[ckan-dev] CKAN config - definitions

Wed May 15 12:35:44 UTC 2013

Hi,

Following on from the discussion about the ckan configuration:

We need to define config options currently we do this in app_globals

eg

'search.facets.default': {'default': '10', 'type': 'int',
                             'name': 'facets_default_number'},

This needs to be expanded for example to have a description, example etc
This starts to get messy and hard to read.

I want to add a new file like this

config_options.ini
============

[search.facets.default]
default = 10
type = int
name = facets_default_number
description =
This is some long bit of rst
so that it can be in the docs

..note::

  something important

example = config_options.ini = 10

[next.option]
....

Would this be an acceptable format for people?  This would be the only
place that the config options where defined.
