# Global positioning

defmodule MyModel do

  use Ecto.Schema

  import EctoOrdered

  schema "models" do

    field :position, :integer, virtual: true

    field, :rank, :integer

  end

  

  def changeset(model, params) do

    model

    |> cast(params, [], [:position])

    |> set_order(:position)

  end

end

# Scoped positioning

defmodule MyModel do

  use Ecto.Model

  use EctoOrdered, scope: :reference_id

  schema "models" do

    field :reference_id, :integer

    field :position,     :integer, virtual: true

  end

  

  def changeset(model, params) do

    model

    |> cast(params, [], [:position, :reference_id])

    |> set_order(:position, :reference_id)

  end
