Description (last modified by nitishxp)

Hi,

I encountered a bug in raw postgresql query 

from django.db.models import JSONField
from django.db import connection

class Job(models.Model): 
    job_dict = JsonField()


def view(request):
       with connection.cursor() as cursor: 
            cursor.execute("select job_dict from app.job", ())
            column_names = [desc[0] for desc in cursor.description]
            results = [dict(zip(column_names, row)) for row in cursor.fetchall()]

The given result will have the job_dict column as string instead of dictionary

Replying to Mariusz Felisiak:

Can you give me the example how to call json.loads() on fetched data in case of cursor query. I am having hard time figuring this out.

Thanks
