Hey Daryl,
I've dealt with a similar issue before and solved it using something like
this (disclaimer, I haven't actually tested the following code):
factory :pd_request do
association :employee, :factory => :employee_with_supervisor
description { Faker::Lorem.words.join(' ') }
start_date 7.days.from_now
trait :approved do
status 'Approved'
name 'Lorem Ipsum...'
association :approving_manager, :factory => :employee # I'm assuming
this can be a new employee
after(:build) do |pd_request|
pd_request.approving_supervisor = pd_request.employee.supervisor
end
end
end
You'd create an approved pd_request with FactoryGirl.create(:pd_request,
:approved)
I'm a fan of using traits instead of nested Factories and have found after
:create and after :build callbacks really useful for setting up
associations that need to know about existing objects.
I hope the code above works, or at least helps you get closer to a solution.
Cheers,
Shevaun
