每次我进行更改时，Rails Server 都需要重新启动吗?为什么? [英] Rails Server needs restart every time I make changes? why?

问题描述

每次我更改控制器或模型中的任何内容时，我都必须重新启动服务器才能使其生效.但情况并非总是如此，以前它可以正常工作，当我更改任何内容时，但我不这样做不知道现在发生了什么?

Every time I change anything in controller's or in models, I have to restart the server for it to take effect.But that wasn't always the case, it used to work normally before, when I changed anything, but i don't know what happened now ?

我的 Rails 版本是 3.2.11

My Rails version is 3.2.11

在我的开发环境文件中，我设置了 config.cache_classes = false.

In my development environment file i have set config.cache_classes = false.

请帮忙..

我的development.rb文件如下

My development.rb file is as follows

Testapp::Application.configure do
  # Settings specified here will take precedence over those in config/application.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 web server when you make code changes.
  config.cache_classes = false

  # Log error messages when you accidentally call methods on nil.
  config.whiny_nils = true

  # Show full error reports and disable caching
  config.consider_all_requests_local       = true
  config.action_controller.perform_caching = false

  # Don't care if the mailer can't send
  config.action_mailer.raise_delivery_errors = false

  # Print deprecation notices to the Rails logger
  config.active_support.deprecation = :log

  # Only use best-standards-support built into browsers
  config.action_dispatch.best_standards_support = :builtin

  # Raise exception on mass assignment protection for Active Record models
  config.active_record.mass_assignment_sanitizer = :strict

  # Log the query plan for queries taking more than this (works
  # with SQLite, MySQL, and PostgreSQL)
  config.active_record.auto_explain_threshold_in_seconds = 0.5

  # Do not compress assets
  config.assets.compress = false

  # Expands the lines which load the assets
  config.assets.debug = true

  config.action_mailer.default_url_options = { :host => 'localhost:3000' }

end
