[英]Restart Rails server automatically after every change in controllers
在任何正常更改后,不需要重新启动 Rails 服务器。 但是,当我对我的应用程序控制器进行少量更改时,如果我不重新启动服务器,它们就不会应用。 即使我写了错误的代码并故意犯了错误,旧的错误仍然存在。 我该如何更改或验证设置是否正确?
我在config/environment/development.rb file
:
config.cache_classes = false
这对我不起作用。
UDPATE 1:
发展.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
您可以使用nodemon自动重新启动旧的 rails 应用程序。
1) 安装 nodemon。
sudo npm install -g nodemon
2) 在 root 目录上创建nodemon.json文件并配置它
{
"ignore": [
".git",
"node_modules/**/node_modules"
],
"watch": [
"app/controllers/",
"app/models/",
"app/assets/",
"config/",
"db/"
],
"ext": "rb yml js css scss"
}
3) 在根目录上创建rails.sh文件以使用 nodemon 启动 rails 应用程序。
kill -9 `cat tmp/pids/server.pid`
echo "APP READY!!!"
echo "Ruby on Rails"
rails s -d
4) 授予rails.sh
文件权限。
sudo chmod +x rails.sh
5) 使用sh
命令启动服务器。
nodemon -L --exec "./rails.sh"
注意:在mac机器上验证的步骤。 不同的操作系统可能有不同的命令或配置。
