Radiant_user_attributes_extension is a project mainly written in Ruby, it's free.
Store settings at the user level in a Radiant project
= User Attributes
Radiant has a config system to configure an entire site. These settings live in config/environment.rb
This extension lets you set configure options on a user.
Extension developers can avoid creating a migration that adds new fields to User.
This especially applies to when you have to write a custom Dashboard, for example with Saturn Flyer's Dashboard extension (https://github.com/saturnflyer/radiant-dashboard-extension)
This extension adds a field to user named user_attributes. It's a Rails serialized_field (meaning that it will serialize whatever you give it into YAML).
Each save this extension checks, and if this attribute is nil, it will save an empty hash in the record.
So, to add a "blog location" attribute:
u = User.find ...
u.user_attributes["blog_location"] = "ryans_blog" u.save!
