Can I generate a ruby on rails database migration file from a MySQL sql file

Question

I have a sql script file that upon import creates a table in a MySQL database and fills it with 2800 record. These are all the postal codes for the country Belgium.

Answer 1

If your config/database.yml is referencing the MySQL database with the schema, then do

rake db:schema:dump

That will create a db/schema.rb file which is database independent.

Copy schema.rb into db/migrate/001_original_schema.rb:

class OriginalDatabaseMigration < ActiveRecord::Migration
  def self.up
    # schema.rb here
  end

  def self.down
    # drop all the tables
  end
end
