Renaming enums

[lleger]

In our app, we renamed a model and so the enum needed to be changed as well:

ModelName -> NewModelName ModelTypeEnum ->NewModelTypeEnum

Is there a good way to rename enums? Currently, we're creating a new enum definition entirely and migrating the PG columns manually.

That's how to do it currently. There're no helpers in EctoEnum for handling at the moment.

For reference in case someone comes here looking for an answer, here's how we did it with an Ecto migration:

defmodule MyApp.Repo.Migrations.ChangeFooEnumToBarEnum do
  use Ecto.Migration

  def up do
    execute("ALTER TYPE foo_enum RENAME TO bar_enum")
  end

  def down do
    execute("ALTER TYPE bar_enum RENAME TO foo_enum")
  end
end
