The changes did not register in your schema: https://github.com/hondoh/ODOT/blob/master/db/schema.rb

Make sure you run rake db:migrate and rake db:migrate RAILS_ENV=test successfully.

I don't understand why the changes would not have registered. These are the results from the two console commands that I used. I wasn't sure if they worked either so I tried using the commands again but when I type them in they only show me the warning and do not appear to do anything.

The last line "AddCompletedAtToTodoItems: migrated (0.0000s)" says the migration was done and the schema should be changed. It works on my machine when I download your code and adds this column properly.

I just downloaded my project files and ran the commands again and they worked this time and gave me a different result in the command line as well. I really appreciate all the help you've been giving me with this application. It would have been a nightmare without you.
