New to jhipster and really need help with this question (sorry for repeating) : When I create a relationship to the built in User entity, my API model that's generated in Swagger wants the entire User object to be part of the request; e.g. User related to Cars....and now the PUT request for Cars wants the entire User graph included? How should I be modeling this such the API only requires the User ID and not the entire User graph? I can not include the relationship and only include the ID field in the Cars object representing the link to User but this doesn’t like the correct way to do it….

I am not understanding something about how relationships are created... OneToOne KINDA works as expected, however, when I use ManyToMany { A{b(foo) to B{a(foo) } the generated code is not bi-directional. The TypeScript Model Objects are correct! The java looks like it should work as well. But the generated app does not have A -> B and B -> A relationships. Please see this repo https://github.com/hepaestus/testproject Here is my JDL: https://github.com/hepaestus/testproject/blob/main/testproject.jdl

@amatosg Can anyone point to a demo or test project that builds as stated the different relationship types?
@amatosg It creates the relationships but the SQL Queries are not comprehensive. You do not get the entire object and all its relationships even when you choose FetchType.EAGER
@amatosg I think there is a numerical limit the number of relationships that will work automatically.
Peter E Olsen III
@amatosg It seems like if your entities are "too complex" it breaks.
@amatosg I have tried all kinds of entity definition types and styles and I still am not getting the relationships to work as I expect them to. SO Either I am thinking about this wrong, which is entirely possible, OR It's not working as it should. OR BOTH. I am super frustrated.
Alejandro Matos
@hepaestus If you're not getting the relationship as desired, I would recommend to get the additional objects in the service layer
Peter E Olsen III
@amatosg I am not sure what you mean.
I just want it to build the way the JDL says it will be built.
Alejandro Matos
What I wanted to say is that, if the relationship is not working as desired, you could mitigate the issue querying the data in your service layer. Also, you could open an issue so the team can evaluate your case

Dumb Question: How do I update JHIPSTER to 7.1.0? I have tried sudo npm update -g generator-jhipster with and without sudo but I still get the old version from jhipster --version $ jhipster --version INFO! Using JHipster version installed locally in current project's node_modules 7.0.1
I also updated my .yo-rc.json file to the jhipsterversion 7.1.0.

Just wondering - when I am using keycloack and gateway why there is still local storage of user ? with database and services and whatever. Seems to be waste of resources to me. The same is with administration frontend - when I specify withAdminUi=false it is still generated for the frontend

Hey All,
My apologies if this is not the right place to ask this question.
We have a springboot application that uses bootstrap and Jquery for its frontend. We are looking to change the frontend application to use react.
As this application has stand-alone widgets, we wanted to take baby step approach and convert the widgets one by one to use reactJS.
Someone suggested to maybe it would be best to convert the application to use JHipster first.
Is this approach recommended?

Is it correct that I can only delete entities manually which were generated by the jdl file? Is there no automated way to remove the ones not specified in the jdl file anymore?

Alejandro Matos
that is correct, you will hace to delete entities manually. A good way to do it is deleting the domain entity and the go all the way up

Failed to start bean 'webServerStartStop'; nested exception is org.springframework.boot.web.server.WebServerException: Unable to start Netty. What might be the root cause of above error? Deployed jHipster 7 on AWS EC2 instance.
There is no automatic replication mechanism between your database and Elasticsearch, so you might have out-of-sync data. As a result, you will probably need to write some specific code to synchronize your data, for example using the Spring @Scheduled annotation, to run every evening.
This also means if your database is changed outside of your application, your search indexes will be out-of-sync. The Elasticsearch Reindexer JHipster module can help in these situations.
How can I sync data from postgress to es , please help ?
