我不确定您是否还需要我发布其他内容。它无效，因为您的模型对象未通过验证。在您的
before@micropostputs @micropost.errors.messages
将出现失败的验证（字段和错误消息）散列。修复这些，然后您的对象将是有效的。一些早期的评论者对从何处着手帮助解决问题提出了建议。这消除了错误 micropost\u规范rb

你可以输入micropost的值并检查它的值吗？我如何输入micropost的值并检查它的值？在一些测试用例中使用puts语句，然后运行bundle exec rspec spec，它会像…………micropost:blah.F……一样打印你的micropost，谢谢你的帮助，但我是rails新手。我不知道要添加puts语句的文件。我应该向文件中添加什么。谷歌搜索“puts语句”没有帮助。你在
之前的一系列块都在覆盖@micropost
，因此它们基本上是在相互撤销。这是我要做的第一件事。你的工厂里有相同的数据，所以你应该使用它。我这样做了，它通过了<代码>在{@micropost=user.micropost.build之前（内容：“Lorem ipsum”，标题：“这是一个测试标题”，隐私：“1”，组：“这是一个测试组”，loc1T:“安大略省多伦多市邦德街21号”，loc1Lat:“43.654653”，loc1Lon:-79.377627，loc2T:“安大略省多伦多市邦德街21号”，loc2Lat:“43.654653”，loc2Lon:“-79.377627”，开始时间：“2000年1月1日12:01:01”，结束时间：“2000年1月2日12:01:01”，图像URL:”http://i.cdn.turner.com/cnn/.e/img/3.0/global/header/hdr-main.gif）放置@micropost.errors.messages}
@livi1717检查test.log。日志中可能有更多关于对象无效原因的线索。
