Rails服务器看不到代码更改和重新加载文件
我注意到我的rails服务器在更改后没有重新加载控制器，模型和可能的任何其他文件。 我使用Vagrant和Rails API，我发现有些人通过在Vagrantfile添加以下行来解决这个问题。
config.vm.provider "virtualbox" do |vb| vb.customize [ "guestproperty", "set", :id, "/VirtualBox/GuestAdd/VBoxService/--timesync-set-threshold", 5000 ] end
它不能解决我的问题。 我没想到我还能做些什么来解决这个问题。 我附上可能对您有用的文件。
我的Gemfile看起来像这样：
source 'https://rubygems.org' gem 'rake', '= 5.0.0.beta3', '= 0.3.18', ' 0.18' gem 'active_model_serializers' gem 'rspec-its' gem 'database_cleaner' # Use Puma as the app server gem 'puma' # Build JSON APIs with ease.

我确信我在开发模式下运行我的服务器，因为日志的开始
=> 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
这是我的development.rb文件
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
我的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
它不能解决我的问题。
添加到config/environments/development.rb
#config.file_watcher = ActiveSupport::EventedFileUpdateChecker config.file_watcher = ActiveSupport::FileUpdateChecker
FileUpdateChecker将通过轮询文件的更改来检测。
我已经解决了我的问题，将以下行添加到development.rb文件中。
config.reload_classes_only_on_change = false
pocari的解决方案对我有用，但我不得不在页面重新加载之前等待几秒钟，否则内容并不总是更新。
如本答案中所述，向synced_folder添加选项工作正常：
config.vm.synced_folder ".", "/vagrant", type: "nfs", mount_options: ['actimeo=1']
（并且没有必要改变development.rb ）
我遇到了同样的问题所以我所做的就是像这样做一个快速的脚本。 确保您首先在app文件夹中。
!#/bin/bash rake db:migrate echo "MIGRATED" rake routes echo "routed" sudo service apache2 restart echo "web server reloaded"
现在你可以输入./bump它将运行所有三个命令，然后你知道所有内容都已加载。 我也使用这种方法重复这个，就像命令行安装gem一样。
