RuboCop Migrations

Rails migrations analysis as a extension of RuboCop. Heavily inspired by rubocop-cask which in turn is inspired by rubocop-rspec.

Just install the rubocop-migrations gem

gem install rubocop-migrations

or if you use bundler put this in your Gemfile

gem 'rubocop-migrations'

You need to tell RuboCop to load the Migrations extension. There are three ways to do this:

Put this into your .rubocop.yml:

require: rubocop/migrations

Now you can run rubocop and it will automatically load the RuboCop Migrations cops together with the standard cops.

rubocop --require rubocop/migrations

All cops are located under lib/rubocop/cop/migrations, and contain examples/documentation.

In your .rubocop.yml, you may treat the Cask cops just like any other cop. For example:

Migrations/RemoveIndex:
  Enabled: false

1. Fork it
2. Create your feature branch (git checkout -b my-new-feature)
3. Commit your changes (git commit -am 'Add some feature')
4. Push to the branch (git push origin my-new-feature)
5. Create new Pull Request

We use Appraisals in order to run the tests with different rubocop versions to ensure compatibility.

To run the specs with all supported rubocop versions first install the required dependencies with:

bundle exec appraisals install

Then run the specs by just running rake it will run specs with all the versions.

For more info just check the appraisals documentation https://github.com/thoughtbot/appraisal
