[Answered ]-How to serialize multiple types of objects in django for json conversion purpose?

Serializer is for serializing django objects, right now you have list of tuples instead, so django serializer won’t handle that.

If you want to connect this 2 lists together, you must get not only user_name from your User_obj, but also user_key (id?) for connecting it with second model. If user_key is actually an ForeignKey, you can do this:

user_project_list = projectrunlog_object.values_list('user_key__user_name','project_run_date','project_run_status')

If not, you must handle it by yourself in python.

After creating list of dicts or tuples, you don’t have to run django serializer, normal json serializer will do the job:

json.dumps(list(user_project_list))
