title: Rails Server needs restart every time I make changes? why?
body: <p>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 ?</p>
  
  <p>My Rails version is <strong>3.2.11</strong></p>
  
  <p>In my development environment file i have <strong>set config.cache_classes = false.</strong></p>
  
  <p>Please help..</p>
  
  <p>My development.rb file is as follows</p>
  
  <pre><code>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 =&gt; 'localhost:3000' }
  
  end
