Question

怎么可能？在订单模型：

validates :pay_type_id, inclusion: PayType.ids

在测试中：

patch :update, id: @order, order: { address: @order.address, email: @order.email, name: @order.name, pay_type_id: PayType.ids.first }
assert_equal [], PayType.ids

测试结果：

1) Error:
OrdersControllerTest#test_should_create_order:
ActiveRecord::RecordInvalid: Validation failed: Pay type is not included in the list
    app/controllers/orders_controller.rb:41:in `block in create'
    app/controllers/orders_controller.rb:40:in `create'
    test/controllers/orders_controller_test.rb:36:in `block (2 levels) in <class:OrdersControllerTest>'
    test/controllers/orders_controller_test.rb:35:in `block in <class:OrdersControllerTest>' 

2) Failure:
OrdersControllerTest#test_should_deny_update_if_not_logged_in [/home/eugenes/Dropbox/work/depot/test/controllers/orders_controller_test.rb:85]:
Expected: []
  Actual: [298486374, 980190962]

在开发环境中一切都好。我做错了什么？

您可以执行类似

的操作

validates_inclusion_of :pay_type_id, :in => lambda { |_| PayType.pluck(:id) }

至少这样，每次验证器运行时，您都会对数据库进行新的查询并获取最新的PayType ID。

PS。由于存在错误而包含虚拟参数_ - 对于后续操作，请查看https://github.com/rails/rails/issues/13689。

验证失败：<something>未包含在列表中（仅在测试中）
