ActiveResource::Dirty

ActiveResource::Dirty is a monkey patch that supports ActiveModel::Dirty methods in ActiveResource.

Provides a way to track changes in your object. For example:

person = Person.find(1)
person.changed?         # => false
person.name = 'Frank'
person.changes          # => {"name"=>[nil, 'Frank']}
person.name_was         # nil
person.save
person.changes          # => {}
person.previous_changes # => {"name"=>[nil, 'Frank']}

It uses the http PATCH method instead of PUT, and sends in the body only the attributes that have changed. This feature requires the flag patch_updates.

class Person < ActiveResource::Base
  self.site = 'http://someapi.com'
  self.patch_updates = true
end

person = Person.find(1)
person.name = 'Frank'
person.save
# Sends this request:
# PATCH http://someapi.com/people/1.json
# {"name":"Frank"}
#

This is a monkey patch that overrides methods from both ActiveResource and ActiveModel::Dirty (the latter one only for ActiveResource::Base. It does not affect ActiveModel for other uses). Any change in this methods in future versions can lead to unexpected results. So use with caution.

Add this line to your application's Gemfile:

gem 'active_resource-dirty'

And then execute:

$ bundle

Or install it yourself as:

$ gem install active_resource-dirty
