I have a User model that is only valid when there is at least one Address:

class User
 has_many :addresses
 validates :addresses, length: miniumum: 1
end

class Address
 belongs_to :user
end

I tried defining my FactoryBot factory like this:

FactoryBot.define do
 factory :user do
 association :address
 name 'test'
 end
end

When creating a user with create(:user), there's an error that user could not be saved due to missing address. It seems the association is only created after the user is created (which obviously creates a validation error). What's the correct way to build my factory?

Thanks

  How does it work in real life? I mean - how can I set a user_id for an address without creating a user?

  By saving the user and a minimum of 1 address through a nested form, in which user accepts nested attributes for the address. This part is already working, just wanted to write tests for this.

Try with:

FactoryBot.define do
 factory :user do
 name 'test'

 before(:create) do |user|
 user.addresses << build(:address, user: user)
 end
 end
end

Please remember to create a factory for address as well.

association attribute, should only be used if the model contains the foreign key (the model which you declared belongs_to on it). Remove association :address from your factory and use before(:create) callback to build addresses before saving user:

FactoryBot.define do
 factory :user do
 name 'test'
 before(:create) object.addresses.build() 
 end
end
