Airflow use execution date: 'datetime' is undefined

Question

I want to use the execution time in Airflow and add one day to it:

'{{(execution_date + timedelta(days=1)).strftime("%Y-%m-%d")}}'

When I execute this I get

jinja2.exceptions.UndefinedError: 'timedelta' is undefined

How can I get the execution time plus one day?

Answer 1

'{{(execution_date + macros.timedelta(days=1)).strftime("%Y-%m-%d")}}'

Use macros to pass dynamic information into task instances at runtime.

Answer 2

I found the answer here: https://diogoalexandrefranco.github.io/about-airflow-date-macros-ds-and-execution-date/

You can use:

'{{(execution_date + macros.timedelta(days=1)).strftime("%Y-%m-%d")}}'

The macros object exposes common python functions and libraries like macros.datetime and macros.timedelta
