** (Ecto.ConstraintError) constraint error when attempting to delete struct:

[nelsonic]

As part of Automatically Creating a New API Key during App creation #97
we are creating a foreign key constraint between API Keys and Apps.
Which means we get the following error when we attempt to Delete an App:

  1) test delete app deletes chosen app (AuthWeb.AppControllerTest)
     test/auth_web/controllers/app_controller_test.exs:82
     ** (Ecto.ConstraintError) constraint error when attempting to delete struct:

         * apikeys_app_id_fkey (foreign_key_constraint)

     If you would like to stop this constraint violation from raising an
     exception and instead add it as an error to your changeset, please
     call `foreign_key_constraint/3` on your changeset with the constraint
     `:name` as an option.

     The changeset has not defined any constraint.

Todo

• Fix it!

I'm going to define the deleted status in #101 and then use it in App.delete_app/1. #BRB

Fixed. ✅ (but not with out a lot of head-scratching ...) 🙄
