FactoryGirl set attribute with association

I have a Note object attached to a Course, I want to randomly set the @note.number to rand(@note.course.sections) in FactoryGirl. I tried:

  factory :note do
    association :course
    number { ranb(course.sections) }
    content { Faker::Lorem.paragraphs(paragraph_count = 1).join(" ") }
  end

It doesn't work and says the course is nil. What's the right way to do this? Thanks!

I don't understand the relationship between Course#sections and Note#number, also I can only assume you've defined the Course factory. I've tested the following, and it works fine:

FactoryGirl.define do
  factory :course do
    sequence(:sections)
  end

  factory :note do
    course
    number { rand(course.sections) }
  end
end


note = FactoryGirl.create(:note)
# => <Note id: 11, course_id: 12, number: 6, ...>
note.course
# => <Course id: 12, sections: 9, ...>
