In your config/application.rb = ENV || 'neo4j://localhost:7687'Ĭ.

They will be used in the background in this case. See the documentation for more info.Īlso note that with the query chaining there is no need to use params (which are important for efficient neo4j queries). There is also a query-building API which allows you to build cypher queries with method chaining: user = ActiveGraph::(found: :User)Īt each step in the chain a query object is returned which is also Enumerable. Leverage Knowledge Graphs and Generative AI by integrating Neo4j with Large Language Models (LLMs) to create intelligent applications. Me = ActiveGraph::Base.query('MATCH (found:User) WHERE found.name = RETURN found', aName: 'Andreas').first.found Neo4j::Driver::GraphDatabase.driver('neo4j::/localhost:7687') If you just want to execute some raw cypher queries you can do the following.
