------------------------------------

             Summary: Show Graph/Tree view and Task Instance logs using 
executed DagRun, not current
                 Key: AIRFLOW-574
                 URL: https://issues.apache.org/jira/browse/AIRFLOW-574
             Project: Apache Airflow
          Issue Type: Improvement
    Affects Versions: Airflow 1.7.1.3
            Reporter: Boris Tyukin


Airflow currently is using the current Dag to show Tree and Graph views. This 
is an issue when DAG tasks are generated dynamically using some external 
metadata or list of files in a target folder or list of database tables - tasks 
that were generated for previous runs are not displayed. Also new tasked are 
shown only after Airflow webserver restart. 

IMHO this is an important issue as one of the huge benefits of Airflow is 
generating tasks and workflows programmatically. Tasks should be shown properly 
on a web interface for monitoring / troubleshooting purposes.
