ActiveAdmin Comment model not working properly

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 inapp/admin/active_admin_comment.rb

ActiveAdmin.register ActiveAdmin::Comment, :as => "Comment" doend

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.rbbut 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
