Problem:
Boolean values were being treated as strings, and were throwing an error on the index page.
They were also being displayed in a text box on the form pages, which wasn't ideal.
See https://trello.com/c/AhvzdRx4
Solution:
- Add
Administrate::Field::Boolean
for presenting boolean values, and present them as a checkbox on form pages. - Add
Customer#email_subscriber
column for testing the boolean field in a feature spec.
