defmodule App.Blog.Post do
  use Ash.Resource,
    domain: App.Blog,
    data_layer: Ash.DataLayer.AshPostgres,
    extensions: [AshObjectIds]

  object_id do
    prefix "p"
  end

  # .. data layer stuff

  actions do
    defaults([:read, :destroy, create: [:title], update: [:title]])
  end

  attributes do
    uuid_primary_key(:id)
    attribute(:title, :string, public?: true)
    # ... other attributes
  end
end

# Example:
