Determine if ActiveRecord Object is New
How can I check if an ActiveRecord object is new or is already persisted?
Solution 1:
An ActiveRecord object lifecycle:
1.new record
item = Item.new
item.new_record? #=> true
2.persisted
item.save
item.persisted? #=> true
3.changed
item.name = "other"
item.changed? #=> true
4.destroyed
item.destroy
item.destroyed? #=> true
Solution 2:
#new_record? does just that:
object.new_record?
