Installation
def deps do
[
{:ash_uuid, "~> 1.1.2"},
]
end
Adoption
Adoption:
add
{:ash_uuid, "~> 1.1.2"}
to yourmix.exs
project deps;add
AshUUID.PostgresExtension
to your app Repo's installed_extensions and set AshUUID configmigration_default?: true
if Postgres-side UUIDs generation is needed;use the extension in your resources
use Ash.Resource, data_layer: AshPostgres.DataLayer, extensions: [AshUUID]
;simply use that for your fields
uuid_attribute :id
.
Configuration
lib/myapp/repo.ex
:
Using the PostgresExtension allows postgres-side uuid-v7 generation.
# App: Postgres migration defaults, not required
`
defmodule Myapp.Repo do
use AshPostgres.Repo, otp_app: :myapp
@impl AshPostgres.Repo
def installed_extensions do
["ash-functions", "uuid-ossp", "citext", AshUUID.PostgresExtension]
end
end
config/config.exs
:
# AshUUID: Your otp_app name, required!
config :ash_uuid, :otp_app, :myapp
# Myapp: Customized defaults, not required
config :myapp, :ash_uuid,
version: 7, # default
encoded?: true, # default
prefixed?: true, # default
migration_default?: true, # default to false
strict?: true # default to true
# Ash: Type shorthands, not required
config :ash, :custom_types, uuid: AshUUID.UUID
# Ash: Default belongs_to type, not required
config :ash, :default_belongs_to_type, AshUUID.UUID
Usage
defmodule Pineapple do
use Ash.Resource, data_layer: AshPostgres.DataLayer, extensions: [AshUUID]
code_interface do
define_for Area
end
postgres do
table "pineapples"
repo MyApp.Repo
end
attributes do
uuid_attribute :id, prefix: "pnp"
create_timestamp :inserted_at
end
actions do
defaults [:create, :read, :update]
end
end

Roadmap
-
Developing
To get set up with the development environment, you will need a Postgres
instance and an environment variable DATABASE_URL according to config/config.exs
.
You may now generate and apply the test migrations:
mix ash_postgres.generate_migrations
mix ash_postgres.create
mix ash_postgres.migrate
mix test
AshUUID uses ex_check
to bundle the test configuration, and simply running
mix check
should closely follow the configuration used in CI.
