Agile Web Development

Additions to ActiveRecord:
.changed? – have model attributes changed since save?
.saved? – have all attributes been saved to the database? (opposite of .changed?)
Simple! it keeps track of whether or not an ActiveRecord model has attributes that have changed since the last save.
Notes:
– New records are treated as changed, even if no attribute has explicitly been set.
– “saved?” is the opposite of “changed?”
examples:
>> sam = Person.find_by_name(‘sam’)
>> sam.changed?
=> false
>> sam.saved?
=> true
>> sam.age = 24
=> 24
>> sam.changed?
=> true
>> sam.saved?
=> false
>> sam.save
>> sam.saved?
=> true
