问题
I noticed that my rails server doesn't reload controllers, models and probably any other files after I change them. I use Vagrant and Rails API, and I found that some people fix this problem by adding below line to the Vagrantfile.
config.vm.provider "virtualbox" do |vb|
vb.customize [ "guestproperty", "set", :id, "/VirtualBox/GuestAdd/VBoxService/--timesync-set-threshold", 5000 ]
end
It doesn't fix the problem for me. I run out of the ideas what else I can do to solve this problem. I attach files which might be useful for you.
My Gemfile looks like this:
source 'https://rubygems.org'
gem 'rake', '< 11.0'
# Bundle edge Rails instead: gem 'rails', github: 'rails/rails'
gem 'rails', '>= 5.0.0.beta3', '< 5.1'

I'm sure that I run my server in development mode, because of the beggining of the log
=> Booting Puma
=> Rails 5.0.0.beta3 application starting in development on http://0.0.0.0:3000
=> Run `rails server -h` for more startup options
=> Ctrl-C to shutdown server
Puma starting in single mode...
* Version 3.1.0 (ruby 2.2.3-p173), codename: El Niño Winter Wonderland
* Min threads: 5, max threads: 5
* Environment: development
* Listening on tcp://0.0.0.0:3000
This is my development.rb file
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.
config.consider_all_requests_local = true
# Enable/disable caching. By default caching is disabled.
if Rails.root.join('tmp/caching-dev.txt').exist?
config.action_controller.perform_caching = true
config.action_mailer.perform_caching = false
config.cache_store = :memory_store
config.public_file_server.headers = {
'Cache-Control' => 'public, max-age=172800'
}
else
config.action_controller.perform_caching = false
config.action_mailer.perform_caching = false
config.cache_store = :null_store
end
# 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
# Raises error for missing translations
# config.action_view.raise_on_missing_translations = true
# Use an evented file watcher to asynchronously detect changes in source code,
# routes, locales, etc. This feature depends on the listen gem.
config.file_watcher = ActiveSupport::EventedFileUpdateChecker
end
My Vagrantfile
Vagrant.configure(2) do |config|
if Vagrant.has_plugin?("vagrant-timezone")
config.timezone.value = "Europe/Warsaw"
end
config.vm.box = "ubuntu/trusty64"
config.vm.network :forwarded_port, guest: 3000, host: 3000
config.vm.synced_folder "E:/Projekty - Rails", "/home/projekty"
config.vm.provider "virtualbox" do |vb|
vb.customize [ "guestproperty", "set", :id, "/VirtualBox/GuestAdd/VBoxService/--timesync-set-threshold", 5000 ]
end
end

It doesn't fix the problem for me.
add to the config/environments/development.rb
#config.file_watcher = ActiveSupport::EventedFileUpdateChecker
config.file_watcher = ActiveSupport::FileUpdateChecker
FileUpdateChecker will detect by polling the change of the file.

I've solved my problem adding below line to the development.rb file.
config.reload_classes_only_on_change = false

pocari's solution worked for me but I had to wait a few seconds before a page reload, otherwise the content was not always updated.
Adding an option to the synced_folder as described in this answer worked fine:
config.vm.synced_folder ".", "/vagrant", type: "nfs", mount_options: ['actimeo=1']
(and the change in development.rb is not necessary)

I was having the same issue so what I did was make a quick script bump like this. Make sure you are in your app folder first.
!#/bin/bash
rake db:migrate
echo "MIGRATED"
rake routes
echo "routed"
sudo service apache2 restart
echo "web server reloaded"
Now you can just type ./bump and it will run all three commands then you know everything is loaded. I also use this method to repeat this like the command line installs for gems such as devise.
