Title Body

In a Rails application, given three models User, Article and Reviewer with the following relationships and validations: class User < ActiveRecord::Base has_many :articles has_many :reviewers end class Reviewer < ActiveRecord::Base belongs_to :user belongs_to :article end class Article < ActiveRecord::Base belongs_to :user has_many :reviewers validate :has_reviewers? def has_reviewers? errors.add(:base, "article must have at least one reviewer.") if self.reviewers.blank? end end And the following factories using the newer DSL: FactoryGirl.define do factory :user do name { (8...20).map{ ('a'..'z').to_a[rand(26)] }.join } age { Kernel.rand(100) } end factory :article do body "This is the article content" title "This is the title" user after_create do |article| article.reviewers = create_list(:user, 2) end end factory :reviewer do user article state { ["published","draft","rejected","archived"][Kernel.rand(4)] } end end The factory to create the article doesn't work because the validation fails before the reviewers are created: > FactoryGirl.create(:article) ActiveRecord::RecordInvalid: Validation failed: article must have at least one reviewer. I have made more attempts than I would like to admit trying to overcome this hurdle, but I am stuck! One idea I had was to create the reviewers like this: factory :article do body "This is the article content" title "This is the title" user reviewers {|a| [FactoryGirl.create(:reviewer, article: a)] } end but in this context, the "a" is not the instance. So that doesn't work either, like it used to.
