Support for enums in Rails 7

[jwg2s]

This tripped us up trying to upgrade to Rails 7, where the enum_types were duplicated by however many schemas you had. The following monkey patch will get you past it, at least until you figure out how to stop using apartment entirely!

Values Returned Before

create_enum "status", ["not_started", "not_started", "not_started", "in_progress", "in_progress", "in_progress", "complete", "complete", "complete"]

Monkeypatch

module ActiveRecord
  class Base
    class << self
      def connection_with_enum_types_patch
        patched_connection = connection_without_enum_types_patch

        def patched_connection.enum_types
          super.map do |name, value|
            [name, value.split(",").uniq.join(",")]
          end
        end

        patched_connection
      end

      alias_method :connection_without_enum_types_patch, :connection
      alias_method :connection, :connection_with_enum_types_patch
    end
  end
end

Values Returned After

create_enum "status", ["not_started", "in_progress", "complete"]
