--------------------------------------
Summary: (www_rbac) Flask flash messages not categoried (result in
'incomplete' UI display)
Key: AIRFLOW-3067
URL: https://issues.apache.org/jira/browse/AIRFLOW-3067
Project: Apache Airflow
Issue Type: Improvement
Components: webapp
Affects Versions: 1.10.0
Reporter: Xiaodong DENG
Assignee: Xiaodong DENG
The Flask flash messages are not categorized properly (ref:
[http://flask.pocoo.org/docs/1.0/patterns/flashing/#flashing-with-categories).]
This makes the the flash messages in the _*www_rbac*_ UI come with no
background color (please check the screenshots attached. We don't see this
issue in _*www*_ UI as all flash messages without categories are classed into
'info').
Solution:
* Add proper category when we invoke *flash()*.
* We can't use category 'error'. Flask AppBuild would assign class
`alert-[category]` to that message when dispalying it (ref:
https://github.com/dpgaspar/Flask-AppBuilder/blob/master/flask_appbuilder/templates/appbuilder/flash.html
). In bootstrap-theme.css, we don't have `alert-error` (we have `alert-danger`
instead).
