Rails Server needs restart every time I make changes? why?

Question

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 ?

My Rails version is 3.2.11

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

Please help..

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
