Early on in the development of my Django project, I had to rebuild the database a thousand times! To make my life easier, I created Django Management Commands to recreate data from these Management Commands. As you can imagine, to recreate all my models like: a DoriDoro instance and several instances of Achievements, Degree, Fact, Hobby, Job, Language, Reference and SocialMedia.

Here is an example of a Management Command:

# doridoro/management/commands/create_links.py

from django.core.management.base import BaseCommand
from django.db import IntegrityError, transaction

from projects.models import Link

class Command(BaseCommand):
    help = "This command creates all Job instances for DoriDoro."

    def handle(self, *args, **options):
        try:
            links = [
                {
                    "title": "Epic Events",
                    "legend": "Project 12 of OpenClassrooms Python Path",
                    "origin": Link.GITHUB,
                    "platform": Link.OPENCLASSROOMS,
                    "url": "https://github.com/DoriDoro/EpicEvents",
                },
                {
                    "title": "Orange Country Lettings",
                    "legend": "Project 13 of OpenClassrooms Python Path",
                    "origin": Link.GITHUB,
                    "platform": Link.OPENCLASSROOMS,
                    "url": "https://github.com/DoriDoro/OC_lettings",
                },
                {
                    "title": "Django Portfolio",
                    "legend": "Django Portfolio",
                    "origin": Link.GITHUB,
                    "platform": Link.PERSONAL_PROJECT,
                    "url": "https://github.com/DoriDoro/django_portfolio",
                },
            ]
            if Link.objects.exists():
                self.stdout.write(
                    self.style.WARNING("These instances of Link exists already!")
                )
                return
            with transaction.atomic():
                for link in links:
                    Link.objects.create(**link)
            self.stdout.write(
                self.style.SUCCESS("Instances of Link successfully created!")
            )
        except IntegrityError:
            self.stdout.write(
                self.style.WARNING("These Link instances exists already!")
            )
        except Exception as e:
            self.stdout.write(self.style.ERROR(f"An unexpected error occurred: {e}"))

You may ask, why not use django-admin dumpdata to reuse the data from my database? Quite simply, I changed the model attributes and the data structure was no longer the same. So I needed another way to recreate all the data (which is a lot of content) every time my model structure changed.
