Question

Hartl教程的Sample_app无法在线正常工作，但可以在本地服务器上运行。

问题是，当我点击帐户下拉按钮时，没有任何操作，只有“＃”符号出现在URL的末尾。我在某处读到了问题可能在app/assets/javascript/application.js文件中以及这部分代码的顺序：

//= require jquery
//= require jquery_ujs
//= require bootstrap
//= require turbolinks
//= require_tree .

我尝试了每个推荐的订单，但它仍然无效。有人有同样的问题吗？

Answer 1

我不知道该教程，但您是否预先编译了资产？

rake assets:precompile

这会将您的所有资产管道转换为生产服务器可以使用的内容。

在heroku上，你可能需要heroku run bundle exec rake assets:precompile

Answer 2

我遇到了同样的问题，这就是我所做的：

application.js文件如下：

//= require jquery  
//= require bootstrap  
//= require jquery_ujs  
//= require turbolinks  
//= require_tree .

production.rb代码如下：

 Rails.application.configure do
   # Settings specified here will take precedence over those in config/application.rb.

   # Code is not reloaded between requests.
   config.cache_classes = true

   # Eager load code on boot. This eager loads most of Rails and
   # your application in memory, allowing both threaded web servers
   # and those relying on copy on write to perform better.
   # Rake tasks automatically ignore this option for performance.
   config.eager_load = true

   # Full error reports are disabled and caching is turned on.
   config.consider_all_requests_local       = false
   config.action_controller.perform_caching = true

   # Enable Rack::Cache to put a simple HTTP cache in front of your application
   # Add `rack-cache` to your Gemfile before enabling this.
   # For large-scale production use, consider using a caching reverse proxy like nginx, varnish or squid.
   # config.action_dispatch.rack_cache = true

   # Disable Rails's static asset server (Apache or nginx will already do this).
   config.serve_static_assets = true #switched to true from false from advice on stackoverflow

   # Compress JavaScripts and CSS.
   config.assets.js_compressor = :uglifier
   # config.assets.css_compressor = :sass

   # Do not fallback to assets pipeline if a precompiled asset is missed.
   config.assets.compile = true #switched to true from false from advice on stackoverflow

   # Generate digests for assets URLs.
   config.assets.digest = true

   # `config.assets.precompile` and `config.assets.version` have moved to config/initializers/assets.rb

   # Specifies the header that your server uses for sending files.
   # config.action_dispatch.x_sendfile_header = "X-Sendfile" # for apache
   # config.action_dispatch.x_sendfile_header = 'X-Accel-Redirect' # for nginx

   # Force all access to the app over SSL, use Strict-Transport-Security, and use secure cookies.
   config.force_ssl = true #zzz: uncommented from rails tutorial

   # Set to :debug to see everything in the log.
   config.log_level = :info

   # Prepend all log lines with the following tags.
   # config.log_tags = [ :subdomain, :uuid ]

   # Use a different logger for distributed setups.
   # config.logger = ActiveSupport::TaggedLogging.new(SyslogLogger.new)

   # Use a different cache store in production.
   # config.cache_store = :mem_cache_store

   # Enable serving of images, stylesheets, and JavaScripts from an asset server.
   # config.action_controller.asset_host = "http://assets.example.com"

   # Ignore bad email addresses and do not raise email delivery errors.
   # Set this to true and configure the email server for immediate delivery to raise delivery errors.
   # config.action_mailer.raise_delivery_errors = false

   # Enable locale fallbacks for I18n (makes lookups for any locale fall back to
   # the I18n.default_locale when a translation cannot be found).
   config.i18n.fallbacks = true

   # Send deprecation notices to registered listeners.
   config.active_support.deprecation = :notify

   # Disable automatic flushing of the log to improve performance.
   # config.autoflush_log = false

   # Use default logging formatter so that PID and timestamp are not suppressed.
   config.log_formatter = ::Logger::Formatter.new

   # Do not dump schema after migrations.
   config.active_record.dump_schema_after_migration = false
 end

终端命令：

bundle exec rake assets:clean  
bundle exec rake assets:precompile  
bundle exec rake test  
git add -A  
git commit -m "finally fixing this dropdown menu"  
git push  
git push heroku

sample_app的帐户按钮在heroku上不起作用，但适用于本地服务器
