Scenario instructions:

Environment instructions:

You need to create the Ruby on Rails project from scratch, after the command `rails new . --api` was run.

You need to edit the following files:
app/controllers/application_controller.rb
app/models/application_record.rb
config/application.rb
config/environments/development.rb
config/routes.rb


Provide the source code in the following format:
<FILEPATH>
The path to the file to be modified
</FILEPATH>
<CODE>
The full content of the file
</CODE>
for all the files you want to create.

Example:
<FILEPATH>
path/to/file.py
</FILEPATH>
<CODE>
def hello_world():
    pass
</CODE>



Use only SQLite as a database. Do not use MySQL, Redis, or any other storage.
Configure SQLite to use database file `db.sqlite3` in config/database.yml
Do NOT provide Gemfile or Gemfile.lock file. Make sure to include the right frameworks in config/application.rb - e.g. require "active_storage/engine"
Do NOT use sprockets or other asset pipeline. Do NOT use config.assets in config/environments/development.rb.
The command `bin/rails server --binding 0.0.0.0 --port 5000` will start the app.
