[jira] [Created] (AIRFLOW-1076) Support getting variable by string in templates

Daniel Huang created AIRFLOW-1076:
-------------------------------------

             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.
