How to migrate Django models from mysql to sqlite (or between any two database systems)?

Question

I have a Django deployment in production that uses MySQL.

I would like to do further development with SQLite, so I would like to import my existing data to an SQLite dat

Answer 1

use

manage.py dumpdata > your_file.json

to export your data from the production system (docs).

Then move the file on the development system and run

manage.py loaddata your_file.json

You can also put the file in your_app/fixtures folder with name "initial_data.json" and it will be automatically loaded when you run "manage.py syncdb" (docs).

Answer 3

If you have contenttypes in installed app

INSTALLED_APPS = (
    'django.contrib.contenttypes',
)

Use script like what for copying you entry to new base:

from django.contrib.contenttypes.models import ContentType

    def run():

        def do(Table):
            if Table is not None:
                table_objects = Table.objects.all()
                for i in table_objects:
                    i.save(using='slave')

        ContentType.objects.using('slave').all().delete()

        for i in ContentType.objects.all():
            do(i.model_class())

Have you tried using manage.py dumpdata > datadump and then when the new database is set up correctly, use python manage.py loaddata datadump?
