AshPostgres supports all the capabilities of an Ash data layer. AshPostgres is the primary Ash data layer.
Custom Predicates:
- `AshPostgres.Predicates.Trigram`
## DSL
See the DSL documentation in `AshPostgres.DataLayer` for DSL documentation
## Usage
Add `ash_postgres` to your `mix.exs` file.
```elixir
{:ash_postgres, "~> 1.3.6"}
```
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:
```elixir
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
```
## Generating Migrations
See the documentation for `Mix.Tasks.AshPostgres.GenerateMigrations` for how to generate
migrations from your resources
