[ckan-dev] Maintenance mode

Thu Apr 7 14:00:12 UTC 2016

Florian,

I believe that refers to a bit of middleware:
https://pypi.python.org/pypi/apachemiddleware/0.1.1
The source repo is long gone, but you could install it and read the
source - it's very short. I think it just returns friendly 503 error
if you try to do a POST request, which will ensure that no writes
occur, because the edit forms being submitted and writes to the API.
However you will still need to add a banner, or pop-up message when
someone tries to log-in, explaining what's going on. This would be far
better than the whole site being down.

I think this would be a great contribution to ckan core, but I'd want
to confer - it might be solved better on other sites. I'd like to know
what Django, Drupal etc do about this - no doubt there is something we
can learn.
