A postgresql datalayer for the Ash Framework

AshPostgres

AshPostgres supports all capabilities of an Ash data layer, and it will most likely stay that way, as postgres is the primary target/most maintained data layer.

Custom Predicates:

• AshPostgres.Predicates.Trigram

DSL

See the DSL documentation in AshPostgres.DataLayer for DSL documentation

Usage

First, ensure you've added ash_postgres to your mix.exs file.

{:ash_postgres, "~> x.y.z"}

To use this data layer, you need to chage your Ecto Repo's from use Ecto.Repo, to use AshPostgres.Repo. because AshPostgres adds functionality to Ecto Repos.

Then, configure each of your Ash.Resource resources by adding use Ash.Resource, data_layer: AshPostgres.DataLayer like so:

defmodule MyApp.SomeResource do
  use Ash.Resource, data_layer: AshPostgres.DataLayer

  postgres do
    repo MyApp.Repo
    table "table_name"
  end

  attributes do
    # ... Attribute definitions
  end
end
