I prefer rails-ERD. annotate_models is also great.

  [6] pry(main)> c Account
  Columns for 'accounts'
    id                              :integer
    created_at                      :datetime
    updated_at                      :datetime
    address                         :string
    city                            :string
    state                           :string
    zip                             :string
    phone_number                    :string
    last_ip                         :string

  # Print formatted column names and type info for ActiveRecord models
  def fields(model)
    puts "Columns for '#{model.table_name}'"
    width = model.columns.inject(0) { |max_width, col| col.name.size > max_width ? col.name.size : max_width }
    _columns = model.columns.collect do |c|
      "  %-#{width + 2}s :%s" % [c.name, c.type]
    end.join("\n")
    puts _columns
  end

Instead of annotate models, I have a function in my .irbrc/.pryrc that will print out the columns for me when I'm in a rails console (I usually have one open almost all of the time). I prefer this to cluttering my model files. [6] pry(main)> c Account Columns for 'accounts' id :integer created_at :datetime updated_at :datetime address :string city :string state :string zip :string phone_number :string last_ip :string…
