ruby-on-rails - 我的 Rails Javascript list 文件既不编译也不包含任何必需的文件

Question

我看过一些与此类似的帖子，但没有解决方案，所以我想我会提出一个更详细的问题。

我的问题 list 文件中的 JS 不包含或编译任何 JS。

在本地运行我的服务器并打开 JS 文件时，我看不到任何编译内容，只有标准的 application.js list 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 development.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:

备注 ，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。所以我认为这很可能与一些未经处理的细节有关。

这个问题可以通过做..

$ rvm use ruby-2.0.0-p0

$ rails new project

使用 alert('hey') 创建一个 javascript 文件在其中 /assets/javascripts/

$ rails s

我认为这个问题是因为 Ruby 2 还不能与 Rails 一起工作:(

我将此正式确定为与 Rails 3.2.6 不兼容的 Ruby 2

Answer 1

Rajesh 的解决方案也对我有用。
我使用的是 2.0.0-p195 和 rake assets:precompile on production 并没有真正读取 application.js，我最终得到了大小为 1kb 的文件 application-###.js。

所以我回到 ruby​​ 1.9.3，更新包，手动清除缓存

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

进而

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

现在它起作用了。
