When I try to run my unittest, this is what I get:
python manage.py test dbank --settings=databank_web.settings.dqs.dev_hooman
Creating test database for alias 'default'...
Creating test database for alias 'global'...
Creating test database for alias 'optin_db'...
Creating test database for alias 'vpd3'...
Creating test database for alias 'user_db'...
Creating test database for alias 'vpd1'...
Creating test database for alias 'vpd2'...
.

Destroying test database for alias 'default'...
Warning: Table 'mysql.proc' doesn't exist
It couldn't destroy the database. It gets better, when I rerun the test:
python manage.py test dbank --settings=databank_web.settings.dqs.dev_hooman
Creating test database for alias 'default'...
Creating test database for alias 'global'...
Got an error creating the test database: (1007, "Can't create database 'test_dqs12_full2'; database exists")
Type 'yes' if you would like to try deleting the test database 'test_dqs12_full2', or 'no' to cancel: yes
Destroying old test database 'global'...
Got an error recreating the test database: Table 'mysql.proc' doesn't exist
Any idea why this is going wrong?
Running latest homebrew + mysql-5.6.21 + Django 1.5.5
I have finally found the reason.
Our application has around 7 databases. When I was about to drop them manually to get a clean state, I accidentally also dropped the mysql database. This database should not be ever deleted, as it contains vital information about the root user.
When I realised this, I tried to mitigate by reinstalling MySQL via brew.
brew uninstall mysql
brew install mysql
This worked and mysql database showed up again when I ran show databases;, however the problem persisted. Thats when I came here for help.
As it seems things are a bit more complicated than that with brew. This is how I got it working again:
1) brew uninstall mysql
2) sudo rm -r /usr/local/var/mysql/
3) brew install mysql
4) unset TMPDIR
5) mysql_install_db --verbose --user='whoami' --basedir="$(brew --prefix mysql)" --datadir=/usr/local/var/mysql --tmpdir=/tmp
6) mysql.server restart
7) mysql_secure_installation
Now it works. Hope this helps other fellow mac users. Thanks.
Well, there are two errors indicating that the mysql.proc table is missing. You might be able to generate it running mysql_update.
