Subject [jira] [Updated] (AIRFLOW-2415) Airflow Operators are unable to support integers in templatized fields
Date Thu, 03 May 2018 21:01:00 GMT

     [ https://issues.apache.org/jira/browse/AIRFLOW-2415?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Max Payton updated AIRFLOW-2415:
--------------------------------
    Description: 
Currently, if you have an operator with a template fields argument that is a dictionary, e.g.:
{code:java}
template_fields = ([dict_args])
{code}
And you populate that dictionary with a field that an integer in a DAG, e.g.:
{code:java}
Operator(
    ...
    dict_args = {'ds': '{{ ds }}', num_times: 5},
    ...
){code}
Then airflow will give you the following error:
{code:java}
{base_task_runner.py:95}
INFO - Subtask: airflow.exceptions.AirflowException: Type '<type 'int'>' used for parameter
'dict_args[num_times]' is not supported for templating
{code}
