extend the definition for polimorphic relationships

[pdipietro]

Hi all,
I'd need to define a polimorphic relationship.
Your suggested solution is to use

 has_many :in, :people_playing_music, model_class: Band
 has_many :out, :managed_objects, type: 'manages', model_class: false

But this is a binary solution, while I'd like to have a more fuzzy one, like

 has_many :out, :managed_objects, type: 'manages', model_class: [:Band, :Singer, :Instrument]

Do you think this could be resolved anyway?

That isn't an option right now but it seems totally reasonable.

GitHub is having some trouble showing the comparison. It might be because I accidentially made the change on master first and then reverted it and based the branch on the original commit without the revision. So probably GitHub thinks that the 589_fix branch is older than master with everything that master has. Best to just look at the commit for now (see above)

It's cause of the China DDOS, I think. I had trouble commenting to an
issue, too.

Merged to master and ready for the next release

[pdipietro]

In my Gemfile I've gem "neo4j", "~> 4.0"

Trying to define the following polimorphic relationship

has_one   :out, :belongs_to, model_class: [:Group, :Discussion]  

I got the error:

SyntaxError (/home/pdipietro/.rvm/gems/ruby-2.1.5/gems/neo4j-4.1.5/lib/neo4j/active_node/has_n.rb:189: syntax error, unexpected [, expecting tCONSTANT
...Node::Query::QueryProxy.new(::[:Group, :Discussion],
...  

How can I specify the correct Gem?

[cheerfulstoic]

This is is master which means it isn't released to rubygems. If you want you can try:

gem 'neo4j', github: 'neo4jrb/neo4j'

Otherwise, it will be part of the 5.0 release which we're currently working on
