我有这两个模型
class User < ApplicationRecord
devise :database_authenticatable, :registerable,
:recoverable, :rememberable, :trackable, :validatable
has_many :posts
end
class Post < ApplicationRecord
belongs_to :user
end
这些是我的工厂
FactoryGirl.define do
factory :user do
id 1
first_name 'John'
last_name 'Doe'
sequence(:email) { |n| "tester#{n}@example.com" }
password 'secretpassword'
end
end
FactoryGirl.define do
factory :post do
user_id 1
title 'This is a title'
body 'This is a body'
published_at Time.now
end
end
当我运行以下测试时,出现以下错误:
RSpec.describe User, type: :model do
let(:user) { build(:user) }
it { expect(user).to have_many(:posts) }
end
RSpec.describe Post, type: :model do
let(:post) { build(:post) }
it { expect(post).to belong_to(:user) }
end
# Error I get:
FactoryGirl::InvalidFactoryError:
The following factories are invalid:
* post - Validation failed: User must exist (ActiveRecord::RecordInvalid)
我该如何解决这个问题?
这也是我的数据库架构
create_table "posts", force: :cascade, options: "ENGINE=InnoDB DEFAULT CHARSET=utf8" do |t|
t.integer "user_id"
t.string "title"
t.text "body", limit: 65535
t.datetime "published_at"
t.datetime "created_at", null: false
t.datetime "updated_at", null: false
t.index ["user_id"], name: "index_posts_on_user_id", using: :btree
end
create_table "users", force: :cascade, options: "ENGINE=InnoDB DEFAULT CHARSET=utf8" do |t|
# Whatever devise generates
end
最佳答案
我最终找到了解决方案。缺少的关键是关联:user
FactoryGirl.define do
factory :post do
title 'This is a title'
body 'This is a body'
published_at Time.now
association :user
end
end
关于ruby-on-rails - FactoryGirl::InvalidFactoryError:验证失败:<Class> 必须存在 (ActiveRecord::RecordInvalid),我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/45871009/
