配置在特定于环境的配置文件中未定义 [英] config undefined in environment specific configuration files

问题描述

当我在本地启动服务器时，收到以下通知:

When I start my server locally, I get the following notice:

please set config.active_support.deprecation to :log at config/environments/development.rb

当我添加 config/environments/development.rb 时

When I add in config/environments/development.rb

config.active_support.deprecation = :log 

我明白了:

undefined local variable or method `config' for main:Object (NameError)

我的环境:Rails 3.0.1 Ruby 1.8.7 Ubuntu 10.04

my environment: Rails 3.0.1 Ruby 1.8.7 Ubuntu 10.04

Development.rb 文件

Development.rb file

# Settings specified here will take precedence over those in config/environment.rb

# In the development environment your application's code is reloaded on
# every request.  This slows down response time but is perfect for development
# since you don't have to restart the webserver when you make code changes.
config.active_support.deprecation = :log
config.cache_classes = false

推荐答案

在你的 development.rb 中，它应该有一个如下所示的块:

In your development.rb it should have a block that looks like:

YourApplicationName::Application.configure do
   config.active_support.deprecation = :log
   config.cache_classes = false
end

配置行必须放在那个块内.

The config lines must be placed inside that block.
