References are not handled properly in Querydsl integration. [DATAMONGO-972]

[spring-projects-issues]

Timo Westkämper opened DATAMONGO-972 and commented

References are not handled properly in the Querydsl integration of Spring Data Mongodb. MongodbSerializer provides too related template methods which should be overridden in SpringDataMongodbSerializer.

The Querydsl Mongodb integration with the Morphia mapping framework shows how it can be done https://github.com/querydsl/querydsl/blob/master/querydsl-mongodb/src/main/java/com/mysema/query/mongodb/morphia/MorphiaSerializer.java

Thank you Timo Westkämper for pointing to this. Though it seems that isReference is not called in 3.4.0 and would require an update to 3.4.1, which showed some glitches (see: spring-data-build#90)

According to the Querydsl issue tracker, 3.4.2 is scheduled for July, 31st which is both after our schedule M1 for Evans and Codd SR2. We could of course add the fixes to the code base but ignore the test cases for now which seems a bit suboptimal. On the other hand, I'd love to get this fix out ASAP.

Timo Westkämper If there's any chance you can do the 3.4.2 release earlier, please let me know

I've applied the pull request to the master and bugfix branches. Ignore the test case for now. I'll close this as resolved and open a ticket to remove the @Ignore once we upgrade to 3.4.2

This feature has already been available in Querydsl 3.3.0 https://github.com/querydsl/querydsl/blob/QUERYDSL_3_3_0/querydsl-mongodb/src/main/java/com/mysema/query/mongodb/morphia/MorphiaSerializer.java

An earlier release date for 3.4.2 should not be necessary

The test is failing when run against a Querydsl version < 3.4.1. It works on 3.4.1, though. The relevant methods don't seem to be called in versions prior to 3.4.1

Sorry, you are right. There was a related fix in 3.4.1 querydsl/querydsl#803.

What would be a suitable release date for you?

Oliver Drotbohm commented

The milestone is scheduled for tomorrow but I'd understand that that's a bit of a rush. I have merged the fix already, so it's just the test case that needs to be reactivated. If you can sneak it in earlier than end of June, fine. If not, then that's it, no big deal :)

Ok, I will try something earlier, I will be working again beginning from 21.7. I will try to make the release that week
