Re: Update dict JsonField Postgresql

json.dumps return this (For example, the field contains 50k of records):

[{'number': '1160188479', 'id': 0, 'content': 'hello', 'processed': False}, {'number': '1160188479', 'id': 1, 'content': 'hello', 'processed': False}, {'number': '1160188479', 'id': 2,'content': 'hello', 'processed': False}, {'number': '1162341721', 'id': 3, 'content': 'hello', 'processed': False}, {'number': '1162341721', 'id': 4, 'content': 'hello', 'processed':False}, {'number': '1162341721', 'id': 5, 'content': 'hello', 'processed': False}]

Is this really how you typed it? Because objectitem.data[0] should be a dict or list, but not a boolean.

Could you show the output of:

 

json.dumps(objectitem.data)

I'm not sure it is used for assigning data to the json field. It is used to form a django.http.JSONResponse and to serialize data to JSON, so that was a guess.

Not sure, but as you typed it, it's a set, not a dict (there is no 'key':), so if python thinks any of the lists are identifcal, it'll be missing.
