activeadmin: undefined method `total_count' for #
We upgraded to Rails 5.1.4 and ActiveAdmin 1.1.0 and now an active_admin show page raises this exception. In my active-admin model file, I can comment out the line active_admin_comments
and it works fine so I suspect the problem is in there. In the screenshot there is unfortunately no stack trace other than my model .rb file.
Expected behavior
No exception should be raised.
Actual behavior
Showing …/.rbenv/versions/2.3.1/lib/ruby/gems/2.3.0/gems/activeadmin-1.1.0/app/views/active_admin/resource/show.html.arb where line #2 raised:
undefined method `total_count’ for #<ActiveRecord::Relation []>
How to reproduce
I make the simplest active-admin model file like so, and it crashes:
ActiveAdmin.register ClinicSource do
show do
active_admin_comments
end
end

I am a little late here, but for those who keep getting the same error, here is another solution:
@ghilead
Try adding an initializer as below:
/config/initializers/will_paginate.rb
I hope this will fix the issue.
@AaronGaim Are you also using
will_paginate
? If you are, have you tried the fix mentioned here?@winstonwolff @ghilead as for the issues you’re having. I think they’ll be resolved by monkey patching
will_paginate
to respond to the kaminari interface that AA expects, however I think we should close this issue (since it’s not actually a bug with AA).If one of you wants to open a discussion-based issue around adding the features from
will_paginate
that you’re using into AA (or other similar feature requests), feel free to do so. For now though @varyonic I think this issue should be closed.@winstonwolff Thanks for the report. I think we’ll need more information though. Using the environment you described (RoR 5.1.4 and AA 1.1.0) I made a sample app with a show page exactly like what you said should reproduce the problem:
and I don’t get any errors:
Can you include the source for the
ClincSource
model as well as your Gemfile?Hi Will—
I found this with a suspicious comment. I’ll investigate this on Monday.
Thank you for your time investigating this. Hopefully I can figure out the conflict.
