Before starting with the ORM, it is highly recommended to familiar one's self with package:angel_serialize
, as it is the foundation for package:angel_orm
:

To enable the ORM for a given model, simply add the @orm
annotation to its definition:
The generator will produce a TodoQuery
class, which contains fields corresponding to each field declared in _Todo
. Each of TodoQuery
's fields is a subclass of SqlExpressionBuilder
, corresponding to the given type. For example, TodoQuery
would look something like:
Thus, you can query the database using plain-old-Dart-objects (PODO's):
The glue holding everything together is the QueryExecutor
interface. To support the ORM for any arbitrary database, simply extend the class and implement its abstract methods.
Consumers of a QueryExecutor
typically inject it into the app's dependency injection container:
At the time of this writing, there is only support for PostgreSQL, though more databases may be added eventually.
