例如,我有两个模型,一个用户和一个帖子。帖子属于用户,用户有很多帖子
#spec/factories/post.rb
FactoryBot.define do
factory :post do
user
body Faker::Movie.quote
posted_at "2018-04-03 13:33:05"
end
end
#spec/factories/user.rb
FactoryBot.define do
factory :user do
first_name 'Jake'
end
end
在测试中使用Rspec我想这样做:
user = create(:user, first_name: 'Barry') #id 1
post = create(:post, user: user)
我希望post的user_id为1但是它之前创建了另一个用户而user_id是2.
如何使用factory_bot / factory_girl创建对象时指定关联?
答案 0 :(得分:12)
您应该使用explicit
个关联,而不是implicit
个关联:
#spec/factories/post.rb
FactoryBot.define do
factory :post do
association :user # <<<--- here the change
body Faker::Movie.quote
posted_at "2018-04-03 13:33:05"
end
end
#spec/factories/user.rb
FactoryBot.define do
factory :user do
first_name 'Jake'
end
end

另一个选择是在父级中使用#trait
方法。
FactoryBot.define do
factory :post do
user nil
body Faker::Movie.quote
posted_at "2018-04-03 13:33:05"
end
end
FactoryBot.define do
factory :user do
first_name 'Jake'
end
trait :with_post do
after(:create) do |user|
create(:post, user_id: user.id)
end
end
end
FactoryBot.create(:user, :with_post)
