我正在尝试使用mongodb将rails应用程序部署到heroku，但不断收到错误：
NoMethodError: undefined method `active_record' for #<Rails::Application::Configuration:0x007fb2d41e17f0>
...
Precompiling assets failed.
我在问之前已经尝试了所有内容，例如以下的解决方案 - （Heroku Precompiled Assets Failed，Ruby on Rails Precompiling assets failed）但我仍然无法使其发挥作用
1。 当我创建应用程序时，我使用-O选项跳过活动记录：
rails new app -T -O
2。 我删除了sqlite3。这是Gemfile：
source 'https://rubygems.org'
gem 'rails', '4.1.8'
gem 'sass-rails', '~> 4.0.3'
gem 'uglifier', '>= 1.3.0'
gem 'coffee-rails', '~> 4.0.0'
gem 'jquery-rails'
gem 'turbolinks'
gem 'jbuilder', '~> 2.0'
gem 'sdoc', '~> 0.4.0', group: :doc
gem 'spring', group: :development
group :production do
gem 'mongoid', github: "mongoid/mongoid"
end
gem 'bson_ext'
gem "omniauth-twitter"
gem "figaro", "~> 0.7.0"
gem "heroku"
group :production do
gem 'thin'
end
第3。 在application.rb中，我添加了：
config.assets.initialize_on_precompile = false
...并注释掉文件顶部需要'rails / all'：
# require 'rails/all'
require "action_controller/railtie"
require "action_mailer/railtie"
# require "active_resource/railtie"
require "sprockets/railtie"
4。 在production.rb中，我注释掉了：
config.active_record.dump_schema_after_migration = false
5。 在mongoid.yml文件中，我添加了ENV ['MONGOHQ_URL']。这是文件：
development:
# Configure available database sessions. (required)
sessions:
# Defines the default session. (required)
default:
# Defines the name of the default database that Mongoid can connect to.
# (required).

# default, unless for some reason you absolutely need to limit the
# pool_size, as this wait is only used when the pool is saturated.

# The time in seconds before Moped will timeout connection and node
# operations. (default: 5)

# Whether connections should use SSL. (default: nil/false)
# ssl: false
# Whether Moped will use the existing seeds/nodes to find other peers.
# (default: true)
# auto_discover: true
# Configure Mongoid specific options. (optional)
options:

# include_root_in_json: false
# Include the _type field in serialization. (default: false)

# Ensure all times are UTC in the app side. (default: false)
# use_utc: false
test:

6。在推送到heroko master之前，我输入了命令：
RAILS_ENV=production bundle exec rake assets:precompile
git add .
git commit -am 'precompiled assets'
git push heroku
7。 这是完整的错误：

无论如何，我完全被难过了。任何帮助将非常感激。 感谢

我认为你需要删除这一行：
config.active_record.dump_schema_after_migration = false
您的应用程序未加载active_record，因此您无需进行配置。
答案 1 :(得分：0)
在config / application.rb
上# Enable the asset pipeline
config.assets.enabled = true
适合我！
