rails 6 中的许多默认路由？

Question

如何删除 Rails 6 中的默认路由？

我刚刚安装了 Rails 6.0.0 和运行 'rails new blog'。我去看看路线，发现了很多路线（见下文）。我试过创建几个新项目，它们都有相同的默认路由。

$ rake routes

我预计最多有 1 条路线（索引页）。

Answer 1

我想还没有办法做到这一点

对于 ActiveStorage 路由，您的 config/application.rb

将具有此配置

config.active_storage.draw_routes = false

https://github.com/rails/rails/blob/c6ef71ccf23fcfb73c3cce82d8437a9bcb5bd07c/railties/test/application/configuration_test.rb#L2608, 不在当前稳定版本中，但在下一个版本的master分支中

对于 ActionMailbox 路由，我什至在 master 分支上也找不到任何东西。我想下一个版本会有类似 active_storage 配置的东西。

Answer 2

如果您不会在您的项目中使用这些功能，您应该运行

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

在那里你可以看到新的 Rails 应用程序选项的完整列表

rails new --help

顺便说一句：新 Rails 应用默认不包含任何路由。参见 Rails routing guide

Answer 3

我也刚打了这个。如果您将此代码添加到您的 config/application.rb，它将删除这些路线：

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 来访问将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中删除，并且由于它是私有 API，它可能稍后会中断，但至少它会清除 bin/rails routes.[=13= 的输出]

Answer 4

您可以通过展开您的 application.rb 文件需要 rails/all。此文件仅包含默认 rails 库。 Have a look。

通过替换此行，您不仅可以排除路由，还可以防止您的应用加载从未使用过的代码。

这是一个示例，显示了我的 application.rb 文件的顶部：

# 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 5

在 config/application.rb 中替换此行：

require "rails/all"

根据其内容，只保留您需要的枕木：

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
