How can I get rid of this error in active admin rails app NoMethodError in Admin::Records#show?

Question

I have installed active admin gem to my rails app. I integrated with my models well. After I login to admin panel and want to view my records it shows this error. This error comes in updating and submitting the button. But internally the file is updated and edited, there is no side effect of this.

I have integrated my records with will paginate.

I have added this file to my /config/initializers/kaminari.rb too but couldnot solved...

Kaminari.configure do |config|
  config.page_method_name = :per_page_kaminari
end

The complete error is:

undefined method `total_count' for #<ActiveRecord::Relation []>
Did you mean?  total_entries

125      end
126    end
127  end

Answer 1

I have disabled the active admin comments. Previously, comments were enabled by default in the file /config/initializers/active_admin.rb

# You can completely disable comments:
# config.comments = false

I disabled the active admin comments by changing the code:

# You can completely disable comments:
config.comments = false

And finally get rid of that error. Thank you all.
