所以这很有趣。我编辑了一个用户配置文件，它从我所知道的移植到heroku的数据库中。它现在在第15行下面，它的id为1.以下是连接到heroku数据库后控制台的输出：

出于某种原因，当我点击该用户名时，我得到的错误是，尽管数据库中明显存在该页面，但仍无法找到该页面。以下是网址到达该路线时的样子：
https://boiling-stream-6729.herokuapp.com/users/1
控制器很标准：
def show
@user = User.find(params[:id])
@allContributions = Payment.where(user_id: @user.id).to_a
@userContributions =[];
@allContributions.each{|c| @userContributions << Project.find(c.project_id)}
@allContributions
end
我去的任何其他个人资料，我没有这个问题，所以我只能得出结论是因为它已经在数据库中向下移动了。然而，我不明白什么是重要的，或者我应该怎么做。对于正在发生的事情以及做什么的任何意见表示赞赏！

您应先检查heroku log。我可以看到你的show方法做了很多事情，我确信有些事情失败了，因为它无法找到一些相关的资源。您的heroku log应该告诉您这一点。在这种情况下，最好先检查日志以查看确切的错误消息。
