NoMethodError in Admin::Users#index undefined method `associations' for User:Class

[grzegorz-jakubiak]

This is what I get when I click on Users link in ActiveAdmin. I use model generated by activeadmin:install command I've only changed the name from AdminUser to User and all of the methods accordingly and I don't have any associations. I just want to see the users page before I start building my models.

The actual error:

NoMethodError in Admin::Users#index

Showing /home/gregg/.rvm/gems/ruby-2.4.2@hms-mongoid/gems/activeadmin-1.1.0/app/views/active_admin/resource/index.html.arb where line #2 raised:

undefined method `associations' for User:Class

My configuration:

Rails 5.0.6
mongoid 6.0.3
activeadmin-mongoid 0.4.0

I've installed kaminari-mongoid on my own.

I'm providing stack trace as well:

@greggzst can you please provide the contents of your Gemfile.lock and confirm that you've modified your application.rb file as specified here: Remove Application Dependencies

Here is everything you wanted. I'm surprised because I created TestModel class without any fields and I can see this panel in activeadmin without any errors as opposed to Users page.

@greggzst I suspect it has to do with Rails 5.1.x instead of Rails 5.0.x, if you're able, try downgrade to Rails 5.0 and see if it goes away. I tried moving to 5.1 on an app we have here and got some funky errors. We'll have to work on an upgrade to support Rails 5.1.x

[grzegorz-jakubiak]

@boie0025 Unfortunately it doesn't. I tried different Rails(5.0.0 and 5.0.3) and Rubies(2.2.0, 2.3.1, 2.4.0 and 2.4.2) and always ended up having this error when I try to see users panel.

[boie0025]

@greggzst Well, there goes that theory. We've also had some issues with Kaminari versions, give this a try:

gem 'kaminari-mongoid', '= 0.1.2'
gem 'kaminari', '= 0.17.0' 

In the meanwhile, I'm going to create a new rails app with your gemfile and see if I can re-create the error.

[grzegorz-jakubiak]

@boie0025 This change doesn't help either. I still get the same error.

[boie0025]

@greggzst - OK I'm out of ideas now. If you create a repo with all of the relevant parts of your current app that re-creates the error I can dig, otherwise, you should be able to work around this by turning filters off in ActiveAdmin config: config.filters = true and/or config.include_default_association_filters = true

[boie0025]

@greggzst Actually, try remove the "created_at" filter from your default User model..
Remove filter :created_at

[grzegorz-jakubiak]

@boie0025 Removing filter :created_at helps I can see users now. So it's the mentioned issue with filters I suppose? Do you still want me to upload my repository?

[boie0025]

@greggzst Yes, it took me a while to connect the dots. No, I have replicated the issue myself (and that's how I found the filter issue). Thanks!

[jonatasdaniel]

I'm still having this issue and I don't even have filter on my admin. Any news on this? I'm using both ActiveRecord and MongoId.
