Question

当我运行bundle exec rake test时，尝试插入行时出现外键错误：

UserPreferencesControllerTest#test_should_create_user_preference:
ActiveRecord::InvalidForeignKey: PG::ForeignKeyViolation: ERROR:  insert or update on table "user_preferences" violates foreign key constraint "fk_rails_d9451c7b48"
DETAIL:  Key (sport_id)=(1) is not present in table "sports".
: INSERT INTO "user_preferences" ("skill_level", "notes", "user_id", "sport_id", "created_at", "updated_at") VALUES ($1, $2, $3, $4, $5, $6) RETURNING "id"
    app/controllers/user_preferences_controller.rb:30:in `block in create'
    app/controllers/user_preferences_controller.rb:29:in `create'
    test/controllers/user_preferences_controller_test.rb:26:in `block (2 levels) in <class:UserPreferencesControllerTest>'
    test/controllers/user_preferences_controller_test.rb:25:in `block in <class:UserPreferencesControllerTest>'

看起来没有'体育'装置的id为1。

但是，灯具存在于test / fixtures / sports.yml中，如下所示：

--- {}

basketball:
  id: '1'
  name: "basketball"
  description: "game with a large bouncy ball"

发生了什么事？

Answer 1

sports.yml的第一行声明运动装置为空集：{}。将第一行替换为---而不是--- {}

Rails单元测试没有加载灯具
