Migration macros for adding the columns expected by Lazarus.Schema.

Use this module inside create table(...) or alter table(...) blocks to add the deleted_at column and optional deletion-reason column that your schemas expect.

Example

use Lazarus.Migrations

create table(:posts) do
  soft_deletes()
end

You can also use the helper inside alter table(...).

Per-call options

soft_deletes(
  include_reason: true,
  deleted_at_type: :utc_datetime_usec
)

Repo configuration

Defaults can be configured per migration Repo:

config :my_app, MyApp.Repo,
  migration_soft_deletes: [
    include_reason: true,
    deleted_at_type: :utc_datetime_usec
  ]

soft_deletes/1 merges repo-level defaults with the per-call options, with per-call values taking precedence.

Keep migration and schema helpers aligned so the columns added here match the fields declared with Lazarus.Schema.
