Timestamp service configuration

Used by decidim-initiatives.

Provide a class to generate a timestamp for a document. The instances of this class are initialized with a hash containing the :document key with the document to be timestamped as value. The instances respond to a timestamp public method with the timestamp.

An example class would be something like:

class MyTimestampService
  attr_accessor :document
  def initialize(args = {})
    @document = args.fetch(:document)
  end
  def timestamp
    # Code to generate timestamp
    "My timestamp"
  end
end

class MyTimestampService
  attr_accessor :document

  def initialize(args = {})
    @document = args.fetch(:document)
  end

  def timestamp
    # Actual code to add the timestamp
  end
end

The arguments provided for the initialize method are:

document - The document that needs to be timestamped

Then you will need to configure it with the help of Environment Variables:

export DECIDIM_TIMESTAMP_SERVICE="MyTimestampService"
