#config.file_watcher = ActiveSupport::EventedFileUpdateChecker
config.file_watcher = ActiveSupport::FileUpdateChecker

FileUpdateChecker will detect by polling the change of the file.

Answer 3

This worked for me with ruby 2.6.5 and Rails 5.2.4.1.:

Add the following line in config/environments/development.rb:

config.file_watcher = ActiveSupport::EventedFileUpdateChecker

along with

config.cache_classes = false

in the same file, and

gem 'listen'

in the :development group in Gemfile.

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.

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)
