Answer 1

I'm using Django 3.1.4 and here is my solution.

I have a model Qualification

model.py

from django.db import models

TRUE_FALSE_CHOICES = (
    (1, 'Yes'),
    (0, 'No')
)


class Qualification(models.Model):
    qual_key = models.CharField(unique=True, max_length=20)
    qual_desc = models.CharField(max_length=255)
    is_active = models.IntegerField(choices=TRUE_FALSE_CHOICES)
    created_at = models.DateTimeField()
    created_by = models.CharField(max_length=255)
    updated_at = models.DateTimeField()
    updated_by = models.CharField(max_length=255)

    class Meta:
        managed = False
        db_table = 'qualification'

admin.py

from django.contrib import admin
from models import Qualification


@admin.register(Qualification)
class QualificationAdmin(admin.ModelAdmin):
    list_display = [field.name for field in Qualification._meta.fields if field.name not in ('id', 'qual_key', 'qual_desc')]
    list_display.insert(0, '__str__')

here i am showing all fields in list_display excluding 'id', 'qual_key', 'qual_desc' and inserting '__str__' at the beginning.

This answer is helpful when you have large number of modal fields, though i suggest write all fields one by one for better functionality.
