Comment (by john-parton):
Coming back to this briefly.
The discussion was not particularly productive, but a specific use case of
generating bits of Elasticsearch documents or queries was mentioned:
https://forum.djangoproject.com/t/ability-to-specify-keys-for-jsonobject-
using-arbitrary-expressions/38559/4
The elasticsearch query language is a subset of JSON where the specific
field is represented as a key in a json object. Documentation:
https://www.elastic.co/docs/explore-analyze/query-
filter/languages/querydsl#query-filter-context-ex
If you have an EAV table and want to directly generate JSON documents
where the keys correspond to the entities in your table, you cannot do
that with the current JSONObject implementation. I give some reasoning
here: https://forum.djangoproject.com/t/ability-to-specify-keys-for-
jsonobject-using-arbitrary-expressions/38559/3
(I personally don't like EAV tables and would suggest storing extended
attribute directly as json documents on rows, but you might have a legacy
table design that prevents you from doing that.)
We can keep this wontfix, just wanted to come back and summarize, although
I am interested in SImon's opinion. (Not sure how to summon him. A
particular favorite food perhaps?)
