:through difficulties

I'm trying to use :through on a many-to-many relationship.

I've got the following three models:

  class User < ActiveRecord::Base     has_many :authors     has_many :submissions, :through => :authors

  class Author < ActiveRecord::Base     belongs_to :submission     belongs_to :user

  class Submission < ActiveRecord::Base     has_many :authors     has_many :users, :through => :authors

I've also got test data for each of the models, but when I try to run either of the following in script/console I get the subsequent error:

  user.submissions   submission.users

  NameError: undefined local variable or method

Any suggestions on how to figure out what I've done wrong?

Do you have all the correct fields on these tables to support the relationships?

Can you post an exact log of what you're typing in the console? I suspect you're just misusing the relationships somehow.
