禁用ActiveRecord for Rails 4

Question

我想在Rails 4中禁用ActiveRecord。在 config/application.rbrequire File.expand_path('../boot', __FILE__)# require 'rails/all'  -- commentedrequire "action_controller/railtie"require "action_mailer/railtie"#require "active_resource/railtie" no need#require "rails/test_unit/railtie" no need#require "sprockets/railtie" no need# Require the gems listed in Gemfile, including any gems# you've limited to :test, :development, or :production.Bundler.require(:default, Rails.env)module MyApp  class Application < Rails::Application     config.app_middleware.delete "ActiveRecord::ConnectionAdapters::ConnectionManagement"  endend由于我有一个错误/home/alex/.rvm/gems/ruby-2.0.0-p247/gems/railties-4.0.0/lib/rails/railtie/configuration.rb:95:in   method_missing: undefined method active_record for #<Rails::Application::Configuration:0x00000002005c38> (NoMethodError)

Answer 1

嗨，这是默认的新new_app -O给出的结果

require "rails"

# Pick the frameworks you want: 

require "active_model/railtie" 

require "active_job/railtie"

# require "active_record/railtie" 

require "action_controller/railtie" 

require "action_mailer/railtie" 

require "action_view/railtie" 

require "sprockets/railtie" 

require "rails/test_unit/railtie"

在您的config / application.rb中

此外，它没有database.yml，也没有db / migrate / *和schema.rb

Answer 2

由于这仍然是搜索Google以禁用Rails 5的活动记录时的第一击，因此，请在此处添加以下内容：

对于Rails 5

执行@mechanicalfish答案中的所有步骤，但也删除该行

Rails.application.config.active_record.belongs_to_required_by_default = true

从

config/initializers/new_framework_defaults.rb
