Multiple associations

[Michael Moulsdale]

I'm trrying to fabricate a model that has multiple associations. because each association has different, specific, element I can't just do 2.times. Additionally because the parent model has an after_update statement I want to build it all at the same time rather than creating the associated model after the fact.

I have tried the following

    it "builds multiple associations" do
        customer_1 = Fabricate(:customer)
        customer_2 = Fabricate(:customer)
        trip_1 = Fabricate(:trip, date: Date.today) do
            participations { [Fabricate(:participation, customer_id: customer_1.id )] }
            participations { [Fabricate(:participation, customer_id: customer_1.id )] }
        end
        expect(Participation.where("trip_id =?", trip_1.id).size).to eq 2
    end

but this just builds one association, using the second line

I've tried using lines such as participations { [Fabricate(:participation, customer_id: customer_1.id )], [Fabricate(:participation, customer_id: customer_2.id )] }

but this just throws up an error. Any thoughts on how to achieve this?
