To retrieve the asset key of an
AssetsDefinition
object, you can access the
_key
property if the
AssetsDefinition
is associated with a single asset key. If the
AssetsDefinition
has more than one asset key, you would use the
_keys
property to get all associated asset keys. These properties are part of the internal API of Dagster and are intended to be used within the system rather than by end users directly. Here's how you can access these properties according to the documentation: - For a single asset key:
assets_definition._key
- For multiple asset keys:
assets_definition._keys
Please note that these are private properties (as indicated by the underscore prefix), and their use is generally discouraged outside of the Dagster codebase itself because they might change without notice in future releases. However, they are documented, so you can use them if you understand the risks associated with relying on internal APIs. Keep in mind that the best practice for interacting with assets in Dagster is through the public APIs and the decorators provided for defining assets, such as
@asset
. If you need to work with asset keys in a user-facing part of your code, consider whether there's a way to achieve your goal using the public APIs. If you're unsure, you might want to consult the documentation or seek advice from the Dagster community for best practices.
