FacebookScraper

You're hosting OpenGraphObjects for Facebook? Ever noticed, when you updated your objects, Facebook won't recognize these changes?

According to FacebookDocs, they will scrape "Every 7 days after the first scrape". So, lets force a scrape earlier.

FacebookScraper for the rescue!

Installation

Add this line to your application's Gemfile:

gem 'facebook_scraper'

And then execute:

$ bundle

Or install it yourself as:

$ gem install facebook_scraper

Example

FacebookScraper.trigger_with(url_to_your_open_graph_object)

Example (Using Rails)

class AvatarsController
  after_action :trigger_facebook_scraper, only: [:update]

  # ...

  private

  # NOTE: The `background do ... end` part is optional
  def trigger_facebook_scraper
    background do
      FacebookScraper.trigger_with(url_for(@avatar))
    end
  end

  # Run a piece of code in parallel
  def background
    Thread.new do
      yield
      ActiveRecord::Base.connection.close
    end
  end

  # ...
end
