Populating the database with data - are the docs wrong or my setup?

Hello,

the docs suggest an approach to populate the database with the initial data this way: http://pytest-django.readthedocs.io/en/latest/database.html#populate-the-database-with-initial-test-data

I created a small demonstrational app that uses exactly that approach. Unfortunately, I am not able to see the test data anywhere else except the first test case ran. In the first test case everything is okay. In the subsequent test cases, the data are gone from the database.

Am I doing something wrong? Here is the conftest: https://github.com/mpasternak/pytest-django-pytest-splinter-test/blob/master/demo1/demo1_app/conftest.py and here are my tests: https://github.com/mpasternak/pytest-django-pytest-splinter-test/blob/master/demo1/demo1_app/tests.py#L21

When I change the scope of the django_db_setup fixture to function, everything comes back to normal.

So, is this a bug or should I create a PR to update the documentation? Is it somehow related to this issue: https://github.com/pytest-dev/pytest-django/issues/329 ?

Start with the linked database documentation, then inspect the referenced conftest.py and tests.py around line 21, comparing django_db_setup with function scope. Reproduce the differing behavior across test cases and compare it with issue #329; done means determining whether this is a fixture bug or a documentation/setup problem and recording the required correction.
