                    styles: {small: "150x105>"},
                    url: '/system/:class/:attachment/:id/:style/:filename'
  include AttributeImagifiable
  attribute_imagifiable :telefon, as: :telephone_image
  attribute_imagifiable :email, as: :mail_image

This will automatically generate an image for the "telefon" and "email" attribute before each update, if that attribute changed.

IMPORTANT: Use and generate paperclip attachments and attributes before
