[jira] [Commented] (AIRFLOW-1022) Subdag can't receive templated fields

    [ https://issues.apache.org/jira/browse/AIRFLOW-1022?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16490119#comment-16490119 ] 

Ruslan Sivak commented on AIRFLOW-1022:
---------------------------------------

This is marked as an easy fix.  Why hasn't it been done in over a year?   

I am running into this problem now as well - there is no way to pass something from a task into a subdag.

> Subdag's can't receive any templated fields as the Operator is setted as tuple() (https://github.com/apache/incubator-airflow/blob/master/airflow/operators/subdag_operator.py#L24) instead of any other templated dict like on PythonOperator (https://github.com/apache/incubator-airflow/blob/master/airflow/operators/python_operator.py#L52).
> That makes impossible on getting some important values like execution_date.
