ActiveAdmin评论模型无法正常工作

我创建了一个精确跟踪Getting Started with Rails的博客。然后我按照这里的教程尝试ActiveAdmin：http://activeadmin.info/documentation.html。ActiveAdmin评论模型无法正常工作

这对邮政和标签模型（我登录和创建/添加/编辑的东西），但不是评论模型工作正常。

rails generate active_admin:resource Comment 

create app/admin/comments.rb

然后，当我尝试启动服务器我得到这个：

这是ActiveAdmin当前版本中不再是一个问题。 – superluminary 2013-05-15 12:22:13

看起来像一个bug（ActiveAdmin有它自己的内置Comment模型/类的话）：https://github.com/gregbell/active_admin/issues/64

可能的解决方法可能是内给你Comment型号不同的名称在app/admin/comments.rb：

ActiveAdmin.register Comment, :as => "PostComment" do

迪伦的回答是一个很好的开始。除了他之外，我还需要覆盖控制器资源/收集方法。

app/admin/comments.rb

ActiveAdmin.register Comment, as: 'QuestionComment' do 
    controller do 
    defaults resource_class: Comment, collection_name: 'comments', instance_name: 'comment' 
    end 
end

基本上，你只是继承覆盖资源控制器的默认值（https://github.com/josevalim/inherited_resources#overwriting-defaults）

（是的，这仍然是在2014年的问题，即使在1.0.0预发布版本，但现在看来，他们要修复它从阅读GitHub的问题）

试试这个

运行在终端

rails g active_admin:resource ActiveAdmin::Comment

添加下列行 应用/管理/ active_admin_comment.rb

ActiveAdmin.register ActiveAdmin::Comment, :as => "Comment" do 
end

该编辑配置/初始化后/ active_admin

[...] 
    config.comments_registration_name = "OldComment" 
    config.show_comments_in_menu = false 
[...]

现在你有机会定制评论在应用程序/管理/ active_admin_comment.rb 但我仍然没有找到解决方案添加：更新和：摧毁行动

在1.0.pre中它现在是config的一部分，只需取消注释'active_admin.rb'配置中的行。无需重新打开评论的定义，评论可以被禁用。 – 2014-06-06 20:26:42

我在版本1.0.0.pre中遇到了同样的问题，但幸运的是，您可以使用active_admin.rb中的配置完全禁用ActiveAdmin注释，那么您就不必像上面提到的那样别名您自己的注释模型了。

config/initializers/active_admin。RB

... 
    # == Admin Comments 
    # 
    # This allows your users to comment on any resource registered with Active Admin. 
    # 
    # You can completely disable comments: 
    config.allow_comments = false 
    #

它在文档中还列出：https://github.com/gregbell/active_admin/blob/master/docs/1-general-configuration.md#comments
