name = Triggered DAG[source]

Link to external system.

Note: The old signature of this function was (self, operator, dttm: datetime). That is still supported at runtime but is deprecated.

Return type

str

class airflow.operators.trigger_dagrun.TriggerDagRunOperator(*, trigger_dag_id, trigger_run_id=None, conf=None, execution_date=None, reset_dag_run=False, wait_for_completion=False, poke_interval=60, allowed_states=None, failed_states=None, **kwargs)[source]

Bases: airflow.models.BaseOperator

Triggers a DAG run for a specified dag_id

Parameters

  • trigger_dag_id (str) – The dag_id to trigger (templated).

  • trigger_run_id (Optional[str]) – The run ID to use for the triggered DAG run (templated). If not provided, a run ID will be automatically generated.

  • conf (Optional[Dict]) – Configuration for the DAG run (templated).

  • execution_date (Optional[Union[str, datetime.datetime]]) – Execution date for the dag (templated).

  • reset_dag_run (bool) – Whether or not clear existing dag run if already exists. This is useful when backfill or rerun an existing dag run. When reset_dag_run=False and dag run exists, DagRunAlreadyExists will be raised. When reset_dag_run=True and dag run exists, existing dag run will be cleared to rerun.

  • wait_for_completion (bool) – Whether or not wait for dag run completion. (default: False)

  • poke_interval (int) – Poke interval to check dag run status when wait_for_completion=True. (default: 60)

  • allowed_states (Optional[List]) – List of allowed states, default is ['success'].

  • failed_states (Optional[List]) – List of failed or dis-allowed states, default is None.

execute(self, context)[source]

This is the main method to derive when creating an operator. Context is the same dictionary used as when rendering jinja templates.

Refer to get_template_context for more context.
