Scoping Resources using specialized subclasses
----------------------------------------------
You can use specialized subclasses of ``Resource`` provider to initialize and shutdown resources by type.
Allowing for example to only initialize a subgroup of resources.
.. code-block:: python
class ScopedResource(resources.Resource):
pass
def init_service(name) -> Service:
print(f"Init {name}")
yield Service()
print(f"Shutdown {name}")
class Container(containers.DeclarativeContainer):
scoped = ScopedResource(
init_service,
"scoped",
)
generic = providers.Resource(
init_service,
"generic",
)
To initialize resources by type you can use ``init_resources(resource_type)`` and ``shutdown_resources(resource_type)``
methods adding the resource type as an argument:
.. code-block:: python
def main():
container = Container()
container.init_resources(ScopedResource)
# Generates:
# >>> Init scoped
container.shutdown_resources(ScopedResource)
# Generates:
# >>> Shutdown scoped
And to initialize all resources you can use ``init_resources()`` and ``shutdown_resources()`` without arguments:
.. code-block:: python
def main():
container = Container()
container.init_resources()
# Generates:
# >>> Init scoped
# >>> Init generic
container.shutdown_resources()
# Generates:
# >>> Shutdown scoped
# >>> Shutdown generic
It works using the :ref:`traverse` method to find all resources of the specified type, selecting all resources
which are instances of the specified type.
