Not really answering your question here, but i would restructure some of
this code as follows, to better go with rails 3
class Project < ActiveRecord::Base
has_many :people, :through => 'people_project_join_table'
has_many :documents #:foreign_key => 'project_id' is default for this
relationship. Don't need.
..
..
def find_projects
user = Person.find(session[:userid])
projects = Project.all
..
..
..
end

Beyond that, whenever you get an error like 'undefined method for
class', first make sure you're in fact working with the class you think
you're working with by doing myobj.class
a common slip-up for me is trying to use object methods on an array of
said objects. Most scopes and associations will return arrays.
