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, "~> 1.0"}
|
|
```
|
|
|
|
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
|
|
```
|
|
|
|
