How to dynamically select variable data columns from variable tables when the columns and the tables are dependent on stored data?

Using Django 1.10, Python 3.5,

I have stored various information about the columns and tables I want to use to extract data in another table called smart_view

That smart_view has the following columns:

1. id (auto increment)
2. name (varchar 255)
3. columns (jsonb type)
4. tables (jsonb type)
5. conditions (jsonb type)

I want to dynamically select data columns from tables that may vary depending on the data stored in smart_view table

I read about dynamically generate filters using an answer from https://stackoverflow.com/a/4720109/80353.

Is that applicable to my situation and how do I do the same for the tables (or Model) part?

UPDATE

The usual way of selecting specific values is

Entry.objects.values_list('id', 'headline')

As seen in https://docs.djangoproject.com/en/1.11/ref/models/querysets/#values-list

By dynamic, I meant you wouldn't know beforehand which model to extract the values from and which values they might be because they are stored as data in the table called smart_view
