As could not find any reviewer, I am good to have this r+

@safwanrahman does it work for you out of the box now?
I still am getting a list of empty dicts (with the psql-db-value being {"2": "sadf", "foo": "baaar"}):

"negotiation_status": [
  {}
  {}
],

Only when I do:

    def prepare_negotiation_status(self, instance):
        return instance.negotiation_status

I get:

"negotiation_status": {
  "2": "sadf",
  "foo": "baaar"
},

@andreasnuesslein Oops, Sorry. I expected to have it working normally. I need to fix it before releasing new version. Are you using master branch? It is high likely that there is error code.

[andreasnuesslein]

@safwanrahman Yeah I tried it with master but the same thing happens with the current stable pip release 7.1.0 , after setting negotiation_status = fields.ObjectField().

mentioning #36 here for bidirectional link

So I dove into the code and figured out you should just replace ObjectField with DEDField.

@andreasnuesslein I'm having a similar issue. Where did you replace ObjectField with DEDField?

[andreasnuesslein]

hey @oehrlein , I think it was somewhere here: https://github.com/django-es/django-elasticsearch-dsl/blob/master/django_elasticsearch_dsl/documents.py#L27

but since then the code has been changed a bit it seems - sorry 🤷 I'm not involved in this anymore; @safwanrahman will probably know an answer.

[oehrlein]

@andreasnuesslein Got it, no problem! I was just curious since I was working on (and found) a solution to the "list of empty dicts" issue you had above.
