I have installed the latest version of rails and jruby. I have copied
all my files from rails 2.3.5 version and am trying to bring all to work
in this version
Project.rb
------------------
class Project < ActiveRecord::Base
has_and_belongs_to_many :people
has_many :documents, :conditions => ["project_id =?", self.id ]
..
..
end
application_helper.rb
--------------------------
def find_projects
user = Person.find(session[:userid])
projects = Project.find(:all)
..
..
..
end
I am getting an error
undefined method `id'' for #<Class:0x182237ac> (self.id is the
problem
guess)

I suggest opening your console - type Person - the console should return to_s of the class - if not, the person model isn''t in your path better yet, take this opportunity to write some tests - start with the Person model On 2012-07-31, at 2:38 PM, masta Blasta wrote:> deal bitte wrote in post #1070764: >> >> Project.rb >> ------------------ >> class Project < ActiveRecord::Base >> has_and_belongs_to_many :people >> has_many :documents, :conditions => ["project_id =?", self.id ] >> .. >> .. >> end >> >> application_helper.rb >> -------------------------- >> >> def find_projects >> user = Person.find(session[:userid]) >> projects = Project.find(:all) >> .. >> .. >> .. >> end >> >> I am getting an error >> undefined method `id'' for #<Class:0x182237ac> (self.id is the problem >> guess) > > 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.

Hello, Your class Project does not have a method by the name ''id''.
