I'm migrating a kotlin spring data neo4j application from spring-data-neo4j version 5.2.0.RELEASE to version 6.0.11.
The original application has several Repository interfaces with custom queries which take some DTO as a parameter, and use the various DTO fields to construct the query. All those types of queries currently fail with

QUESTION
I have a graph with two types of nodes: Persons and Houses. In this graph, persons can sell houses (SELLS relationship), and houses are bought by persons (IS_BOUGHT_BY relationship). This could be represented as the following diagram:
ANSWER
Answered 2022-Mar-14 at 14:37Currently, Gremlin, outside of perhaps using in-line code (closure/lambda), has no way to inject virtual edges into a query result. This might be a good feature request to open as a Jira ticket for Apache Tinkerpop at this location.
As a short term solution, I think the best you can do is to create the edges for the needs of a visualization and perhaps give them a unique property key and value something like "virtual":true and to delete such edges when no longer needed.

QUESTION
Is it possible to connect to AuraDB with neomodel?
AuraDB connection URI is like neo4j+s://xxxx.databases.neo4j.io.
This is not contained user/password information.
However, connection config of neomodel is bolt and it is contained user/password information.
config.DATABASE_URL = 'bolt://neo4j:password@localhost:7687'
ANSWER
Answered 2022-Mar-01 at 16:13Connecting to neo4j Aura uses neo4j+s protocol so you need to use the provided uri by Aura.
Reference: https://neo4j.com/developer/python/#driver-configuration
In example below; you can set the database url by setting the userid and password along with the uri. It works for me so it should also work for you.

I need to create a custom directive on INPUT_FIELD_DEFINITION to check if the provided value of the enum isn't being changed to the previous "state" (business logic is that states must go UNAPPROVED - > APPROVED -> CANCELLED -> FULFILLED) but can't quite figure out how to map values in constructor of the enum type.

QUESTION
ANSWER
Answered 2021-Dec-13 at 14:07Is seems that log4j version 1.2.17 is used in neo4j 3.5.21 and this version is not vulnerable to https://nvd.nist.gov/vuln/detail/CVE-2021-44228 as the vulnerability was introduced with version 2.10.0.
In any way log4j version 1.2.17 is vulnerable to https://nvd.nist.gov/vuln/detail/CVE-2019-17571 which has a score of 9.8 out of 10. It is a different attack vector maybe harder to exploit, but same as critical and should not be used in production.
You should update your neo4j version in any way.
QUESTION
I have a Neo4j database where i have ingredient nodes and recipe nodes. One recipe is connected to many nodes, so, for a simple cheddar sandwich, the recipe node would be connected to bread and cheddar cheese. What i wanted to achieve is to query all the recipes that contain for example at least pepper and salt so if my recipe has pepper, salt and ham it would match. What i have tried following this example is:
...ANSWER
Answered 2021-Dec-12 at 18:58This looks like a very awkward way of doing this.
Most people would use a relational database and SQL.
The database would have a table that stores the relation "ingredient is used in recipe" which connects the ingredient ID to the recipe ID.
