Installation

Add this line to your application's Gemfile:

gem 'activerecord-simple_index_name'

And then execute:

$ bundle

Or install it yourself as:

$ gem install activerecord-simple_index_name

Usage

When run rake db:migrate (or rake ar:migrate), index name will be automatically short.

Example

create_table :user_stocks do |t|
  t.integer :user_id,    null: false
  t.integer :article_id, null: false
  t.timestamps null: false
end

add_index :user_stocks, [:user_id, :article_id]
  • Index name without activerecord-simple_index_name : index_user_stocks_on_user_id_and_article_id
  • Index name with activerecord-simple_index_name : user_id_and_article_id

Development

After checking out the repo, run bin/setup to install dependencies. Then, run rake spec to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
