find_scope! fails when comparing if user.is_a?(User)

[andrewhavens]

I'm running a Rails 4.2 application, using the latest version of devise (3.5.1), latest version of devise-neo4j (2.0.0), and latest version of neo4j (5.0.2). As explained in neo4jrb/devise-activegraph#16, I am unable to call sign_in user because Devise.ref.name does not return User. Instead, it returns something that looks like this:

User(authentication_token: Object, confirmation_sent_at: DateTime, confirmation_token: Object, confirmed_at: DateTime, created_at: DateTime, current_sign_in_at: DateTime, current_sign_in_ip: Object, email: Object, encrypted_password: Object, facebook_token: Object, first_name: Object, last_name: Object, last_sign_in_at: DateTime, last_sign_in_ip: Object, remember_created_at: DateTime, reset_password_sent_at: DateTime, reset_password_token: Object, sign_in_count: Object, tos: Object, unconfirmed_email: Object, updated_at: DateTime)

It seems this has something to do with class caching. But I don't really understand how this works. So I'm having trouble trying to find a solution (or even identify how it is supposed to work). These lines seem to be the source of my issues:

ActiveSupport::Dependencies::reference(User)
ActiveSupport::Dependencies.constantize(User)

It's possible that this is a bug with the neo4j gem. However, if you know how this ActiveSupport::Dependencies::reference stuff is supposed to work and what I need to do to fix it, that would help.

Otherwise, as a workaround, if you could help me find a way of signing in a user and avoid those lines of code that are failing, that would be helpful too.

I'm really just trying to figure out how to move forward.

Thanks!

You need to give us a way to reproduce the issue, otherwise there isn't much we can do.
