It should not be necessary to restart Rails server after any normal change. However, when I make little changes on my app controllers, they aren't applied if I don't restart the server. Even if I wrote bad code and made errors intentionally, the old error persists. How can I change that or verify that's well set up?

I have in config/environment/development.rb file:

config.cache_classes = false

This didn't work for me.

UDPATE 1:

development.rb

    Rails.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



  # Do not eager load code on boot.

  config.eager_load = false



  # 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



  # Raise an error on page load if there are pending migrations.

  config.active_record.migration_error = :page_load



  # Debug mode disables concatenation and preprocessing of assets.

  # This option may cause significant delays in view rendering with a large

  # number of complex assets.

  config.assets.debug = true



  # Asset digests allow you to set far-future HTTP expiration dates on all assets,

  # yet still be able to expire them through the digest params.

  config.assets.digest = true



  # Adds additional error checking when serving assets at runtime.

  # Checks for improperly declared sprockets dependencies.

  # Raises helpful error messages.

  config.assets.raise_runtime_errors = true



  # Raises error for missing translations

  # config.action_view.raise_on_missing_translations = true

end

You can use nodemon for auto restarting rails applications.

1) Install nodemon.

sudo npm install -g nodemon

2) Create nodemon.json file on root dir and configure it

{

  "ignore": [

    ".git",

    "node_modules/**/node_modules"

  ],

  "watch": [

    "app/controllers/",

    "app/models/",

    "app/assets/",

    "config/",

    "db/"

  ],

  "ext": "rb yml js css scss"

}

3) Create rails.sh file on root dir to start rails application using nodemon.

kill -9 `cat tmp/pids/server.pid`

echo "APP READY!!!"

echo "Ruby on Rails"

rails s -d

4) Give permission to rails.sh file.

sudo chmod +x rails.sh

5) Start server using sh command.

nodemon -L --exec "./rails.sh"

Note: Steps verified on mac machine. different os may have different command or configuration.
