README

This is a test app for testing paper_trail nested associations.

Model structure

Book

• has_many authors through authorships
• has_many editions
  • has_one cover -> changed to has_many
• has_one isbn
• has_many covers -> added in order for the PT-AT gem to work

Edittion

• has_one cover -> changed to has_many

Person

• has_many books through authorships

setup

1. bundle install
2. rails db:create
3. rails db:migrate
4. rails db:seed # optional, will create sample person

How to use the app

• Create a new Person.
• Create a new Book.
• Input Book data, save the Book.
• Edit the created Book, change the cover value, then save the Book.
• Click Versions of the book.
• Click Restore to this version.

Expected behavior

The Restore should be able to restore all associations, including edition cover.

Current behavior

The Restore can restore all associations but the edition cover.

The Restore can now restore cover, too!

Possible issue

The documentation for PT-AT stated:

If you want to include nested associations simply add :through relationships to your model.

But no example is given.
