uninitialized constant ActiveGraph::Config (NameError)

[namiwang]

I'm trying to upgrade to v10 (for neo4j 4.0 support) and got a lot of issues while setting up the project.

repro

1. create a blank new rails app
2. add gem 'activegraph', github: 'neo4jrb/activegraph', branch: 'master' in Gemfile and bundle (which is commit #e387298980351d67029274b696c4672434d1f51a)
3. add require 'active_graph/railtie' in application.rb

unexpected behavior

[klobuczek]

@namiwang I was able to bypass the issue by adding:

require 'active_graph'

to application.rb. I cannot explain the reason. It works on our rails app (5.2.3) without it. If you find out please let me know. BTW you don't need to use the activegraph gem from github source. Any significant change is immediately pushed to rubygems.org as beta version.

[namiwang]

@klobuczek Thanks for the response.

I got another error cannot load such file -- neo4j_ruby_driver, After added require 'active_garph'.

I guess it's all somehow related to the new loading mechanics introduced in rails 6.

---

update:

So I tried to add gem 'neo4j-ruby-driver', and got a new error, apparently that's unrelated to this issue though.

I get a full solution by installing this driver: https://github.com/neo4j-drivers/seabolt/releases

[jacek213]

@mhanberg any luck with solving active model error?

[mhanberg]

I may have solved it locally, but we have since re-written this service in Elixir. Sorry, wish I could offer more help 😕.

No worries, thanks the feedback :+1:

@klobuczek maybe you'd be able to help? I'm trying to migrate from 9.x to 10. I see that activemodel is locked at >= 4.0 for this gem and I'm currently running v5.1.6.

[cknoxrun]

Also chasing this problem trying to migrate. I have a Rails 6 branch in the works (same codebase), where this error doesn't occur, so I imagine it is a Rails 5.1 (possibly 5.2) issue.

Edit: Just noticed active_model/attribute_set does not exist until Rails 5.2, so I imagine that is definitely the issue. I would suggest setting the minimum Rails version for ActiveGraph at 5.2.

[nomasprime]

After spending almost two days reinstalling various versions of Ruby and Rails to try and get various Neo4J gems to work, I can state that Neo4J does not love Ruby 😆

There's still no solution for a three year old issue?

[mazaira]

Same here for Rails 7 and Ruby 3.2

[pmackay]

I would also appreciate some guidance on this issue.
