Dear Rubyists,

I just lost a contract because of my code in a Rails project.

The specific code in question is related to a "posting a comment" feature. Here are the details:

In this project, "posting a comment" does not simply entail inserting a row into the database. It involves a procedure to yes, insert a row, but also detect its language, check for spam, send emails, and "share" it to Twitter and Facebook. I believe this algorithm should be encapsulated. I do not believe it belongs in a controller or a model. I do not believe Active Record callbacks should be used.

The "senior developer", whom is the stake holder's right hand man, said this:

def find_in_batches(model)
  current_batch, count = 0, model.count

  while count > 0 do
    model.all.skip(current_batch * 1000).limit(1000).each do |doc|
      yield doc  
    end
    count -= 1000
    current_batch += 1
  end

  ConnectionFailure = Class.new(StandardError)

  def self.perform(data)
    new(data).perform
  end

  def initialize(data)
    @data = data.symbolize_keys
    @account = Account.find(@data[:account_id])

    @array = array
    @flat_array = []
