AttrCleaner

Cleans up your model attributes. Strips leading and trailing space, and turns empty strings into nil.

Tested against Rails 4.2, 5.0, and 5.1.

Install

If you're using Rails with ActiveRecord all you need to do is:

gem "attr_cleaner"

Simply pass a list of attributes that you want to clean:

attr_cleaner :title, :body

Child models will inherit the attribute writers from their parent.

AttrCleaner works by generating attribute setters and should work with most ORMs.

To get AttrCleaner working with your ORM just include it into your models:

include AttrCleaner::Model
