Factory Girl: Creating associated records

factory-bot, ruby-on-rails

Solution

you should use `after :build` and `build_list` and assign the list to the user's association, like so:

after(:build) do |user, evaluator|
  user.stories << build_list(:story, evaluator.stories_count, user: user)
end

Problem

I'm trying to do something I think should be fairly simple with Factory Girl and can't quite get it. A user has many stories and I'm testing viewing a user's profile page, which lists their created stories. I looked up creating associated factories and the docs say I can do something like this: ``` FactoryGirl.define do factory :story do title "My Story" segments_limit 5 beginning "Once upon a time" completion_status false user end factory :user do sequence(:username) { |n| "user-#{n}" } sequence(:email) { |n| "user-#{n}@example.com" } password "password" password_confirmation "password" factory :user_with_stories do ignore do stories_count 5 end after(:create) do |user, evaluator| create_list(:story, evaluator.stories_count, user: user) end end end end ``` This doesn't seem to work though - when I get into the console and run `FactoryGirl.create(:user_with_stories).stories.length`, I get an empty array. Am I missing something?
