在轨道3.2.6中从开发切换到生产

标签: jquery css ruby-on-rails ruby-on-rails-3 asset-pipeline

我有使用Rails 3.2.6&的rails应用程序。 Ruby 1.9.3p0版本。我有多少CSS&我的资产文件夹中的JS(使用JQuery)文件带有资产管道。一切正常但我从开发到生产,压缩切换到名为application.css&的单个文件。 application.js然后我的 JQuery代码大部分都不起作用。我尝试了许多解决方案但没有任何帮助我。

请帮忙。谢谢。

这是我的application.html.erb

我的大多数JQuery代码都停止工作。

config.assets.initialize_on_precompile = false

^ application.rb中的那一行是告诉预编译函数懒惰地预编译。这意味着它将仅在您的主应用程序中预编译资产。如果将其设置为true,则可以预编译其他引用的Gems中包含的资源。因此,除非您的应用程序的资产文件夹中明确 jquery文件,否则可能会错过预编译 - 因此它不包含在您的application.js中。

注意

这一行:config.assets.compile = true应告诉您的应用程序在错过预编译资产的情况下回退到资产管道 - 理想情况下这意味着它会从中找到jquery资产正常的管道。

但是我的猜测是,因为技术上它找到了application.js,你的应用程序并不知道丢失了资产,所以它加载了预编译的{{1}然后,它无法获得application.js代码。

的解决方案

很抱歉有冗长的解释,但请尝试以下操作 - 在jquery

中设置以下一行
config/application.rb

config.assets.initialize_on_precompile

然后你当然要重建和重新部署:)让我知道这是否有帮助!!

宝石jquery-rails已有jquery-ui.min.js

您只需将此行添加到assets/javascript/application.js文件

即可

//= require jquery //= require jquery_ujs

并且只有application.html.erb

中的这一行

<%= javascript_include_tag "application" %>
