ruby-on-rails - Rails 开发日志文件中缺少有关参数和渲染部分的信息

Question

这是正常的 Rails 3.2 日志文件条目的样子:

Started GET "/admin" for 127.0.0.1 at 2013-08-05 14:36:43 +0200  
Processing by Admin::PagesController#show as HTML  
  Parameters: {"id"=>"admin/dashboard"}  
  Post Load (1.5ms)  SELECT 'posts'.* FROM 'posts' WHERE 'posts'.'riddle' = 1 AND 'posts'.'solved_at' <= '2013-08-05 12:36:43' ORDER BY comments_count DESC LIMIT 1  
  [...]  
  CACHE (0.0ms)  SELECT 'comments'.* FROM 'comments' WHERE 'comments'.'post_id' = 74 ORDER BY 'comments'.'id' DESC LIMIT 1  
   (0.3ms)  SELECT COUNT(*) FROM 'posts' WHERE 'posts'.'riddle' = 1  
  Rendered admin/dashboard.html.haml within layouts/admin (109.1ms)  
  Rendered shared/admin/_header.html.haml (3.8ms)  

问题:在我的一个应用程序中，前导 Processing ... 和 Parameters: ... 以及尾随 Rendered ... 缺少几行，我一辈子都弄不明白为什么!

   (0.3ms)  SELECT COUNT(*) FROM 'posts' WHERE 'posts'.'riddle' = 1  

该应用程序太大，包含太多 gem ，无法在此处发布相关部分，但我尝试在开发中删除 gem ，验证日志级别设置为 :debug，记录器是标准的一个等等

有人见过这个吗？

检查 ActionController::Base 使用的 Logger 是否与应用其余部分使用的相同。在 Rails 控制台中，ActionController::Base.logger == Rails.logger 应该是 true。

如果它是 false，那么应用程序正在某处为 ActionController::Base 设置一个特定的 Logger，使用类似 的东西ActionController::Base.logger = ActiveSupport::TaggedLogging.new(Logger.new('log/controllers.log'))
