--------------------------------------
Summary: 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
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.
