Source-generated ORM for use with the Angel framework. Documentation is coming soon.
|
|
|
|
This ORM can work with virtually any database, thanks to the functionality exposed by
|
|
|
|
`package:query_builder`.
|
|
|
|
|
|
|
|
```dart
|
|
|
|
library angel_orm.test.models.car;
|
|
|
|
|
|
|
|
import 'package:angel_framework/common.dart';
|
|
|
|
import 'package:angel_orm/angel_orm.dart' as orm;
|
|
|
|
import 'package:angel_serialize/angel_serialize.dart';
|
|
|
|
import 'car.postgres.g.dart';
|
|
|
|
part 'car.g.dart';
|
|
|
|
|
|
|
|
@serializable
|
|
|
|
@orm.model
|
|
|
|
class _Car extends Model {
|
|
|
|
@override
|
|
|
|
String id;
|
|
|
|
|
|
|
|
String manufacturer;
|
|
|
|
|
|
|
|
int year;
|
|
|
|
|
|
|
|
@override
|
|
|
|
@Alias('created_at')
|
|
|
|
DateTime createdAt;
|
|
|
|
|
|
|
|
@override
|
|
|
|
@Alias('updated_at')
|
|
|
|
DateTime updatedAt;
|
|
|
|
}
|
|
|
|
```
|
|
|
|
|
|
|
|
After building, you'll have access to a `Repository` class with strongly-typed methods that
|
|
|
|
allow to run asynchronous queries without a headache.
|
|
|
|
You can run complex queries like:
|
|
|
|
|
|
|
|
```dart
|
|
|
|
import 'package:angel_framework/angel_framework.dart';
|
|
|
|
import 'package:postgres/postgres.dart';
|
|
|
|
import 'car.dart';
|
|
|
|
import 'car.orm.g.dart';
|
|
|
|
|
|
|
|
/// Returns an Angel plug-in that connects to a PostgreSQL database, and sets up a controller connected to it...
|

|
|
|
AngelConfigurer connectToCarsTable(PostgreSQLConnection connection) {
|
2017-06-17 16:45:31 +00:00
|
|
|
return (Angel app) async {
|
|
|
|
// Instantiate a Car repository, which is auto-generated. This class helps us build fluent queries easily.
|
|
|
|
var cars = new CarRepository(connection);
|
|
|
|
|
|
|
|
// Register it with Angel's dependency injection system.
|
|
|
|
//
|
|
|
|
// This means that we can use it as a parameter in routes and controllers.
|
|
|
|
app.container.singleton(cars);
|
|
|
|
|
|
|
|
// Attach the controller we create below
|
|
|
|
await app.configure(new CarService(cars));
|
|
|
|
};
|
|
|
|
}
|
|
|
|
|
|
|
|
@Expose('/cars')
|
|
|
|
class CarService extends Controller {
|
|
|
|
/// `manufacturerId` and `CarRepository` in this case would be dependency-injected. :)
|
|
|
|
@Expose('/:manufacturerId/years')
|
|
|
|
getAllYearsForManufacturer(String manufacturerId, CarRepository cars) {
|
|
|
|
return
|
|
|
|
cars
|
|
|
|
.whereManufacturer(manufacturerId)
|
|
|
|
.get()
|
|
|
|
.map((Car car) {
|
|
|
|
// Cars are deserialized automatically, woohoo!
|
|
|
|
return car.year;
|
|
|
|
})
|
|
|
|
.toList();
|
|
|
|
}
|
|
|
|
}
|
|
|
|
```
