I made a bunch of mistakes trying to make this work until I looked at the
non-taskflow example.
This should work for taskflow:
```python
from datetime import datetime, timedelta
from airflow.decorators import dag
from airflow.decorators import task
def get_run_date():
return '01-01-2021'
default_args = {
'owner': 'airflow',
'depends_on_past': False,
'email_on_failure': False,
'email_on_retry': False,
'retries': 1,
'retry_delay': timedelta(minutes=5)
}
@dag(default_args=default_args,
schedule_interval=None,
start_date=datetime(2021, 8, 1),
dagrun_timeout=timedelta(hours=4),
max_active_runs=1)
def xcomm_taskflow_dag():
@task()
def set_date():
date ="1-2-21"
return date
@task()
def xcomm_task2(**kwargs):
date=kwargs['ti'].xcom_pull(task_ids="set_date")
print(f"xcomm_task2:{date}")
@task()
def xcomm_task3(**kwargs):
date=kwargs['ti'].xcom_pull(task_ids="set_date")
print(f"xcomm_task3:{date}")
set_date() >> xcomm_task2() >> xcomm_task3()
xcomm_taskflow_dag=xcomm_taskflow_dag()
```
