How to set up factory in FactoryGirl with has_many association

Question

Can someone tell me if I\'m just going about the setup the wrong way?

I have the following models that have has_many.through associations:

class List

You could use trait:

FactoryGirl.define do
  factory :listing do
    ...

    trait :with_features do
      features { build_list :feature, 3 }
    end
  end
end

With callback, if you need DB creation:

...

trait :with_features do
  after(:create) do |listing|
    create_list(:feature, 3, listing: listing)
  end
end

Use in your specs like this:

let(:listing) { create(:listing, :with_features) }

This will remove duplication in your factories and be more reusable.
