rake

Rake

• Avoid defining methods inside of Rake namespaces. This will define methods at the top level and interfere with things like factories. ^link

• Except in one offs, avoid defining new logic in rake tasks, use a class instead. ^link

  Example

  ## Bad
  namespace :users do
    desc "Decrements all users rank"
    task decrement_rank: :environment do
      User.where("rank > 0").update_all("rank = rank - 1")
    end
  end
  
  ## Good
  namespace :users do
    desc "Decrements all users rank"
    task decrement_rank: :environment do
      User.decrement_all_ranks
    end
  end
