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 bef

Answer 1

An additional situation where this can come up is in a virtualized environment where the files are being edited on the host operating system, and the guest operating system's file event manager doesn't generate events for file changes.

A solution for this situation is to comment out the following line in config/environments/development.rb:

# 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

Thus giving:

# 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

This forces rails to actually check file modification times instead of expecting to get filesystem events.
