Using factory girl to create HABTM association

Question

I've been trying now for hours to get factorygirl to create two factories - one for users, one for organizations. But I don't seem to understand how I can reflect a 'has_and_belongs_to_many' relationship in factories, as soon as I try to create an organization and associate it with an admin user, I run into various error messages (depending on the approach I use). My model seems to be working fine, my seed file populates the dev DB and all the associations are created. Right now my files look like this: user factory ``` FactoryGirl.define do factory :user do email 'example@example.com' password 'password' password_confirmation 'password' after(:create) {|user| user.add_role(:user)} factory :owner do after(:create) {|user| user.add_role(:owner)} end factory :admin do after(:create) {|user| user.add_role(:admin)} end factory :superadmin do after(:create) {|user| user.add_role(:superadmin)} end end end ``` Organization factory ``` FactoryGirl.define do factory :organization do |f| f.name…

Accepted Answer

Looks like you are not assigning `users` correctly and not creating the `:admin` user properly. For this to work, you need to assign an array of users to `organization.users`. And, you need to populate that array with a `User` instance (this assumes you have a `User` factory named `:admin`).

```
factory :organization do
  name "example"
  website "www.aquarterit.com"
  after(:create) {|organization| organization.users = [create(:admin)]}
end
```
