Migrate Rails: Add One Column to Multiple Tables

Question

Is there any special syntax for adding a timestamp column to multiple tables?

Answer 1

Not special purpose syntax, but you can certainly iterate over an array of table names and perform the same migration steps for each one.

class AddTimeStampsToABandC < ActiveRecord::Migration AFFECTED_TABLES = [:table_a, :table_b, :table_c] def self.up AFFECTED_TABLES.each do |t| add_timestamps(t) end end def self.down AFFECTED_TABLES.each do |t| remove_timestamps(t) end end end
