Helpers

Readability

• annotate_models - Automatically generates attributes as comments at the top of files to see what attributes are in models, fixture files, specs, factories, and more. Example:

  # == Schema Info
  #
  # Table name: line_items
  #
  #  id                  :integer(11)    not null, primary key
  #  quantity            :integer(11)    not null
  #  product_id          :integer(11)    not null
  #  unit_price          :float
  #  order_id            :integer(11)
  #
  
   class LineItem < ActiveRecord::Base
     belongs_to :product
  # ...

Migrations

• strong_migrations - Detect potentially dangerous migrations and prevent them from running by default, along with instructions on safer ways to do what you want.

• native_enum and activerecord-postgres_enum for backing Rails enums (which are application-only) by database enums, so people looking at the database can actually understand what all those integer values actually mean.

View Helpers

Rails already provides a ton of view helpers (e.g. number_to_currency), they're listed here.
