Rails: how to find record before last?

Question

I can find last record in my table like in example below, but what if I want to find record before last, e.g. (last-1) or (last-2)..? I have this example in my each loop:

Answer 1

Even if accepted answer works:

Table.where(:dogovor_id => p.id).order("id DESC").first           # last
Table.where(:dogovor_id => p.id).order("id DESC").offset(1).first # last - 1
Table.where(:dogovor_id => p.id).order("id DESC").offset(2).first # last - 2

'first' method is an array method, so concerning performance its better to use 'limit' method which is an ActiveRecord method and attaches LIMIT clause to SQL query:

Table.where(dogovor_id: p.id).order(id: :desc).offset(1).limit(1) # last - 1
