PowerBIDataset#

class langchain_community.utilities.powerbi.PowerBIDataset[source]#

Bases: BaseModel

Create PowerBI engine from dataset ID and credential or token.

Use either the credential or a supplied token to authenticate. If both are supplied the credential is used to generate a token. The impersonated_user_name is the UPN of a user to be impersonated. If the model is not RLS enabled, this will be ignored.

Create a new model by parsing and validating input data from keyword arguments.

Raises [ValidationError][pydantic_core.ValidationError] if the input data cannot be validated to form a valid model.

self is explicitly positional-only to allow self as a field name.
