javascript - javascript_include_tag 的 Ruby On Rails 错误

所以据我所知，我的问题似乎是 ruby​​ 没有加载它的所有 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 stylescheet_link_tag 和 javascript_include_tag 更改为使用 :default 而不是 'default' 时，也会发生此错误。

这个错误好像是因为/javascripts/default.js 不存在，所以我找到了这两篇文章说 :default is no longer supported。

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 供引用。

路线.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

gem 文件

source 'https://rubygems.org'


# Bundle edge Rails instead: gem 'rails', github: 'rails/rails'
gem 'rails', '4.1.8'
# Use sqlite3 as the database for Active Record
#gem 'sqlite3'
gem 'pg'
# Use SCSS for stylesheets
gem 'sass-rails', '~> 4.0.3'
# Use Uglifier as compressor for JavaScript assets
gem 'uglifier', '>= 1.3.0'
# Use CoffeeScript for .js.coffee assets and views
gem 'coffee-rails', '~> 4.0.0'
# See https://github.com/sstephenson/execjs#readme for more supported runtimes
# gem 'therubyracer',  platforms: :ruby

# Use jquery as the JavaScript library
gem 'jquery-rails'
# Turbolinks makes following links in your web application faster. Read more: https://github.com/rails/turbolinks
gem 'turbolinks'
# Build JSON APIs with ease. Read more: https://github.com/rails/jbuilder
gem 'jbuilder', '~> 2.0'
# bundle exec rake doc:rails generates the API under doc/api.
gem 'sdoc', '~> 0.4.0',          group: :doc

# Use ActiveModel has_secure_password
# gem 'bcrypt', '~> 3.1.7'

# Use unicorn as the app server
# gem 'unicorn'

# Use Capistrano for deployment
# gem 'capistrano-rails', group: :development

# Use debugger
# gem 'debugger', group: [:development, :test]

# Windows does not include zoneinfo files, so bundle the tzinfo-data gem
gem 'tzinfo-data', platforms: [:mingw, :mswin]

最佳答案

将两行中的“默认值”改回“应用程序”

将其插入到 gem 文件中:

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，希望它也能解决你的问题:)
