Factory Girl: How to set up a has_many/through association

Question

I\'ve been struggling with setting up a has_many/through relationship using Factory Girl.

I have the following models:

class Job < Ac         


        

Answer 1

This worked for me

FactoryGirl.define do
  factory :job do

    # ... Do whatever with the job attributes here

    factory :job_with_detail do

      # In later (as of this writing, unreleased) versions of FactoryGirl
      # you will need to use `transitive` instead of `ignore` here
      ignore do
        detail { create :detail }
      end

      after :create do |job, evaluator|
        job.details << evaluator.detail
        job.save
        job_detail = job.job_details.where(detail:evaluator.detail).first

        # ... do anything with the JobDetail here

        job_detail.save
      end
    end
  end
end

Then later

# A Detail object is created automatically and associated with the new Job.
FactoryGirl.create :job_with_detail

# To supply a detail object to be associated with the new Job.
FactoryGirl.create :job_with_detail detail:@detail
