# example-activerecord-lib

This is an example of how to use ActiveRecord in a Ruby library, _not_ a Rails

app or Rails engine.

```shell

$ bundle install

...

$ irb -r bundler/setup -Ilib -r library

>> Library.connect

[Library::Author(id: integer, name: string),

 Library::Book(id: integer, title: string),

 Library::BookAuthor(id: integer, author_id: integer, book_id: integer)]

>> author = Library::Author.create(name: 'Neal Stephenson')

=> #

>> author.books.create(title: 'Snowcrash')

=> #

>> exit

$ sqlite3 database.sqlite3

sqlite> .tables
