OneOff

This gem allows you to run code that's needed for one time use. This can be deleting/editing specific records, moving data between old and new columns, and a variety of other uses.

Generate a one_off:

$ rails/rake one_off g ${name of file}

It should be generated in the db/one_off directory. It'll look something like 20230508202324_one_off_name.rb

This will give you a file where you can add code to the #perform method.

require 'one_off/environments'

module OneOff
  class OneOffName
    include Environments

    environments :development, :production

    def perform
      #add task into here
    end
  end
end

To run this one_off locally, use the matching task

$ rails/rake one_off:matching\[name_of_one_off\]

To have this run in production, you'll want to add this line to your build script. This will run all the one_offs that do not exist in the one_off_tasks database table.

$ bundle exec rake db:migrate one_off:run

Add this line to your application's Gemfile:

gem 'one_off'

And then execute:

$ bundle

Or install it yourself as:

$ gem install one_off

This gem requires a database table to track the one_offs that have already been run. Run the generate migration:

$ rails/rake one_off:install:migrations

This will create a new migration file in your main app. You'll need to run migrations for this to take place:

$ rails/rake db:migrate
