Javascript 未能上载绘画：文章必须存在-opoloo

有人在使用Opolo lines引擎进行rails博客框架吗

如果您有，您是否遇到此错误消息未能上载绘画：在尝试将图片上载到您的博客帖子时，文章必须存在？否则，有人可以在服务器日志中解释下面的错误消息，因为我真的不知道如何读取它

干杯

下面的行0.1ms开始事务，0.1ms回滚事务告诉您一些验证失败。谢谢，@Y先生，有没有办法检查哪个验证失败了？@ttinggggg您可以在以下行中添加一个调试器：：Admin：：PicturesControllercreate并查看picture object@picture\u变量上是否有任何错误。错误使用感谢@Deepak Mahakale，我该怎么做？您是否使用了这些gem？byebug、pry、debugger
