howto use neojrb together with active record

[fap2...@gmail.com]

So I installed neoj4rb with the following approach. I can create neo4j classes with scaffold. So here come my rookie question:

what are my approach to create active records objects with scaffold? So is there some way I can differentiate between creating activerecords and neo4j classes with scaffolding?

Yes, I'm still a novice. So bare with me.

1. I manually inserted "gem 'neo4j', '3.0.0.rc.3'" into my gemfile and ran the bundle command.

2. I manually inserted  "require 'neo4j/tasks/neo4j_server'" into the RakeFile, that is already made when I created the application:

   require File.expand_path('../config/application', __FILE__)
require 'neo4j/tasks/neo4j_server'

Rails.application.load_tasks

3. Manually added into the application.rb the following lines in bold:

   require 'neo4j/railtie'

module GraphNeo4j
  class Application < Rails::Application

    config.generators do |g|
      g.orm             :neo4j
    end
   
    config.neo4j.session_type = :server_db
    config.neo4j.session_path = 'http://localhost:7474'
  end
end

4. I used 'rake neo4j:install[enterprise-2.1.5]' and it worked fine by installing the neo4j directory.

5. Created a new comment class. Started up the application

6. I started the neo4j server. Created a new Commend and saw it in the web server browser. It seems to work.

Awesome! Remove the ".rc.3" part from the gemfile. You just want "gem 'neo4j'". Do "bundle update neo4j" when you're done.

I'm not so sure how you can do scaffolds for ActiveRecord once Neo4j is setup. I try not to use scaffolds. ;-) You can create Neo4j models so easily, I don't really find scaffolds super helpful. They are helpful for ActiveRecord, since writing migrations is a pain in the ass.

Thx. I just use scaffold in the begining of my application. I can see that it is invoking neo4j, so maybe I can change that someplace to active record?

rails g scaffold comment body                                                            
      invoke  neo4j
      create    app/models/comment.rb
      invoke    rspec
      create      spec/models/comment_spec.rb
      invoke  resource_route
       route    resources :comments
      invoke  scaffold_controller
      create    app/controllers/comments_controller.rb
      invoke    erb

There's a github issue about it, it's still open. I'm on my phone so I can't link you but check for it, it's recent.
