ruby-on-rails – My Rails Javascript清单文件既不编译也不包含任何必需的文件

我已经看过几篇类似的帖子,但没有解决方案,所以我想我会提出一个更有记录的问题.

清单文件中的我的问题JS不包括或编译任何JS.

在本地运行我的服务器,并打开JS文件时,我看不到任何编译,只是标准的application.js清单文件：

// This is a manifest file that'll be compiled into application.js,which will include all the files
// listed below.
//
// Any JavaScript/Coffee file within this directory,lib/assets/javascripts,vendor/assets/javascripts,// or vendor/assets/javascripts of plugins,if any,can be referenced here using a relative path.
//
// It's not advisable to add code directly here,but if you do,it'll appear at the bottom of the
// the compiled file.
//
// WARNING: THE FirsT BLANK LINE MARKS THE END OF WHAT'S TO BE PROCESSED,ANY BLANK LINE SHOULD
// GO AFTER THE REQUIRES BELOW.
//
//= require jquery
//= require jquery_ujs
//= require underscore
//= require backbone
//= require backbone_rails_sync
//= require backbone_datalink
//= require backbone/myapp
//= require_tree .

我的开发.rb：

MyApp::Application.configure do
  config.cache_classes = false  
  config.whiny_nils = true
  config.consider_all_requests_local       = true
  config.action_controller.perform_caching = false
  config.action_mailer.raise_delivery_errors = false
  config.active_support.deprecation = :log
  config.action_dispatch.best_standards_support = :builtin
  config.active_record.mass_assignment_sanitizer = :strict
  config.active_record.auto_explain_threshold_in_seconds = 0.5
  config.assets.compress = false
  config.assets.debug = true
end

我的application.rb：

require File.expand_path('../boot',__FILE__)

require 'rails/all'

if defined?(Bundler)
  Bundler.require(*Rails.groups(:assets => %w(development test)))
end

module MyApp
  class Application < Rails::Application
    config.encoding = "utf-8"
    config.filter_parameters += [:password]
    config.active_support.escape_html_entities_in_json = true
    config.active_record.whitelist_attributes = true
    config.assets.enabled = true
    config.assets.version = '1.0'
  end
end

我的日志：

需要注意的是,当我从MongoDB构建迁移到Postgres构建时,这个应用程序是从另一个应用程序中挑选出来的.所以我认为很可能,这与一些未经挑选的细节有关.

这个问题可以通过做..

> $rvm使用ruby-2.0.0-p0
> $rails新项目
>在/ assets / javascripts /中创建一个带有alert(‘hey’)的javascript文件
> $rails s

我认为这个问题是因为Ruby 2还没有与Rails一起使用:(

我将此正式定位为Ruby 2与Rails 3.2.6不兼容

解决方法

Rajesh的解决方案也对我有用.
我正在使用2.0.0-p195和rake资产：生产时的预编译并没有真正读取application.js而我最终得到了文件应用程序 – ###.js,大小为1kb.

所以我回到了ruby 1.9.3,更新了捆绑包,手动清除了缓存

rm -rf tmp/cache/assets/*
rm -rf tmp/cache/sass/*

然后

在我的application.js中,我有

//= require jquery
//= require bootstrap
//= require_tree .

请注意,我不使用jquery-ui或jquery_ujs

然后我跑了

rake RAILS_ENV=production RAILS_GROUP=assets assets:clean
rake RAILS_ENV=production RAILS_GROUP=assets assets:precompile

现在它有效.
