Description
Very strange behaviour of the Django ORM while testing (now I am using pytest)
I have two apps "books" and "replies".
The app "books" has two models http://pastebin.com/gDMi7UpU
The app "replies" has one model http://pastebin.com/u9FabQQA
For create new objects I am using factories for replies - http://pastebin.com/pGtiwS2m, for books and writers - http://pastebin.com/NQ6AWxib
While testing methods of queryset of the model Book I got error, where it should not be
A file querysets.py of the app "books" http://pastebin.com/FVnLLzxK
Tests for the file querysets.py of the app "books" http://pastebin.com/rmpDm0Ae
For testing I am using the pytest with next configuration in a file pytest.ini
[pytest] addopts = -s --reuse-db --ff --maxfail=1 apps/books/tests/test_querysets.py::Tests DJANGO_SETTINGS_MODULE=config.settings.development
Run test as next py.test
Traceback http://pastebin.com/Vv96XLzm
After many time googling and dipping in the Django`s code by the traceback I decided it is bug in the Django
I think it is the problem related with that models the Book and the Reply is related by help the field GenericRelation, but I don`t found facts for it.
Sorry for my grammar mistakes, I was no originally an English
If need another codes from my project, please tell about it
