We forgot to do so in commit fc757428e, when we upgraded rubocop-rails.
In this upgrade, this rule was changed to include the `change_column`
method.
Just like we did in commit df959b74f, I'm raising an
`ActiveRecord::IrreversibleMigration` exception in migrations done
before version 1.0.0, since making all of them reversible would be too
much work for little benefit.
There are some rules which only affect migration files, and we cannot
enable them if we're excluding those files from being inspected.
We're also changing migrations related to the Rails/TimeZone rule
slightly because these fields were already changed afterwards, so we
aren't changing the schema.
DEPRECATION WARNING: Directly inheriting from ActiveRecord::Migration
is deprecated. Please specify the Rails release the migration was
written for:
class MigrationClass < ActiveRecord::Migration[4.2]
(called from require at bin/rails:4)
