Can ActiveRecord create tables outside of a migration?

Question

I am working on a non Rails web app, so no migrations script by default.

The Sequel ORM lets me create tables easily in a script:

#!/usr/bin/env rub         


        

Answer 1

My current understanding is no, all modifications data or schema have to be done through a migration. I have a complete rakefile on github which can be used to perform the migrations outside of Rails.

Alternatively if it is just an initialisation script the following could be used.

ActiveRecord::Base.establish_connection(
   :adapter   => 'sqlite3',
   :database  => './lesson1_AR.db'
)

ActiveRecord::Migration.class_eval do
  create_table :posts do |t|
        t.string  :title
        t.text :body
   end

   create_table :people do |t|
      t.string :first_name
      t.string :last_name
      t.string :short_name
   end

   create_table :tags do |t|
      t.string :tags
   end 
end
