Example of adding a "leaders" relation to Group

Create migration

• rails g model GroupLeadership user:references group:references leader_id:integer
• move model to models/content_groupers

Migrate

rake db:migrate

group.rb (containing model) changes

relates :leaders, with: :group_leaderships

• add leaders to attribute_categories hash in config/attributes/group.yml

content_groupers/group_leadership.rb

class GroupLeadership < ActiveRecord::Base belongs_to :user

belongs_to :group belongs_to :leader, class_name: Character.name end

Add attributes to whitelist in groups_controller.rb

• group_leaderships_attributes: [:id, :leader_id, :_destroy],

Add any translations for the new fields to en.yml

Hit Groups page in UI to make sure everything works! (Submit form, too)

New approach (todo soon) so users can add their own

- will also support linking to different content types!

using ContentRelationship model

• user_id
• relation_text:string # Leaders
• linking_content_type:string # Location
• linking_content_id:integer # 5
• linked_content_type:string # Character
• linked_content_id:integer # 42
