Rails: how to find record before last?
Table.where(:dogovor_id => p.id).order("id DESC").first # lastTable.where(:dogovor_id => p.id).order("id DESC").offset(1).first # last - 1Table.where(:dogovor_id => p.id).order("id DESC").offset(2).first # last - 2
Rails 4:
Model.last(2).firstIn Rails 5+ you can use new self-explanatory accessor methods:
Model.second_to_lastModel.third_to_lastYou can also use negative indices.
Second to last:
Model.all[-2]The 10th to last:
Model.all[-10]NB: As pointed by @AndrewSchwartz, this method can be more problematic (consuming) on large tables. This method first loads all the records and then processes them, whereas second_to_last generates more optimized query with LIMIT and OFFSET
