RAILS_ENV 更改内容 app/layouts/application.html.erb 内容
RAILS_ENV changing the content of app/layouts/application.html.erb content
我正在开发一个 rails 应用程序,并且最近将 app/layouts/application.html.erb
的 <%= javascript_include_tag "application" %>
行移动到了 </body>
标签的正下方。
当我以开发模式启动服务器并查看 localhost:3000 的源代码时,我按预期看到了结束正文标记下方的 javascript。但是,当我在生产模式下启动服务器时,javascript 出现在它原来的位置,在 <head>
标记中。
其他人是否知道在 development/production 环境中可能导致对 app/layouts/application.html.erb
文件的这种不同解释的原因?其他人可以提供的任何指示将不胜感激。
This is an introduction to three types of caching techniques: page,
action and fragment caching. By default Rails provides fragment
caching. In order to use page and action caching you will need to add
actionpack-page_caching
and actionpack-action_caching
to your
Gemfile
.
By default, caching is only enabled in your production environment. To play around with caching locally you'll want to
enable caching in your local environment by setting
config.action_controller.perform_caching
to true
in the relevant
config/environments/*.rb file:
config.action_controller.perform_caching = true
您只需要清除缓存文件,因为 rails 在生产环境中默认缓存这些文件。
