我正在尝试使用 rails generate 命令生成评论控制器，但它给出了一个奇怪的错误：-

$ rails generate controller comments
The name 'CommentsController' is either already used in your application or reserved by Ruby on Rails. Please choose an alternative and run this generator again.

我已经检查过了，但我没有评论控制器。这些是我尝试过的命令：-

$ rails generate controller Comments create
The name 'CommentsController' is either already used in your application or reserved by Ruby on Rails. Please choose an alternative and run this generator again.

$ rails generate controller comments
The name 'CommentsController' is either already used in your application or reserved by Ruby on Rails. Please choose an alternative and run this generator again.

$ rails g controller Comments
The name 'CommentsController' is either already used in your application or reserved by Ruby on Rails. Please choose an alternative and run this generator again

请帮帮我。

这是 GemFile：-

source 'http://rubygems.org'

gem 'rails', '3.2.13'
gem 'bootstrap-sass', '2.1'

# Bundle edge Rails instead:
# gem 'rails', :git => 'git://github.com/rails/rails.git'

gem 'sqlite3'
gem 'mysql'
gem 'activeadmin'
gem "meta_search",    '>= 1.1.0.pre'
gem 'formtastic'


# Gems used only for assets and not required
# in production environments by default.
group :assets do
  gem 'sass-rails',   '~> 3.2.3'
  gem 'coffee-rails', '~> 3.2.1'

  # See https://github.com/sstephenson/execjs#readme for more supported runtimes
  # gem 'therubyracer', :platforms => :ruby

  gem 'uglifier', '>= 1.0.3'
end

gem 'jquery-rails'
group :development, :test do
  gem 'rspec-rails', '~> 2.11.0'
  gem 'factory_girl_rails', '~> 3.5.0'
  gem 'capybara', '~> 1.1.2'
  gem 'guard-rspec', '~> 1.2.0'
end

# To use ActiveModel has_secure_password
gem 'bcrypt-ruby', '~> 3.0.0'

# To use Jbuilder templates for JSON
# gem 'jbuilder'

# Use unicorn as the app server
# gem 'unicorn'

# Deploy with Capistrano
# gem 'capistrano'

# To use debugger
# gem 'debugger'

active_admingem 使用相同的名称comments。这就是为什么 rails generator 不让你创建comments controller. 请参阅：github.com/gregbell/active_admin/tree/master/lib/active_admin。在这里你可以看到comments目录。因此，最好为您的控制器使用其他名称以避免出现问题。

如果您不需要管理部分中的评论，则可以将其关闭。

去/config/initializers/active_admin.rb写config.allow_comments = false。完成此操作后，您可以生成控制器，并且不会与 active_admin 冲突。

您可以阅读活动管理文档以获取更多信息。

我刚刚comments_controller手动创建了它，它正在工作。active_admin可能是个问题。我问了一个朋友，但他没有遇到任何这样的问题active_admin。所以，我不确定问题是什么，但现在，手动创建控制器是可行的。
