Hi Tomasz, Unfortunately I'm now pretty sure you are affected by an ORM bug when annotating over multiple multi-valued relationships[1]. Since this bug is 7 years old and seemed quite hard to fix it was recently documented as a limitation[2]. >From this point I suggest you CC on ticket to get n

Re: Django 1.9 ./manage.py migrate error

Hi, thanks for the reply. So, did you have a db in the project? I cloned the project again and tried to create the db from the model, but using your suggestion doesn't work. I can only get 1.9 working if I already have a db from 1.8, but not creating a new one from scratch. Neither the first or
