每次我更改控制器或模型中的任何内容时,我都必须重新启动服务器,让它获取effect.But。这并不总是这样,它以前是正常工作的,当我更改任何内容时,但我不知道现在发生了什么?
我的Rails版本是3.2.11
在我的开发环境文件中,我让设置了config.cache_classes =false。
请帮帮我..
我的development.rb文件如下
Testapp::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
# Log error messages when you accidentally call methods on nil.
config.whiny_nils = true
# 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
# Only use best-standards-support built into browsers
config.action_dispatch.best_standards_support = :builtin
# Raise exception on mass assignment protection for Active Record models
config.active_record.mass_assignment_sanitizer = :strict
# Log the query plan for queries taking more than this (works
# with SQLite, MySQL, and PostgreSQL)
config.active_record.auto_explain_threshold_in_seconds = 0.5
# Do not compress assets
config.assets.compress = false
# Expands the lines which load the assets
config.assets.debug = true
config.action_mailer.default_url_options = { :host => 'localhost:3000' }
end

我已经得到了答案..
在我的config/environments/development.rb
文件中添加以下行之后,我的问题就解决了。
config.reload_classes_only_on_change = false

在控制台中使用以下命令启动您的服务器
rails server -e development
如果未启动,请提供您的rails版本以及用于运行rails应用程序的服务器。
更多配置
将您的config/environments/development.rb
文件修改为:
config.serve_static_assets = false

出现这种情况的另一种情况是在虚拟化环境中,文件在主机操作系统上进行编辑,而来宾操作系统的文件事件管理器不会为文件更改生成事件。
这种情况的解决方案是在config/environments/development.rb
中注释掉以下行:
# 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
因此,提供了:
# 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
这迫使rails实际检查文件修改时间,而不是期望获得文件系统事件。
