Checklist

• I have verified that I am using a GIS-enabled database, such as PostGIS or Spatialite.
• I have verified that that issue exists against the master branch of django-cities.
• I have searched for similar issues in both open and closed tickets and cannot find a duplicate.
• I have reduced the issue to the simplest possible case.
• I have included a failing test as a pull request. (If you are unable to do so we can still accept the issue.)

Steps to reproduce

Version

Django==1.11.7
django-cities==0.5.0.5
Python 3.5

1. Run ./manage.py test in a django project with django-cities installed (via pip install)
   Please note that the database is being run in a Docker container.

Docker build run command

docker build _docker/postgres --tag wiredapps_postgres
docker run -itd -p 6543:5432 --env-file _docker/postgres/.env --name wiredapps_postgres wiredapps_postgres

Expected behavior

Tests to run

Actual behavior

An error occurs similar to the one found in #129, but migrations run fine.

Creating test database for alias 'default'...
Got an error creating the test database: database "test_wiredapps" already exists

Type 'yes' if you would like to try deleting the test database 'test_wiredapps', or 'no' to cancel: yes

The above exception was the direct cause of the following exception:

Please give me more information to troubleshoot your issue:

1. Does the cities_country table actually exist in your test database?
2. Does django-cities work outside of Docker?
3. What is the contents of the django_migrations table in your test database?
4. What is the output of Django's migrations when you run tests?

[kiddhustle]

Hi there, so I've just had a look at the test database:

1. the cities_country does not exist in my test database
   The only tables I can see in the test database are:

 List of relations
 Schema |       Name        | Type  |   Owner   
--------+-------------------+-------+-----------
 public | django_migrations | table | <OWNER>
 public | spatial_ref_sys   | table | <OWNER>

2. I have just tried django-cities outside of docker and I get the same outcome
3. On inspection there are actually no rows inside the django_migrations
4. When runnning tests there is actually no output from the migrations (see the error message above), any idea why this is? I thought the migrations should run automatically when the test database is create?

[blag]

If there are no rows in django_migrations, then the Django migrations did not run. Something is interrupting your tests such that the migrations aren't working. Double check the migration files in your project, or try commenting out apps one by one until migrations work, then adding apps back in one by one to figure out which app is messing up migrations.

As far as I can tell, this isn't an issue with django-cities, this is an issue with your migrations.

[kiddhustle]

So after seeing that migrations were actually being run I started thinking the same and that this was not a problem with django-cities. After deactivating (and re-activating one by one) my installed apps in settings.py I realised that I had an installed app with no migrations. When this was de-activated tests ran as expected.

I think the app migrations came into being in this state after I was squashing migration. Because I am not currently using this app I never go round to migrating it.

I have now removed this app from INSTALLED_APPS and everything works as expected.

Thanks for helping me spot my error and sorry for the confusion!

Good to hear you got things working, I'm glad we got to the bottom of your issue! 😄
