Rails的Heroku模板错误 [英] Rails Template Error with Heroku

问题描述

当我部署到heroku时，当我尝试创建一个嵌套在蓝图中的新评论时，我会抛出错误。我已经尝试了很多，我甚至都不记得把它写在这里。让我知道，如果我失去了明显的东西。感谢！

When I deploy to heroku, when I try to create a new comment, which is nested in blueprints, I throw and error. I have tried so much that I can't even remember it all to write it in here. Let me know if I am missing something obvious. Thanks!
