    We could not find your database: #{db_name}. Which can be found in the database configuration file located at config/database.yml.

    To resolve this issue:

    - Did you create the database for this app, or delete it? You may need to create your database.
    - Has the database name changed? Check your database.yml config has the correct database name.

    To create your database, run:\n\n        bin/rails db:create
