Module: MigrationQueries::Migrater

Defined in:
lib/migration_queries/migrater.rb

Overview

Migrater is a module that extends the functionality of ActiveRecord migrations with logic to write SQL queries to files.

When included in a migration, it overrides the migrate method to write SQL queries to files after executing the migration.

Example:

class AddSomeTable < ActiveRecord::Migration[6.0]
include MigrationQueries::Migrater

def change
  create_table :some_table do |t|
    t.string :name
  end
end
end

=begin Migration Queries
CREATE TABLE some_table ("id" INTEGER PRIMARY KEY AUTOINCREMENT NOT NULL, "name" VARCHAR(255));
=end
