unitialized constant [Class]::Votable?

[grimmwerks]

Hey there - followed the directions, did the migrate, etc, added 'acts_as_votable' to my class (Episode) and am getting this in active admin:

Does this only exist in active admin? Can you paste the relevant files or create a failing test case?

[grimmwerks]

I can put together an example - honestly it was just me adding the acts_as_votable to a very thin model:

class Episode < ActiveRecord::Base
    acts_as_votable

    belongs_to :show
    has_one :creator, :through => :show
    has_and_belongs_to_many :categories, :join_table => :categories_episodes

end

There's also this discussion: activeadmin/activeadmin#2378

Thanks for the link. I think I've fixed this. Can you try installing version 0.7.1 of the gem and let me know if it works?

gem "acts_as_votable", "~> 0.7.1"

Then run bundle update acts_as_votable and restart your rails app.

Let me know if this fixes it. Thanks for reporting the issue.

That seems to have done it, thanks for the quick fix!
