我的应用程序在开发环境中工作，但在Heroku中有一些图像，字体和js函数无效。
我现在要在一张图片上磨练。主页应加载位于
的图像资产/图像/图形/ blue_pattern.gif
在我的SCSS文件中，我有：
image-url("patterns/blue_pattern.gif")
我的Heroku日志包含以下内容：
2017-04-11T10：39：54.873200 + 00:00 heroku [router]：at = info method = GET 路径= “/图片/图形/ blue_pattern.gif” 主机= matchmeplease.herokuapp.com request_id = cf0c2d58-a616-484f-b659-cd4cbfe94118 fwd =“115.70.240.190” dyno = web.1 connect = 2ms service = 5ms status = 404 bytes = 1789 协议= HTTPS
我会诚实地说我不完全理解配置文件。
我的config / environments / production.rb文件：
Rails.application.configure do
config.force_ssl = true
config.cache_classes = true
config.eager_load = true
config.consider_all_requests_local = false
config.action_controller.perform_caching = true
config.public_file_server.enabled = false
config.assets.js_compressor = :uglifier
config.assets.css_compressor = :sass
config.assets.compile = true
config.assets.digest = true
config.log_level = :debug
config.i18n.fallbacks = true
config.active_support.deprecation = :notify
config.log_formatter = ::Logger::Formatter.new
config.active_record.dump_schema_after_migration = false
config.serve_static_assets = true
end
配置/ application.rb中：
require_relative 'boot'
require 'rails/all'
require 'geocoder'
require "geocoder/railtie"
Geocoder::Railtie.insert
# Require the gems listed in Gemfile, including any gems
# you've limited to :test, :development, or :production.
Bundler.require(*Rails.groups)
module MatchMe
class Application < Rails::Application
config.assets.paths << Rails.root.join("app", "assets", "font")
end
end
编辑：在关注Uday kumar das'评论后（见下文）我现在有图像和字体工作，但我的js文件由于某种原因仍然没有加载。
当我运行RAILS_ENV=production bundle exec rake assets:precompile时，我得到以下内容：
rake aborted!

我不确定为什么这是因为我的AWS S3功能在我的应用程序中完美运行。
答案 0 :(得分：1)
在config/application.rb添加以下代码并bundle添加：
config.serve_static_assets = true
gem 'rails_12factor', group: :production
此次运行后RAILS_ENV=production bundle exec rake assets:precompile。
