In the application I’m currently developing a User has_many Jobs, and each Job has a bunch of nested resources. The application calls for a Dashboard, filled with the latest changes to any Job the currently logged-in user is assigned to.
Sounds difficult huh?
def self.get_latest_items_for(current_user)
assigned_job_ids = current_user.jobs.collect(&:id)
find(:all, :conditions => ["job_id in (?)", assigned_job_ids])
end
In order to get the currently logged-in user’s list I just do:
RecentItem.get_latest_items_for(current_user)
Simple, elegant, understandable, and concise.
