我是新来的rails，并且在完成Michael Hartl的Ruby on Rails教程之后，我试图扩展一些功能。我通过改变微博开始，以便收集更多数据。Rails rspec错误：“预计有效？返回true，得到错误”
当运行RSpec的测试，我想不通为什么我收到此错误：
$ bundle exec rspec spec/models/micropost_spec.rb
...............F.....
Failures:
1) Micropost
Failure/Error: it { should be_valid }
expected valid? to return true, got false

我不知道是否有其他任何你需要我张贴。
可以把你的微柱价值，并检查它的值。 –
我该如何把micropost的价值和检查它的价值？ – Livi17
在某些测试用例中使用puts语句，然后运行bundle exec rspec spec，它将打印您的微博，如.......... microspost：blah.F ...... –
