ruby-on-rails-3 - Rails 3 Coffee Handler丢失

Question

我在生产中使用的是Ruby 1.9.3p0，Rails 3.1.2，Apache和Passenger。当我尝试做一个远程功能时，它引发了这个错误:

ActionView::MissingTemplate (Missing template video/loadVideo, application/loadVideo with
{:handlers=>[:erb, :builder], :formats=>[:js, "application/ecmascript", "application/x-
ecmascript", :html, :text, :js, :css, :ics, :csv, :xml, :rss, :atom, :yaml, 
:multipart_form, :url_encoded_form, :json], :locale=>[:en, :en]}. Searched in

如您所见，没有 :coffee 的处理程序，这就是为什么不处理文件 video/loadVideo.js.coffee 的原因；我运行命令 rake asset:precompile ，但没有任何变化。

gem 文件

gem 'rails', '3.1.2'

# Bundle edge Rails instead:
# gem 'rails',     :git => 'git://github.com/rails/rails.git'

gem 'will_paginate', '~> 3.0'
gem "bcrypt-ruby", :require => "bcrypt"
gem 'mysql'

group :test do
  # Pretty printed test output
  gem 'turn', '0.8.2', :require => false
end

Answer 1

更改您的Gemfile(将咖啡栏上的 gem 移到 Assets 组之外)或更改application.rb设置-例如

if defined?(Bundler)
  # If you precompile assets before deploying to production, use this line
  # Bundler.require(*Rails.groups(:assets => %w(development test)))
  # If you want your assets lazily compiled in production, use this line
  Bundler.require(:default, :assets, Rails.env)
end

在开发环境中，默认情况下，应用程序从 :default, :development, :test, :assets组中加载所有gem。咖啡处理程序来自 coffee-rails gem，因此您必须加载它。
