----------------------------------------

             Summary: Incorrect templating when used with .format
                 Key: AIRFLOW-436
                 URL: https://issues.apache.org/jira/browse/AIRFLOW-436
             Project: Apache Airflow
          Issue Type: Bug
            Reporter: Sumit Maheshwari


Found that when {{.format}} is used in a templatable field, it produces weird results. For example:

{code:none}
t3 = BashOperator(
    task_id='wget',
    bash_command="wget {0}/{{ ds }}".format('google.com'),
    dag=dag)
{code}


produces following result:

{code:none}
{bash_operator.py:79} INFO - Running command: wget google.com/{ ds }
{code}

But if we change {{bash_command}} to following, it works as expected:

{code:none}
bash_command="wget %s/{{ ds }}"%('google.com')
{code}

{code:none}
{bash_operator.py:79} INFO - Running command: wget google.com/2016-08-05
{code}
