我编写了一个简单的规范，用无效属性测试更新操作。我希望obj属性保持不变，但由于某些奇怪的原因，测试失败，尽管属性仍然相同。
感谢您的建议。

似乎created_at和updated_at比较中存在一些错误。我不明白为什么会有不同的价值观。
我从DB中选择相同的资源......
我也试过
expect(not_updated_patient).to have_attributes(patient.attributes)
但它也失败了。
我的发展环境：
答案 0 :(得分：0)
它们与您应该选择要比较的抵消属性不同。 updated_at和created_at不同。
也许？
expect(not_updated_patient.attributes.without('updated_at', 'created_at')).to eq(patient.attributes.without('updated_at', 'created_at'))
