Troubleshooting your TOM

When first installing or later updating your TOM, you may run into a few common issues. Fortunately, you can stand on our shoulders and hopefully find a solution here!

Check that you’ve migrated

Oftentimes, updating the TOM Toolkit requires running migrations. Usually, a directive to do so will be included in the release notes, or Django will remind you that You have unapplied migrations. If you don’t happen to see those, you may also see a <tablename.column> does not exist when you load a page, or an error about an applabel. Those are generally indicators that you need to run a database migration.

You can confirm that you are missing a migration by running:

./ showmigrations --list

Migrations that have been applied will have a [X] next to them, so make sure they all have one. If any are missing:

./ migrate

Make sure you’re in a virtual environment

Everyone forgets to activate their virtualenv from time to time. If you get a missing package or some such, ensure that you’ve activated your virtualenv:

source env/bin/activate

You may need to adapt the above for your particular shell. Also be sure that the virtualenv was created with a compatible version of Python, and that you installed your dependencies into that virtualenv.

Check your shell

It’s a small development team, and we all use bash. We’ve seen some issues with people running zsh, fish, and even csh. You may need to adapt the commands given in the setup guide.
