为什么我的堆栈跟踪没有显示任何应用程序代码？

时间：2014-02-03 19:10:37

标签： ruby-on-rails ruby rake

运行rake任务bundle exec rake db:setup时出现错误，因为我无法连接到数据库。但是，堆栈跟踪永远不会显示我的应用程序或rails rake任务代码的来源。这是吐出的堆栈跟踪。

导致此堆栈跟踪的原因是什么？

更新

我知道问题的原因是无法访问数据库。我的问题：为什么我不能在stacktrace中看到哪些代码试图访问数据库？

答案 0 :(得分：0)

您正在看到调用它的代码。

bundle exec rake db:setup不是您创建的内容，因此不太可能引用您的代码。

代码由/Users/john/.rbenv/versions/jruby-1.7.9/lib/ruby/gems/shared/gems/activerecord-jdbc-adapter-1.3.5/lib/arjdbc/jdbc/connection.rb:23:in initialize'运行，由下面一行运行，等等。

我认为这些界限与您将变得有趣和相关的一样接近：
