Fails on [Migrate apps.common]

Tried from a fresh VM provision, twice:

vagrant43                  : ok=5    changed=1    unreachable=0    failed=1 

Only thing I've changed is in the vagrantfile, I changed the port forward to 8585 from 8080.

I'm running debian host (Hydrogen Linux, actually), with VirtualBox 5.0.10. The guest additions for 5.0.10 also failed to install for 5.0.10. I'll have to go hunt that error down if it's relevant.

Good find! I forgot to update the Ansible scripts as I upgraded the Django version - the migration process is a little different now. I'll publish a patch within the next few days. For now you can try to run the database migrations manually: https://docs.djangoproject.com/en/1.8/ref/django-admin/#django-admin-migrate

[thomas-frantz]

Hey, thanks!

I'll try that and report.

So, I had actually tried doing doing it manually. Though, I don't have much experience with python or django, so I'm not quite sure what the format of the command should be.

I've tried:

./manage.py migrate eve_db

which results in:

(element43)~element43/element43/webapp (master ✘)✹✭ ᐅ ./manage.py migrate eve_db
Operations to perform:
  Apply all migrations: eve_db
Running migrations:
  No migrations to apply.
  Your models have changes that are not yet reflected in a migration, and so won't be applied.
  Run 'manage.py makemigrations' to make new migrations, and then re-run 'manage.py migrate' to apply them.

As well as:

./manage.py migrate eve_db apps.common

which results in:

CommandError: Cannot find a migration matching 'apps.common' from app 'eve_db'.

And

./manage.py migrate apps.common

Which results in the same error above.

I've tried

./manage.py makemigrations

Which results in:

(element43)~element43/element43/webapp (master ✘)✹✭ ᐅ ./manage.py makemigrations

So, not quite sure what the command should be.

edit:

Also tried:

(element43)~element43/element43/webapp (master ✘)✹✭ ᐅ django-admin migrate apps.common

So, I got the django-admin command to work (I had to add /home/element43/element43/webapp to the PYTHONPATH). Now it's giving the same things as before when just running ./manage.py

Feel free to ask if you have any more questions.

Just wanted to let you know it worked flawlessly. Thanks!
