django-clear-tables 0.1.1

django manage.py task that clears the content of the django Permission and ContentTypes tables, after an initial migration, to make manage.py loaddata work.

django-clear-tables

This is a simple django-app, registering a task called django_clear_tables.

It will delete the contents of django's Permission and ContentTypes models so you can load data from a fixture without problems. Normally, an initial migrate will create permission and content-type data. If you want to clone data from another instance, to a fresh database, this data will clash with the loaddata command.

Be careful because it can also easily mess up your existing database.

Install it with:

pip install django-clear-tables

Usage is as follows:

Add django_clear_tables to INSTALLED_APPS in your django settings.py, then:

# initially setup the database
rm db.sqlite3  # or using mysql, pg, ...
./manage.py migrate
# wipe the initially created data
./manage.py django_clear_tables
# load a fixture from somewhere else
./manage.py loaddata dumpdata-from-another-instance.json
