undefined method `paginate' despite 'neo4j-will_paginate_redux' is required

[im-13]

Could you please explain why I get undefined method `paginate' error? The gem is required in the rb file:

require 'neo4j-will_paginate_redux' class MatchesController < ApplicationController def create [some code] @matches = User.query_as(:n).match("n-[:lives_in]->(country:Country)").where("country.name = '#{target_country.name}' AND n.email <> '#{username}'").pluck(:n).paginate(:page => params[:page], :per_page => 10, order: :first_name) [some code]

Two issues:

As soon as you call pluck, you return records from the database and are working with an enumerable. not any kind of query object, so pagination isn't possible.

Second, paginate is a method on the QueryProxy class but as soon as you call query_as, you are working in Neo4j-core's Query class, which powers QueryProxy. There's an article about the classes at http://neo4jrb.io/blog/2015/02/08/query_or_query-proxy.html.

@subvertallchris Any chance we might see this extended to work for a general Query? My query has passed beyond the ability of QueryProxy's mighty lil' query builder...

We could rework this gem and the Paginated class. Paginated mostly uses methods that are from or available in Neo4j::Core::Query, so we could refactor it to provide interfaces in both that class and QueryProxy. I'd probably need a hand with it, though. A little short on time at the moment.

@subvertallchris ...and I just discovered proxy_as... I'll probably just use that to transform my result back into a QueryProxy and then call .paginate from there. That seems like it would work to me.
