postgresql - Rails 4：#的未定义方法“结果”

Question

我有点被这个错误困住了。Postgres 正在运行，Rails 服务器也在运行，我在任何页面上都收到以下 NoMethodError：

undefined method `result' for #<TypeError: wrong argument type nil (expected Array)> 

应用程序跟踪不是很明确：

config/environments/development.rb:45:in `call'

提取的源代码（大约第 45 行）：

   previous_level = Rails.logger.level
   Rails.logger.level = Logger::ERROR if env['PATH_INFO'].index("/assets/") == 0
   @app.call(env)
 ensure
   Rails.logger.level = previous_level
 end

它可能与 PostgreSQL 适配器有关。

知道如何解决这个问题吗？

Ok, just got it after a while of tracking down to the bug source: it was a problem of character encoding between US-ASCII and UTF-8... a 'space' was not really a 'space' in my Gemfile.
