Ruby on rails Rails不记录数据库查询

我在development.rb中设置了以下行：

config.log_level = :debug

服务器正常启动，但仍然没有记录查询，我希望在日志中看到SELECT CREATE etc，但没有显示任何内容。我前一段时间安装了Exception，有没有可能会干扰常规日志？如果是，如何解决问题

根据答案的要求编辑1：

ls -la log/ :

cat ./Gemfile :

source 'http://rubygems.org'

gem 'rails', '3.0.3'
gem 'exceptional' #Logging system in production

group :development, :test do
  gem 'railroady'
end
# Bundle edge Rails instead:
# gem 'rails', :git => 'git://github.com/rails/rails.git'

gem 'sqlite3-ruby', :require => 'sqlite3'
gem 'paperclip', '~> 2.3'
gem 'aws-s3'
gem 'rails3-jquery-autocomplete'
# Use unicorn as the web server
# gem 'unicorn'

# Deploy with Capistrano
# gem 'capistrano'

# To use debugger (ruby-debug for Ruby 1.8.7+, ruby-debug19 for Ruby 1.9.2+)
# gem 'ruby-debug'
# gem 'ruby-debug19'

# Bundle the extra gems:
# gem 'bj'
# gem 'nokogiri'
# gem 'sqlite3-ruby', :require => 'sqlite3'
# gem 'aws-s3', :require => 'aws/s3'

# Bundle gems for the local environment. Make sure to
# put test-only gems in this group so their generators
# and rake tasks are available in development mode:
# group :development, :test do
#   gem 'webrat'
# end

再见，朱塞佩， 也许您使用的web服务器不记录此类内容，只是

tail -f log/development.log

在单独的控制台中。

尝试设置特定的RAILS\u ENV，如下所示：

RAILS\u ENV=开发RAILS服务器

但是不幸的是development.log没有记录我在environment.rb中设置的查询。什么都没有改变：如何在开发模式下运行rails应用程序？你能做一些事情吗：1。ls-la log/2。cat./gemfile一切正常，development.log已就位，容量为27Mb。似乎异常的gem从日志中捕获SQL查询。尝试将gem“Exception”转移到生产组
