Schema macros for soft-delete-enabled Ecto schemas.

This is the schema-facing part of Lazarus. Use it in any schema that should carry soft-delete fields or schema-level deletion metadata.

What it provides

• soft_deletes/1 - adds the deleted_at field and optional deletion_reason field
• @soft_deletes_opts - module-level defaults for soft_deletes/1
• @hard_delete_on_cascade - associations that should hard-delete during parent cascades
• @hard_delete_on_replace - associations that should hard-delete during on_replace flows

Example

defmodule MyApp.Post do
  use Ecto.Schema
  use Lazarus.Schema

  schema "posts" do
    soft_deletes()
  end
end

Module defaults

Configure defaults for every soft_deletes/1 call in the module:

@soft_deletes_opts [
  include_reason: true,
  deleted_at_type: :utc_datetime_usec
]

schema "posts" do
  soft_deletes()
end

Per-call options

schema "posts" do
  soft_deletes(
    include_reason: true,
    deleted_at_type: :utc_datetime_usec
  )
end

The exact cascade and association-replacement rules are covered in the "Cascade Soft-Deletes" and "Assoc Replace" guides.
