Rails 6中有许多默认路由吗？

Question

如何移除Rails 6中的默认路由？

我刚安装了Rails 6.0.0并运行'rails new blog'。我查看了路由并发现有大量的路由（见下文）。我尝试创建几个新项目，它们所有的默认路由都相同。

$ rake routes

我原本预计最多只有1个路由（主页）。

Answer 1

我也碰到了这个问题。如果您将以下代码添加到config/application.rb中，它将删除这些路由：

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 YourApp
  class Application < Rails::Application
    # Initialize configuration defaults for originally generated Rails version.
    config.load_defaults 6.0

    # CODE YOU SHOULD ADD vvvvvv
    initializer(:remove_action_mailbox_and_activestorage_routes, after: :add_routing_paths) { |app|
      app.routes_reloader.paths.delete_if {|path| path =~ /activestorage/}
      app.routes_reloader.paths.delete_if {|path| path =~ /actionmailbox/ }
    }
    # CODE YOU SHOULD ADD ^^^^^^^^

    # Settings in config/environments/* take precedence over those specified here.
    # Application configuration can go into files in config/initializers
    # -- all .rb files in that directory are automatically loaded after loading
    # the framework and any gems in your application.
  end
end

据我所知，这使用私有API来访问创建这些路由的文件，并将它们从路径中删除。我不知道这是否会将它们从生产环境中删除，而且由于它是私有API，很可能会在以后出现问题，但至少它可以清理bin/rails routes的输出结果。

有趣的发现。谢谢！ - Ahmed El Bannan

哇！这个完美地工作了。 - Erick

Answer 2

您可以通过在应用程序.rb文件中扩展需要 rails/all 的行，来完全删除现有应用程序中的 actionmailbox 功能（如果您正在升级rails或者你已经运行了rails new）。该文件仅包含默认的rails库。 请查看。

通过替换这一行，您不仅将排除路由，还将防止应用程序加载从未使用过的代码。

以下是示例，显示我的application.rb文件的顶部部分：

# config/application.rb

require_relative 'boot'

# Check out what rails/all.rb is currently expanded to:
#  https://github.com/rails/rails/blob/master/railties/lib/rails/all.rb
# Replace `require 'rails/all'` with just the libs that you want and 
# exclude the rest
require 'active_record/railtie'
# require 'active_storage/engine'
require 'action_controller/railtie'
require 'action_view/railtie'
require 'action_mailer/railtie'
require 'active_job/railtie'
require 'action_cable/engine'
# require 'action_mailbox/engine'
require 'action_text/engine'
require 'rails/test_unit/railtie'
require 'sprockets/railtie'

# the rest of your initialization follows here ...

Answer 3

我想目前还没有办法做到这一点。

对于ActiveStorage路由，您需要在config/application.rb中配置以下内容。

config.active_storage.draw_routes = false

• 这是链接，它不在当前稳定版本中，但它在下一个版本的主分支上。

对于ActionMailbox路由，即使在主分支上我也找不到任何东西。我猜下一个版本会有类似active_storage配置的内容。

谢谢，这应该会有所帮助。 - Ahmed El Bannan

是的，这有所帮助，但仍需要移除其他内容。做得很好！ - Erick

Answer 4

如果您在项目中不会使用这些功能，您应该运行

rails new blog --skip-active-storage --skip-action-mailer --skip-action-mailbox

您可以在那里查看新的Rails应用程序选项的完整列表。

rails new --help

顺便提一下：新的Rails应用程序默认不包含任何路由。请参阅Rails路由指南

请注意，Action Mailer 不会创建任何路由，问题中的所有路由都来自 Active Storage 和 Action Mailbox。 - arieljuod

Answer 5

在 config/application.rb 中替换这一行：

require "rails/all"

根据需要保留其内容并仅保留所需的铁轨连接器：

require "rails"

%w(
  active_record/railtie
  active_storage/engine
  action_controller/railtie
  action_view/railtie
  action_mailer/railtie  <-- REMOVE THIS!
  active_job/railtie
  action_cable/engine
  action_mailbox/engine  <-- REMOVE THIS!
  action_text/engine
  rails/test_unit/railtie
  sprockets/railtie
).each do |railtie|
  begin
    require railtie
  rescue LoadError
  end
end

然后从config/environments/*.rb中删除任何与邮件相关的配置
