Question

当我在chrome上检查我的索引页面时，head标签有多个标签：

＆＃xA;＆＃xA;

 ＆lt; script src =“/ assets / components / questions / question_likes.self-6aaf2ce97062977185e0d5f9fc31643ca8fd012bfb53c12752977afdab1260be.js体= 1" 的数据turbolinks磁道= “真？” ＆GT;＆LT; /脚本＆GT;＆＃XA;＆LT; SCRIPT SRC =“/资产/ components.self-e3b0c44298fc1c149afbf4c8996fb92427ae41e4649b934ca495991b7852b855.js体= 1“data-turbolinks-track =”true“＆gt;＆lt; / script＆gt;＆＃xA;＆lt; script src =”/ assets / moment.self-0da3eb4ebf8fb8c3113d89afb90e5b7a87760d21b5b39a405a51fe05c8e40fd8.js？body = 1“data-turbolinks-track = “true”＆gt;＆lt; / script＆gt;＆＃xA;＆lt; script src =“/ assets / jquery-fileupload / vendor / jquery.ui.widget.self-92c37a41e67e528eecf100716907331b4b9aa4f546bf75ef2e0529c8c03a562d.js？body = 1”data-turbolinks-track =“true”＆gt;＆lt; / script＆gt;＆＃xA;＆lt; script src =“/ assets / jquery-fileupload / jquery.iframe-transport.self-e461f7ff2a60ee89459106a6f3e349cf79b7f56066b3c8cbc73389b30e1eb592.js？body = 1”data-turbolinks-track = “真正” ＆gt;＆lt; / script＆gt;＆＃xA;＆lt; script src =“/ assets / jquery-fileupload / jquery.fileupload.self-79c952fc273d5a8955a6093f4f489dcd509c5a2cefb2b9a049d3cdb2710ec8d3.js？body = 1”data-turbolinks-track =“true”＆gt;＆lt; ; / script＆gt;＆＃xA;＆lt; script src =“/ assets / jquery-fileupload / basic.self-6a3cf5192354f71615ac51034b3e97c20eda99643fcaf5bbe6d41ad59bd12167.js？body = 1”data-turbolinks-track =“true”＆gt;＆lt; / script＆gt;＆ #xA;＆lt; script src =“/ assets / jquery-fileupload / vendor / tmpl.self-c2108a63ad9ae9ab4a723bcf0104f6a92a63eb917331ff69fad6f02fe7219488.js？body = 1”data-turbolinks-track =“true”＆gt;＆lt; / script＆gt;＆＃xA; ＆lt; script src =“/ assets / s3_direct_upload.self-a71af1e40427c6623d982df253581eb58013b84d84f45bcef7d0352ad4e82534.js？body = 1”data-turbolinks-track =“true”＆gt;＆lt; / script＆gt;＆＃xA;＆lt; script src =“/ assets / application.self-c88a422e522d3887e663830741eb19213b74b0bcee8413fffde6decde58266aa.js？body = 1“data-turbolinks-track =”true“＆gt;＆lt; / script＆gt;＆＃xA;

我认为rails将所有js文件连接成一，为什么会发生这种情况？我正在使用反应，没有任何turbolinks。

在生产环境中运行时，Rails将创建一个可以使用javascript_include_tag引用的缩小的javascript文件。但是在开发和测试环境中，所有JavasScript文件都将包含在内，因为您已经显示出来以便于调试。

您可以在官方指南中read more about the Rails asset pipeline in development mode。

在开发模式下，资产按照清单文件中指定的顺序作为单独的文件提供。

此清单app / assets / javascripts / application.js：
//= require core
//= require projects
//= require tickets
会生成此HTML：
<script src="/assets/core.js?body=1"></script>
<script src="/assets/projects.js?body=1"></script>
<script src="/assets/tickets.js?body=1"></script>

指南还包括section discussing the config.assets.debug option，这是本案的问题（感谢@SergioTulentsev）。

为什么我在rails应用程序中有多个<script>标签而不是一个？
