-------------------------------------
Summary: Support getting variable by string in templates
Key: AIRFLOW-1076
URL: https://issues.apache.org/jira/browse/AIRFLOW-1076
Project: Apache Airflow
Issue Type: Improvement
Reporter: Daniel Huang
Assignee: Daniel Huang
Priority: Minor
Currently, one can fetch variables in templates with `{{ var.value.foo}}`. But
that doesn't work if the variable key has a character you can't use as an
attribute, like ":" or "-".
Should provide alternative method of `{{ var.value.get('foo:bar') }}`. Can then
also supply a default value if the variable is not found.
