Component

class asphalt.mongodb.MongoDBComponent(*, client_args=None, resource_name='default')

Bases: Component

Creates an AsyncIOMotorClient resource.

The client will not connect to the target database until it’s used for the first time.

Parameters:

• client_args – a dictionary of keyword arguments to pass to AsyncIOMotorClient

• resource_name – default values for omitted AsyncIOMotorClient arguments

async start(ctx)

Perform any necessary tasks to start the services provided by this component.

In this method, components typically use the context to:

• add resources and/or resource factories to it (add_resource() and add_resource_factory())

• request resources from it asynchronously (request_resource())

It is advisable for Components to first add all the resources they can to the context before requesting any from it. This will speed up the dependency resolution and prevent deadlocks.

Parameters:

ctx – the containing context for this component
