[-]Elasticsearch Denormlizer returns null for fields composed of two ore more words (ex. firstName)[/-][+]Elasticsearch Denormalizer returns null for fields composed of two ore more words (ex. firstName)[/+]on Feb 11, 2021 I think we definitely have a problem with documents with fields in snake case (cf. api-platform/docs#1204 (comment)). I will investigate this in the next few weeks.
Thanks a lot. I'll be waiting
@imaximius i can confirm issue comes from getAllowedAttributes comparison (snakeCase in ES vs CameCasel in models)
@meyerbaptiste got ideas to solve this ?Regards
This has been resolved:
InnerFieldsNameConverter(src/Elasticsearch/Serializer/NameConverter/InnerFieldsNameConverter.php) now converts snake_case ES fields back to camelCase during denormalization, andtests/Functional/Elasticsearch/ReadTest.phpcovers multi-word fields likefirstName/lastName. Verified on current4.3HEAD. Closing as fixed — please reopen if you still reproduce on a recent release.My previous comment was wrong, sorry: nothing converts snake_case fields by default, the
InnerFieldsNameConverterfallback never applies and the functional tests use camelCase fields. See #8470.To map snake_case documents you need to configure a name converter, the docs are updated in api-platform/docs#2349. Note that the converter also applies to the field names used by filters and sorting.
API Platform version(s) affected: 2.6.3
Description
As mentioned in summary there is an issue with getting data form Elasticsearch. It reproduced when I tried to get data for fields that composed of several words (ex. firstName, createdAt etc.) Result the same for jsonld and graphql normalizers and for nested objects as well.
How to reproduce
Possible Solution
There is could be a bug with comparing allowedAttributes to attributes from ES result. Method getAllowedAttributes of AbstractObjectNormalizer returns allowed attributes in camel case whereas attributes in ES source wrote in snake_case
