Subject [jira] [Commented] (AIRFLOW-6195) queued_dttm is "None" on UI, and not updated when tasks requeued
Date Sun, 08 Dec 2019 18:02:00 GMT


Bjorn Olsen commented on AIRFLOW-6195:

Turns out this actually affects several fields, due to them being missing from refresh_from_db()
in the TaskInstance model file. Fix incoming

> When inspecting a task instance on the UI, the value for queued_dttm displays as 'None'
despite having a value in the DB. Also, the value for queued_dttm is from when the task was
first queued and not updated if it is requeued - it is not clear if this is intentional behaviour
or not.

> In DB:

> In reality, task was queued on 8 December and run shortly after.
> queued_dttm in the DB is from the very first attempt, and is not updated from recent
