ruby - Factory Girl - HABTM 的可变数量的关联对象

Question

如果我有 2 个模型 - 例如。商店和品牌，我想为拥有 3 到 10 个品牌的商店建模，使用工厂女郎做这件事的好方法是什么？

factory :brand do |b|
  b.name "Hip Brand"
  b.url  { "http://#{name}.com" }
end    

factory :shop do |s|
  name        "Cool Shop"
  after_create {
    count = 0
    (5..10).to_a.sample.times do
      count += 1
      Factory(:brand, :shops => s, :name => "brand #{count}")
    end
  }
end

这显然不是这样做的方法，但应该让我了解我想要实现的目标!

Answer 1

我现在无法测试，但这应该可以:

Factory.define :brand, :class => Brand do |b|
  b.name  "Hip Brand"
  b.url   { "http://#{name}.com" }
end    

Factory.define :shop, :class => Shop do |s|
  s.name     "Cool Shop"
  s.brands   { 
    count = 0
    Array(5..10).sample.times.map do
      Factory.create(:brand, :name => "Brand #{count += 1}")
    end
  }
end

或者这个:

Factory.define :shop, :class => Shop do |s|
  s.name        "Cool Shop"
  s.brand_ids   { 
    count = 0
    Array(5..10).sample.times.map do
      Factory.create(:brand, :name => "Brand #{count += 1}")[:id]
    end
  }
end
