多年来,人们遇到了很多问题。我已经尝试了多种答案,但我仍然无法在我的 Rails 5.1.6 应用程序中将更新的样式表和 javascript 加载到 Heroku 中。它适用于我的本地机器。

这是我的文件。

应用程序/资产/样式表/application.scss

*= require_tree .
*= require_self

应用程序/视图/布局/application.html.erb

<html>
    <head>
      ......
      <%= stylesheet_link_tag    "application", media: "all" %>
      <%= csrf_meta_tags %>
      <%= favicon_link_tag "/favicon.ico" %>
      <%= render 'layouts/shim' %>
    </head>
    <body>
      ......
      <%= debug(params) if Rails.env.development? %>
      <%= javascript_include_tag "application" %>
    </body>
</html>

配置/应用程序.rb

require_relative 'boot'

require 'rails/all'

# Require the gems listed in Gemfile, including any gems
# you've limited to :test, :development, or :production.
Bundler.require(*Rails.groups)

module EzklwRor
  class Application < Rails::Application
    # Initialize configuration defaults for originally generated Rails version.
    config.load_defaults 5.1

    # Settings in config/environments/* take precedence over those specified here.
    # Application configuration should go into files in config/initializers
    # -- all .rb files in that directory are automatically loaded.

    RouteTranslator.config do |config|
      config.generate_unnamed_unlocalized_routes = true
      config.locale_param_key                    = :locale
    end

    config.exceptions_app = self.routes     
    config.action_dispatch.default_headers = { 'X-Frame-Options' => 'ALLOWALL' }
  end
end

配置/环境/production.rb

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.

  # Disable serving static files from the `/public` folder by default since

  # Use the lowest log level to ensure availability of diagnostic information
  # when problems arise.
  config.log_level = :debug

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

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

  # Use a real queuing backend for Active Job (and separate queues per environment)
  # config.active_job.queue_adapter     = :resque

  config.action_mailer.perform_caching = 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 = [I18n.default_locale]

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

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

  # Use a different logger for distributed setups.

  end

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

这是我在本地机器上所做的。

rake assets:clean

rake assets:precompile

rake assets:precompile RAILS_ENV=production

committed changes with public/assets folder included using Github desktop app

git push heroku master

git push heroku master -f when initial change did not work after adding spaces to a file to avoid everything-up-to-date message.

heroku rake assets:precompile RAILS_ENV=production

heroku restart several times along the way

heroku repo:clone -a myapp to verify that my app/assets folder was up to date

heroku repo:reset -a myapp to empty the heroku repo

git push heroku master

heroku logs -t

我已经多次清除浏览器中的缓存,重新启动计算机并在不同设备上显示新应用程序。我在 heroku 日志中没有看到任何错误。我的 css 和 js 不工作。我还能在哪里解决这个问题?

我检查了你的配置文件,config/environments/production.rb你有一个错误config.serve_static_assets = true;因此,您需要更改为config.public_file_server.enabled = true,并且请更改,config.assets.compile = false因为我认为您不想在每个请求中都编译资产。

这是类似的用法:config/environments/production.rb
