HABTM relation causes NameError - uninitialized constant Model1::HabtmModel2

[Meekohi]

class Artist < ActiveRecord::Base
    has_and_belongs_to_many :events
end
class Event < ActiveRecord::Base
    has_and_belongs_to_many :artists
end

when I visit /admin I get the error
NameError - uninitialized constant Artist::HabtmEvents:
stack trace: https://gist.github.com/Meekohi/199d798b109a8a5212fe

Although using them on the rails console seems to work fine.

You can whitelist the models that appear as described here:

Thanks Jonathan. Michael this looks like this is related #112 (or at least @ernsheong's issue). Let me know if setting config.models works for you, and I"ll close this one and track the issue there.

[Meekohi]

Yup I can confirm this works config/initializers/upmin_admin.rb:

Upmin.configure do |config|
  config.models = [:user, :event, :artist]
end

Looking at this again, I think @ernsheong's and your issue is different to the one @mfa123 originally reported at #112, so I think it deserves its own issue.

I am also having this problem. Coincidently the HABTM models in question are precisely the models that require much hands on administration. I hope this issue can be resolved because I am otherwise very excited about this project!

Hey @cassidyclawson, so the good news is there's already a PR in for this with #126 :) but it might be a little while before this make is into the codebase and a released version of the gem. However there's an easy workaround by configuring which models to display: https://github.com/upmin/upmin-admin-ruby/wiki/Configurations as @ernsheong mentioned. Let me know how you get on!
