Ash Berlin-Taylor resolved AIRFLOW-618.
---------------------------------------
Resolution: Done
> Fix failing refresh_from_db() query (affects unit tests)
> --------------------------------------------------------
>
> Key: AIRFLOW-618
> URL: https://issues.apache.org/jira/browse/AIRFLOW-618
> Project: Apache Airflow
> Issue Type: Bug
> Reporter: Jeremiah Lowin
> Priority: Major
>
> Travis runs are failing with sqllite. Commonly, the error is traced to:
> File "/home/travis/build/apache/incubator-airflow/airflow/models.py", line
> 3657, in refresh_from_db
> ).one()
> File
> "/home/travis/build/apache/incubator-airflow/.tox/py34-cdh-airflow_backend_sqlite/lib/python3.4/site-packages/sqlalchemy/orm/query.py",
> line 2760, in one
> raise orm_exc.NoResultFound("No row was found for one()")
> nose.proxy.NoResultFound: No row was found for one()
> In other words, the database is finding no rows that match the query filter.
> Manually inspecting the database, I can see that the filter SHOULD succeed.
> It appears that manually casting the DateTime parameters as SQL DateTimes
> fixes the issue in this instance.
