Question

我正在尝试开箱即用，但他们在一个独特的列上失败了。其他人有这个问题吗？

rails new MyApp
rails g scaffold Person name:string:uniq note:text
rails db:migrate

编辑我的夹具：

one:
  name: ONE
  note: MyText

two:
  name: TWO
  note: MyText

people_controller_test.rb用于加载初始夹具：

class PeopleControllerTest < ActionDispatch::IntegrationTest
  setup do
    @person = people(:one)
  end

但看起来它正在加载，因为我在数据库中找到它：

sqlite> select * from people;
298486374|TWO|MyText|2018-06-06 23:21:29.686780|2018-06-06 23:21:29.686780
980190962|ONE|MyText|2018-06-06 23:21:29.686780|2018-06-06 23:21:29.686780

我收到了这个错误：

Error:
PeopleControllerTest#test_should_create_person:
ActiveRecord::RecordNotUnique: SQLite3::ConstraintException: UNIQUE constraint failed: people.name: INSERT INTO "people" ("name", "note", "created_at", "updated_at") VALUES (?, ?, ?, ?)

删除test.sqlite3文件无法修复它。（我见过人们对非uniq数据有问题）

我正在使用Rails 5.1.6和Ruby 2.4.1p111。

感谢任何帮助。

我猜测您正在使用包含以下代码的自动生成测试：

test 'create' do
  assert_difference 'People.count' do
    post people_url, params: { people: { name: people(:one).name }}
  end
end

你能看到发生了什么吗？为您的创建操作生成的测试轨使用第一个人夹具的name属性。把它改成这样的东西：

test 'create' do
  assert_difference 'People.count' do
    post people_url, params: { people: { name: 'Matz' }}
  end
end

那可能会这样做。祝你好运。
