* Add version 4.2 to all existing migrationsjprovazn-versioned-migrationsJan Provaznik2018-11-221-1/+1
| | | | | | | | | DB schema generated by a migration may look different in rails 4 and 5 (because rails 5 may use different default values). For this reason it's important to explicitly set for which rails version a migration was written for. See https://stackoverflow.com/questions/35929869/activerecordmigration-deprecation-warning-asks-for-rails-version-but-im-no/35930912#35930912
* Add cop for use of remove_columnadd-remove-column-copSean McGivern2017-12-111-0/+1
| | | | | | | remove_column should only be used in the up (or change) step of a migration if it's a post-deployment migration. Otherwise there will be downtime due to the ActiveRecord column cache, which we can avoid by using the IgnorableColumn concern in combination with a post-deployment migration.
