Active Record - Get the second, third.. item in a database (without ID)

Question

How to I retrieve the second, third .. entries in a database. I don\'t want to use the auto incrementing id generated by rails.

As I am deleting entries from my data

Answer 1

Model.second was added to Rails 4.1.8.

So you can use it on Rails versions equal to or greater than that.

.third, .fourth and .fifth were also added to ActiveRecord::FinderMethods.

Answer 2

what you need is

#n=2,3,4 etc    
.limit(1).offset(n) 

Answer 3

Say you want the fourth user:

 @users = User.limit(4)
 @fourth_user = @users[3]

Concerning your second question, destroy_all should do the trick since it triggers all callbacks. Be sure to add :dependent => :destroy in your relationships.
