Question

我正在尝试使用rails generate命令生成注释控制器，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.

我已经查过，但我没有评论控制器。这些是我尝试的命令： -

$ 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

Plz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'

Answer 1

active_admin gem使用相同的名称comments。这就是rails生成器不允许您创建comments controller的原因。请参阅：github.com/gregbell/active_admin/tree/master/lib/active_admin。在这里，您可以看到comments目录。因此，最好为控制器使用其他名称以避免出现问题。

Answer 2

如果您不需要管理部分中的评论，则可以将其关闭。

转到/config/initializers/active_admin.rb并撰写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active admin documentation了解详情。

Answer 3

我刚刚手动创建了comments_controller，它正在运行。 active_admin可能是一个问题。我问了一位朋友，但他没有遇到active_admin的任何问题。所以，我不确定问题是什么，但现在，手动创建控制器。
