One Offs

Track and manage your one off scripts, in rails applications.

Can be used to move stuff out from your rails migrations that dont belong there. For example data migrations can be moved from schema and into one-offs.

Add this line to your application's Gemfile:

gem 'one_offs'

And then execute:

$ bundle

Or install it yourself as:

$ gem install one_offs

After installing the gem, In your Rakefile (/Rakefile) add the following line

require 'one_offs/tasks'

And setup a tracker table (creates migration).

rake one_offs:generate_tracker_table

OR using SQL query if you want to avoid a migration (Useful if you need to setup one off tasks before db:migrate).

rake one_offs:create_tracker_table_using_sql

Add scripts to lib/one_offs/

• File name should be <number>_class_name_inside_file.rb (Rails convention for file name to class name with the order number before that)

  Example:

  File: 1_hello_world.rb
  Contents:
      class HelloWorld
          def self.process
          puts("You may write your code in this process method").
      end
  end
  

To run pending one_off scripts.

rake one_offs:run

To baseline one_offs seed them into to the tracker table.
