fix test when nested jpaDerivedIdentifier is used #18067

emilpaw · 2022-03-08T22:56:33Z

when a relationship is used with the jpaDerivedIdentifier option and the
related entity also has a relationship with that option set the
updateEntityMapsIdAssociationWithNewId test fails. This
is caused by the createUpdatedEntity reusing the needed parent
entity. This can't work because a parent entity, which already has a child,
can't be used as the parent for a new entity. The reason being
jpaDerivedIdentifier enforces that parent and child share the same id,
which can't be fulfilled with a reused parent entity.
Remove the reuse of the parent entity in createUpdatedEntity when the
entity uses jpaDerivedIdentifier to fix the test.

Fixes #17906

The failing test react-gradle-mysql-es-noi18n-mapsid has nothing to do with my change. I wonder why this test hasn't failed before since I did not introduce the issue.

Either way, I'd like to add a test for the changes I made but I haven't figured out where exactly it should be placed. Could someone help me with that?

mraible · 2022-03-13T06:23:38Z

Tests pass. Is this good enough?

emilpaw · 2022-03-13T10:08:45Z

@mraible The existing tests never caught the issue this PR fixes. As a measure to avoid regressions, in my opinion, we should add one JDL integration test. I am just still not sure how to go about that.

The JDL I want to test should look something like that:

entity Animal
entity Mamal
entity Cat

relationship OneToOne {
    Mamal to Animal with jpaDerivedIdentifier
    Cat to Mamal with jpaDerivedIdentifier
}

Where should I add such a test case?

It's possible to add an MapsIdGrandChildEntity*DTO json referring to https://github.com/jhipster/generator-jhipster/blob/2aa6f6d6581f98a8edb08379b252bc20e724b212/test-integration/samples/.jhipster/MapsIdChildEntityWithoutDTO.json

and add here

generator-jhipster/test-integration/scripts/11-generate-entities.sh

Line 127 in 2aa6f6d

moveEntity MapsIdChildEntityWithoutDTO

Or add to one of customId samples:

generator-jhipster/test-integration/samples/jdl-entities/custom-id.jdl

Line 19 in 2aa6f6d

EntityUuidIdMapsId to @Id EntityUuidId

@mshima Thank you.

I added the test cases.

mshima · 2022-03-15T16:56:49Z

@emilpaw is this PR ready?

emilpaw · 2022-03-15T20:30:47Z

@mshima Yes, now that the E2E tests are working again it's ready. Thank you for the commit.

mshima

Simplify the condition.

mshima

Remove back reference, it's not there

mshima · 2022-03-15T22:40:44Z

test-integration/samples/.jhipster/MapsIdGrandchildEntityWithoutDTO.json

+      "id": true,
+      "otherEntityField": "id",
+      "otherEntityName": "mapsIdChildEntityWithDTO",
+      "otherEntityRelationshipName": "mapsIdGrandchildEntityWithDTO",


Suggested change

"otherEntityRelationshipName": "mapsIdGrandchildEntityWithDTO",

"otherEntityRelationshipName" is needed even if the relationship is unidirectional, right?

This is a bug.
otherEntityRelationshipName should exist only in bidirectional.

I squashed the commits and now it's ready to merge.

We need investigation if one-to-one works without otherEntity filtering (removes already used ids). But not really related to this PR.

For now, if otherEntityRelationshipName is set, otherEntity is not set and the relationship is id, we should throw. Filtering will not work as expected.

mshima · 2022-03-18T16:03:07Z

@emilpaw can you run prettier and add relationships back-reference for the GrandChild?

emilpaw · 2022-03-18T20:44:41Z

@mshima Done.

mshima

LGTM
