Narabe.Ordered (Narabe v0.1.0)

A schema's order, declared once: the options of Narabe.Ecto that every call on the schema then takes.

defmodule MyApp.Board.Card do
  use Ecto.Schema

  schema "cards" do
    field :title, :string
    field :position, :string
    belongs_to :column, MyApp.Board.Column
  end

  use Narabe.Ordered, group: :column_id
end

defmodule MyApp.Docs.Page do
  use Ecto.Schema

  schema "pages" do
    field :title, :string
    field :kind, :string
    field :position, :string
    belongs_to :parent, __MODULE__
  end

  use Narabe.Ordered,
    group: :parent_id,
    tree: true,
    kind: :kind,
    rules: [nest: true, max_depth: 8, leaves: ["file"]]
end

Then Narabe.Ecto.move(Repo, Page, move) knows the rest, and an option given to a call wins over the schema's.

Options: those of Narabe.Ecto (:group, :tree, :position, :rules, :kind, :group_kind, :lock, :rebalance_at).
