I have inherited a website built with Python 3.4, Django 1.10 with a MySQL database that has been built with no tests in place except for some old, unused legacy tests. I have since started writing tests but experience an error when trying to run manage.py test (this works for about 5 minutes on removing the old db before the exception is raised)
Creating test database for alias 'default'... Got an error creating
the test database: (1007, "Can't create database 'test_rmpublic';
database exists") Type 'yes' if you would like to try deleting the
test database 'test_rmpublic', or 'no' to cancel: yes Destroying old
test database for alias 'default'... Traceback (most recent call

I looked through all the migration files and couldn't see any reference to establishment_id. Thinking that it might be a problem with the old test_db, I used the hacky but accepted answer described in this question to use sqlite3 as a test db instead and got a new error:

Apologies for the bloated stack traces. Any help would be great.
