thankx guys
but
still there is a problem

User.find(:all, :order => ‘id DESC’, :limit=>1)

and

Model.find(:last)

both return “#” mark only. whats the reson? i want last index id

5

ok then say

lst_id = Model.find(:last).id
puts lst_id.inspect

hope 'll get this

as Model.find_last retunrns the entire last record

If you want only the id of the last entered data then try this,
User.maximum(‘id’)
This will return the maximum id which will be anyways the last one.
