javascript_include_tag 的 Ruby On Rails 错误

【问题标题】：Ruby On Rails errors with javascript_include_tagjavascript_include_tag 的 Ruby On Rails 错误
【发布时间】：2015-04-29 21:40:36
【问题描述】：

因此，据我所知，我的问题似乎是 ruby​​ 没有加载其所有 javascript 文件，因为我没有收到确认消息和 link_to with method: :delete 对我没有任何作用。

使用提供给我的默认设置 rails new

views/layouts/application.html.erb head部分如下。

<head>
  <title>Myrubyblog</title>
  <%= stylesheet_link_tag    'default', media: 'all', 'data-turbolinks-track' => true %>
  <%= javascript_include_tag 'default', 'data-turbolinks-track' => true%>
  <%= csrf_meta_tags %>
</head>

这给了我错误

当我将 stylecheet_link_tag 和 javascript_include_tag 更改为使用 :default 而不是 'default' 时也会发生此错误。

这个错误似乎是因为 /javascripts/default.js 不存在，所以我发现这两篇文章说 :default 不再支持。

Rails 4 link_to Destroy not working in Getting Started tutorial

Delete link sends "Get" instead of "Delete" in Rails 3 view

将“默认”更改为“应用程序”后，出现以下错误。

views/layouts/application.html.erb head部分如下。

<head>
  <title>Myrubyblog</title>
  <%= stylesheet_link_tag    'application', media: 'all', 'data-turbolinks-track' => true %>
  <%= javascript_include_tag 'application', 'data-turbolinks-track' => true%>
  <%= csrf_meta_tags %>
</head>

有人知道我的问题是什么吗？

如果需要，我的路线和 gemfile 供参考。

routes.rb

Rails.application.routes.draw do
  get 'categories/index'

  get 'categories/edit'

  get 'categories/new'

  get 'categories/show'

  get 'home/index'

  resources :posts
  resources :categories

  root 'home#index'
end

【问题讨论】：

  • 我猜应该是:defaults。
  • 我也尝试过使用 :defaults。它所做的只是尝试打开也不存在的 /javascripts/defaults.js。
  • 你找到这个错误的答案了吗？

【解决方案1】：

将两行中的“默认值”改回“应用程序”

在 gem 文件中插入：

gem 'coffee-script-source', '1.8.0'

然后在命令提示符下运行：

bundle update coffee-script-source

解决了我的问题，希望它也解决了你的问题:)

【讨论】：

  • 为什么是 1.8.0 ？我不得不从 1.10.0 降级到 1.8.0 ......为什么？怎么了 ？我将不胜感激。
  • @RareFever 我不认为 'coffee-script-source 1.9 和 > 在 windows 上工作。
  • 是的，你是对的。 Windows...感谢您的回答！
【解决方案2】：
  1. 将两行中的“默认值”改回“应用程序”
  2. 在 gem 文件中插入： gem 'coffee-script-source', '1.8.0'
  3. 然后在命令提示符下运行： 捆绑更新咖啡脚本源

Figjeti 的这个答案也对我有用。 :)

  • 不要添加谢谢作为答案。这是评论多于答案。
