Heroku的Rails应用程序中包含两次jQuery [英] jQuery is included twice in Rails application on Heroku

问题描述

我的问题类似于其他一些问题，但仍然没有为我的情况提供答案。我在我的应用程序的Gemfile中包含jquery gem： / p>

  gem'jquery-rails'
  

在application.js中：

  // =需要jquery 
 // =要求jquery-ui 
 // =要求jquery_ujs 
 ... 
 // = require_tree。 
  

我的development.rb包含

 ＃不压缩资产
 config.assets.compress = false 
＃展开加载资产的行
 config.assets.debug = true 
  

我的资产没有预编译，没有公共/资产。
本地一切都运行良好。但是当我推送到heroku时，我在页面上获得了不同的application.js文件。它不是一个清单文件，而是缩小了jQuery的版本。所以我得到了两次jQuery。以下是我的页面源代码的样子：

 < script src =/ assets / jquery.js？body = 1 type =text / javascript>< / script> 
< script src =/ assets / jquery-ui.js？body = 1type =text / javascript>< / script> 
< script src =/ assets / jquery_ujs.js？body = 1type =text / javascript>< / script> 
 ... 
< script src =/ assets / application.js？body = 1type =text / javascript>< / script> 
  

当我点击 /assets/application.js?body=1 我看到缩小的jQuery。当我在本地运行我的应用程序并单击 /assets/application.js?body=1 时，我只能看到清单。
我尝试添加到development.rb中。

$ p $ config.serve_static_assets = false


没有帮助。我也清理了资产和缓存多次。
我唯一能做的就是设置

$ $ $ codeonfig.assets.debug = false
code>

但是我想知道是否有任何其他选项不会影响调试。

解决方案

我删除了这一行

  // = require_tree。 
  

并在javascripts中创建一个子文件夹，然后将javascript目录中的所有js文件移动到该子文件夹， strong> application.js

并写下此行

  // = require_tree ./sub_folder_name 
  

这是一个非常棒的工作。

请注意一件重要的事情：

这可能对您造成影响，因为您包含同一个文件两次通过 javascript_include_tag 和其他application.js手动执行。首先确认，如果是这种情况，您必须包括一次。

My question is similar to some other questions here which still didn't provide an answer for my situation

I am including jQuery gem in my app in Gemfile:

gem 'jquery-rails'

And in application.js:

//= require jquery
//= require jquery-ui
//= require jquery_ujs
...
//= require_tree .

My development.rb has

# Do not compress assets
config.assets.compress = false
# Expands the lines which load the assets
config.assets.debug = true

My assets are not precompiled, there is no public/assets. Everything is running great locally. But when I push to heroku I get different application.js file included on the page. Instead of being a manifest file it has minified version of jQuery. Therefore I get jQuery included twice. Here is how source of my page looks like:

<script src="/assets/jquery.js?body=1" type="text/javascript"></script>
<script src="/assets/jquery-ui.js?body=1" type="text/javascript"></script>
<script src="/assets/jquery_ujs.js?body=1" type="text/javascript"></script>
...
<script src="/assets/application.js?body=1" type="text/javascript"></script>

And when I click on /assets/application.js?body=1 I see minified jQuery. When I run my app locally and click on /assets/application.js?body=1 I just see the manifest. I tried to add to development.rb

 config.serve_static_assets = false

It didn't help. I also cleared assets and cache multiple times. The only thing that works for me is setting

config.assets.debug = false

But I would like to know if there is any other option that won't affect debugging.

解决方案

I removed this line

//= require_tree .

and creating a sub folder in javascripts and then moved all js files in javascript directory to that subfolder except application.js

and wrote this line

//= require_tree ./sub_folder_name

It's awsome and working.

One Important thing to Note:

This may cause to you as you are including a same file twice one manually by javascript_include_tag and other by application.js. First confirm that if this is the case you have to include it once.
