Subject [jira] [Created] (AIRFLOW-1521) Template fields definition for bigquery_table_delete_operator doesn't work
Date Fri, 18 Aug 2017 18:08:00 GMT

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

             Summary: Template fields definition for bigquery_table_delete_operator doesn't
work
                 Key: AIRFLOW-1521
                 URL: https://issues.apache.org/jira/browse/AIRFLOW-1521
             Project: Apache Airflow
          Issue Type: Bug
          Components: contrib
    Affects Versions: Airflow 1.8
            Reporter: Moe Nadal
             Fix For: 1.8.2


I obtain the following error when trying to use the `biaquer_table_delete_operator` with the
recent fix to add the field `deletion_dataset_table` in the list of template fields : 

`[2017-08-18 10:58:30,556] {models.py:1426} ERROR - 'BigQueryTableDeleteOperator' object has
no attribute 'd'
Traceback (most recent call last):
  File "/usr/lib/python2.7/site-packages/airflow/models.py", line 1368, in run
    self.render_templates()
  File "/usr/lib/python2.7/site-packages/airflow/models.py", line 1587, in render_templates
    content = getattr(task, attr)
AttributeError: 'BigQueryTableDeleteOperator' object has no attribute 'd'`

This is caused by python behavior which interpret a list with only one string as a list of
characters : 
`template_fields = ('deletion_dataset_table')`

I'm preparing a PR to change it to : 
`template_fields = ('deletion_dataset_table',)`
