ruby-on-rails - eager_load 崩溃在生产中启动
问题描述
eager_load = true 将在启动时使应用程序崩溃。这已经在我的本地机器和尝试在生产中启动的服务器上进行了测试。将 eager_load 设置为 false 将解决问题，但我希望加载急切。
我检查了堆栈跟踪，看不到任何未定义的变量。我在开发中将 eagerload 设置为 true，它可以正常工作，这很奇怪。
我检查并测试了所有控制器和模型，以防某些东西被加载而没有被定义。

我希望开发服务器不以 eager_load true 启动，或者生产服务器以 eager_load true 启动。很奇怪 eager_load 在开发中有效，但在生产中无效。
