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

1. Generate Paperclip attachments

rails g paperclip person email_image rails g paperclip person telephone_image rake db:migrate

1. Include and use in your Models:

```ruby

class Person < ActiveRecord::Base …

has_attached_file :telephone_image, styles: “150x105>”, url: ‘/system/:class/:attachment/:id/:style/:filename’ has_attached_file :email_image, styles: “150x105>”, url: ‘/system/:class/:attachment/:id/:style/:filename’ include AttributeImagifiable attribute_imagifiable :telephone, as: :telephone_image attribute_imagifiable :email, as: :mail_image

``` This will automatically generate an image for the “telephone” and “email” attribute before each update, if that attribute changed.

attribute_imagifiable takes an optional :font parameter with path to a system ttf font. Default is “/usr/share/fonts/truetype/msttcorefonts/Verdana.ttf”.
