I'm trying to create procedure for a cypher script with apoc.custom.declareProcedure (same for the asProcedure pendant) and always receive the exception: Failed to invoke procedure `apoc.custom.declareProcedure`: Caused by: java.lang.RuntimeException...

Hi community, we need to link a bunch of nodes connected in one way with arbitrarily deep paths to a :Module node using :includes relations. Therefore we're using patterns like: match path=(:System:Workflow:Application)-[:raises]->(:System:Workflow:E...

Hi community, I'm running some cypher statements with apoc functions inside my Java plugin. Problem is, that the tests fail saying apoc functions are unknown. How can I include apoc to my project? Is there public lib I can import from? Kind regards, ...

Hi folks, I'm new to neo4j plugin development as until today I came through every task with cypher and apoc for the last nine years. Anyway - right now I've got stuck mapping a response from neo4j within Java an iternate through the nested lists. My...

User management with multi tenant setup · 08-05-2020

Hi community, we're trying to move our application from a graph-based user management over to the integrated role based one from the 4.1 enterprise. At the moment we have all users stored in one instance per tenant and therefore the management is sec...

Thanks Michael, we finally came up using a bunch of queries describing all possible paths.

To make it a bit clearer I've taken a screenshot from the first few levels of one of our applications. As you can see the :Application node (top left) already has it's own :Event (purple-colored) and :Element(dark-grey colored) nodes. The main probl...

The paths are already there and we want to link each node of those paths to one :Module node. The main problem is, that we can't match all of the relevant nodes as described above. Hope this additional information helps.

florent.biville1: Neo4jContainer Hi Florent, it's primarly for testing using the APOC Cypher API. I've got the following class describing my test. package SDM.BOM; import org.junit.*; import org.neo4j.driver.v1.*; import org.neo4j.harness.jun...

Hi Michael, I just put some efforts into it. I can iterate through all nested objects thanks to your hints using a for loop on a result map. Though I can't use any apoc functions inside the queries running the tests of the project. But I'll close thi...
