Activeresource::SaveChanged

This gem is to limit the saving of changes to an Active Resource object to only the field that have changed.

Installation

Add this line to your application's Gemfile:

gem 'activeresource-save-changed'

And then execute:

$ bundle

Or install it yourself as:

$ gem install activeresource-save-changed

Usage

Specify changed fields

Instead of calling save on your AR objects, call save_fields('list,of,field,names'). You can also call save_fields!('list,of,field,names') to raise errors on failure.

Detect changes automatically

Wrap your changes in a block and the changes will be automatically detected and saved when the block is complete.

my_obj.save_changes {

my_obj.field1 = new_value
my_obj.field2 = same_as_current_value

}

Will result in the object being persisted with only field1 being sent to the server.

There is also an equivalent save_changes! method.
