我的Rails Javascript清单文件既不编译也不包含任何必需的文件

Question

我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.

来自清单文件的我的问题 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..

1. $ rvm use ruby-2.0.0-p0
2. $ rails new project
3. 以创建一个JavaScript文件,alert('hey')它在/assets/javascripts/
4. $ 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

Answer 1

Rajesh的解决方案也对我有用.我使用的是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.

Answer 2

我遇到了同样的问题，花了很长时间才找到解决方案。

我刚刚切换回ruby-1.9.3-p429，问题就解决了。我不知道如何管理它ruby 2 patches。我用过ruby-2.0.0-p247和ruby-2.0.0-p195。

所以，就这样做吧rvm use ruby-1.9.3-p429。然后运行“捆绑更新”。然后通过在控制台中运行来清除 Rails 缓存Rails.cache.clear，并且不要忘记清除浏览器缓存。

希望一切顺利。:)-
