## class `OnAddArtifactAlias`
A new alias is assigned to an artifact.
Examples:
Define an event that triggers whenever the alias "prod" is assigned to
any artifact in the collection "my-collection":
```python theme={null}
from wandb import Api
from wandb.automations import OnAddArtifactAlias, ArtifactEvent
api = Api()
collection = api.artifact_collection(name="my-collection", type_name="model")
event = OnAddArtifactAlias(
scope=collection,
filter=ArtifactEvent.alias.eq("prod"),
)
```
### method `OnAddArtifactAlias.__init__`
```python theme={null}
__init__(
event_type: 'Literal[ADD_ARTIFACT_ALIAS]' = ADD_ARTIFACT_ALIAS,
scope: '_ArtifactSequenceScope | _ArtifactPortfolioScope | ProjectScope',
filter: 'And | Or | Nor | Not | Lt | Gt | Lte | Gte | Eq | Ne | In | NotIn | Exists | Regex | Contains | FilterExpr | dict[str, Any]' = And(())
) → None
```
**Args:**
* `event_type` (Literal\[ADD\_ARTIFACT\_ALIAS]):
* `scope` (Union\[\_ArtifactSequenceScope, \_ArtifactPortfolioScope, ProjectScope]): The scope of the event.
* `filter` (Union\[And, Or, Nor, Not, Lt, Gt, Lte, Gte, Eq, Ne, In, NotIn, Exists, Regex, Contains, FilterExpr, Dict\[str, Any]]): Additional conditions(s), if any, that are required for this event to trigger.
**Returns:**
An `OnAddArtifactAlias` object.
