This is a simple scaffold app that allows you to manage vessels.

There are two areas for this:

• The main area, accessible from the root URL /

• The admin area, accessible from /admin/vessels

Currently every URL is accessible and there is no access control.

You need to do the following:

• Add access control for the admin area.

• When somebody who is not an admin adds a new, or edits an existing vessel successfully, send a notification email to [email protected] with the following details:

  • The IP of the client who added/edited the vessel

  • The new record, if it is a new record

  • The changes, if it was an edit of an existing record

  • A link in the admin area, where an admin user can view the record

• Fix the bug: As a regular user, I can’t create a vessel because fee_pc can’t be blank. This attribute is required for a vessel to be considered valid, but can only be set/changed by an admin user.

• BONUS: add test cases for the above requirements.

Use git to commit your changes.
