For parameter definition, take a look at CloudTranslateTextOperator

Using the operator¶

Basic usage of the operator:

tests/system/google/cloud/translate/example_translate.py[source]

product_set_create = CloudTranslateTextOperator(
    task_id="translate",
    values=["zażółć gęślą jaźń"],
    target_language="en",
    format_="text",
    source_language=None,
    model="base",
)

The result of translation is available as dictionary or array of dictionaries accessible via the usual XCom mechanisms of Airflow:

tests/system/google/cloud/translate/example_translate.py[source]

translation_access = BashOperator(
    task_id="access", bash_command="echo '{{ task_instance.xcom_pull(\"translate\")[0] }}'"
)

Templating¶

template_fields: Sequence[str] = (
    "values",
    "target_language",
    "format_",
    "source_language",
    "model",
    "gcp_conn_id",
    "impersonation_chain",
)
