             Summary: Clear TASK/DAG is clearing all executions
                 Key: AIRFLOW-2558
                 URL: https://issues.apache.org/jira/browse/AIRFLOW-2558
             Project: Apache Airflow
          Issue Type: Bug
    Affects Versions: Airflow 2.0
            Reporter: Marcos Bernardelli
            Assignee: Tao Feng


When I try to clear a DAG/TASK specific execution, the Airflow try to execute all the past executions:

This behavior was changed here: [https://github.com/apache/incubator-airflow/pull/3444]

The old version looks like this:
{code:python}
drs = session.query(DagModel).filter_by(dag_id=self.dag_id).all()
{code}

Then it's changed to:
{code:python}
drs = session.query(DagRun).filter_by(dag_id=self.dag_id).all()
{code}

This new query (using DagRun) get all the past executions, even when the "Past" button is not checked.
