How can I easily convert a Django app from mySQL to PostgreSQL?

Question

Has anyone done this? Is it an easy process? We\'re thinking of switching over for transactions and because mysql seems to be \"crapping out\" lately.

Answer 1

1. python manage.py dump.data >> data.json

2. Create database and user in postrgesql

3. Set your just created database in postrgesql as default database in django settings or use param --database=your_postrgesql_database next steps

4. Run syncdb for create tables.

   python syncdb [--database=your_postrgesql_database] --noinput

5. Create dump without data, drop all tables and load dump. Or truncate all tables (table django_content_type whith data which can be not equals your old data - it is way to many errors). At this step we need empty tables in postgresql-db.

6. When you have empty tables in postgresql-db just load your data:

   python manage.py loaddata data.json

And be fun!
