South 0016 Migration MySQL about aldryn-newsblog HOT 9 CLOSED

I'm able to reproduce this issue using MySQL 5.6.22. OP reported he was using 5.6.17 here. OP is running Django 1.6.x and Python 2.7.9.

from aldryn-newsblog.

Tested some more with MySQL query logging on. I've taken part of the log that seems to be migration 0016. What I see is that the entire migration is completed, but then the constraint is added again which gives the error and a rollback.

I've tested with MySQL 5.6.23 and 5.5.41, both seem to have the same problems. I use Django 1.6, South 1.0.2 and MySQL-python 1.2.5.

I've now tried it with and without using 'init_command': 'SET storage_engine=INNODB'... no difference. All tests run fine. It'd be easy enough for me to make the change that I suggested to make it work, but I think its more important to understand why. Also, can you supply the output of a pip freeze?

@Nalanae are you able to run the tests in the aldryn-newsblog package?

pip install -r test_requirements/django-1.6.txt
./test

from aldryn-newsblog.

When I run the tests against SQLite or MySQL they run fine. However, when I check a MySQL query log of just the testrun, I can't find any mention of the problematic constraints. I'll investigate further into the log.

If you want to have a look into the log: https://dl.dropboxusercontent.com/u/6635899/mysql.log.zip

When I change the call to djangocms-helper to use migrations I can force the error.

djangocms-helper aldryn_newsblog --cms test --migrate --extra-settings=test_settings $@

@Nalanae, @mrgix Very useful, thanks to both of you.
