Validate schema extractor syntax about horreum

[rvansa]

@JacksonIsaac As I've said above, a separate REST endpoint in SchemaService that would run SELECT jsonb_path_query_first('{}', path) and see if that throws any error, and report that back to Horreum.

On the UI side that would be Schema.tsx where you'd fire the request 1 second after jsonpath change.

I think that the best first step would definitely be getting Horreum running locally to see the UI for yourselves. If you're using podman instead of docker, I've just created a compatible definition for that as well - please see README.

Working on this :)

I am currently looking at SchemaService.java#L274. Is this the correct place to add this check ? I am still trying to figure out how this syntax validation will be done.

I also assume that the check has to be done on extractor variable (line 316) ?

Hi @JacksonIsaac , that was quick :) Are you already using Horreum?

Actually I had in mind a separate endpoint, checking the query as I type (with minor delay, e.g. 1 second, to prevent bombarding the server with every letter).

[JacksonIsaac]

I haven't used Horreum, but just tried to read the code to understand what's going on. So let me know what you had in mind, and I'll follow up from there.

@JacksonIsaac Hi, any progress? Have you managed to set up Horreum or do you have any issues?

[JacksonIsaac]

Hi @rvansa, I was able to setup Horreum and access the UI. I was looking at adding a @post api in SchemaService (called maybe validate_schema), but I wasn't sure how the sql query would execute from there

[rvansa]

@JacksonIsaac SchemaService has injected EntityManager em and AgroalDataSource dataSource fields; You can either run a native query through the former one or use JDBC directly on the latter. Since the query does not access any data nor modifies anything you do not need to wrap it with

try (CloseMe h = sqlService.withRoles(em, identity)) { ... }

as other DB calls in the class do.
