Overview

The Radiant::Config object emulates a hash with simple bracket methods which allow you to get and set values in the configuration table:

Radiant::Config['setting.name'] = 'value'
Radiant::Config['setting.name'] #=> "value"

Currently, there is not a way to edit configuration through the admin system so it must be done manually. The console script is probably the easiest way to this:

% script/console production
Loading production environment.
>> Radiant::Config['setting.name'] = 'value'
=> "value"
>>

Radiant currently uses the following settings:

admin.title

the title of the admin system

admin.subtitle

the subtitle of the admin system

defaults.page.parts

a comma separated list of default page parts

defaults.page.status

a string representation of the default page status

defaults.page.filter

the default filter to use on new page parts

defaults.page.fields

a comma separated list of the default page fields

dev.host

the hostname where draft pages are viewable

local.timezone

the timezone name (‘rake -D time` for full list) used to correct displayed times

page.edit.published_date?

when true, shows the datetime selector for published date on the page edit screen
