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.
