ActiveAdmin Comment model not working properly

I created a blog by following the Getting Started with Rails precisely. And then I following the tutorial here to try ActiveAdmin: http://activeadmin.info/documentation.html.

It's working fine for the Post and Tag models (I logged in and created/add/edited stuff) but not the Comment model.

rails generate active_admin:resource Comment

create  app/admin/comments.rb

Then when I try to start the server I get this:

rails server=> Booting WEBrick
=> Rails 3.0.7 application starting in development on http://0.0.0.0:3000
=> Call with -d to detach
=> Ctrl-C to shutdown server Exiting /usr/local/lib/ruby/gems/1.9.1/gems/activeadmin-0.2.2/lib/active_admin/namespace.rb:116:in

Look like a bug (ActiveAdmin has it's own built-in Comment model/class already): https://github.com/gregbell/active_admin/issues/64

A possible workaround could be to give your Comment model a different name within in app/admin/comments.rb:

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

try this

run in terminal

rails g active_admin:resource ActiveAdmin::Comment

add a following lines in app/admin/active_admin_comment.rb

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

after that edit config/initializers/active_admin

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

And now you have opportunity to customize a comments in app/admin/active_admin_comment.rb but i still didn't find solution to add :update and :destroy actions

I had the same problem with version 1.0.0.pre, but thankfully, you can suppress ActiveAdmin comments altogether with a config in active_admin.rb then you don't have to alias your own Comment model anymore as mentioned above.

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
  #

It's also listed in the docs: https://github.com/gregbell/active_admin/blob/master/docs/1-general-configuration.md#comments
