Fetch Json Field value using Values in Django

I have a JSON field in my model and by using values option, I would like to get the key value present in the JSON field.

Assume my JSON field value is:

{"key1":"value1","key2":"value2"}


MyClass.objects.values("field1","field2","JSON Key")

Let JSON Key be "Key1"

Expected O/P:

 [{field1:Value1,field2:value2,Key1:value1}]
