【bug info】
When you set the result_extended config parameter to True extra task meta data is stored in the backend.
But when you call backend.get_task_meta those extra meta data values are not returned. The code is ignorant of the config parameter.
I looked at which extra meta data that is saved, and the awareness of the config parameter in backends.base._get_result_meta method and applied the same logic to the backends.mongodb._get_task_meta_for method, like this:
def _get_task_meta_for(self, task_id):
"""Get task meta-data for a task by id."""
obj = self.collection.find_one({'_id': task_id})
if obj:
if self.app.conf.find_value_for_key('extended', 'result'):
return self.meta_from_decoded({
'name': obj['name'],
'args': obj['args'],
'task_id': obj['_id'],
'queue': obj['queue'],
'kwargs': obj['kwargs'],
'status': obj['status'],
'worker': obj['worker'],
'retries': obj['retries'],
'children': obj['children'],
'date_done': obj['date_done'],
'traceback': obj['traceback'],
'result': self.decode(obj['result']),
})
return self.meta_from_decoded({
'task_id': obj['_id'],
'status': obj['status'],
'result': self.decode(obj['result']),
'date_done': obj['date_done'],
'traceback': obj['traceback'],
'children': obj['children'],
})
return {'status': states.PENDING, 'result': None}
